1, β-glucan: According to the data of Xizang Autonomous Region Institute of Agriculture and Animal Husbandry, highland barley has the highest β -glucan content in wheat crops in the world. According to the test, the average β -glucan content of highland barley is 6.57%, and the excellent variety highland barley 25 is 8.6%, which is 50 times of the average content of wheat. β -glucan indirectly inhibits the biological effects of carcinogens by reducing the contact between intestinal mucosa and carcinogens, thus preventing colon cancer; Preventing cardiovascular diseases by reducing the synthesis of blood lipids and cholesterol: preventing and treating diabetes by controlling blood sugar. It has the functions of improving the body's defense ability and regulating the circadian rhythm. According to American scientific research, in addition to β-glucan, highland barley also contains a special cholesterol inhibitory factor, and its content is about 0/00-150 mg per kilogram.
2. Dietary fiber: The total therapeutic fiber content of highland barley is 16%, including 9.68% insoluble therapeutic fiber and 6.37% soluble therapeutic fiber. The former is 8 times that of wheat, and the latter is 15 times that of wheat. The content of single glucan is 6.57%, which is only 0. 1 percentage point lower than oats and 50 times higher than wheat. Dietary fiber is a scavenger of human digestive system, which has good effects of clearing the bowels, relaxing bowels and eliminating toxins in the body.
3. Amylopectin: The composition of highland barley starch is unique, generally containing 74-78% amylopectin. In recent years, the amylopectin content of highland barley 25, a new variety cultivated by Xizang Autonomous Region Agriculture and Animal Husbandry Department, has reached or approached 65,438+000%. Amylopectin contains a lot of gelatinous mucus, which is weakly alkaline after heating and has an inhibitory effect on hyperacidity. Can relieve and protect the focus.
4. Rare nutrients: Every 100g of highland barley powder contains 0.32mg of thiamine (vitamin B1), 0.21mg of riboflavin (vitamin B2) and 3.6mg of nicotinic acid; Vitamin E 0.25mg. These substances have a positive effect on promoting the healthy development of human body.
5. Trace elements: calcium, phosphorus, iron, copper, zinc, trace element selenium and other mineral elements beneficial to human health. Selenium is an essential trace element for human body determined by the United Nations Health Organization, and it is also the only anticancer element determined by the organization at present.
