LACTIC ACID-FERMENTED FUNCTIONAL FOOD AND METHOD FOR PRODUCING LACTIC ACID-FERMENTED FUNCTIONAL FOOD

摘要

PROBLEM TO BE SOLVED: To inexpensively produce lactic acid by using sugarcane as a raw material.;SOLUTION: Sucrose is incroporated in a solution prepared by diluting a squeezed liquid of sugarcane with water. The sucrose is hydrolyzed to generate glucose and fructose by mixing a malted rice made from Aspergillus oryzae to the solution and carrying out digesting treatment at room temperature for about 1 month or more. Lactic acid fermentation is then carried out at room temperature for about 1 month or more by mixing a previously cultured solution of Lactobacillus. Fructose-1,6-diphosphate, 3-phosphoglyceraldehyde, 1,3- phosphoglycerate and pyroracemic acid (pyruvic acid) are sequentially generated from the glucose and fructose by the action of Lactobacillus. Lactic acid is further generated from the pyruvic acid by the lactic acid fermentation. The solution in which the lactic acid is generated is then divided into suitable containers and stored at a dark cold place.;COPYRIGHT: (C)2002,JPO
