According to the mold and yeast count limit value of the sample, dilute the sample by the corresponding multiple, and add the sample diluent into the mold and yeast test bottle. If the sample diluent contains mold and yeast, CO2, the metabolite of the growth and reproduction of mold and yeast, can cause the test The color of the bottom of the bottle changes from green to yellow. The color change process is monitored in real time by the detector of the microbial rapid detection system, indicating that there is contamination of mold or yeast in the sample; conversely, if there is no contamination of mold or yeast in the sample diluent, the color change process at the bottom of the bottle is monitored. The color remains unchanged, indicating that the sample meets the limit value of the relevant standard.
