Abstract

The invention discloses a method for preparing a beta-glucan highland barley hydrolyzed malt extract, belonging to the field of food processing. The method for preparing the highland barley hydrolyzed malt extract comprises the following steps: screening, pulverization and size mixing on raw materials, liquefaction, saccharification, filtration, concentration and drying. The highland barley malt extract is produced by directly adding exoenzyme, so that a highland barley germination process is saved and the production period is shortened. The beta-glucan malt extract product meets the requirements of some enterprises in markets, and fills a product blank. The protein content of the highland barley malt extract prepared by adopting the method is high and can reach over 4.5%, the reducing sugar content reaches over 47%, and beta-glucan, vitamin E, vitamin B and folic acid included in highland barley, minerals such as calcium, copper, iron, magnesium, manganese and zinc, and selenium element are reserved; and the malt extract also contains rich plant fibers, soluble sugar and carbohydrates, so that the malt extract has the effects of improving gastrointestinal functions, strengthening the spleen and stomach, eliminating fatigue and boosting the spirit.

Description

technical field [0001] The invention relates to a deep processing technology of highland barley, in particular to a preparation method of hydrolyzed barley essence rich in beta-glucan. Background technique [0002] Highland barley, English name hulless barley, is a kind of cereal crops of the genus Barley in the Poaceae family. Because of the separation of the inner and outer glumes and the bare kernels, it is also called naked barley, barley, and rice barley. Highland barley is mainly distributed in high-altitude alpine regions such as Tibet, Qinghai, and Sichuan in China. Highland barley has rich nutritional value and outstanding medical and health care functions. On the Qinghai-Tibet Plateau, which is cold and hypoxic, there are many centenarians. This is inseparable from the regular consumption of barley and the prominent medical and health care functions of barley. According to "Supplements to Materia Medica", it is recorded that highland barley has a wide airflow, st...
