Over-packaging of tea is a hot topic in recent years. Tea has a long history in China. The story of the detoxification of tea in the Three Emperors and Five Emperors era is widely circulated. As an important member of the present gift, tea has become a secret weapon for merchants. Since last year, we have strictly investigated the excessive packaging of tea and solved the packaging problem of tea.
Tea is now widely consumed by people. Depending on the efficacy of various teas, the types of products vary, and the storage environment and conditions are different. --dy23wl How to store tea? We have a coup. Tea contains a large number of amino acids, sugars, polyphenols, vitamins, aromatic substances and other nutrients, which are green health drinks, but the preservation of tea is affected by many factors, such as sunlight, temperature, moisture, air and so on.
1. Direct sunlight will destroy the vitamin C in the tea and change the color and taste of the tea, so the tea must be stored in an opaque container.
2. When the temperature rises, the speed of the chemical reaction will increase, which will promote the decomposition of the active ingredients of the tea and reduce the nutritional value of the tea. Therefore, tea leaves should be kept at a low temperature.
3. The presence of water is a necessary condition for the decomposition of many organic substances, and it is also a necessary condition for bacterial activity. Therefore, if the moisture of the tea leaves is too large, not only the tea leaves are prone to loss of nutrition, but also easily mildewed and deteriorated. Therefore, tea must be stored dry.
4. Tea leaves are in direct contact with the air and are easily oxidized by oxygen in the air; they lose their original flavor, so the container of tea leaves should be sealed. The modern tea industry chain is getting stronger and stronger, and the tea production in China is also increasing. In order to facilitate transportation and storage, vacuum packaging has become the best choice. The following introduces a tea vacuum packaging machine: DT300 vacuum packaging machine, which uses plastic composite film or plastic aluminum foil composite film as packaging material, and adopts microcomputer controller to control the whole process with high vacuum.
