Abstract

The invention relates to the field of food analysis and quality research, in particular to a multi-parameter on-line monitoring device for fermentation process. The device is provided with an oxygen sensor, a carbon dioxide sensor, a flow sensor and an online monitoring system for detecting trace organic fermentation products such as alcohols, acids, aldehydes, esters and ethers in real time. A trace amount of organic fermentation products are detected by developing a fermentation gas production online detection method, and multi-scale parameter real-time online analysis in the fermentation process is realized in combination with conventional oxygen uptake rate (OUR), carbon dioxide generation rate (CER) and respiratory entropy (RQ). The device and the method have the remarkable advantages of high detection speed, high sensitivity, stable performance and the like, and can be widely applied to various fermentation production fields.

Description

technical field [0001] The invention relates to the field of food analysis and quality research, in particular to a device for on-line real-time monitoring of multi-parameters in a fermentation process. The device and method can analyze trace volatile organic fermentation products in real time and on-line in the fermentation process, and simultaneously detect multiple parameters such as oxygen consumption rate (OUR), carbon dioxide production rate (CER) and respiration entropy (RQ). Background technique [0002] The fermentation process is an ancient and young biochemical process, mainly through the growth and chemical changes of microorganisms to produce a large number of metabolites. The fermentation process is often complicated, and changes in fermentation conditions have a great impact on the yield and quality of fermentation products. In recent years, people pay more and more attention to food safety and quality inspection. The real-time on-line monitoring of state par...
