Mulberry enzyme preparation method

The invention provides a mulberry enzyme preparation method, which comprises the following steps: firstly, taking mulberries, cleaning, crushing, adding honey into the obtained mulberry pulp, dispersing, adding bifidobacterium longum, lactobacillus bulgaricus, and a mixed strain solution of lactobacillus acidophilus and streptococcus thermophilus, and fermenting at the temperature of 35-40 DEG C for 10-15 days; then filtering the fermentation broth by a plate frame to remove pomace, filtering the filtrate by an ultrafiltration membrane to obtain a mulberry enzyme extracting solution; taking gelatin, carbomer, sodium alginate, chitosan, polyethylene glycol andwater, mixing and carrying out ultrasonic dispersion to obtain a carrier solution; and finally, adding the mulberry enzyme extracting solution into the carrier solution, mixing, carrying out reduced pressure evaporation at the temperature of 50-70 DEG C to obtain a gel solution, and freeze-drying to obtain mulberry enzyme.
