PROBLEM TO BE SOLVED: To provide a method for controlling fermentation by simple inline measurement in fermentation process of culturing bacterium of the genus Lactobacillus or Bifidobacterium. SOLUTION: This method for controlling fermentation of a food to be fermented comprises measuring temperature and electroconductivity of a fermentation solution with time, obtaining electroconductivity compensated by temperature from these two factors i.e., temp. and electroconductivity, and controlling fermentation state of the fermentation solution by using the electroconductivity as index in a process producing fermented food by inoculating a microorganism such as lactic acid bacterium into a substrate containing a fermentation raw material and culturing the microorganism. Thereby, problems of a conventional method using electroconductivity as index are solved and fermentation step can simply be controlled in high accuracy. |
