[0024] Weigh fresh pork bones and put them into a pulverizer for crushing for 1 hour. Sorting to obtain pork bone fragments with a particle size of 1mm, spread the obtained pork bone fragments on a stainless steel tray, and place the stainless steel tray at a temperature of 30°C 1. In a greenhouse with a relative air humidity of 70%, let it stand for moldy treatment for 3 days to obtain moldy pig bone fragments; transfer the obtained moldy pig bone fragments into a fermenter, and then add moldy pig bone fragments to the fermenter Deionized water of equal quality, stirred evenly, sealed the fermenter, sealed and fermented at a temperature of 38°C for 7 days, filtered and separated to obtain the filter residue after fermentation; the fermentation filter residue, tea polyphenol solution with a mass fraction of 40% and honey were pressed The mass ratio is 1:10:2, and the ultrasonic oscillator is used to ultrasonically oscillate and impregnate at a frequency of 25kHz for 30min, and ...
