The application belongs to the technical field of
food processing, and specifically provides a quinoa
blood sugar reducing tea, which comprises a fermented liquid of
lycoris radiata, medlar and quinoa in a
mass ratio of (10-20):(20-30):(50-70); the fermented liquid of quinoa comprises quinoa pulp and a compound
microbial agent; the compound
microbial agent comprises 0.5-0.8% of
monascus, 1-2% of
acetic acid bacteria and 0.8-1.2% of
yeast bacteria, based on the
mass of the quinoa pulp. The quinoa
blood sugar reducing tea provided by the application is rich in quinoa polyphenols, organic acids, peptides, amino acids,
soluble dietary fiber, enzymes and probiotics, can promote the absorption of phenolic components, thereby quickly inhibiting the activity of alpha-
amylase and alpha-
glucosidase, and plays a role in reducing
blood sugar. In addition, by compounding
inulin,
erythritol and gamma-
cyclodextrin, the bitter and
astringent taste of natural
polyphenol substances can be well covered, the sweet and sour is coordinated, the taste is delicate, and the
palatability is improved. The application also provides a preparation method of the above-mentioned quinoa blood
sugar reducing tea, which is simple in process, does not need to add an
organic solvent for extraction, is safe and efficient, and is suitable for industrial production.
