Title:
PRODUCTION OF FERMENTATION LIQUOR CONTAINING GLUCONIC ACID AND ACETIC ACID
Document Type and Number:
Japanese Patent JP3603980
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently obtain a fermentation liquor of a vinegar, containing gluconic acid and acetic acid, good in flavor and useful for a food at a log cost by carrying out aeration culture of a bacterium of the genus Acetobacter under specific conditions.
SOLUTION: The aeration culture of a bacterium of the genus Acetobacter is carried out by regulating the average acetic acid concentration in a fermentation liquor at the time of stable fermentation to ≥0.2% (wt./vol.), preferably ≥1% (wt./vol.) and the average ethanol concentration to ≤0.2% (vol./vol.), preferably ≤0.1% (vol./vol.) to thereby produce a fermentation liquor containing ≥2% (wt./vol.), preferably ≥4% (wt./vol.) gluconic acid and acetic acid. The aeration culture is preferably the semicontinuous batch culture or continuous culture.
