Rapid evaluation of Pixian Douban meju in the tank fermentor Based on the image features and multi-model analysis.

Pixian Douban (PXDB) meju is a crucial intermediate product in the PXDB production. In this study, a machine vision system was employed to monitor and evaluate the meju quality quickly to replace the time-consuming chemical methods. The results of correlation analysis indicated that the physicochemical indicators were highly related to the color changes.
