This is the most common way to preserve tea in the family. Can choose iron cans, stainless steel cans or tin cans. If it is a new jar, first put a little tea powder in the jar, cover it, shake it up and down, then pour it out to remove the odor. Tea pots containing tea leaves should be placed in a cool place, not in places with direct sunlight, peculiar smell, humidity and heat source, so as to slow down the aging and deterioration of tea leaves.
Food bag storage method
Choose two thick, high-density food bags, put the tea in the first food bag, then squeeze out the air, and then use the second food bag to cover it upside down. You can also wrap the tea in clean and odorless kraft paper first, and then put it in a food bag to seal it. If possible, it can also be placed in a sealed, dry and tasteless tin can or stainless steel tea can, and the effect is better.
Hot bottle storage method
Tea leaves are stored in thermos bottles and thermos bottles with good thermal insulation performance, and the effect is good. The method is to put the sun-dried tea leaves into a dry thermos bottle, fill it with tea leaves to reduce the amount of air left in the bottle, then cover it tightly with a cork and seal it with a layer of white wax around the cork.
Refrigerator storage method
Studies show that the best effect of tea preservation is to keep the environmental temperature of tea storage below 5℃. Families and courts can put tea in food bags or tea cans, seal them, put them in refrigerators, or use special refrigerators for preservation. But be careful not to mix it with other foods, so as to avoid tea absorbing odor.
Desiccant storage method
Using desiccant can prolong the storage time of tea to about one year. The type of desiccant may depend on the type of tea. To store green tea, you can use large pieces of deliquescent lime; Black tea and scented tea can be stored with dry charcoal; If conditions permit, color-changing silica gel can also be used.
Introduction of matters needing attention in tea storage
1, avoid high temperature. At high temperature, tea leaves are prone to browning. With the increase of temperature, amino acids, sugars, vitamins and aromatic substances in tea will be decomposed and destroyed to varying degrees, which will reduce the quality, aroma and taste. Different teas have different requirements for temperature, so consumers should consult clearly when buying tea.
2. Avoid dampness. Tea is a porous and hydrophilic plant. Under humid conditions, tea leaves can easily absorb moisture in the air and become mildewed and deteriorated, so tea leaves must be stored under dry conditions.
3. Avoid the sun. Under strong sunlight, chlorophyll and alcohol in tea will be oxidized and decomposed, which will affect the quality of tea and even lose its drinking value.
4, avoid odor. All tea leaves are forbidden to be mixed with smelly things. The special substances contained in tea make it easy for tea to absorb the surrounding odor. If it is mixed with other products, it will lead to the inability to remove other odors in tea and make tea lose its original fragrance.
