The invention discloses an oat
dietary fiber beverage and a preparation method thereof. The oat
dietary fiber beverage is prepared through the following steps: cleaning oats to remove impurities, killing enzymes, carrying out
drying and pulverizing, blending
slurry, adding
barley malt for
enzymatic hydrolysis, carrying out filtering, then blending
dietary fiber, adding certain amounts of a stabilizing agent and a
flavor auxiliary agent in proportion, and carrying out homogeneous sterilization and hot filling so as to be able to obtain the oat dietary
fiber beverage. According to the invention,by utilization of the characteristics of rich containment of amylases and
proteases and low price of
barley malt powder, the oat dietary
fiber beverage is prepared by addition of the
barley malt powder instead of addition of amylases, so the cost of an
enzyme preparation in the production process can be reduced; meanwhile, the oat dietary
fiber beverage generates the color,
flavor and taste of the barley malt, and the contents of proteins, peptides and amino acids in the oat dietary fiber beverage can be improved; and through blending of the
soluble dietary fiber of
oat bran, the oat dietaryfiber beverage additionally achieves the functions of reducing
blood sugar and blood fat, preventing
constipation and the like, so the characteristic of increasing the nutritional value and health-care function of the oat dietary fiber beverage is achieved.
