Preparation method of highland barley bran tea rich in water-soluble dietary fiber

Abstract

The invention relates to a preparation method of a highland barley bran tea rich in water-soluble dietary fiber. The method includes the steps of: (1) dehulling highland barley, sieving first layer bran powder to remove large highland barley particles, broken grains, and other impurities, and taking the undersize product; (2) bursting the highland barley bran obtained in step (1) to obtain steam blasted bran material; (3) carrying out baking, crushing and sieving on the steam blasted bran material to obtain highland barley bran powder; (4) crushing chrysanthemum buds and French rose respectively and performing sieving, thus obtaining chrysanthemum bud powder and rose powder respectively; (6) by weight, mixing 1-2 parts of the chrysanthemum bud powder, 0.5-1.5 parts of the rose powder, 0.2-0.8 part of Chinese wolfberry powder, and 5-10 parts of highland barley bran powder evenly to obtain mixed powder; and (7) adding water into the mixed powder, mixing the substances evenly, and then conducting granulation and drying so as to obtain the highland barley bran tea with a water content of less than or equal to 10%. The highland barley bran tea prepared by the method provided by the invention has a high content of soluble dietary fiber, and the preparation method has the advantages of simple production process, easy mastering and low production cost.

Description

technical field [0001] The invention relates to a tea product, in particular to a preparation method of highland barley bran tea rich in water-soluble dietary fiber. Background technique [0002] Highland barley, also known as rice wheat, rye, or barley, is a variety of barley. Highland barley is a very important cereal crop in plateau areas because of its tolerance to high cold and barrenness. Highland barley is the one with the highest β-glucan content in cereal crops. According to the test, the average content of highland barley β-glucan is 5.25%. At the same time, the total dietary fiber content in highland barley is 16%, of which the insoluble dietary fiber is 9.68%, and the soluble Dietary fiber is 6.32%, the former is 8 times that of wheat, and the latter is 15 times that of wheat. It is the "scavenger" of the human digestive system. Its ecological characteristics and nutritional and health effects are unmatched by other food crops. The functional ingredient β-gluca...

Problems solved by technology

The functional ingredient β-glucan in highland barley is mainly gathered in highland barley bran, the content is generally between 3% and 7%, and highland barley bran is directly removed during processing and utilization, and is purchased at a low price or directly added When used in feed, the utilization rate of its by-products is extremely low, which seriously restricts the effective development and utilization of highland barley resources.
