Process for producing enzyme by orange segmented fermentation method

The invention discloses a process for producing enzyme by an orange segmented fermentation method, and relates to the technical field of orange fermentation product processes. The process comprises the following steps: 1) raw material preparation, 2) strain propagation, 3) cleaning, 4) sterilization, 5) crushing, 6) lactic acid bacteria fermentation, 7) yeast fermentation, 8) fruit vinegar fermentation, and 9) deep fermentation. According to the invention, the product form of orange processing is increased; through segmented complete fermentation, the consumption safety as food is guaranteed, the taste of the product is rich, and specific aromatic substances, nutrient substances and some antioxidant substances of the oranges are reserved; through low-temperature treatment, the enzyme activity is maintained, and the health-care value of the oranges is improved; and through three-stage fermentation treatment, the obtained enzymes and metabolite products are rich, the varieties of the enzymes and active substanc
