Abstract

The invention discloses a preparation method for a tea-lactic acid beverage, which belongs to the technical field of processing of lactic acid beverages. The tea-lactic acid beverage is prepared from tea and white sugar. The preparation method comprises the following steps: putting tea and white sugar into a pot, adding mountain spring water, successively carrying out boiling and then cooling, and carrying out filtering so as to obtain leaching liquor; pouring the leaching liquor into a clean container, inoculating a lactic acid bacterium strain, carrying out uniform mixing with stirring and capping the container for fermentation; controlling the number of live bacteria in a material liquid obtained after fermentation, wherein the content of live lactic acid bacteria in the material liquid is 500, 000 to 1000, 000 / ml; adjusting acidity of the material liquid, controlling temperature to be 16 to 28 DEG C and controlling the total acid content of the material liquid to be 0.1 g to 0.15 g / 100 ml; and sterilizing the material liquid having undergone acid adjustment and carrying out vacuum aseptic filling. The tea-lactic acid beverage prepared in the invention is rich in nutrients, has the delicate fragrance of tea, is tasty and can quench thirst and be easily absorbed by the human body.

Description

technical field [0001] The invention relates to the field of beverage processing, in particular to a method for preparing tea lactic acid beverage. Background technique [0002] Fermented tea drinks use tea sugar water as the main matrix, and some nutrients, such as lactic acid bacteria, are added to it. Through their metabolism, the tea water undergoes profound benign physiological and biochemical changes, thereby improving the quality of tea sugar water. Lactic acid bacteria fermented tea sugar water drink is a special fermented tea drink, which belongs to the emerging health tea drink. After the tea sugar water is fermented by lactic acid bacteria, it can increase many active ingredients of microbial metabolism and the bacteria itself, and the quality is greatly improved. . Lactic acid bacteria is a general term for a group of Gram-positive bacteria that produce large amounts of lactic acid from fermentable carbohydrates. It is widely present in the intestinal tract of ...
