Allicin itself is not very stable, it will degrade slowly when placed, and will be destroyed quickly when cooking. It is used as an antioxidant in medicine. The main anticancer component in garlic is diallyl sulfide (DAS) and its homologues. It has a wide range of cancer prevention and anti-cancer, such as human NPC csn-3 and csn-7, gastric cancer, esophageal cancer, oral cancer, lung cancer, skin cancer, etc. Anti cancer and anti-cancer mechanism: anti DNA mutation or mutation, immune regulation, anti-oxidation and induction of apoptosis (apoptosis).
4. Functional food from oil crops
Oil crops have been playing a very important role in human diet. In the early days, people focused on the rich oil and protein in these plants. In recent years, studies have found that many trace components in oil crops, such as phospholipids, phytosterols, vitamin E, carotenoids and quinones, have important health care effects on human health. These research results make many oil crops, such as soybean, sesame, flax and olive, become hot spots of functional food research and development. Soybean isoflavones and Soyasaponin are the most attractive bioactive substances in the study of soybean. In recent years, a large number of studies at home and abroad have shown that soybean isoflavone, as a kind of phytoestrogen, has a very significant activity in anti-tumor, prevention of osteoporosis, cardiovascular and cerebrovascular diseases, delay of menopausal symptoms of women, etc., making it a favorite of functional food development.
Efficacy of plant functional food
(1) Anti-aging or antioxidant functional foods;
Although the sources of natural antioxidants are different, and the chemical structures of the substances with antioxidative activities in natural products are different, the research shows that most of these active substances belong to several categories, and each kind of compound has similar structure and properties, which can show certain antioxidative activities.
Classification: polysaccharides, flavonoids, polyphenols, alkaloids, saponins, vitamins
(2) Plant functional food for cancer prevention;
The relationship between the preventive effect (especially the curative effect) of cancer and the structure of the functional factors that play the role of chemical prevention is a very complex problem involving biochemistry, pharmacology, pharmacology, prevention and clinical medicine, organic chemistry, molecular biology and other disciplines. Some functional factors with better effect of cancer prevention have very distinct structural characteristics. Polyhydroxystilbene (stilbene) compounds. There are many methoxy groups around (or on the substituted ring) flavonoids. (3) Plant functional food for cardiovascular disease prevention
The occurrence of cardiovascular (cerebrovascular) disease is a rather complex problem, which involves bioengineering, protein chemistry, mutagenesis, enzymology, pathology and molecular biology. In recent 20 years, a lot of research work has been done on the role of LDL and VLDL in atherosclerotic atherosclerosis, which makes people have a deeper understanding of the formation of cardiovascular disease, but there are still many problems that are not clear. In the later stage, when high blood pressure and diabetes become entangled, it is difficult for phytochemicals to have the power to return to the sky. Because of this, most of the current research work on the prevention and treatment of heart (brain) blood vessels also focuses on the initial stage.
