[27] A 2010 review concluded that research has been insufficient to establish whether lycopene consumption affects human health. [23] Cara cara navel, and other citrus fruit, such as pink grapefruit, also contain lycopene. [7], Lycopene is a symmetrical tetraterpene assembled from eight isoprene units. The bioavailability of cis-isomers in food is higher than that of all-trans isomers. Based on the above, FDA concludes that there is no credible evidence supporting a relationship between lycopene consumption, either as a food ingredient, a component of food, or as a dietary supplement, and any of these cancers. As per a 2016 study , the presence of this compound will stunt the growth of certain cancerous tumors, or even reverse the growth and help induce apoptosis . Tomato skins and their mixtures with seeds were submitted to supercritical CO2 extraction using a flow apparatus at pressures of 250 and 300 bar and temperatures of 60 and 80 °C. A high level of lycopene reduces the level of oxidized components of DNA, it acts as a kind of prevention of cancer of the stomach and prostate. Quantitative growth experiments conducted in dark, semiaerobic conditions, using a growth medium for high cell density and high intracellular membrane levels, which are suitable for the conventional industrial production in the absence of light, yielded lycopene at up to 2 mg/g (dry weight) of cells or up to 15 mg/liter of culture. [4] Intestinal absorption of lycopene is enhanced by the presence of fat and by cooking. 49. Lycopene bioavailability in processed tomato products is higher than in unprocessed fresh tomatoes. The two terminal isoprene groups of lycopene can be cyclized to produce beta-carotene, which can then be transformed into a wide variety of xanthophylls.[4]. CopyCopied, CSID:394156, http://www.chemspider.com/Chemical-Structure.394156.html (accessed 20:03, Jan 7, 2021) Lycopene is an open chain unsaturated carotenoid that gives tomatoes, guava, rose hip, watermelon and pink grapefruit its red color. Lycopene diet reduces the risk of developing a number of chronic diseases, both the cardiovascular system and internal organs. Lycopene is a key intermediate in the biosynthesis of carotenoids, such as beta-carotene, and xanthophylls.

Our previous studies showed that in vitro enrichment of low-density lipoprotein (LDL) with β-carotene protected it from cell-mediated oxidation. The supercritical fluid process is being … Tomato and tomato products are rich sources of lycopene. However, unlike other carotenoids, lycopene levels in serum or tissues do not correlate well with overall intake of fruits and vegetables. Formulated products containing more than just tomatoes can also be analyzed using this procedure but only with care. RESULTS: The lipid profile showed lycopene and astaxanthin decreased total cholesterol, low-density lipoprotein-cholesterol (LDL-C), very LDL-C, and triglycerides and increased high-density lipoprotein-cholesterol level significantly (P < 0.05) compared to the control but less than atorvastatin. Lycopene may affect the immune system, the nervous system, sensitivity to sunlight, or drugs used for stomach ailments. Studies show that lycopene intake is significantly associated with lower risk of lung, colon and stomach carcinogenesis. [14], A 2017 review concluded that tomato products and lycopene supplementation had small positive effects on cardiovascular risk factors, such as elevated blood lipids and blood pressure. Lycopene more sensitive to the oxidation reaction, the solution after 12 hours by sunlight, which basically wiped out of lycopene. Additional lycopene benefits are that it also reduces low density lipoprotein (LDL) oxidation and reduces cholestoral levels in the blood. [33] The US Food and Drug Administration (FDA), in rejecting manufacturers' requests in 2005 to allow "qualified labeling" for lycopene and the reduction of various cancer risks, provided a conclusion that remains in effect as of 2017[update]: "...no studies provided information about whether lycopene intake may reduce the risk of any of the specific forms of cancer. [10], Dispersed lycopene molecules can be encapsulated into carbon nanotubes enhancing their optical properties. Supplementation with tomato juice increases plasma lycopene but does not alter susceptibility to oxidation of low-density lipoproteins from renal transplant recipients. Through several desaturation steps, phytoene is converted into lycopene. Tomato lycopene and low density lipoprotein oxidation: a human dietary intervention study.
