As a modern technology, physical sterilization has been gradually used extensively in food industry.

Some varieties of cold sterilization technology,for example physical sterilization,chemical sterilization and sterilization of natural biocide,in the processing of fruit and vegetable juice were briefly introduced.

Study on the drying characteristics and sterilization mechanism in adsorption drying system;

In this paper,the recent progress in nano-TiO2 photocatalytic technique at home and abroad is introduced,including the mechanism of photocatalytic reaction,its sterilization mechanism and its toxicology.

Objective To study the germicidal mechanism of propolis-silver ion compound nanometer emulsion.

Objective To study the germicidal mechanism of chlorine dioxide with Escherichia coli as the experimental object.

In order to observe the killing effect of ortho-phthalaldehyde (OPA) on Candida albicans and to explore its germicidal mechanism, suspension quantitative germicidal test and transmission electronmicroscopic technique were used for the study.

Progress in preparation and sterilizing mechanism of electrolyzed oxidizing water;

niger and Staphylococcus aureus were carried out using as-synthesized nano-MgO samples and the bactericidal mechanism was also investigated.
