Quality and safety should be considered in the selection of tea packaging materials

as a kind of food, tea must eliminate the pollution of packaging materials when packaging, so as to reduce the deterioration of products due to the impact of packaging. When packaging tea, we should consider the quality and safety of tea packaging materials

1. There are many commonly used tea packaging materials, such as paper, plastic film, metal, ceramics, etc. Some wood, bamboo and other materials can also be used for packaging. When choosing the packaging materials for tea, we should mainly start from the two aspects of economy and health, that is, when choosing the packaging materials, we should not only have a reasonable price, but also meet the relevant national health requirements, such as quality preservation, moisture-proof and moisture-proof, and at the same time, we should also consider preventing the entry of microorganisms

2. When choosing packaging materials, we should also prevent tea from aging and deterioration. Tea contains tea polyphenols, amino acids, tensile strength, constant elongation, constant elongation value, yield strength alkaloids earlier this year and other substances, which are easy to be affected by temperature, humidity, light and oxygen. These must be taken into account when choosing packaging materials. At the same time, tea polyphenols in tea are prone to oxidation and polymerization. When storing tea, we should avoid the oxidation of tea polyphenols, which will deteriorate the tea

3. The quality of tea is greatly affected by the environment, so the quality of tea packaging materials needs to be strictly controlled. First of all, we should pay attention to moisture-proof. Moisture proof is the key in tea packaging. Secondly, tea packaging should be protected from light. Light note accelerates the changes of various components in tea and destroys the quality of tea. Finally, the oxygen content in the environment is also an important factor in tea packaging, and its gas resistance should be considered when selecting packaging materials

the selection of tea packaging materials should fully consider its quality and safety according to the characteristics of tea and the principle of tea deterioration. Thus, the quality of tea can be preserved for a long time when it is packaged
