Highland barley, also called rice barley, naked barley, etc., is a variety of barley, belonging to the grassy, annual or perennial herb plants. Wherein the starch and protein content is high, various amino acids and mineral elements are complete in species, the content is rich, has the structure composition of three high and two low (high protein, high fiber, high vitamin, low fat and low sugar), and is a good product in cereal crops. Beta-glucan is the main component of the endosperm of highland barley seeds and the cell wall of aleurone layer, and the highland barley contains about 5.25% of beta-glucan. At the end of the 80 s of the 20 th century, us scientists first found that beta-glucan in barley, particularly highland barley, has the effects of reducing blood lipid, reducing cholesterol, regulating blood sugar, resisting tumors and preventing cardiovascular diseases, and is attracting worldwide attention. Currently, the biomedical community also considers that beta-glucan has four functions of clearing intestines, regulating blood sugar, reducing cholesterol and improving immunity.
Highland barley powder has no agglomeration although the highland barley has higher protein content, so that highland barley is difficult to agglomerate in the bread making process and difficult to form a normal bread tissue state. The highland barley bread prepared by the highland barley powder sold in the market and the baking process has the problems of coarse taste, small specific volume, low bread texture and the like.
