[0027] A preparation method of apple cider vinegar, the preparation method comprising the following steps:
[0028] (1) After washing the apples with water, cut them into pieces, put them in a juicer to squeeze the juice, and obtain the squeezed juice. The squeezed juice is centrifuged and filtered under the condition of 3000~4000r / min to obtain the filtrate. The mass ratio is 10-15: 1~2: 0.8~1, mix the filtrate, pectinase, potassium metabisulfite, enzymatically hydrolyze at 50~60℃ for 80~90min, clarify, then inactivate the enzyme at 95~100℃ for 5~8min , Adjust the sugar content to 13~14% to get the mixed solution;
[0029] (2) According to the mass ratio of 10~15:1~2, put the mixed liquor into the fermentation tank and insert the activated yeast for wine, and ferment at 25~30℃ for 5~8 days to obtain the fermentation broth. Wash and air dry to obtain the dried edible fungus. The dried edible fungus is crushed to obtain the crushed product. According to the mass ratio of 1:3~4, the...
