Abstract

The invention discloses a method for preparing bambusa chungii liquid. The method comprises the following steps of pulping bambusa chungii, carrying out high-pressure treatment, carrying out enzymolysis, then, carrying out microfiltration, and sterilizing. According to the method, no food additive is added, and ultrahigh temperature is adopted to instantly sterilize bacteria, so that the nutrition and flavor of the bambusa chungii are preserved, and the bambusa chungii liquid is faint scent and slightly sweet; cane sugar is not artificially added, so that health problems resulting from the addition of white granulated sugar are avoided, and the bambusa chungii liquid is natural and healthy and meets the increasing demands of people on the safety, nutrition, flavor and taste of beverages.

Description

technical field [0001] The invention relates to a method for preparing a beverage, in particular to a method for preparing Danzhu liquid. Background technique [0002] Red bamboo, also known as pink single bamboo, scientific name: Bambusa chungii, is a species of Poaceae Bougainvillea genus, with a stalk height of 3-7m, a diameter of about 5cm, and a very long top drooping. When the stalk surface is young, it is densely covered with white powder. 30--60cm long, with many and nearly equal branches at each node. Produced in the south, the main producing areas are Guangdong, Guangxi, Fujian and Hunan. Danzhu liquid is the liquid contained in the body of Danzhu, which is rich in amino acids, metasilicate, multivitamins and more than 20 kinds of trace elements such as selenium, germanium, strontium, zinc, iron, etc. It has the functions of quickly quenching thirst, preventing getting angry, It has the effects of sobering up and enhancing physical fitness, and it is non-toxic an...
