Method for producing fermentation liquor containing short-chain fatty acids

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fermentation liquor containing colloidal particles having a particle size not exceeding 50 nm and short chain fatty acids and having an acidity of pH 3 or more and 4 or less. SOLUTION: A multi-stage fermentation process is equipped with a fermentation apparatus including a plurality of sets of temperature-controlled fermentation vessels 10, soft water w serving as a starter, and NPMD containing sporulated Clostridium spp. The original bacterial solution b composed of 7 kinds of fermenting bacteria of the deposit number NITEp-02945 to NITEp-02951 registered in the above, and the first medium of the dried soybean ds which is a natural material and the dried plants such as turmeric, beetle, turmeric. The multi-stage fermentation process is carried out using three types of fermentation medium produced by separately fermenting the second medium of the mixed medium pm2 and the third medium of the honey raw material pm3.
