Embodiment 1

[0017] Example 1, the Jinshuai apples were inspected, washed, crushed, and squeezed into juice, stored in a juice collection tank, and parked for 1 hour to fully brown the juice. The juice entered the evaporator and raised to 85°C, After cooling down to 55°C, enter the enzymatic hydrolysis tank for enzymatic hydrolysis, add pectinase and amylase to the enzymatic hydrolysis tank, and after 1 hour of enzymatic hydrolysis, the reaction is negative, then park for 1 hour, add 120 mesh activated carbon, the amount of activated carbon added is 10Kg / 20T, Absorbed and stabilized for 6 hours, poured into the residence tank, entered the ultrafiltration system, removed insoluble matter and other impurities, obtained apple juice, concentrated, obtained concentrated juice, collected in the finished product tank, concentrated juice was sterilized by high temperature and then produced The aseptic filling machine fills the finished product.

Embodiment 2

[0018] Example 2: Fruit-checking, fruit-washing, crushing, and squeezing of rich-earth apples are carried out into fruit juice, stored in a juice collection tank, and parked for 1.5 hours to fully brown the fruit juice. The fruit juice enters the evaporator and heats up to 80°C. After cooling down to 50°C, enter the enzymatic hydrolysis tank for enzymolysis, add pectinase and amylase to the enzymatic hydrolysis tank, and after 1 hour of enzymolysis, the reaction is negative, then park for 2 hours, add 200 mesh activated carbon, the amount of activated carbon added is 8Kg / 20T, Absorbed and stabilized for 8 hours, poured into the residence tank, entered the ultrafiltration system, removed insoluble matter and other impurities, obtained apple juice, concentrated, obtained concentrated fruit juice, collected in the finished product tank, concentrated juice was sterilized by high temperature and then produced The aseptic filling machine fills the finished product.

Embodiment 3

[0019] Example 3: Xiaoguoguang apples were inspected, washed, crushed, and squeezed into fruit juice, stored in a juice collection tank, and parked for 0.5 hours to fully brown the juice. After cooling down to 53°C, enter the enzymatic hydrolysis tank for enzymatic hydrolysis, add pectinase and amylase to the enzymatic hydrolysis tank, after 1 hour of enzymatic hydrolysis, the reaction is negative, then park for 1.5 hours, add 150 mesh activated carbon, the amount of activated carbon added is 15Kg / 20T, Absorbed and stabilized for 7 hours, poured into the residence tank, entered the ultrafiltration system, removed insoluble matter and other impurities, obtained apple juice, concentrated, obtained concentrated juice, collected in the finished product tank, concentrated juice was sterilized by high temperature and then produced The aseptic filling machine fills the finished product.

Abstract

The invention discloses a processing method for eliminating secondary precipitation of concentrated apple clear juice, which comprises the following process steps: freshly squeezed juice; browning, placing the juice in a juice collection tank for 0.5-1.5 hours to fully brown the juice ; gelatinization; enzymatic hydrolysis, gelatinized fruit juice enters the enzymatic hydrolysis tank, add pectinase and amylase in the enzymatic hydrolysis tank, after the reaction is negative, after parking for 1-2 hours, add 120-200 mesh activated carbon, the adsorption is stable 6-8 hours; ultrafiltration, concentration, and packaging of finished products are a processing method that effectively eliminates the secondary precipitation of concentrated apple juice, thereby improving the internal quality of concentrated apple juice.

Description

(1) Technical field: [0001] The invention relates to the technical field of fruit juice processing, in particular to a processing method for eliminating secondary precipitation of concentrated apple clear juice. (two) background technology: [0002] At present, in the deep processing industry of apples, the industrialization level is relatively high. The conventional processing technology of the concentrated apple juice is freshly squeezed juice, gelatinization and anti-browning, enzymolysis, adsorption, ultrafiltration, concentration, and finished products. After storage, the processed concentrated apple juice is prone to smoke-like substances, which are called secondary precipitation, which seriously affects the internal quality of concentrated apple juice. Therefore, a processing method that can effectively eliminate the secondary precipitation of concentrated apple juice has not been seen so far. . (3) Contents of the invention: [0003] The purpose of the present inv...
