Packaging film for food storage containers, we focus on its security problem is often. Has a large amount of invisible microbes in the air, if the packaging container sterilization effect is not obvious or improper protection may cause secondary pollution, finally people eat the contaminated food may vomit, sick, etc. So how to sterilization to truly effective and ensure food safety? In the process of sterilization, we are going to consider what problem? Common, vacuum high-temperature cooking sterilization method can effectively kill more than 99% of the bacteria, but is only applicable to the palate, and will not change form after heated products. Roll of film is usually packing products such as candy, biscuit, coffee powder. Can't be using high temperature sterilization. After heated will lead to product shape and taste changes, from product sales. In order to effective sterilization and sharp retained products taste, we usually adopt two kinds of ozone sterilization and ultraviolet sterilization. Ozone sterilization: is a kind of strong oxidizer, sterilization process is a biochemical oxidation reaction. Ozone first role in cell membrane, the membrane component damaged, and lead to metabolic disorders, ozone continue to permeate through the membrane, and the damage of membrane lipoprotein and lipopolysaccharide, change the permeability of the cell, and led to the dissolution and cell death. Use ozone water disinfection sterilization technologies such as production equipment combined with membrane separation technology, aseptic filling system, etc. , in the brewing industry used in the production of soy sauce, vinegar and wine, can improve the quality and grade of the product. Ultraviolet sterilization: uv sterilization is the use of uv wavelength damages the DNA in bacterial virus ( Deoxyribonucleic acid) Or RNA ( Ribonucleic acid) The molecular structure of growing cell death and cause ( Or) Regenerative cell death, to achieve the effect of sterilization. Ultraviolet germicidal effect is stronger, but for the objects of the penetration ability is very weak. Combined ultraviolet sterilization of penetration ability is poor, cost and approximately equal to the ozone sterilization, recommended bare ozone sterilization method, the purpose is to increase the contact area, so as to achieve better sterilization effect.
