Embodiment 1

[0073] see figure 1 Block diagram of the process route. Take 540Kg 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 unti...

Embodiment 2

[0084] Take 535Kg of fresh apples and wash them, artificially screen out 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.

[0085] The apples that have been washed and drained are first pulverized with a pulverizer, and then squeezed with an apple juicer to obtain 450Kg of apple juice (stored in a juice storage tank), and 49.5Kg of pomace. 450Kg apple juice in the storage tank is pumped into heat sterilization equipment through a raw material pump to sterilize at 85-100° C. for 5 minutes to obtain sterilized apple juice. 21g of pectinase and 120g of gelatin are added to 450Kg of apple juice obtained by pasteurization, and the enzyme is hydrolyzed for 70min under the condition of pH value of 3.4-3.5 and temperature of 35-55°C.

[0086] Pump the enzymolyzed apple juice into a tubular ultrafiltration system with a molecular weight cut-off of 150,000 for ultrafiltration...

Embodiment 3

[0092] Take 535Kg of fresh apples and wash them, artificially screen out impurities and rotten apples, and measure 500Kg of raw materials. The 500Kg apples of gained are cleaned and drained through a trough type fruit cleaner.

[0093] The apples that have been washed and drained are first pulverized with a pulverizer, and then squeezed with an apple juicer to obtain 454Kg of apple juice (stored in a juice storage tank), and 45.6Kg of pomace. 454Kg apple juice in the storage tank is pumped into heat sterilization equipment through a raw material pump and sterilized at 85-100° C. for 4 minutes to obtain sterilized apple juice. 23g of pectinase and 118g of gelatin were added to 454Kg of apple juice obtained by pasteurization, and enzymolysis was carried out for 80min at a pH value of 3.4-3.5 and a temperature of 35°C.

Abstract

The present invention is one kind of tubular ultrafiltering and clarification and reeling ultrafiltering and separation combined process for separating apple protein, apple polyphenol, apple starch and pigment from apple juice. The process can lower the color value of apple juice, raise the quality one apple juice and utilize apple juice comprehensively. The process includes the steps of material screening, washing, drying, crushing and squeezing to obtain apple juice and apple residue, pasteurizing, enzymolysis with pectase and gelatinase, tubular ultrafiltering and clarification to obtain clear juice, great molecular weight protein, cellulose, starch and pectin, reeling ultrafiltering and separation to obtain purified juice and concentrate with rich apple polyphenol, small molecular weight protein and pigment, treating clear apple juice to eliminate pesticide residue and heavy metal and concentration, and ultrahigh temperature short-time sterilization of 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. Background technique [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...
