Blueberry fruit powder and blueberry fruit reduction juice and production method thereof

Abstract

The present invention discloses blueberry fruit powder and blueberry fruit reduction juice and a production method thereof. The production method includes the following steps: (1) pretreatment; (2) beating treatment; (3) ultrasonic treatment; (4) filtration; (5) blueberry juice concentrate preparation; (6) blueberry fruit powder preparation; and (7) blueberry fruit reduction juice preparation. The production method develops the blueberry fruit powder and the blueberry fruit reduction juice which are high in functional component contents, conducive to storage and transportation, sale and consumption; when producing the blueberry fruit powder, trehalose phosphate solution is creatively used to process blueberry fruit pieces, playing roles of trehalose and phosphate in protecting and stabilizing blueberry fruit cells and functional materials; the ultrasonic treatment is carried out when producing the blueberry fruit powder, enhancing permeability of the blueberry fruit cells, and making the trehalose and the phosphate more likely to enter the cells to play a protective role.

Description

technical field [0001] The invention belongs to the technical field of fruit powder and fruit juice production, and in particular relates to blueberry fruit powder, blueberry fruit reduced juice and a production method thereof. Background technique [0002] Blueberry juice is rich in vitamins and amino acids. Blueberry juice is rich in anthocyanins, which can scavenge oxygen free radicals, protect eyesight, delay brain aging, and improve memory. Due to the unique effect of blueberries on protecting and enhancing eyesight, blueberries are also known as "the pilot's breakfast", which is the designated breakfast food for pilots designated by the British and American Air Forces. [0003] Existing blueberry juice is generally freshly squeezed, but due to the high water content and heavy weight, it is very unfavorable for storage and transportation, which affects the sales of blueberries. At present, in the field of fruit juice production, in order to reduce the water in the frui...
