Method for processing clear concentrated dark-plum juice

Abstract

A clarified concentrated plum juice with high output rate is prepared from green plum fruit through screening, washing, scaling, beating, enzymolyzing, deactivating enzyme, filtering, clarifying by chitosan, centrifugal separation, vacuum concentrating, sterilizing and aseptic packing.

Description

technical field [0001] The invention relates to food processing technology, in particular to the deep processing technology of clarified greengage concentrated juice. Background technique [0002] The clarification method of common greengage concentrated juice is 1. Gelatin tannin clarification method: add gelatin and tannin to the greengage juice to form gelatin-tannin complex precipitation, and other suspended particles are adsorbed on the complex and precipitate together. Promote the instability of colloidal substances and produce precipitation, and the green plum juice can be clarified. The disadvantage of this clarification method is that the material needs to be clarified for a long time, is easily contaminated by microorganisms, the yield of green plum juice is low, and the clarification effect is not ideal. 2. Pectinase clarification method: Use pectinase to decompose the pectin substances in the green plum pulp, hydrolyze the colloidal subst...

Problems solved by technology

The disadvantage of this clarification method is that when the amount of pectinase is small, the material needs to be clarified for a long time, and when the amount of pectinase is large, the production cost is high

And the clarification effect is not ideal, and the yield of green plum juice is low
