Embodiment 1

[0038] Take 550Kg of fresh apples and wash them, manually screen to remove impurities and rotten apples, and measure 500Kg of raw materials. The 500Kg apples that are screened are cleaned and drained through a trough type fruit washer. The apples that have been washed and drained are first pulverized with a pulverizer, and then squeezed with an apple juicer to obtain 452Kg of apple juice (stored in a juice storage tank), and 47.6Kg of pomace. 452Kg apple juice in the juice storage tank is pumped into heat sterilization equipment through a raw material pump, and sterilized at 85-100°C for 4-5 minutes to obtain sterilized apple juice. Then add 22g of pectinase and 115g of gelatin to the 452Kg of apple juice obtained by pasteurization, and enzymolyze it for 60 to 80 minutes at a pH of 3.4 to 3.5 and a temperature of 35 to 55°C (if necessary, take a sample and use an iodine reagent to test the starch The degree of hydrolysis until the hydrolysis is complete, the same below).

Abstract

The invention discloses a method for separating proteins, apple polyphenol and pigments from apple juice. According to the method for separating the proteins, the apple polyphenol, the apple starch and the pigments from the apple juice, the color value of the apple juice is decreased, the quality of the apple juice is improved, and the comprehensive utilization of decolorized byproducts of the apple juice is improved. The method comprises the following steps: screening, cleaning, draining, crushing and squeezing the raw materials, so as to obtain the apple juice and apple pomace; carrying outpasteurization on the apple juice, adding pectinase and gelatin into the apple juice for enzymolysis; carrying out tubular ultrafiltration clarification, so as to obtain clean apple juice, macromolecule proteins, cellulose, starch and a pectin byproduct; carrying out roll type ultrafiltration separation, so as to obtain purified clean apple juice and a concentrated solution rich in apple polyphenol, micromolecule proteins and pigments; adsorbing the clean apple juice so as to remove pesticide residue and heavy metals, and concentrating; and carrying out ultrahigh-temperature instant sterilization on the apple juice.

Description

technical field [0001] The invention relates to the separation of organic components in fruit juice, in particular to a method for separating protein, apple polyphenols, apple starch and pigment in apple juice based on the combination of tubular ultrafiltration clarification and roll ultrafiltration separation. technical background [0002] As a neutral drink, apple juice is very popular among people. my country is the main apple producing country in the world, and its annual output ranks among the top in the world. Due to the convenient transportation and storage of concentrated apple juice, it has become the main direction of apple deep processing in my country. In recent years, with the introduction of a large number of foreign advanced equipment, especially the appearance of membrane separation equipment, the processing technology level of apple juice in my country has been greatly improved. The output of concentrated apple juice in my country has leapt to the first pla...
