Abstract

The invention relates to a method for producing taro vinegar. The method comprises the steps of mixing taro and water and pulping to obtain taro pulp; treating the taro pulp with pectinase, cellulase and neutral protease to obtain enzymatically hydrolyzed taro pulp; treating enzymatically hydrolyzed taro pulp with medium-temperature amylase and glucoamylase to obtain saccharified taro pulp; then inoculating a saccharomycete suspension, and fermenting to obtain taro pulp alcoholic fermentation broth; inoculating an acetic acid bacteria suspension, and fermenting to obtain taro pulp acetic acid fermentation broth; adding chitosan, treating and separating by centrifugation to obtain taro vinegar and finally pasteurizing to obtain a taro vinegar finished product. The taro vinegar is clear and transparent bright yellow and thick in sourness and the total acidity based on acetic acid is 3%-6%. Since the taro vinegar disclosed by the invention is rich in nutritional ingredients, such as dietary fibers, polysaccharides, active polypeptides, the taro vinegar has the effects in seasoning and increasing appetite and also has a certain health protecting function. The types of vinegar products available in the market can be increased and the economic value of taro is improved. The taro vinegar is a novel and unique type of vinegar integrated with seasoning and health protection.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural products, in particular to taro vinegar and a production method thereof. Background technique [0002] Taro, also known as taro, is the tuber of taro, a plant of the family Araceae. my country is rich in taro resources and has a wide planting area. Taro is rich in nutrients, its main nutrient is starch, followed by protein, dietary fiber, fat, calcium, phosphorus, iron, potassium, magnesium, sodium, carotene, vitamin B 1 , Vitamin B 2 It is not only edible, but also has nutritional and health care functions, such as treating indigestion, pain, psoriasis, burns and other diseases. Taro starch has small particles and a delicate taste. It can be applied to baby food, clinical supplementary nutritional food, and can also be used as the main thickener and stabilizer for beverages such as fruit juice. Taro protein has a complete range of amino acids, reasonable composition an...
