(one)Understand the characteristics of the food itself and determine the protection conditions it requiresTo do a good job in food packaging bags, you should first understand the main components, characteristics of food and the internal reactions that may occur in the process of processing and storage, transportation and circulation, including non-biological intrinsic biochemical reactions and biological spoilage reaction mechanisms, and secondly, the impact should be studied. The main components of food, especially the sensitive factors of nutrients such as fat, protein, and vitamins, including light, oxygen, temperature, microorganisms, physics, mechanical mechanics and other factors. Only by mastering the biological factors of the packaged food and determining the required protection conditions, can the correct selection of packaging materials and packaging technology be made (two)Research and master the packaging performance, scope of application and conditions of packaging materialsThere are many kinds of packaging materials with different performances. Therefore, only by understanding the packaging performance of various packaging materials and containers can we choose products that can not only protect the flavor and quality of food, but also reflect its commodity value and make comprehensive Packaging materials with reasonable cost. For example, high temperature sterilized food should be packaged with high temperature resistant packaging materials, while low temperature refrigerated food should be packaged with low temperature resistant materials.
