Embodiment 1

[0019] (1) First, store freshly picked blueberries in quick-frozen storage, and then steam iron for 10 minutes until the surface skin is softened, thawed, and peeled. The pulp is then thawed at 4°C for 6 hours, and then the blueberry pulp is obtained by squeezing the pulp with a pulping machine. Add the same amount of deionized water and stir to dilute, and then add the total amount of 0.6% pectinase preparation and 0.4% cellulase preparation according to the total amount. Incubate in a water bath at 50°C and stir slowly. After combined enzymatic hydrolysis, heat to 90°C for 3 hours. Enzyme 5min, and finally 4000r / min centrifugation for 15min to separate the clear blueberry juice and blueberry residue.

[0020] (2) Mix the blueberry peel with the pulp residue, freeze at a low temperature of -30°C, and then vacuum and room temperature drying for about 20 hours for drying, grind the powder through an 80 mesh sieve, and add deionized water according to the material-to-liquid ratio of...

Abstract

The invention relates to a preparation method of a blueberry fruit clear juice sour beverage. The method comprises the following steps of pretreating blueberry fruits, separating peel from fruit flesh, preparing clear juice from the fruit flesh, treating the peel, mixing the treated peel with auxiliary materials, performing fermentation, finally, leaching fermentation products, and mixing a leaching solution with the clear juice. Through leached anthocyan, the problem that the clear juice beverage is insufficient in color is just solved, and besides, the anthocyan is natural pigment and has the efficacy of protecting eyesight; ethanol can also extract pectin components, the pectin exists in most of the fruit peel, under the condition of microwave pretreatment, the pectin easily dissolves, and the extracted peel pectin can facilitate the finished beverage product to easily present gelatiniform. The components are uniformly mixed, and the phenomenon of precipitation is not liable to generate.

Description

Technical field [0001] The invention belongs to the technical field of food technology, and specifically relates to a preparation method of a blueberry clear juice sour drink.
