Abstract

The invention discloses lactobacillus mixed fermentation rice drink and a preparation method thereof. The preparation method comprises the following steps of respectively adding beerwort and saccharifying enzyme in gelatinization liquid formed by steaming and gelatinizing rice flour and water, saccharifying the gelatinization liquid for 3 hours to 4 hours at the temperature of 60 DEG C to 65 DEG C to obtain saccharification liquid, adding lactobacillus zymophyte liquid, performing primary fermentation treatment for 70 hours to 80 hours at the temperature of 37 DEG C, performing secondary fermentation treatment for 12 hours to 20 hours at the temperature of 4 DEG C to 5 DEG C to achieve krausen liquid, adding white granulated sugar, homogenizing, canning, sterilizing and obtaining the required lactobacillus mixed fermentation rice drink. The constituents of the drink comprise 10 grams to 20 grams of total solid in per 100mL, 0.5 gram to 2.0 gram of protein in per 100mL and 9 grams to 18 grams of total sugar in per 100mL. The acidity of the drink is 60oT to 90oT. The drink uses lactobacillus mixed fermentation, thereby being rich in nutrition, fine and smooth in taste, strong in flavour and good in nutrition health care function.

Description

technical field [0001] The invention relates to the field of rice beverage preparation methods, in particular to a rice beverage fermented by lactic acid bacteria and a preparation method thereof. Background technique [0002] Rice has the effects of invigorating the spleen and nourishing the stomach, benefiting the essence and strengthening the will, improving ears and eyesight, and is known as "the first of the five grains". my country is the largest rice producer and consumer in the world. Rice accounts for about 2 / 5 of my country's total grain output and is one of the pillar industries of my country's grain industry. [0003] Rice beverage uses rice as the main raw material. Through modern beverage production technology, on the basis of retaining the nutritional value of rice, it is a new type of nutritional beverage that is further combined with beverage production. In foreign countries, especially in South Korea, the development of rice beverages has been relatively i...
