Abstract

The present invention discloses a method for fermenting purple sweet potato pulp by using plant probiotics and solves problems of poor flavor, high processing cost and serious nutrient loss in processing of purple sweet potato pulp products. The method specifically comprises steps of pretreatment, crushing, softening, cooking, enzymolysis, pulping, blending, primary sterilization and cooling, fermentation, centrifugation, degassing, homogenization, secondary sterilization and cooling, aseptic cold filling, etc. A probiotics fermentation technology is used, so that the purple sweet potato pulpproduces lactic acid and salt substances thereof with a fresh-keeping effect, produces better fermentation flavored and micro-organism-inhibiting substances, and the method improves fragrance and mouthfeel of the purple sweet potato pulp, at the same time effectively reduces sterilization conditions of the purple sweet potato pulp, saves costs, at the same time preserves nutrient components of purple sweet potatoes, increases nutrition of a fermentation product and also prolongs shelf life of purple sweet potato product raw materials.

Description

technical field [0001] The invention relates to the technical field of deep processing of fruits and vegetables, in particular to a method for fermenting purple sweet potato pulp by plant probiotics. Background technique [0002] At present, domestic purple sweet potato products are mainly sold in the form of their original fruit, and fermented purple sweet potato pulp products are rarely seen. The main reason lies in several major difficulties in the purple sweet potato processing process: [0003] 1) The starch content in purple sweet potato is relatively high and cannot be eaten raw. It needs to be cooked to hydrolyze the starch material before it can be absorbed by the human body. Therefore, the energy consumption in the processing process is relatively large, and the product properties will be greatly changed; [0004] 2) The taste of purple sweet potato is not good after pulping, the pH value is low, and the risk of introducing microorganisms is high. Similar products ...
