Embodiment 1

[0016] (1) Raw material pretreatment: select blueberries, remove mechanical bruises and blueberries that are damaged by diseases and insect pests, and then inject CO into the blueberries 2 After ripening for 2-4 days;

[0017] (2) Enzymolysis: After the ripening is completed, wash it with clean water, drain it, add 1 / 3 of the blueberry weight to drinking water and boil it slightly for 5 minutes, lower the temperature to 30°C, adjust the pH value to 3.5 with citric acid, add 0.1% EX pectinase, use 30°C water bath for 2 hours;

[0018] (3) Juicing and filtering: After enzymatic hydrolysis, use a juicer to squeeze the juice, filter the juice with a 20-mesh screen, then filter it for the second time with a 100-mesh screen, and then filter it for the third time with a 200-mesh screen. The filtrate after the first filtration is allowed to stand for clarification for 24 hours, and then filtered for the fourth time with a 300-mesh sieve to obtain the original juice of the blueberry j...

Abstract

The invention discloses a making method of blueberry juice drinks, which comprises the steps of: pretreatment of raw materials, enzymolysis, juicing and filtering, blending, sterilizing, bottling and the like. Compared with the prior art, the making method can ensure that the yield of juice reaches above 75 percent, the production cost is lowered, and the production period (2d) is shortened; and blended blueberry juice drinks are sterilized by using microwaves for 3-5min, thus brown stain of the blueberry juice can be effectively prevented, the quality guarantee period can reach 12 months, defects of loss and incompatibility of special natural fragrance of blueberry, poor special flavor and the like are reduced, thus massive and industrialized production can be realized; and meanwhile, the blueberry juice drinks are harmonized in flavor, and has special flavors such as purity, heavy flavor, elegance and compatibility.

Description

technical field [0001] The invention relates to the technical field of making fruit juice drinks, in particular to a method for making blueberry fruit juice drinks.
