The invention discloses a preparation method of a fat-
free cholesterol-free
lactic acid bacteria beverage fermented with
egg white. The method comprises the following steps of separating
yolk from eggwhite; mixing the
egg white with water,
carbohydrate substances,
sodium acetate,
citric acid triamine and
inorganic salts in proportion, performing uniform stirring, and performing heating to 70-90 DEG C so as to obtain liquid to be fermented; after heating is completed, cooling the liquid to be fermented, then adding a fermenting agent, performing uniform mixing, and performing constant-temperature
fermentation; and sequentially performing dispersing, homogenizing,
cold storage and after-
ripening on
fermentation products so as to obtain the fat-
free cholesterol-free
lactic acid bacteria beverage. According to the preparation method disclosed by the invention, the market blank of high-
protein beverages is filled, and the
fermentation of the
lactic acid bacteria beverage is performed withthe
egg white; besides, through heating,
antifungal protein is denatured, the
antibacterial activity is restrained, and growth of lactic acid bacteria is promoted; and besides, through adding the
carbohydrate substances, the
inorganic salts and the growth factors, favorable conditions are provided for the growth of the lactic acid bacteria, so that the fat-
free cholesterol-free lactic acid bacteria beverage which is large in the number of the lactic acid bacteria and rich in
protein content is obtained.
