Vegetable protein fermentation Lactic acid bacteria beverage
Abstract：Plant protein lactic acid bacteria fermentation beverage is to provide people with a large number of high quality protein, is healthy, convenient, delicious and stylish characteristics of the combination of lactic acid bacteria beverage. In this paper, the processing technology and formula of lactic acid bacteria beverage of vegetable protein were optimized, and the stability of the products was studied. By using single factor and orthogonal experiment, the optimum process and formula of the plant protein lactic acid bacteria fermentation beverage were determined by sensory evaluation,. The best conditions for the vegetable protein fermentation of lactic acid bacteria beverage: Flour 0.4%, 1.6% of whole milk powder, alpha amylase 0.00075%, saccharifying enzyme 0.00105%. 7% sucrose, citric acid 0.03%, CMC-Na0.1%, 0.15% guar gum, and flavor of the products reached the city sold product requirements.
