The highland barley beta-
glucan enrichment method comprises the following steps of
raw material pretreatment, ultrasonic-
microwave synergistic extraction, composite enzymolysis,
enzyme deactivation and concentration, and during preparation, the highland barley beta-
glucan enrichment method comprises the following steps of dough preparation, standing for relaxation, tabletting forming and two-stage baking. The method disclosed by the invention has the beneficial effects that the yield of the beta-
glucan reaches 2.36% and the content of the beta-glucan in the enriched
powder reaches 8-10% through ultrasonic-
microwave synergistic and composite enzymolysis technologies, so that a foundation is laid for preparation of high-
fiber products; through the synergistic effect of the low-
gluten wheat flour and the
baking powder and in combination with a standing
relaxation process, the molding rate of the highland barley cakes reaches 98% or above, and baking shrinkage and fragmentation are avoided; the content of beta-glucan in the finished product is more than or equal to 12%, and the total
dietary fiber is more than or equal to 12%; the
hardness of the product is less than or equal to 800g through two-stage baking, the product is crispy and not rough in taste, and the yak milk
powder and the sea buckthorn fruit
powder endow unique
flavor.
