Problems solved by technology

The total amino acid content is 0.254%, which is higher than that of hawthorn, which is rich in amino acids, and is rich in nutrition. However, most of the blueberry concentrated juices currently on the market have lost the active components of anthocyanins in blueberries due to high-temperature sterilization treatment, resulting in reduced effects.

Abstract

The invention discloses a concentrated blueberry juice and a preparation method thereof. The concentrated blueberry juice is prepared from the following raw materials in parts by weight: 50 to 55 parts of blueberries, 4 to 8 parts of pectinase, 7 to 12 parts of grape skin, 17 to 20 parts of tremella fuciformis, 4 to 6 parts of shell powder, 15 to 17 parts of cranberries, 5 to 7 parts of black rice, 1 to 3 parts of tartaric acid, 3 to 7 parts of coenzyme, 11 to 13 parts of atap seeds, 1 to 3 parts of edible salt, 11 to 13 parts of edible alcohol and 1 to 3 parts of sodium citrate. The concentrated blueberry juice disclosed by the invention has a good taste, reserves a large amount of anthocyanin active ingredients in the blueberries and has the functions of activating retinas, promoting the regeneration of rhodopsin in retina cells, preventing myopia, increasing the eyesight and removing eye fatigue.

Description

technical field [0001] The invention relates to a concentrated blueberry fruit juice and a preparation method thereof. Background technique [0002] Concentrated fruit juice is made by evaporating part of the water by low-temperature vacuum concentration after the fruit is squeezed into raw juice. When preparing 100% fruit juice, the natural water lost in the fruit juice concentration process must be restored in the raw materials of the concentrated fruit juice. An equal amount of water is used to make a product with the color, flavor and soluble solid content of the original fruit pulp. [0003] The average weight of blueberry fruit is 0.5-2.5g, and the maximum weight is 5g. The color of the fruit is beautiful, pleasing to the eye, blue and covered with a layer of white fruit powder. The flesh is fine and the seeds are very small. The edible rate is 100%. It is a good fresh food. In addition to conventional sugar, acid and Vc, blueberry fruit is rich in VE, VA, VB, SOD, a...
