Rich mulberry leaf resources in China

Mulberry is a deciduous shrub or tree species of mulberry family It is also an ancient economic crop with a very long history It is internationally recognized that sericulture started in China For example, the book of songs has recorded the poems of Chinese farmers' sericulture By the 18th century, China had become the world's largest sericulture country, silk producing and exporting country The mulberry area once reached tens of millions of mu, and it was mainly concentrated in the south of the Yangtze River Therefore, the south of the Yangtze River has become one of the richest regions in China Mulberry leaf can not only be used as the ration of silkworm baby, but also as a kind of Chinese medicine For example, the earliest Chinese medicine classic Shennong materia medica has included mulberry leaf items Mulberry can be used as medicine all over the body, such as mulberry leaves, mulberry, mulberry branches (mulberry branches) and mulberry root bark (Mulberry white bark) are commonly used medicine It is reported that as early as 1992, the Ministry of health of China has listed mulberry leaves as one of the dual-purpose Chinese herbal medicines According to modern research, mulberry leaves are rich in nutrients and active ingredients The protein content of dry mulberry leaves is 8-12g per hectare In addition, mulberry leaves also contain 17 amino acids, vitamin E, B1, B2, B5, B12 and β - carotene Mulberry leaves also contain isoquercetin and other flavonoids, Achyranthes bidentata sterol, adenine, GABA (gamma aminobutyric acid) and choline and other active ingredients According to Japanese scholars, l-deoxynojirimycin (DNJ) is the most active ingredient in mulberry leaves It is a powerful hypoglycemic substance and can effectively reduce postprandial hyperglycemia Among all kinds of plant leaves, mulberry leaf is one of the leaves with the most comprehensive functions of nutrition and health care To some extent, the value of mulberry leaf as a nutritional and health product is even more than that of ginkgo leaf Mulberry leaves are generally used in the treatment of "lung heat" or wind heat diseases (such as the classic Chinese medicine formula "sangjuyin") Japanese scholars believe that mulberry leaf can be used for lowering blood fat, blood pressure, blood sugar, inhibiting cancer cells, regulating adrenaline, enhancing body resistance, anti stress and sleeping According to the Japanese Journal of food science, Japanese researchers processed the fresh mulberry leaves into micro powder and fed them to the experimental animal model of hyperglycemia The results showed that the blood sugar of rats basically returned to the normal range after one month of continuous consumption This result immediately attracted the attention of the health food industry in Europe and the United States, because diabetes has become one of the high incidence in developed countries It is reported that there are about 136 million people suffering from diabetes in the world Therefore, the market development space of mulberry leaf hypoglycemic health care products is very huge Why does mulberry leaf have such excellent hypoglycemic effect? According to the analysis, this is because the fresh mulberry leaves contain a natural active substance, DNJ, which can inhibit the intestinal absorption of glucose, and it can block the absorption of glucose in the intestinal tract (similar to the role of "α glucosidase inhibitor" like "betanpine", a popular hypoglycemic drug on the international market) Secondly, some scholars speculate that the crude polysaccharide in mulberry leaves also has synergistic hypoglycemic effect In a word, the hypoglycemic effect of mulberry leaves has been recognized by the international nutrition circle A large number of studies have confirmed that mulberry leaves are harmless to human beings and animals, even if they are eaten for a long time American scholars reported that taking a little mulberry leaf powder capsule often can also eliminate the "General belly", so it has a significant weight loss effect This is good news for the overweight Japan is the first developed country in the world to research and develop mulberry leaf health food, which has been listed in the early 1990s At present, it is said that there are dozens of mulberry leaf health food in the Japanese market, with an annual output value of several billion yen The Japanese market has mulberry leaf tea, mulberry leaf - job's tears tea, mulberry leaf - persimmon leaf tea, mulberry leaf oral liquid, mulberry leaf sushi, mulberry leaf biscuit, mulberry leaf cake and other nutritional health food In the U.S market, there are mulberry leaf tea, mulberry oral liquid and other health products containing mulberry leaf extract It is reported that Japan needs about 200000 tons of feed grade mulberry leaves and 50000 tons of medicinal / health food mulberry leaves annually However, due to Japan's small land area, most of the mulberry leaves needed are imported from China, Vietnam, Laos and other Southeast Asian countries, and the annual import volume of mulberry leaves is very amazing Since the 1990s, the sales volume of mulberry leaf health tea beverage market in the United States has increased year by year At present, the annual sales of mulberry leaf health tea and mulberry health juice products in the U.S and European markets are estimated to be millions of dollars With the hot sale of health food such as mulberry leaf tea in the international market, China's mulberry leaf health food industry has started For example, a biological company in Beijing is a professional company specialized in mulberry planting, mulberry leaf export and mulberry leaf health food processing The company has many kinds of health food, such as feed grade mulberry, tea mulberry, silkworm mulberry, fruit mulberry and so on In recent years, the development speed of mulberry leaf health care products in China has begun to accelerate It is reported that there are many kinds of health care products such as mulberry leaf tea, mulberry leaf chewing tablets, mulberry leaf dry powder and mulberry leaf nutrients in the market of China Due to insufficient publicity, mulberry leaf health food is very popular in developed countries, but it has not really started in China At present, China still has the largest mulberry population in the world, so the mulberry leaf resources are not rich All in all, the development of mulberry leaf health food market prospects are very broad.
