Abstract

The invention relates to a method for preparing bamboo leaf ferment and a bamboo leaf ferment beverage with bamboo leaf submicron powder, and belongs to the engineering field of fermentation techniques. The method comprises the following steps of (1) pretreating raw materials; (2) performing ultrafine crushing; (3) performing pressure treatment; (4) performing enzymolysis; (5) mixing materials; (6) performing microbial fermentation; and (7) performing fermentation post-treatment. The bamboo leaf submicron powder ferment prepared by the method is free from any preservatives and additives, through microbial fermentation, and under the action of beneficial bacterial flora of lactic acid bacteria, microzymes and the like, composite fermentation is performed, so that purely natural bamboo leafsubmicron powder ferment is obtained. According to the method, active components in bamboo leaves can be well reserved, and the bamboo leaf ferment is rich in nutrients, natural, environment-friendly,and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of fermentation technology engineering, and in particular relates to a method for preparing bamboo leaf enzyme and bamboo leaf enzyme beverage from bamboo leaf superfine powder. Background technique [0002] Bamboo is a perennial evergreen plant of the Poaceae Bamboo subfamily, widely distributed in tropical, subtropical and warm temperate regions, and is one of the most valuable plants in the world today. There are more than 70 genera and more than 1,200 species in the world, and the bamboo forest area is about 21 million hectares. The existing bamboo forest area in my country is 5.2 million hectares, accounting for nearly 1 / 4 of the world's total bamboo forest area, mainly distributed in Fujian, Jiangxi, Zhejiang and other provinces. [0003] Bamboo leaves are widely used among the Chinese people, and have a long history of medicinal and edible use. They are good heat-clearing and detoxifying medicines. According t...
