The invention discloses a food for controlling postprandial
blood sugar based on compound
fermentation of
plant raw materials and a preparation method of the food, and relates to the technical field of
fermentation processing of functional foods and natural products. The
sugar-controlling food contains
plant raw material composite ferment
powder, and a preparation method of the ferment
powder comprises the following steps: S1, mixing
mulberry leaf powder, buckwheat powder and soybean powder in proportion, and adding water to prepare a mixture with the
water content of 55-60%; s2, inoculating a
sugar-inhibiting eurotium cristatum liquid into the mixture, and performing
solid-state
fermentation to obtain a first fermented material; s3, inoculating the first fermented material with a
lactobacillus plantarum bacterial liquid for
continuous fermentation to obtain a second fermented material; and S4, carrying out
enzyme deactivation, cooling, homogenizing,
drying and crushing on the second fermentation material to obtain the
plant raw material composite fermentation powder. The fermentation method disclosed by the invention not only can improve the content of hypoglycemic active ingredients and the inhibition rate of alpha-
glucosidase, but also can reduce the bitterness of the active ingredients and balance the mouth feel.
