Because tea at high temperature is easy to accelerate the speed of oxidation or aging, it is suitable to be stored in a well-ventilated and cool place, such a preservation method can slow down the speed of automatic oxidation. The study found that if the temperature is controlled below 5℃, the effect of preserving the tea quality will be better. Therefore, refrigerator storage has become one of the commonly used tea in ordinary families.
Ice essence has excellent thermal insulation and can maintain a constant low temperature. It not only meets the characteristics of low temperature for tea storage, but also can preserve the quality of tea leaves. Therefore, leaving the tea in it is a good choice. First of all, we can use the tea in small packaging form, into iron, tin containers or ice bottles sealed, and then put a plastic bag for moisture-proof, and then put it in the refrigerator storage. If the temperature is controlled below 5℃, the tea leaves will not deteriorate for more than a year. If it is stored in the spring, the color, aroma and taste of the tea are basically unchanged in the winter. This method is simple and easy to use. Pay attention to the storage of tea with special refrigerator best, avoid with other food to avoid tea adsorption odor.
So How to store the tea leaves in a refrigerator?
Refrigerator storage method is simple and feasible, but there are also situations to pay attention to:
(1) Because the tea is easy to absorb moisture and odor, and the interior of the refrigerator is wet, all kinds of food placed will affect the taste of the tea. In order to prevent the tea from becoming the "deodorant" of the refrigerator, the tea must be sealed before the refrigerator, and put sufficient amount of special preservative in the packaging bag.
(2) After taking out the tea leaves from the refrigerator, the package should not be opened immediately, but the tea leaves should heat up slowly. When the temperature rises to room temperature, open the bag, and then brew and drink. And after taking it out from the refrigerator, it is best to drink it in half a month.
(3) Of all the tea types, green tea is best stored in the refrigerator. Other tea types, such as black tea, oolong tea, Pu'er tea and scented tea, do not need to be kept in the refrigerator. Because the content of polyphenols in black tea and oolong tea is relatively low, the speed of aging and deterioration is slow, which is easy to store. Pu 'er tea is fermented tea, which contains beneficial bacteria and enzymes, which can make the taste of Pu' er better and more fragrant. And enzyme to play a role, you need ventilated, cool, dry environment, but put in the refrigerator can not meet the needs of enzyme, so only ordinary storage method is good.scented tea has a fragrant aroma. If it is stored at low temperature, the aroma will often be suppressed, reducing the freshness and concentration of the tea itself. So as long as it is kept in a dark, dry, sealed, tasteless container.
Because technology is more and more developed, there are refrigerators and freezers in the market, and some also include 0℃ ice temperature area, so this is undoubtedly the best news for tea friends.
