What are the preservation methods of tea? The best way to preserve tea

Tea should be stored in a dry, dark, well-ventilated and cool space, and the utensils for storing tea should be sealed, and should not be stored together with items with peculiar smells (cosmetics, detergents, camphor essence, etc.), and different tea leaves should be stored separately, especially flower tea. It should be kept away from odorous and humid places such as operation rooms and toilets.

In addition, the dryness of the tea leaves is high, so it should be handled with care when taking and placing them.

The way to store tea is suitable for tea Pay attention to the problem Dedicated fresh-keeping cabinet to store green tea, lightly fermented, medium-fermented oolong tea When storing green tea, you can take the tin foil bag sealing method; When storing oolong tea, you can take the vacuum, tin foil bag sealing method Canned storage of black tea, Pu'er tea The utensils are mainly purple sand and ceramic products, and the utensils must be dry, odorless, and tight. When storing, the tea should be wrapped in rice paper and wrapped in leather paper on the outside. Put desiccant in the void of tea Barreling method Any tea can be made of paper, iron, pottery, and tin cans.

The barrel must be dry and odorless Vacuum packaging method is suitable for spherical and hemispherical oolong tea Be careful not to crush the tea leaves.

Tea should be protected from high temperatures:

Tea leaves are best stored at temperatures ranging from zero to five degrees. If the temperature is high, the sugars, amino acids, vitamins and aromatic substances in the tea will be decomposed and destroyed, and the quality and aroma of the tea will be reduced.

Tea should be protected from sunlight:

If the tea is exposed to sunlight for a long time, it will promote the pigments and esters of the tea. Oxidation, so that the tea phyll decomposes into demagnesium chlorophyll. Tea cannot be stored in glass containers, because stored in glass containers or transparent plastic bags, after being exposed to sunlight, its internal substances will have a chemical reaction, which will deteriorate the quality of green tea leaves.

Tea leaves cannot be exposed to oxygen for a long time:

Chlorophyll, vitamin C, esters, aldehydes, etc. in tea are easy to combine with oxygen in the air, and the oxidized green tea leaves will make the tea soup red and dark, so that the nutritional value is greatly reduced.

The space for storing tea leaves should not be too humid:

Because tea is a loose and porous hydrophilic substance, it has a strong ability to absorb moisture. When storing tea, the humidity is best at 60%, how to exceed 70% will be easy to mildew, acidification and deterioration due to moisture absorption.

In the hot summer, the container of tea should be placed in a cool place.

When preserving tea, it needs to be placed in a cool and ventilated place, and can also be placed in tea cans, cartons and refrigerators for preservation, but it should be noted that the tea needs to be sealed, because the tea leaves will affect its flavor and texture when it is damp, and the tea leaves put in the refrigerator are also easier to absorb other flavors, thus affecting the tea drinking experience.

Because tea has strong adsorption, it is easier to absorb the taste, so the tea should be stored in a odorless environment, and in the process of storing tea, the higher the humidity, moisture content and temperature of the environment, the greater the quality of the tea will be affected, so the tea needs to be kept in a dry environment, while avoiding sunlight and light.

Tea preservation methods.

1.Tea canisters:

You can put the good omen tea leaves in an aluminum foil bag and then put them in the tea cans for preservation, it should be noted that the tea cans containing the tea leaves must be placed in a cool and dry place.

2.Refrigerator Storage:

Refrigerator storage tea is more suitable for green tea, fragrant oolong tea and yellow tea, and at the same time, the tea stored in the refrigerator must be sealed, otherwise the tea will easily absorb the taste of other foods.

3.Three-layer packaging method:

The preservation of white tea can be done using the three-layer packaging method, with aluminum bags, plastic bags and corrugated boxes, so that the storage of white tea leaves can play a shading and light-proof effect, and at the same time, it can also ensure the normal aging of old white tea and do not absorb foreign gases.

Tea leaves in the refrigerator.

Because of its different characteristics, there are some varieties that are suitable for storage in the refrigerator, and other varieties need different preservation methods, green tea, oolong tea and Tieguanyin are more suitable for storage in the refrigerator, and black tea, Pu'er tea, traditional craft oolong tea, aged old tea and white tea are not suitable for storage in the refrigerator.

Tea leaves are kept fresh and stored.

When storing tea fresh, you can choose tea cans to preserve tea, pay attention not to use paper bags to dislike the tea leaves, because the paper will absorb moisture, which will shorten the shelf life of tea, so when choosing tea cans, try to choose jars with good sealing performance, which is conducive to isolating air and moisture, and effectively preventing tea celery socks from being damp.

It is best to use a drying oven to preserve the tea leaves. Because the temperature of the drying oven is stable and the air is also isolated, the tea leaves will not be damp or oxidized when stored in the drying oven.

Tea polyphenols, polyphenols, vitamin C and carotene in tea are highly oxidized, so ambient temperature, relative humidity, odor, light, air and microorganisms will affect the quality of tea. In order to keep it from deteriorating, it must be careful to avoid high temperature, high humidity, light and oxygen.

The materials used to preserve tea in daily life are aluminum-platinum composite bags, utensils, and a combination of the two. Tin pots are preferred, but other clay pots, metal boxes, etc. are also acceptable. It is best to put an appropriate amount of tea preservative in the packaging bag to preserve the tea leaves in a composite bag.

Of all the tea leaves, green tea is best stored in the refrigerator. If the storage time is short and you need to drink it at any time, you can put the green tea in the refrigerator and adjust the temperature of the refrigerator to about 5 degrees Celsius; However, if it is an unopened tea leaf and you want to keep it for more than a year, you should put it in the freezer.

In addition, in order to prevent tea from becoming the "deodorant" of the refrigerator, the tea should be sealed and packaged before being put into the refrigerator, and a sufficient amount of special preservative should be filled into the packaging bag, and the packaging material should be preferably an aluminum foil composite bag.

It should be noted that after taking out the tea leaves from the refrigerator, do not open the package immediately, the correct way is: take out the tea leaves in the refrigerator and let it slowly heat up, and after it rises to room temperature (usually every other day), open the packaging bag, and then brew and drink. And it is best to drink it in half a month.

Compared to green tea, oolong tea, black tea, and jasmine tea do not have to be stored in the refrigerator. Due to the relatively low content of polyphenols in oolong tea and black tea, the aging and deterioration rate is slower and easy to store. Flower tea has a strong floral aroma, and storage at low temperature will inhibit its aroma and reduce the freshness and concentration of the aroma.

Therefore, as long as it is placed in a dry, airtight, light-proof container and odor-free container, it can be stored for a long time. Pu-erh tea is best stored at room temperature and does not need to use desiccant.

1. The storage method of iron cans

Choose the best tinplate double-lid color tea on the market as a container. Before storage, check whether the body and lid of the can are closed and cannot leak. When stored, it will be dry. Tea cans, cans should be packed tightly. This method is convenient to use, but it is not suitable for long-term storage.

Second, the storage method of hot water bottles

Choose a warm thermos as containers. Fill the dried tea leaves into the bottle, fill them to minimize the amount of air retention, close the bottle with a cork, seal the edge with white wax, and then wrap it with adhesive tape. Due to the low amount of air in the bottle and the stable temperature, this method is also effective and easy to maintain.

3. Ceramic altar storage method

Choose a dry and odorless, airtight ceramic altar, wrap the tea leaves with kraft paper, place them around the altar, embed a lime bag in the middle, put the tea bag on it, fill the altar with cotton wrapping. Lime is replaced every 1-2 months. This method uses the hygroscopic properties of quicklime to make the tea not damp, the effect is better, and the quality of tea can be maintained for a long time, especially some precious teas such as Longjing and Dahongpao, which are particularly suitable for use.

Fourth, food bag storage method

First wrap the tea leaves with clean and odorless white paper, then wrap a piece of kraft paper, and then put it into a plastic food bag without pores, squeeze it gently, squeeze out the air in the bag, and then tie the bag with a thin soft rope to take a plastic food bag, put it on the outside of the first bag, squeeze it gently, squeeze the air in the bag tightly with a rope, and finally put it into a dry and odorless closed iron bucket.

5. Low-temperature storage method

Keep the tea storage environment below 5 degrees Celsius, that is, use cold storage or freezer to preserve the tea leaves.

Sixth, charcoal sealed storage method

Take advantage of charcoal's extremely moisture-absorbing properties to store tea. Burn the charcoal first, immediately cover it with a brazier or iron pot to extinguish it, and then wrap the charcoal in a clean cloth and place it in the middle of the clay pot containing the tea leaves. The charcoal in the cylinder should be replaced in time according to the situation of Hu Chao.
