Abstract:

In order to accurately and quickly grasp the changes of the main parameters in the fermentation process of lactic acid bacteria, the changes in the number of viable cells, tail gas components, glucose and lactic acid in the lactic acid fermentation process were measured by KRH-BI0300 type fermentation tank control system, cell density monitoring system, SHP8400PM process gas mass spectrometry analyzer, biological sensor analyzer and other fermentation process analysis methods. The results show that the parameters of lactic acid bacteria fermentation process can be quickly and accurately grasped by a variety of modern analytical methods. This study laid the foundation for optimal control and lactic acid bacteria industrialization fermentation process.

Key words: detection method, process parameters, lactic acid bacteria fermentation
