Detection of the Yogurt Incubation Kinetics by Portable Impedance Converter

Abstract

Impedance microbiology based on AD5940 single-chip convertor measurement by gold interdigital electrodes could be a valuable method for tracking and control the yogurt fermentation process with portable sensor device. The results obtained are with a good agreement with pH kinetics measurement, which is a typical method for yogurt fermentation detection in the food industry.
