Lycopene is a type of carotene that exists in plant foods and is also a kind of red
Food Coloring. Crimson -like crystals, soluble in chlorine, benzene, and grease without soluble in water. It is unstable to light and oxygen, and the iron becomes brown. Molecular C40H56, relative molecular mass 536.85. There are 11 common bonds and 2 non -commonly -dual bonds on the molecular structure, forming a straight -chain hydrocarbon compound. There is no physiological activity of vitamin A, but it has a strong antioxidant function. The content of mature red plants is high in fruits, especially with tomato, carrot, watermelon, papaya and guava. The
tomato lycopene powder can be used as pigmentation in food processing and is often used as raw materials for antioxidant health foods.
Lycopene (Lycopene) exists in fruits such as tomato, tomato products, watermelon, grapefruit, etc. It is the main pigment in mature tomatoes and one of the common carotene. In 1989, Mascio found that lycopene's hamstormation of single -wire oxygen in all carotene was the highest. Subsequently, the research on the function of lycopene became a hot spot. The research content involved the absorption and metabolism of lycopene, the risk of lycopene reduced the risks of various tumors and cardiovascular diseases such as prostate cancer, and the extract of lycopene extraction And measurement method, etc. At present,
tomato lycopene extract is not only widely used as natural pigments, but also more and more used in functional foods, medicines and cosmetics.
The lycopene absorption rate is higher than α-carotene and β-carotene, but it is also affected by many factors. The cashmere configuration is easier to absorb more than the transient configuration lycopene. Most of the natural existence lycopene is a full anti -type configuration, and most of the human tissues are cubs (> 50%), and the proportion of lycopene cubs in the body does not follow the food. The differences in lycopene configuration are changed. It is currently believed that the transliteration of lycopene in the gastrointestinal tract before absorbing is a cosmetic structure. The protein-carotene complex in food, a large amount of soluble dietary fiber (if glue), cholesterol and resin, and lack of iron, zinc and protein, and intestinal diseases may interfere with lycopene absorption. Thermal processing can transform the transforming part of the natural lycopene into a cashmere structure, and the fat in the food matrix can promote the release of lycopene. The lycopene after adding oil heat treatment is easier to absorb as unprocessed lycopene.
Different human experiments reports that the semi -reduction period of lycopene can be between 2 to 3 days and 10 to 33 days. Emeliangina nutrition can generally be judged by serum lycopene concentration. Adult serum lycopene content in American adults is mostly between 0.42 and 0.47 μmol/L. The basic data of the system reported that the 69 -year -old adult serum samples aged 30 to 92 in a community in Shanghai were reported. The average content of lycopene was about 0.32 μg/ml (about 0.59 μmol/L).
Caimantoine has a long -chain polymaturated olefin molecular structure that enables it to have a strong elimination of free radicals and antioxidant capabilities. At present, the research on its biological effects is mainly concentrated in the aspects of antioxidant, reducing the risk of cardiovascular disease, reducing genetic injuries and inhibiting tumor development.
The Funtion of Lycopene
1. Enhance the body's oxidation stress ability and anti -inflammatory effect
Oxidation damage is considered one of the main causes of increasing incidence of cancer and cardiovascular and cerebrovascular diseases. The in vitro antioxidant capacity of
tomato extracts lycopene has been confirmed by many experiments. The ability of lycopene to quake single-wire oxygen is more than 2 times that of the current commonly used antioxidant β-carotene, which is 100 times that of vitamin E.
2. Protective cardiovascular and cerebral blood vessels
Caimotina can deepen blood vessel waste, regulate plasma cholesterol concentration, protect low -density lipoprotein (LDL) without oxidation, can also repair and perfect cells that have been oxidized, promote the formation of intermedial glue, and enhance blood vessel flexibility. A survey research shows that serum lycopene concentration is negatively related to the incidence of cerebral infarction and cerebral hemorrhage. Studies of lycopene anti-domestic rabbit atherosclerosis show that lycopene can effectively reduce the level of total rabbit serum (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C), which The effect is equivalent to Flosin sodium. Another study has shown that lycopene has a protective effect on local brain ischemia. It mainly suppresses neuroplastic cell activity through antioxidant and clear free radicals, and reduces the area of brain irrigation injury.
3. Protect the skin
Caatocyl also has the functions of reducing skin radiation or ultraviolet (UV) damage. When UV is irradiated with the skin, the lycopene in the skin is combined with the free radicals produced by UV to protect the skin tissue from destruction. Compared with the skin that does not illuminate UV, lycopene decreases by 31%to 46%. constant. Studies have shown that foods rich in lycopene can fight UVs and avoid UV irradiation to produce erythema. Caimide can also quench the free radicals in the epidermal cells, which has a significant fading effect on the elderly's pigmentation.
4. Enhance immunity
Emerauline can activate immune cells, protect phagocytocytes from its own oxidation damage, promote the proliferation of T and B lymphocytes, stimulate the function of T cells, and promote the production of certain pantonin and inhibit inflammation media. Studies have found that taking lycopene capsules in the middle dose can improve the immunity of the human body and reduce the damage to the body's immunity to the body.
