Method for reducing sugar concentration in vegetable or fruit juice, and method for producing lactic acid bacteria-containing vegetable or fruit juice using the method

摘要

PROBLEM TO BE SOLVED: To provide a vegetable or fruit juice imparted with high added value while reducing the sugar concentration thereof.SOLUTION: Provided is a method for reducing the sugar concentration in a vegetable or fruit juice comprising: the following steps (1) and (2): the step (1) where the pH of a vegetable or fruit juice is controlled to 5 to 9; and the step (2) where lactic acid bacterium is added to the vegetable or fruit juice obtained in the step (1), the lactic acid bacterium is propagated to reduce the sugar concentration in the vegetable or fruit juice by lactic acid fermentation, and further, its pH is reduced with lactic acid produced by the lactic acid bacterium.SELECTED DRAWING: Figure 1
