Method for producing the jujube essence concentrated nutrient solution

Abstract

The invention relates to a method for preparing concentrated nutrient solution of jujube extract, which comprises following steps: (1) cleaning and screening checked jujubes; (2) extracting the jujubes obtained in step (1) in an extraction container for 120 min; (3) beating the product obtained in step (2), removing kernels, peeling by a defecator, and feeding the turbid juice containing flesh into a buffer tank; (4) subjecting the turbid juice obtained in step (3) to pasteurization and hydrolyzing with enzyme; (5) pumping the turbid juice obtained in step (4) to extraction equipment for extracting, and feeding the extractive solution into a buffer tank; (6) transporting the extractive solution obtained in step (5) to an ultrafiltering system for ultrafiltering; (7) feeding the clean juice obtained in step (6) to an evaporator for concentration, and feeding the extractive solution to a product tank when the sugar degree of the concentrated extractive solution is larger than 65 DEG BX;and (8) subjecting the juice obtained in step (7) to pasteurization and packaging. The nutrient solution prepared by the method is natural, and has no contaminant, good taste and long shelf life.

Description

technical field [0001] The invention relates to a method for extracting jujube juice, in particular to a method for preparing concentrated nutrient solution of jujube essence. Background technique [0002] At present, the method of extracting nutrient solution from jujube adopts the slag juice after crushing jujube, adds sugar, water, spices and preservatives, or adopts cooking, filtering and concentrating. These processing methods have destroyed the natural nutrition of jujube, the product is opaque, and even has sediment or suspended matter visible to the naked eye, and the jujube core, jujube skin, and jujube meat cannot be separated separately. The storage period is generally less than one year. All there are very big drawbacks and limitations on the storage period and storage period, and need to be improved. Contents of the invention [0003] The object of the present invention is to provide a kind of method for preparing jujube extract concentrated nutrient solution...
