Embodiment
[0047] The markers used in the embodiments of the present invention are freshly baked steamed buns in the market, with a moisture content of 20-30 wt%. Other markers that meet the requirements of the present invention can also be used, and here only steamed buns are taken as an example, which does not represent a limitation of the present invention.
[0048] The material to be tested is an anti-mildew sheet. Cut the polyethylene film into 24 x 10 cm sheets and make bags with a size of 12 x 10 cm open on one side for use as external airtight bags.

The invention provides a method for testing the microorganism inhibiting performance of a material. The method comprises the following steps: (1) selecting a marker; (2) adhering and sealing the marker and a to-be-tested material; (3) performing storage under the temperature and humidity suitable for microorganism growth; and (4) recording the size and number of bacterial plaques.
Description
technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a method for testing the performance of materials for inhibiting microorganisms. Background technique [0002] The existing technologies and methods for verifying whether materials have the effect of inhibiting microorganisms have the problems of difficult operation by non-professionals, long detection time, easy contamination and untruthful testing process. [0003] Existing technologies and methods for verifying whether materials have the effect of inhibiting microorganisms are the method of detection of the zone of inhibition and the total number of colonies. Bacterial inhibition zone test is a method that uses the diffusion of the sample to be tested in the agar plate to inhibit the growth of microorganisms around it to form a transparent circle, and judges the antimicrobial effect of the sample to be tested according to the size of the inhibition zone. This m...
