Blueberry pressed candy with high contents of viable probiotics and preparation method thereof

Abstract

The present invention discloses a blueberry pressed candy with high contents of viable probiotics and a preparation method thereof, and belongs to the technical field of deep processing of blueberries. The preparation method includes: processing blueberries serving as raw materials into blueberry pulp by a non-thermal processing method, evenly mixing the blueberry pulp with milk, saccharose, Chinese herbal medicine extract, honey and stabilizing agents, fermenting the mixture with the addition of fermentation agents and preparing the fermented mixture into blueberry yogurt using a stage temperature shift fermentation method so as to maximize the proliferation of probiotics and to make the probiotics have good resistance to cold and heat stress, freeze-drying the blueberry yogurt into powder with the addition of protective agents with a good anti-freeze effect to obtain functional blueberry yogurt freeze-dried powder with high contents of viable probiotics and strong resistance to cold and heat, and finally scientifically compounding the functional blueberry yogurt freeze-dried powder with alfalfa extract, germinated brown rice, plant extract, dextrin, probiotic factor, magnesium stearate, etc., and pressing with a multi punch rotary tablet pressing machine to prepare the blueberry pressed candy. The blueberry pressed candy is high in contents of viable probiotics, and long in shelf life, can improve human immunity and delay senescence, and has effects in beautifying countenance and maintaining beauty and resisting bacteria.

Description

AI Technical Summary

Problems solved by technology

The content of live lactic acid bacteria or probiotics in the patents disclosed above is still low, the fermentation strains are too traditional, and their functionality is poor. Separately freeze-drying fruits and vegetables and yogurt consumes a lot of time and energy. Large loss of nutrients, traditional processing of pulp results in low soluble cellulose content, poor stability, and short shelf life
