There is a white translucent material exist in the shrimp shells which has a scientific name "chitin". It is a natural polysaccharide polymer. Chitin by chemical acetyl-off after a "chitosan" (scientific name "deacetylation of chitin"). Over the past few decades, scholars abroad nutritional health effects of chitosan have done a lot of research and found that it has many health benefits. U.S. FDA as early as 10 years ago formally approved as a GRAS grade chitosan (ie, recognized as safe) natural raw materials, can be used for health food or food and beverage products. Since then, the chitosan type of health food in the U.S. and European markets will be popular.
Now, Japan has become the world's largest consumer of chitosan, followed by the United States and Europe. Currently, the global consumption of large amount of chitosan was about 4 to 5 million tons, which is most used in the production of health food. China is the world's largest producer of chitin and chitosan, chitin and chitosan its domestic total annual output of 30,000 tons, resveratrol the vast majority of products for export, the domestic market is minimal. This is mainly because China's domestic consumers know little about the health effects of chitosan, which is China has not yet formed chitosan type of health food consumption boom of the main reasons.
Because chitosan non-toxic to humans, can add in any proportion of food, so, not only a variety of chitosan in the foreign health food, and even chocolate, candy, cookies, cakes and other public food and beverage products are add a certain amount of chitosan component, in order to improve their nutritional and extend its shelf life (because of chitosan to inhibit mold growth effect). It is said that in Japan, even the soy sauce and bean paste and other spices also add the mass of chitosan (chitosan is not only due to lipid-lowering effect, but also improve the soy sauce, miso taste and to prevent mold product). It is understood that most foreign markets to develop health food chitosan as all kinds of "slim pill" products, in addition to the main component of chitosan, but also add a ephedrine, sheath core flowers, white kidney beans, chia seed melons, beans, children plastic, such as Garcinia Cambodia has a natural weight loss ingredients of plant extracts. In short, the chitosan products on foreign markets has become a popular health food.
Although China is the world's largest producer of chitosan, chitosan, plant extracts but the domestic health food market has not fully open, so although there are few manufacturers in the production of chitosan type of health products, but in general the market was on hiatus. In fact, as early as 30 years ago, the chitosan on the international nutrition circles as the "sixth nutrients the human body" (ranked in sugar, fat, protein, vitamins, minerals after). Therefore, the proposed China chitosan type of health food manufacturers to increase product promotion efforts to promote domestic consumers can understand the multiple health effects of chitosan and chitosan in the domestic food industry bigger and stronger type of health .
There are many health effects of chitosan. Help to reduce the weight test confirmed that chitosan has a great role in fat absorption, it is in the digestive tract can absorb the equivalent of 4 to 10 times its own weight of oil, and the expansion of the formation of a body of material, and ultimately excreted along with feces. In general, obese people taking chitosan capsules in successive weeks at least reduce the 8% of body weight. Blood pressure lowering effect of chitosan mainly by blocking sodium ion in the food absorbed into the blood and thus play an effective role in lowering blood pressure. Because the positively charged chitosan molecules, it can be used with the negatively charged metal ions such as sodium ions combine to form complex, and ultimately excreted. Chitosan has excellent prevention of vaginal mold and other fungi inhibiting the role of microbial growth, preventing its Candida albicans vaginitis particularly useful. Improve renal function tests were done abroad, pharmaceutical raw materials confirmed that taking a day for renal dialysis 4g chitosan can improve renal function. Prevention of colorectal cancer because chitosan has good adsorption of organic material effect, it is after it enters the intestinal absorption in the intestines out with food into the intestine with a variety of organic compounds, it can prevent colorectal cancer. Anti-inflammatory role in the international market, selling "glucosamine hydrochloride" is one of chitosan derivatives, it has excellent anti-osteoarthritis and degenerative joint disease age-effect. In addition, chitosan is also equivalent to a high-quality dietary fiber, it has anti-constipation effect; can promote calcium absorption; lower body LDL (bad cholesterol) ratio, and can also increase HDL (good cholesterol) of proportion.
