番茄红素及其生理功能 总被引:5,自引:0,他引:5
番茄红素是一种天然类胡萝卜素,现国外已有企业将其从番茄中提取出来作为功能性添加物或者药物中的功能性成分来使用。有关其生理功能的研究正成为一个热点,对番茄红素在人体内的吸收,转运方式,各组织中的分布及生理功能,应用现状等的研究概况做一简要介绍。 相似文献

番茄红素最早是Millowdet在1875年从番茄中获得的,当时命名为Solanorubin。1903年,Schunck发现番茄中的红色素的吸收光谱与胡萝卜素相同,将这种红色素命名为Lycopene。番茄红素是类胡萝卜素的一种,是由11个共轭及2个非共轭碳-碳双键组成得直链型碳氢化合物,分子式为C40H56。 相似文献

Lycopene is a carotenoid naturally present in tomatoes. Among the carotenoids, lycopene is a major component found in the serum. Several studies including animal, cell culture, and epidemiological investigations have demonstrated that dietary lycopene has the ability or potential to reduce the risk of chronic diseases such as cancer and coronary heart disease. The role of lycopene in human health is thought to be its role as an antioxidant, but recent studies have demonstrated that other mechanisms are responsible for its beneficial properties. These include intercellular gap junction communication, hormonal and immune system modulation, and metabolic pathways. This article summarizes the background information about lycopene and presents the most current knowledge with respect to its role in human health, stability, toxicity, and extraction methods. 相似文献

Lycopene cis-isomers have shown to be more bioavailable and bioactive than the naturally occurring all-trans-isomer. During food processing, lycopene undergoes geometrical isomerization, increasing the proportion of cis-isomers. However, lycopene tends to retro-isomerize during food storage. Because the stability, bioavailability, and distribution of lycopene isomers are physiochemical characteristics critical for health benefits, it is essential to preserve these properties in food products containing lycopene isomers. The objective of this article is to review thermal and nonthermal technologies available for lycopene geometrical isomerization with a focus on the stability, bioavailability, and bioactivity of lycopene isomers. 相似文献
