灯光设计的书籍有哪些

灯光设计的书籍有哪些?一起来了解一下吧。1、《室内灯光设计》从三个方面介绍了灯光设计:灯光与室内空间、灯光与室内装饰以及灯光与室内氛围。通过大量的图片展示和详细的文字介绍说明,读者将会清楚的感受到灯光在室内设计中的角色以及它所带来的影响力。这本书对室内设计师以及相关读者是一个十分有价值的借鉴。2、《Ignite: The Art of Lighting Design Alliance》照明设计联盟的目标融合建筑和室内设计,创造令人印象深刻的空间效果。通过良好运用隐蔽光、自然光和装饰灯具制造具有动感的环境。认真执行整个项目设计理念的每一个阶段以保证取得成功。这本176页的精美彩图,通过大量优秀作品反映出照明设计联盟的设计理念。特色项目包括:洛杉矶国际机场总体规划,洛杉矶、威尼斯港口,亚特兰蒂斯度假村第三阶段,芝士厂等等。这是一本提供了很多追求建筑照明的创新和富有想象的设计方案。3、《Light Innovations》精选了很多项目,这些项目充分体现了灯光设计的独特创意,折射出艺术美的信息,并营造灯光、空间、色彩和阴影的完美氛围,更广意义上来说,是利用灯光来创造更大的建筑空间。拓展小知识设计师必备的灯光设计教程是什么1、明确照明设计与灯光设计说到灯光设计,大家肯定也会想到照明设计,有些朋友会认为这两个没什么不同,因为从字面上很难区分,但是扬叔可以负责任的告诉大家,这两个词所体现的东西是不一样的!(1)照明设计照明设计以光的功能作为设计重点,不讲究气氛与情感,但是讲究控光,了解光的参数,把握光影的虚实。(2)灯光设计灯光设计以光的视觉效果为设计重点。其是具有艺术性的,有气氛,有层次,有情感,反而实用性不是它的重点。2、灯光设计原则(1)了解空间重点在灯光设计前期,我们就必须清楚地了解,哪些地方需要提升灯光亮度来突显重点,哪些地方的灯光饱和度需要更高,哪些地方需要完整的光,哪些地方需要反射的光。(2)考虑空间整体灯光设计要考虑空间得整体。我们可以把空间不同得元素加起来,先找到空间得设计元素和重点,再想怎么最适合得灯光去提升它,从而提升整体的灯光效果。3、灯光设计重要性灯光是空间的灵魂,灯光造价只占了室内空间的5%,确承载了100%的氛围营造。灯光可以说是一个较灵活及富有趣味的设计元素,可以成为气氛的催化剂,是室内空间的焦点及主题所在。以上就是小编今天的分享,希望可以帮助到大家。

关于创新的英语名言【三篇】

  【篇一】 幸运之神总是降临到勇于创新的人身上。Luck always comes to those who dare to innovate. 自我满足是可悲的,不创新便会被社会抛弃,应永远保持强烈的学习欲望。才能立于不败之地。 Self-satisfaction is tragic. If we do not innovate, we will be abandoned by the society. We should always maintain a strong desire to learn. Only then can we remain invincible. 正确对待前人理论,学百家之长,自主创新。 Correct treatment of previous theories, learn from the strengths of a hundred schools, and innovate independently. 凡事力争的可能性,但必须做最坏的准备。做创新的科研工作更是如此。 Everything strives for the best possibilities, but must be prepared for the worst. This is especially true for innovative scientific research. 科学技术史表明,过多的知识信息有时反倒会妨碍和限制创新。 The history of science and technology shows that too much knowledge and information can sometimes hinder and restrict innovation. 严格自律出廉政,服务创新谋发展。 Strict self-discipline, clean government, service innovation and development. 有了精神的实验和观测作为研究的依据,想像力便成为自然科学理论的设计师。 With spiritual experiments and observations as the basis for research, imagination becomes the designer of natural science theory. 将爱形容为美丽的,是不了解爱的人;将爱形容为丑陋的,是自以为了解爱的人。 To describe love as beautiful is to say that one does not know love; to describe love as ugly is to say that one knows love. 这种创新代表着社会所需要的东西:首创性、进取心和创造精神。 This kind of innovation represents what society needs: initiative, enterprising spirit and creative spirit. 多思考才能创新,勤检讨才有进步。 Only by thinking more can we innovate, and only by reviewing diligently can we make progress. 人可以老而益壮,也可以未老先衰,关键不在岁数,而在于创造力的大小。 People can grow old and strong, or they can decline before they grow old. The key is not age, but creativity. 在创造家的事业中,每一步都要三思而后行,而不是盲目地瞎碰。 In the cause of a creator, think twice before you act, not blindly. 观念创新就是目标创新,目标创新就是提出别人认为不可能达到的目标,并用创新的办法实现它。 Idea innovation is goal innovation, goal innovation is to put forward goals that others think are impossible to achieve, and use innovative methods to achieve it.  【篇二】 能正确地提出问题就是迈出了创新的第一步。The first step in innovation is to correctly ask questions. 异想天开给生活增加了一分不平凡的色彩,这是每一个青年和善感的人所必需的。 Fantasy adds an extraordinary color to life, which is necessary for every young man and sentimental person. 生活的真谛在于创新,生活的理想在于远大,生活的艺术在于选择,生活的乐趣在于追求。 The essence of life lies in innovation, the ideal of life lies in loftiness, the art of life lies in choice, and the pleasure of life lies in pursuit. 人应当使自己的面貌日新月异,要像坚硬而有韧性的金属那样经得起任何斗争的锻炼。 Man should change his appearance with each passing day, and stand up to any struggle like hard and tough metal. 没有创新,就不可能有合理的,尤其是有效的管理。 Without innovation, there can be no reasonable, especially effective management. 人类的创新之举是极其困难的,因此便把已有的形式视为神圣的遗产。 Human innovation is extremely difficult, so the existing form is regarded as a sacred heritage. 如果试图改变一些东西,首先应该接受许多东西。 If you try to change something, you should first accept many things. 一个没有创新潜质的民族,难以屹立于世界先进民族之林。 A nation without innovation potential can hardly stand in the forest of advanced nations in the world. 创新将是以知识融合经验,提升制造科技的核心竞争力。 Innovation will enhance the core competitiveness of manufacturing technology by integrating knowledge with experience. 敏于观察,勤于思考,善于综合,勇于创新。 Be sensitive to observation, diligent in thinking, good at synthesis, and dare to innovate. 创新有时需要离开常走的大道,潜入森林,你就肯定会发现前所未见的东西。 Sometimes innovation needs to dive out of the avenue and into the forest, and you"ll surely find something you"ve never seen before. 在科学上,每一条道路都应该走一走。发现一条走不通的道路,就是对于科学的一大贡献。 In science, every road should be taken. Finding a way out is a great contribution to science.  【篇三】 非经自己努力所得的创新,就不是真正的创新。 Innovation is not real innovation unless it is achieved through one"s own efforts. 渐进就是守旧。因此经营理念创新,就要反渐进,务必一步到位。 Gradual progress is conservative. Therefore, the innovation of business philosophy should be counter-gradual and must be in place step by step. 创新不是由逻辑思维带来的,尽管最后的产物有赖于一个符合逻辑的结构。 Innovation is not brought about by logical thinking, although the final product depends on a logical structure. 对于一个艺术家来说,如果能够打破常规,完全自由进行创作,其成绩往往会是惊人的。 For an artist, if he can break the rules and create freely, his achievements will be amazing. 没有创新精神的人永远也只能是一个执行者。 A person without an innovative spirit can never be more than an executor. 蓝海战略是以创新为中心的战略,强调的是无人竞争的、全新的市场空间和全新的商机。 The Blue Ocean Strategy is an Innovation-centered strategy, which emphasizes the unparalleled, brand-new market space and new business opportunities. 商品开发离不开创新构想,创新构想是人类智慧中最美丽的花朵。 Commodity development is inseparable from innovative ideas, which are the most beautiful flowers in human wisdom. 或者创新,或者消亡。尤其是在技术推动型产业,再也没有比成功消失得更快的了。 Either innovation or extinction. Especially in technology-driven industries, there is no faster disappearance than success. 在自然科学中,创立方法,研究某种重要的实验条件,往往要比发现个别事实更有价值。 In natural science, it is often more valuable to create a cubic method to study some important experimental conditions than to discover individual facts. 教育是知识创新、传播和应用的主要基地,也是培育创新精神和创新人才的摇篮。 Education is not only the main base of knowledge innovation, dissemination and application, but also the cradle of cultivating innovative spirit and innovative talents. 创新就是创造一种资源。 Innovation is the creation of a resource. 科学给人以确实性,也给人以力量。只依靠实践而不依靠科学的人,就像行船人不用舵与罗盘一样。 Science gives people both certainty and strength. A man who depends only on practice and not on science is like a sailor who does not need a rudder or a compass. 对所有的大胆创新,要做最坏的打算,尽的努力! For all bold innovations, we must prepare for the worst and do our best! 应当热爱科学,因为人类没有什么力量是比科学更强大、更所向无敌的了。 We should love science, because there is no human power stronger and more invincible than science.

u200b2019年6月大学英语四级阅读理解训练:科学技术

2019年6月大学英语四级阅读理解训练:科学技术   Discoveries in science and technology are thought by "untaught minds" to come in blinding flasher or as the result of dramatic accidents. Sir Alexander Fleming did not, as legend would have it, look at the mold on a piece of cheese and get the idea for penicillin there and then. He experimented with antibacterial substances for nine years before he made his discovery. Inventions and innovations almost always come out of laborious trial and error. Innovation is like soccer; even the best players miss the goal and have their shots blocked much more frequently than they score.   They point is that the players who score most are the ones who take the most shots at the goal??-and so it goes with innovation in any field of activity. The prime difference between innovators and others is one of approach. Everybody gets ideas, but innovators work consciously on theirs, and they follow them through until they prove practicable or otherwise. What ordinary people see as fanciful abstractions, professional innovators see as solid possibilities.   "Creative thinking may mean simply the realization that there"s no particular virtue in doing things the way they have always been done," wrote Rudolph Flesch, a language authority. This accounts for our reaction so seemingly simple innovations like plastic garbage bags and suitcases on wheels that make life more convenient: "How come nobody thought of that before?"   The creative approach begins with the proposition that nothing is as it appears. Innovators will not accept that there is only one way to do anything. Faced with getting from A to B, the average person will automatically set out on the best-known and apparently simplest route. The innovator will search for alternate courses, which may prove easier in the long run and are bound to be more interesting and challenging even if they lead to dead ends.   Highly creative individuals really do march to a different drummer.   67. What does the author probably mean by "untaught mind" in the first paragraph?   [A] A person ignorant of the hard work involved in experimentation.   [B] A citizen of a society that restricts personal creativity.   [C] A person who has had no education.

One of them will enable us to generate *** all amounts of energy to supplement the electric power we use in our homes. "You can do micro-electronic generation." Bernie Meyerson is vice president of Innovation at IBM. "For instance, you can have somebody in the third world who has access to a phone or a *** art phone, but doesn"t have access to a power grid which is a very mon thing, and literally in a shoe has something that recovers energy from walking and can charge the battery to enable that person to actually bee connected with the rest of the world." Another innovation will make those hard-to-remember passwords obsolete. Soon, in order to access our e-mail or bank account, we"ll use a technology known as biometrics. "Imagine that things recognize you, you walk up to an ATM, it takes one look says, "Yep, you"re you.""   就在美国国际商用机器公司进入其第二个世纪时,这家美国技术公司公布了它的第六个五五计划,一份关于5项创新技术的清单,公司预期将在五年之内实现这些创新技术。 其中的一个会帮助我们产生少量能量来补充家用电能。 伯尼u2022麦叶森是IBM公司创新部的副总经理,他说:“你可以用微电子产能。比如,第三世界的一个人,他有电话或者是智慧手机,但是却没电了,这是个很常见的事情。而你可以给他一双鞋子,可以通过走路就能产生能量并且可以充电,从而使那个人继续和外界保持联络。” 另一个创新会使那些难记的密码过时。很快,我们就会利用名为生物测定学的技术来进入邮箱或者银行账户。 “想象一下,事物能够辨别出你,当你走到取款机前,它看你一眼然后就说‘是的,是你本人。"”   :   The presence of students, ladies and teachers, everyone! I was prepared intervals of cloud today, in honor here entitled "Technology and Future" speech, I am very proud of both, but some unease. In recent years, we have seen our great motherland, the cause of the rapid development of technology, which allow me to a Chinese I feel very proud.

But I am willing to use a student"s perspective to the Imagine technology and the future.   From genetic engineering "is a live Princes" dream, nano-technology "- not washing your clothing," promises; From artificial intelligence "will give you a cute robot dog" warm, transgenic technology "let people grow mouse ears" Wonders. The new technology in the birth of a new technology that will let people wild with joy, because these new technologies is gradually improving our lives, let us learn more about ourselves. In the near term, China pleted its first SARS virus genome sequencing, SARS is now the world"s largest recognized the dangers of the disease, but why not other countries pleted first, and we just pleted the countries? Very simple, this illustrates that our country backward than others, worse than others, we look at the past, had just started a country"s reform and opening up to the current level of science and technology has lead a large country, our motherland experienced a number of ups and downs, how many difficulties and bumpy However, we still back all of the motherland, the motherland because we firmly believe that - not only technological change destiny, can change the future.   For our generation, the general feeling of the munity is a strong sense of petition, learning a foot down.

写一篇200字英语作文:新产品开发的重要性

The importance of new product development is a result of the necessity for developing new products if a business is to survive. In other words, new product development is tied to the ability of a business to remain competitive and also to the longevity of such a business. Any business that does not realize the importance of new product development will not last very long as a consequence of the fact that business is all about innovation and change, making it absolutely necessary for businesses to adapt to those changes in order to remain relevant. New product development may be geared toward the conceptualization of a new idea regarding a completely new line of products currently not in the market, or it could be aimed toward upgrading products that may be in the market already. Whatever the case, the development of new products is an essential part of the application of business strategies by companies.An illustration of the importance of new product development can be seen in the area of the transition from physical books to e-books. Some companies that built their reputation and even their entire company on the sale of physical books quickly folded due to the fact that they failed to realize the importance of new product development. These companies did not keep up with the changes in other areas of the market, such the innovations in technology that made it more convenient for people to download books onto a device rather than purchasing the physical book. Other companies that embraced new product development anticipated this change and not only made it possible for customers to download books from their Web sites, but also integrated this download with their own personal electronic readers, making it a complete package. This understanding of the importance of new product development has kept such companies relevant even in the face of constant innovations in technology and the tastes or preferences of customers.Another illustration of the importance of new product development is in the area of smart phones where some companies have managed to establish themselves as market leaders due to the fact that they always take the lead in new products. Such companies always come up with new products periodically, astutely gauging when their products in the market are already reaching the end of their product lifecycle. By replacing worn-out products with new ones, they manage to retain the interest of customers and to make their product and company relevant.

雅思英文官网范文

雅思官网范文文笔流畅,用词地道,摆脱千篇一律的中国模板范文,是真正能够帮你提分的好作文,那你知道雅思英文官网范文有哪些吗?下面是收集整理的一些雅思英文官网范文,大家一起来看看吧!雅思英文官网范文篇一:科技对日常交流的影响Nowadays the way many people interact with each other has changed because of technology.In what ways has technology affected the types of relationships that people make? Has this been a positive or negative development?范文:It is true that new technologies have had an influence on communication between people. Technology has affected relationships in various ways, and in my opinion there are both positive and negative effects.Technology has had an impact on relationships in business, education and social life. Firstly, telephones and the Internet allow business people in different countries to interact without ever meeting each other. Secondly, services like Skype create new possibilities for relationships between students and teachers. For example, a student can now take video lessons with a teacher in a different city or country. Finally, many people use social networks, like Facebook, to make new friends and find people who share common interests, and they interact through their computers rather than face to face.On the one hand, these developments can be extremely positive. Cooperation between people in different countries was much more difficult when communication was limited to written letters or telegrams. Nowadays, interactions by email, phone or video are almost as good as face-to-face meetings, and many of us benefit from these interactions, either in work or social contexts. On the other hand, the availability of new communication technologies can also have the result of isolating people and discouraging real interaction. For example, many young people choose to make friends online rather than mixing with their peers in the real world, and these u2018virtualu2019 relationships are a poor substitute for real friendships.In conclusion, technology has certainly revolutionised communication between people, but not all of the outcomes of this revolution have been positive.雅思英文官网范文篇二:政府是否应该出钱保护濒危语言题目:Several languages are in danger of extinction because they are spoken by very small numbers of people. Some people say that governments should spend public money on saving these languages, while others believe that would be a waste of money. Discuss both these views and give your opinion.范文:It is true that some minority languages may disappear in the near future. Although it can be argued that governments could save money by allowing this to happen, I believe that these languages should be protected and preserved.There are several reasons why saving minority languages could be seen as a waste of money. Firstly, if a language is only spoken by a small number of people, expensive education programmes will be needed to make sure that more people learn it, and the state will have to pay for facilities, teachers and marketing. This money might be better spent on other public services. Secondly, it would be much cheaper and more efficient for countries to have just one language. Governments could cut all kinds of costs related to communicating with each minority group.Despite the above arguments, I believe that governments should try to preserve languages that are less widely spoken. A language is much more than simply a means of communication; it has a vital connection with the cultural identity of the people who speak it. If a language disappears, a whole way of life will disappear with it, and we will lose the rich cultural diversity that makes societies more interesting. By spending money to protect minority languages, governments can also preserve traditions, customs and behaviours that are part of a countryu2019s history.In conclusion, it may save money in the short term if we allow minority languages to disappear, but in the long term this would have an extremely negative impact on our cultural heritage.雅思英文官网范文篇三:企业要承担的社会责任题目:As well as making money, businesses also have social responsibilities. To what extent do you agree or disagree?范文:Businesses have always sought to make a profit, but it is becoming increasingly common to hear people talk about the social obligations that companies have. I completely agree with the idea that businesses should do more for society than simply make money.On the one hand, I accept that businesses must make money in order to survive in a competitive world. It seems logical that the priority of any company should be to cover its running costs, such as employeesu2019 wages and payments for buildings and utilities. On top of these costs, companies also need to invest in improvements and innovations if they wish to remain successful. If a company is unable to pay its bills or meet the changing needs of customers, any concerns about social responsibilities become irrelevant. In other words, a company can only make a positive contribution to society if it is in good financial health.On the other hand, companies should not be run with the sole aim of maximising profit; they have a wider role to play in society. One social obligation that owners and managers have is to treat their employees well, rather than exploiting them. For example, they could pay a living wage to ensure that workers have a good quality of life. I also like the idea that businesses could use a proportion of their profits to support local charities, environmental projects or education initiatives. Finally, instead of trying to minimise their tax payments by using accounting loopholes, I believe that company bosses should be happy to contribute to society through the tax system.In conclusion, I believe that companies should place as much importance on their social responsibilities as they do on their financial objectives.雅思英文官网范文篇四:工作最重要的考虑因素是薪水题目:When choosing a job, the salary is the most important consideration. To what extent do you agree or disagree?范文:Many people choose their jobs based on the size of the salary offered. Personally, I disagree with the idea that money is the key consideration when deciding on a career, because I believe that other factors are equally important.On the one hand, I agree that money is necessary in order for people to meet their basic needs. For example, we all need money to pay for housing, food, bills, health care, and education. Most people consider it a priority to at least earn a salary that allows them to cover these needs and have a reasonable quality of life. If people chose their jobs based on enjoyment or other non-financial factors, they might find it difficult to support themselves. Artists and musicians, for instance, are known for choosing a career path that they love, but that does not always provide them with enough money to live comfortably and raise a family.Nevertheless, I believe that other considerations are just as important as what we earn in our jobs. Firstly, personal relationships and the atmosphere in a workplace are extremely important when choosing a job. Having a good manager or friendly colleagues, for example, can make a huge difference to workersu2019 levels of happiness and general quality of life. Secondly, many peopleu2019s feelings of job satisfaction come from their professional achievements, the skills they learn, and the position they reach, rather than the money they earn. Finally, some people choose a career because they want to help others and contribute something positive to society.In conclusion, while salaries certainly affect peopleu2019s choice of profession, I do not believe that money outweighs all other motivators.

虾青素,只有虾身上才会有吗?

那么有哪些食物能够有效补充虾青素呢?一、藻类多种藻类食物中的虾青素含量是较高的,特别是“雨生红球藻”,这也是鱼虾类含有虾青素的根源(鱼吃虾,虾吃藻类),一般说来,常被我们食用的且含有虾青素的藻类如海带、礁膜、紫菜、石花菜等,适当食用也有助于我们补充虾青素。二、虾蟹类由于虾、蟹等甲壳类海鲜产品主要是吃藻类、浮游生物等为主,所以各种虾蟹也含有一定量的虾青素,不过虾蟹壳中的虾青素占有更大比重,肉中虾青素含量相对较少。三、鱼类鱼是日常常见的食材之一,其种类较多,包含虾青素的鱼类有:鲍鱼、三文鱼、鱼籽、金枪鱼、鲤鱼、沙丁鱼等。其中三文鱼中的虾青素含量较为丰富,其中每公斤野生三文鱼肌肉中约含有5mg虾青素,是日常饮食补充虾青素的常见食品之一,但价格相对较贵。四、虾青素鸡蛋虾青素鸡蛋真正的虾青素鸡蛋,由于虾青素的富集,蛋黄会呈现橘红色或深红色,且虾青素含量越高,颜色越红。此外,一枚合格的“知雨生”虾青素鸡蛋需要经过20个星期的虾青素培育期,在120天的黄金产蛋期产出符合标准的虾青素鸡蛋,再通过层层筛选,使用10道工序4重检测淘汰40%不达标的产品,以保证每一枚虾青素鸡蛋的品质。现在大家了解了吧!想要更好地摄取虾青素,不是只有鱼类、虾蟹等类这些海鲜可供选择,关键它们虾青素含量并不高、而且价格也会更昂贵一些。因此,选择更加优惠的虾青素鸡蛋,可以更安全的摄入虾青素,且知雨生虾青素鸡蛋的高含量,仅需每天一枚就能满足人体对于虾青素的需求量,增强免疫能力,让您健康活力一整天,抗氧抗衰提免疫!

番茄红素详细资料大全

是植物中所含的一种天然色素。主要存在于茄科植物西红柿的成熟果实中。它是目前在自然界的植物中被发现的最强抗氧化剂之一。科学证明,人体内的单线态氧和氧自由基是侵害人体自身免疫系统的罪魁祸首。番茄红素清除自由基的功效远胜于其他类胡萝卜素和维生素E,其淬灭单线态氧速率常数是维生素E的100倍。它可以有效的防治因衰老,免疫力下降引起的各种疾病。因此,它受到世界各国专家的关注。 基本介绍 中文名 :番茄红素 英文名 :lycopene from tomato 别称 :ψ,ψ-胡萝卜素;茄红素;西红柿红素;蕃茄红素;番茄红素 化学式 :C40H56 分子量 :536.8726 CAS登录号 :502-65-8 EINECS登录号 :207-949-1 相关研究,物理性质,呈色能力,溶解性,英文别名,生物特性,合成途径,适用人群,药物试验,药理作用,生理功能,制备,套用, 相关研究 番茄红素(Lycopene)又称ψ—胡萝卜素,属于异戊二烯类化合物,是类胡萝卜素的一种。由于最早从番茄中分离制得,故称番茄红素。过去人们一直认为,只有那些具备β—紫罗酮环并能转化为维生素A的类胡萝卜素,如α—胡萝卜素、β—胡萝卜素等才与人类的营养和健康有关,而番茄红素因缺乏此结构,不具有维生素A的生理活性,故对此研究很少;然而,番茄红素具有优越的生理功能,它不仅具有抗癌抑癌的功效,而且对于预防心血管疾病、动脉硬化等各种成人病、增强人体免疫系统以及延缓衰老等都具有重要意义,是一种很有发展前途的新型功能性天然色素。 番茄 番茄红素(lycopene)是成熟番茄的主要色素,是一种不含氧的类胡萝卜素。1873年Hartsen首次从浆果薯蓣TamuscommunisL.中分离出这种红色晶体。 1910年,Willstaller和Escher在对番茄红素的研究中首次确定了其分子式为C 40 H 56 ,分子量为536.85。1913年Schunk发现这种物质和胡萝卜素的不同,将其首次命名为lycopene,使用至今,纯品为针状深红色晶体。1930年,Karrer等人提出,番茄红素是一种化学结构式中含有11个共扼双键及2个非共扼双键的非环状平面多不饱和脂肪烃,经过环化可形成β一胡萝卜素。天然存在的番茄红素都是全反式,但通过高温下的蒸煮、油炸等加工方式可使番茄红素由反式构型向顺式构型转变,而干燥番茄或干燥番茄渣中的顺式构型也会有部分的转变。研究还表明,番茄红素的顺式异构体与反式异构体的物理和化学性质有所不同,与反式异构体相比,番茄红素的顺式异构体的熔点低,摩尔消光系数小,极性强,不易结晶,更易溶解,而且在放置过程中可能会回复到全反式状态。 物理性质 由于番茄红素分子中有11个共扼双键及2个非共轭双键,使得番茄红素的稳定性比较差,在一定条件下可发生顺反异构化和氧化降解。番茄红素对氧化反应比较敏感,其溶液经日光照射12小时后,其中的番茄红素基本上损失殆尽。溶液中的Fe 3+ 和Cu 2+ 会对番茄红素的光氧化反应起催化作用,而其它金属离子如K+、Mg 2+ 、Ca 2+ 、Zn 2+ 等则对其影响不大,所以天然番茄红素在提取和套用过程中应尽量避免使用铁制和铜制容器。pH值对番茄红素也有影响,当用乙醇溶解番茄红素,并调制成pH值1~14,结果表明,番茄红素对酸不稳定,对碱则比较稳定,故番茄红素作为色素使用时并不适合于酸性饮料。由此可见,影响番茄红素稳定性的因素有氧、光、金属离子pH等,故番茄红素的提取、贮存、加工及分析都应该在对环境因素进行控制的条件下进行。 呈色能力 番茄红素作为一种天然红色素,如何保持其最强的着色力是至关重要的。番茄果实中的番茄红素有两种存在状态:其中大部分是以细长的、针状的结晶形式存在于有色体中,呈现明亮的红色。当番茄红素的结晶形成时,质体膜消失,色素结晶自由分散在原生质中,在显微镜下观察时,可以看到小粒状的有色体,说明了有色体所显现的颜色;另外一小部分(10%左右)则与蛋白质形成复合体存在于细胞中。番茄红素以不同的形态存在时具有不同的颜色和强度,而且会随着溶剂和介质的不同而呈现出不同的颜色。例如,溶解在石油醚中的番茄红素呈黄色,在二硫化碳中则呈红色。 溶解性 番茄红素是脂溶性色素,可溶于其他脂类和非极性溶剂中,不溶于水,难溶于强极性溶剂如甲醇、乙醇等,可溶于脂肪烃、芳香烃和氯代烃如乙烷、苯、氯仿等有机溶剂。番茄红素在各种溶剂中的溶解度随着温度的上升而增大,然而当样品越纯时,溶解越困难。结晶的番茄红素溶解缓慢,倾向于形成一种超饱和状态,虽然提高温度可加速其溶解,但冷却时可能会出现结晶,这时可利用超音波加速其溶解。纯的番茄红素虽然不溶于水,但当它与某些物质如蛋白质结合形成复合物时,则具有较高的溶解度。 英文别名 C.I. 75125; CI 75125; Lycopene Beadlet; LYCOSOURCE; LYCOPENE; JARCOPENE(TM); 4,4-CAROTENE; 2,6,10,14,19,23,27,31-OCTAMETHYL-DOTRIACONTA-2,6,8,10,12,14,16,18,20,22,24,26,30-TRIDECAENE; PSI,PSI-CAROTENE; Y,Y-CAROTENE; E 160d; (5cis,5"cis,9cis,13cis)-psi,psi-carotene 番茄红素 生物特性 具有抗氧化性 番茄红素通过物理和化学方式猝灭单线态氧或捕捉过氧化自由基。单线态氧是具有很强活性的氧自由基,具细胞毒性作用,以细胞膜、线粒体等部位对其最为敏感,能与细胞中多种生物大分子发生作用,通过与分子结合造成细胞膜系统的损伤;番茄红素能够接受不同电子激发态的能量,吸收光能并通过单线态—单线态能量转移过程使单线态氧的能量转移到番茄红素,生成基态氧分子和三重态番茄红素分子,三重态番茄红素通过与溶剂的一系列旋光和振动反应得到再生,并在此过程中将能量散发;类胡萝卜素的猝灭能力与其分子中所含有的共轭双键的数目有着密切的关系,番茄红素分子中有11个共轭双键,一个番茄红素分子可以清除数千个单线态氧,其猝灭单线态氧的速率常数较β-胡萝卜素高2倍。1990年Paolo等报导了类胡萝卜素和生育酚等30余种生物抗氧化剂猝灭单线态氧的作用,番茄红素是猝灭单线态氧最强的。 番茄红素还能通过与其他形式的活性氧的化学反应消除氧化自由基,如过氧化氢、亚硝酸根等氧化自由基,而氧化自由基能引起脂质过氧化形成多种产物,这些产物与人体老化、癌症发生、自身免疫病及贫血等疾病都有关系。 对细胞生长代谢起调控作用 通常细胞间隙之间有膜蛋白构成的通道,具有选择通透性,允许第二信使及生长调节物质通过,细胞之间通过细胞间隙连线通讯(GJIC)传输细胞群体内生长调控信号,调节细胞的正常增殖与分化。实验表明,番茄红素通过诱导细胞间连线,增强正常细胞之间的GJIC,控制细胞生长和诱导细胞分化来抑制肿瘤的增长。日本学者在大鼠肝组织上用萤光染料示踪技术研究番茄红素对GJIC的作用时发现,每天饲喂5mg/kgBW番茄红素,连续5d时,可以明显增强GJIC功能;同时,由于大多数肿瘤细胞的GJIC功能微弱或缺失,细胞发生转化后其GJIC功能降低或抑制,GJIC功能的抑制或被破坏被认为是促癌变阶段的重要机制。 可以调节胆固醇的代谢 番茄红素是一种低胆甾醇剂,它可抑制巨噬细胞3-羟基-3-甲基戊二酸单酰辅酶A,而它是一种胆固醇生物合成的限速酶。实验发现,在培养巨噬细胞的介质中加入番茄红素后,其胆固醇合成降低,同时番茄红素还增大巨噬细胞低密度脂蛋白(LDL)受体活性。实验还表明,人体3个月内每天补充60mg番茄红素,可减少14%的胞质LDL胆固醇浓度。 保健作用 番茄红素的上述生物学特性决定了它具有抗氧化、抑制突变、降低核酸损伤、减少心血管疾病及预防癌症等多种保健功能。 预防和抑制肿瘤的作用 番茄红素具有预防和抑制肿瘤作用,一方面是因为它的抗氧化作用;另一方面是番茄红素能够阻断组织细胞在外界诱变剂的作用下发生基因突变过程,这是肿瘤生成的重要机制之一。实验发现,番茄红素可影响乳腺、肺和子宫癌细胞周期的S阶段;番茄红素通过抑制细胞周期中Gl到S的转化阶段来影响细胞的生长;番茄红素通过可抑制LDL胆固醇的氧化和煎烤肉、鱼的褐色反应中产生的杂环胺类的形成,从而有效地抑制致癌物的产生及诱发肿瘤。研究表明,番茄红素对消化道癌、宫颈癌、乳腺癌、皮肤癌、膀胱癌等均有一定的抑制作用。 合成途径 番茄红素不仅分布在番茄中,还存在于木鳖果、西瓜、南瓜、李子、柿子、胡椒果、桃、木瓜、芒果、番石榴、葡萄、葡萄柚、红莓、云莓、柑橘等的果实,茶的叶片及萝卜、胡萝卜、芜菁甘蓝等的根部。番茄及其制品的番茄红素是西方膳食中的类胡萝卜素最主要的来源,人体从番茄中获得的番茄红素占总摄入量的80%以上。 除了植物中具有番茄红素等类胡萝卜素以外,一些微生物,如红法夫酵母,藻类,成团泛菌的某些种等都可以产生类胡萝卜素,特别是红发夫酵母和绿藻,的虾青素产量相对较高,酵母和大肠杆菌的遗传改造也使得本身不产类胡萝卜素的微生物可以进行这类物质的合成。番茄红素的生物合成途径: 番茄红素是类胡萝卜素的一种,人体自身不能合成类胡萝卜素,必须通过外界摄入;但类胡萝卜素在许多植物中含量较低,并且很难用化学方法合成,主要是通过生物合成方式完成。生物合成途径类胡萝卜素生 生物合成途径图 物合成可经由不同的途径,在真菌和植物细胞胞液/内质网上,由乙酰CoA经羟甲基戊二酰-CoA途径合成的。在细菌与植物质体中由磷酸甘油醛与丙酮酸经1-脱氧木酮糖-5-磷酸途径合成.形成的异戊烯基焦磷酸经多次缩合生成第一个类胡萝卜素八氢番茄红素,再经脱氢、环化、羟基化、环氧化等转变为其它类胡萝卜素。具体的生物合成途径如右图: 通过合成过程图可以很清楚的看出番茄红素、β胡萝卜素、玉米黄质(叶黄素)、角黄素等均为类胡萝卜素生物合成过程中间体,研究发现Astaxanthin(简称ASTA)虾青素为类胡萝卜素生物合成的终端形态。类胡萝卜素生物合成这些色素,主要是为了保护其种子中的不饱和脂肪酸,为下一代的繁衍储备能量。所以随着合成过程的不断推进,图中合成过程中的这些类胡萝卜素每一层次都比上一级的抗氧化活性强。 适用人群 番茄红素是类胡萝卜素的一种,由于最早从番茄中分离制得,故称“番茄红素”。番茄红素的抗氧化能力是胡萝卜素的3.2倍,是维生素E的100倍,人体无法制造番茄红素,需从膳食中摄取,吃一个生番茄,只能吸收0.05毫克的番茄红素。 前列腺疾病、肿瘤患者; 生活在环境污染严重地区者; 免疫力较低的中老年人群; 抗氧化,需延缓衰老者。 药物试验 哈佛大学医学院对47000名健康男性作了为期6年的研究,结果发现,每周摄取10份以上番茄制品的人,发生前列腺癌的机率降低45%,而服用4-7份的人只减少21%到34%。在美国底特律维纳州立大学从事癌症研究的土耳其医生奥末·库却克,用番茄素制成药用胶囊治疗前列腺癌病人,获得明显疗效。库却克对26名等候手术的前列腺癌症患者进行分组试验,一组服用他从西红柿中提取的番茄红素制成的胶囊,每天两次,每次15毫克;一组不服用这种胶囊。三周后他惊奇地发现,服用番茄素胶囊的病人,肿瘤明显缩小,有的几近消除。 研究人员对93例肺癌病人和102例无肿瘤的对照者进行研究,检测了血中番茄红素、alpha-胡萝卜素、beta-胡萝卜素和其它营养素的浓度,结果发现,两组人血液中各种营养素浓度相似,只有番茄红素不同,肺癌病人组织中番茄红素浓度显著低于对照组。在吸菸者中调查发现,番茄红素最低值组的发癌率约4倍于最高值组。此外,吸菸的肺癌病人体内番茄红素浓度最低。研究人员认为吸菸可使番茄红素在体内耗尽,或者使低浓度的番茄红素无法防止吸菸的致癌作用,从而发生肺癌。 Ben-Gurion大学的研究人员所做的最新研究发现,将番茄红素与其它抗氧化剂合理运用,可以促进女性 *** 的健康发育,并减少患乳腺癌的机会。美国依利诺斯大学的一项对比研究发现,体内番茄红素低的女性比体内番茄红素高的女性,宫颈癌的发病率要高出5倍以上。 哈佛大学及加拿大的研究人员发现,中年男性育前列腺组织中西红柿红素的含量逐渐降低,这个现象与男性前列腺肥大有非常重要的关联。并发现,有效补给适当剂量的番茄红素,可以帮助减缓前列腺肥大及发生癌变。食用大量番茄红素的人,患前列腺癌的风险比较低。已有研究数字表明,血液中番茄红素含量较高的男性比血液中番茄红素含量低的男性患此类癌症的机率大大减少。 印度新德里的医生发现番茄红素能够提高男子 *** 的质量,该项实验中,23岁到45岁的不育男性被要求每天口服番茄红素2次,每次六毫克。三个月后,再次检查他们的 *** 浓度、活性和形状,四分之三男性的 *** 活动能力和形态明显改善, *** 浓度明显提高。在实验结束时,有6人的太太怀孕,因此,此项实验结果具有实质上的统计意义。在健康男子的睾丸中,番茄红素含量很高,但在不育男子则较低。而口服番茄红素在治疗原因不明的男性不育症方面具有显著效果。 药理作用 番茄红素(Lycopene)是一种很强的抗氧化剂,具有极强的清除自由基的能力,对防治前列腺癌、肺癌、乳腺癌、子宫癌等有显著效果,有效抑制癌细胞的扩散和复制,还有预防心脑血管疾病、提高免疫力、保护细胞DNA免受自由基损害,防止细胞病变、突变、癌变;含强力抗氧化生物活物质,能促使细胞的生长和再生,美容袪皱,维持皮肤健康,延缓衰老等功效,有“植物黄金”之称,被誉为“21世纪保健品的新宠”。它是自然界中最强的抗氧化剂,其抗氧化作用是β-胡萝卜素的2倍,VE的100倍。在清除人体“万病之源”――自由基方面,番茄红素的作用比β-胡萝卜素更强大。2003年,美国《时代》杂志把番茄红素列在“对人类健康贡献最大的食品”之首,番茄红素也因此被称为“植物中的黄金”,番茄红素已在欧美、日本和中国港台地区被广泛接受。对防治前列腺疾病、前列腺癌、肺癌、胃癌、乳癌有奇效,有效抑制癌细胞的扩散和复制,被西方国家称为“植物黄金”。 预防和抑制癌症:最新研究成果表明,每天摄取30毫克番茄红素,可以达到预防前列腺癌、消化道癌以及膀胱癌等多种癌症的效果。人体无法合成番茄红素,必须从膳食中摄取,吃一个生番茄只能吸收0.05毫克的番茄红素。因此,在前列腺疾病的治疗中,补充番茄红素是必不可少的。 保护心血管:在动脉粥样硬化的发生和发展过程中,血管内膜中的脂蛋白氧化是一个关键因素。番茄红素在降低脂蛋白氧化方面发挥着重要作用。据报导,口服天然番茄红素,能使血清胆固醇降至5.20毫摩尔/升以下,番茄红素用于防治高胆固醇和高血脂症,可以减缓心血管疾病的发展。 抗紫外线辐射功能:番茄红素能对抗紫外线损伤。研究人员给10名健康人各补充28毫克β-胡萝卜素和2毫克番茄红素1-2个月,结果服用番茄红素人群紫外线引发红斑的面积减少,程度减轻。 抑制诱变作用:肿瘤生成的重要机制之一是组织细胞在外界诱变剂的作用下发生基因突变,而番茄红素能阻断这个过程,发挥抗癌作用。如地中海地区居民在煎烤鱼和肉的同时使用番茄酱,减少了烹调过程中杂胺等诱变剂的形成。所以虽然当地居民喜食易致癌的煎烤食物,但是宫颈癌、前列腺癌以及肝癌的发病率却很低。 延缓衰老、增强免疫力:番茄红素可以最有效地清除人体内的自由基,保持细胞正常代谢,预防衰老。番茄红素在体内通过消化道黏膜吸收进入血液和淋巴,分布到睾丸、肾上腺、前列腺、胰腺、 *** 、卵巢、肝、肺、结肠、皮肤以及各种黏膜组织,促进腺体分泌激素,从而使人体保持旺盛的精力;清除这些器官和组织中的自由基,保护它们免受伤害,增强机体免疫力。印度学者指出,番茄红素可令不育男子 *** 数量增加、活力增强,从而医治不育问题。 番茄红素可大大改善皮肤过敏症,消除因皮肤过敏而引起的皮肤干燥和瘙痒感,令人感觉轻松愉快。 番茄红素大量存在于体内各种黏膜组织,长期服用可以改善各种因体内黏膜组织破坏而引发的各种不适。如干咳、眼睛干涩,口腔溃疡,保护胃肠道黏膜组织等。 番茄红素还具有极强的解酒作用。酒精在人体内的代谢过程主要是氧化还原反应,会产生大量的自由基。平时服用番茄红素,可以增加酒量;喝酒前服用,解酒效果显著,可以减轻酒精对肝脏的损伤;而醉酒后服用,可以减轻头痛、呕吐等醉酒症状。 番茄红素还具有预防骨质疏松、降血压、减轻运动引起的哮喘等多种生理功能。 番茄红素没有任何副作用,非常适合长期保健服用。 番茄红素可帮助预防及改善前列腺增生、前列腺炎等泌尿系统疾病,并有助于提高男性 *** 质量,降低不育风险。一项来自美国哈佛大学的研究发现类胡萝卜素与前列腺癌有一定的关系。在类胡萝卜素的研究中,只有番茄红素具有明确的保护作用。男性每天在饮食中服用最大剂量的番茄红素(每天6.5毫克以上)与服用最少者相比,可以使前列腺癌发生的危险减少21%。 番茄红素大量存在与番茄中,番茄红素可消除令男性不育的有害化学物。因此多喝番茄汤可以有效增强男性的生育能力。 英国科学家发现,令番茄汤呈现红色的茄红素,或许能把男性体内的 *** 强化成超级 *** ,科学家由此推断男士只要每日饮一碗番茄汤,将能大大增强生育能力。 英国朴茨茅斯大学生化科学部的5名泌尿科专家随机挑选了平均年龄在42岁左右的精壮男士,要求他们在两周内每天饮用一碗番茄汤,其间收集他们的 *** 样本。 结果发现, *** 内可消除令男性不育的有害化学物自由基的茄红素水平显著增加,升幅介乎7%到12%。 生理功能 有助于延缓衰老; 有助于增强抗辐射能力; 有助于调节血脂; 对男性不育有改善作用; 有助于促进女性 *** 的健康发育。 预防和抑制肿瘤的作用。 分布 番茄红素分布于木鳖果、番茄、西瓜、南瓜、李、柿、胡椒果、桃、木瓜、芒果、番石榴、葡萄、葡萄柚、红莓、云莓、柑桔等果实和萝卜、胡萝卜、芜箐、甘蓝等的根部。各种水果中番茄红素含量如下(每100g果肉): 木鳖果 木鳖果:155~305毫克 西红柿:0.2~20毫克 番石榴:5.23~5.50毫克(粉红色) 番木瓜:0.11~5.3毫克 葡萄柚:0.35~3.36毫克(粉红色) 胡萝卜:0.65~0.78毫克 南瓜:0.38~0.46毫克 红薯:0.02~0.11毫克 杏子:0.01~0.05毫克 番茄和番茄制品中的番茄红素,是西方膳食中类胡萝卜素最主要的来源,也是人体血清中含量较高的。人们从番茄中获得的番茄红素约占其总摄入量的80%以上。传统西红柿中的番茄红素含量相当少,并且大量存在于西红柿籽周围的类脂物中,喝西红柿汁或吃新鲜西红柿通常意味着番茄红素只是通过人体而很少被吸收。为了生产具有保健及治疗价值的番茄红素营养制剂,国内外许多大的保健品公司及制药公司,开发出含番茄红素的软胶囊,以利于补充人体中的番茄红素。木鳖果中高含量的天然脂质的番茄红素更为宝贵! 番茄红素广泛存在于人体的各种器官和组织中。主要分布在人的血液、肾上腺、肝脏、睾丸、前列腺、乳腺、卵巢、子宫、消化道等器官中,其中血液、肾上腺、肝脏、睾丸等含有较多的番茄红素。番茄红素具有非常优越的生理功能其清除单线态氧的速率常数是常用抗氧化剂维生素E的100倍,是β—胡萝卜素的两倍之多。番茄红素是抗氧化性最强的类胡萝卜素。番茄红素能有效的预防前列腺癌,对子宫癌、肺癌细胞的抑制作用显著高于β—胡萝卜素、α—胡萝卜素。而且,人体内番茄红素的含量与人的寿命相关。番茄红素还具有抑制低密度脂肪蛋白的氧化和抗紫外线作用。番茄红素是很有前途的一种功能性天然色素。 吃番茄要注意:1番茄不能和抗凝血的药物,如肝素等一起服用,因为番茄中含有一种维生素叫维生素K,它是一种促进凝血的物质,与抗凝血药物一起服用,就会大大削减药效,对疾病的治疗不利。2服用新斯的明或加兰他敏等抗过敏的药物时不要食用番茄,因为番茄中的番茄旃会对这些药物产生影响,引发不良反应。3未成熟的青番茄不要食用,因为青番茄中的番茄碱含量较高,食用后可能出现恶心、呕吐、胃痛等不适症状,一次食用过多,还可能出现食物中毒,因此一定要注意。 制备 1.1浸提法: 番茄红素不溶于水,难溶于甲醇、乙醇,可溶於乙醚、石油醚、己烷、丙酮,易溶于氯仿、苯、二硫化碳等有机溶剂。利用这一性质,可利用亲油性有机溶剂浸提番茄红素。一般工艺为:番茄皮进行干燥后用有机溶剂提取;过滤后滤渣继续用有机溶剂进行二次浸提,滤液部分浓缩后成为粗产品,精制可得番茄红素。 在提取过程中,为了分离叶黄素与番茄红素,一般先用有机溶剂洗去叶黄素,再加另一有机溶剂提取番茄红素,常常使用不止一种有机溶剂,给最后的精制带来一定麻烦。为此又有人对此工艺进行改进。改进一为利用皂化反应使晶体析出,其工艺为:将番茄皮或制品进行干燥,加入一定量的植物油,研磨成细小颗粒,加入丙二醇、氢氧化钾、水使之发生皂化反应;加水并静止搁置使晶体析出。这一过程关键是皂化反应时控制提取物、丙二醇、氢氧化钾与水的比例在4~5:3~4:1:1皂化反应原料添加顺序灵活,最佳为将碱液缓缓加入番茄红素油溶脂与丙二醇的均相液中,以保证晶粒的最好析出。 改进二为利用有机溶剂在不同浓度、温度下对不同物质的溶解度不同,采用单一溶剂二次萃取。工艺为:番茄及制品进行洗涤,破碎等预处理;加入72%的酒精加热沸腾15min,过滤后的不溶物继续用94%的酒精在72℃下浸提3~4次每次10min;将滤液合并,在10℃下静止2~12h晶体析出。该工艺以含水20%~30%(最好28%)的酒精进行预处理即可洗脱极性物质如叶黄素、胡萝卜素及农药,又可避免溶解番茄红素。 1.2超临界萃取法: 番茄红素(加工) 具有工艺简单,能耗低,萃取剂便宜、无毒、易回收,可低温处理,适于番茄红素等热敏性成分的优点。 Enzo等研究了温度在40℃~80℃,压力在1.8X105~2.88X105Pa,操作参数对β胡萝卜素与番茄红素分离的影响,日本一专利报导了超临界流体萃取精制番茄红素。将粗番茄红色粉末和己烷(1:2)放入抽提罐,形成均质混合系,使原料中的色素从己烷中溶出,在35℃~50℃300kg/cm2的条件下,接触超临界CO2;,用减压法进行色素回收,在分离罐中得到精制番茄红素(含量13.7%)。孙庆杰等报导了此方面的研究,并建立了一套实验装置。该装置可取得90%以上的番茄红素,经超临界萃取的番茄红素无异味,无溶剂残留。 1.3 酶反应法: 日本一些专利”"介绍了利用番茄皮自身酶反应来提取或制备番茄红素的方法。在微碱条件下(pH=7.5~9),使番茄皮中的果胶酶和纤维素酶反应,分解果胶和纤维素,使得番茄红素的蛋白质复合物从细胞中溶出。所得色素为水分散性色素。 1.4 生物及化学合成法: 由于番茄红素在天然产物中的含量较低,提取代价较高,各国学者又相继在生物及化学合成领域进行了研究,并取得了一些突破。由丝状真菌三孢布拉霉Blakesleatrispora生物合成β胡萝卜素的过程中,通过pH控制环化即可合成番茄红素。Gavilou等在三孢布拉霉的生长介质中加入工业番茄废水,发现抑制了β—胡萝卜素的生产并 *** 番茄红素的合成。Obata等通过对蜂房芽孢杆菌DC—1在6~7klx光照下培养生产番茄红素。Mat *** ural等开发了能积聚番茄红素螺旋藻的生产方法,通过发酵并在培养基中加入尼古丁200~500mmol/L生产番茄红素,该方法成本较低。 生命红番茄红素制作厂 罗氏公司所采用的合成番茄红素工艺是由三苯基(3,7,1l—三甲基—2,4,6,10—十二四烯基)—氯化磷与2,7—二甲基-2,4,6—辛三烯二醛用甲醇钠甲醇在2—丙醇中进行Wittig烯化反应,制得番茄红素,收率65%。此外,Wegne等也完成了由三苯基(3,7,11—三甲基—2,4,6,10—十二四烯基)—甲磺化磷与2,7—二甲基—2,4,6—辛三烯二醛经Wittig烯化反应得到番茄红素的工艺开发,并在欧洲提出专利申请,1999年10月获批准。 1.5 其他方法: 在各国学者的不断努力下,又开发出许多高科技的生产技术。日本Kirin Brewerry公司采用代谢工程技术,即通过DNA重组技术改变细胞的代谢系统生产番茄红素。Kajiwara等从产生虾黄素的酵母Pharffi"arhosozyma和雨生红球藻中分离出cDNA编码异戊烯焦磷酸酯(IPP)异构酶,将编码IPP异构酶cDNA转入E.codi菌株JMl01能增加番茄红素的产量3.6~4.5倍。相信随着科技的发展和研究的深入这些技术会更加完善和成熟。 套用 番茄红素的套用: 美国、日本已相继生产出以番茄红素为主要活性成分的药品,其主要作用是降低血压、治疗高胆固醇、高血脂、降低癌细胞的活性等。美国、法国有用于预防前列腺癌的番茄红素产品。以色列、澳大利亚有用于防止紫外线灼伤,保护皮肤、健肤养颜的产品。还有用于番茄红素功能性产品。用于类胡萝卜素复合产品,主要与α一胡萝卜素、β一胡萝卜素和叶黄素合用于功能性食品。这些产品一般为胶囊或液体 。 番茄红素作为生理活性物质受光、热、氧气、pH等因素影响,极易发生氧化和分解,从而失去对人体的生理活性功能和营养价值,甚至引起机体癌变等严重后果。采用微胶囊技术对番茄红素进行包埋处理,可提高它在功能性产品中的可用性,并促进其生理功能的发挥。因此,采用微胶囊技术对番茄红素进行包埋是亟待研究的核心技术 。
