Abstract

The invention discloses a production method of lactic acid bacteria fermented blueberry juice, which is characterized in that it comprises the following steps: (1) adding a compound lactic acid bacteria starter into MRS broth medium for activation, and then sequentially taking bacterial liquid (2) select fresh blueberries, wash them, and blanch them in water; (3) squeeze the blueberries into blueberry juice, and grind them in a colloid mill; finally add sucrose to adjust the sugar content of the blueberry juice; (4) ) putting the ground blueberry juice into a hot water bath; (5) inserting the activated strain into the blueberry juice processed in step (4); then putting it into an incubator for fermentation; the fermented blueberry juice Water bathing in hot water to obtain lactic acid bacteria fermented blueberry juice. The preparation process of the invention is simple, the product has good flavor and rich nutrition. The lactic acid bacteria fermented blueberry juice drink prepared by the process of the invention has a round mouthfeel, excellent flavor, sweet and sour taste, can be directly drunk, and has a better frozen flavor.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of lactic acid bacteria fermented blueberry juice. Background technique [0002] Blueberry, the fruit is a berry, blue in color, with delicate flesh and tiny seeds, sweet and sour, and has a refreshing and pleasant aroma. Blueberries are rich in nutrients, not only rich in conventional nutrients such as sugar, acid, and VC, but also extremely rich in flavonoids and polysaccharides. Blueberry fruit has the functions of preventing brain nerve aging, enhancing heart function, improving eyesight and anti-cancer, enhancing human body immunity, and treating urinary system infection. One (Ma Yubo et al., Research on lactic acid bacteria beverage of wild blueberry juice [J], 2009, 30(7), 78-81). Most of the blueberries in the market are processed into blueberry juice drinks and blueberry fruit wine drinks. Lactic acid bacteria are a type of probiotic bacte...
