Problems solved by technology

But at present, the preservation of the flavor in green tea and the combination degree of the air bubbles are not high, and the flavor produced in the fermentation process will be taken away by the air bubbles. How to solve the problem of how to bring the air bubbles into the mouthfeel while retaining the flavor is the problem solved by the present invention.

Abstract

The invention belongs to the field of food, and relates to a probiotic fermented green tea sparkling beverage and a preparation method thereof. The preparation method comprises the following steps: washing a green tea raw material with water, carrying out superfine grinding, adding water, uniformly mixing, extracting, extruding and filtering to obtain a green tea stock solution, and cooling to room temperature for later use; adding carbohydrates into the obtained green tea stock solution to adjust the sugar degree, adjusting the pH value with citric acid, and then sterilizing; lactobacillus plantarum and yeast are inoculated into the sterilized stock solution at the same time for fermentation; and filtering the fermentation liquor to remove residues, bottling and sterilizing, and introducing clean carbon dioxide gas. The obtained fermented green tea sparkling beverage is rich in flavor, unique in taste, high in nutritional value and easy to industrially produce.

Description

technical field [0001] The invention belongs to the field of food, and relates to a probiotic fermented green tea bubble drink and a preparation method thereof. Background technique [0002] Green tea contains many beneficial ingredients such as tea polyphenols and catechins, which can remove viruses and bacteria in the mouth and throat, clear heat and detoxify, and clean the stomach. Some green teas are also effective for sore throat and cough. But some people don't like the bitter taste of tea. A popular traditionally fermented beverage fermented by adding yeast, the duration of this fermentation may range from 5 to 10 days under aerobic conditions. The ideal fermentation period is how green tea's finesse and taste are necessary to develop. Ultimately, the sugars are converted into organic acids. Green tea is fermented with a mixture of symbiotic flora. Sweetened tea, resistance, improves digestion, strengthens the immune system, reduces inflammation, polyphenols with an...
