How to preserve the best tea leaves, how to preserve the best tea leaves

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.

Tea leaves can be stored for a long time according to the following methods.

First of all, the tea is sorted out, put it into a special aluminum foil bag for food, squeeze out the air in the bag, seal the tea bag, and after sealing, put the tea into the prepared tinplate can, cover the lid, and place the tea canister in the refrigerator and freezer at a temperature of 5.

2) Use refrigerator storage: To maintain the freshness and fragrance of tea, it is best to store at low temperature, especially the more delicate tea leaves such as Longjing, Biluochun, and Huangshan Maofeng should be refrigerated. It must be noted that the refrigerator that preserves tea must be hygienic, clean, and odorless, and cannot store anything other than tea.

4) Use jars for storage: first divide a small amount of tea leaves into small jars so that they can be used at any time, and the rest of the tea leaves are sealed and stored in large jars. It is best not to use glass jars, porcelain jars, wooden boxes, or medicine jars, because these utensils have the disadvantages of being light-transmitting, moisture-proof, and fragile.

The canned materials suitable for preservation are: Tin cans or iron cans: with the function of opacity, it is the most suitable material, and the cans are padded with a layer of cotton paper or kraft paper before packaging, and the cans must be kept clean, dry and odorless.

Tin cans: It is best to use a double-layer lid, and a layer of cotton paper or kraft paper should be lined in the can before packaging, and the gap between the lid can be sealed with adhesive tape. Sealed jars:

The sealed jars sold on the market are usually transparent, so it is best to pack the tea leaves in an aluminum foil bag before putting them into the sealed jar, and you can also put desiccant to strengthen the moisture-proof function.

If you want to drink fresh tea at any time, so that the tea leaves can maintain their original shape and taste as much as possible during the preservation period, then please be sure to keep the tea leaves in dry conditions, never keep them in humid conditions, never come into contact with items with peculiar smells, and avoid contact with air and direct sunlight. In the process of preservation, the tea should be squeezed as much as possible, so that the tea can maintain its original shape and essential color.

In the process of buying tea, we should choose good quality tea, and pay attention to the proper method of preservation in our own hands.

The tea leaves are sealed and packaged when they are bought back. These teas are fully packaged. If it is not opened, it can be stored in a dry place for half a year to a year without spoilage.

Here are some ways we can preserve the tea leaves that we have opened:

1.If possible, you can buy a small refrigerator for storing tea leaves, keep the temperature at minus 5 degrees Celsius, and open and close the seal tightly, and then put the tea leaves in the refrigerator. Or you can store the tea in the freezer of the household refrigerator, but you can't put other food and other things in the freezer.

2.Use a drying oven to store the tea leaves.

3.It is also a good idea to use clay pots to place tea leaves.

4.We can also only buy a small amount of tea at a time or buy small packages of tea leaves, which can effectively reduce the number of times the package is opened and prevent the tea leaves from being exposed to the air too much. This method can only ensure the quality of tea, and it is convenient to brew.

There are many types of tea, and the relatively suitable preservation methods are also different. Green tea is suitable for canned and sealed refrigeration; Black tea needs to be stored in an airtight dry container; Oolong tea can be stored at room temperature with double-lidded tea cans such as iron cans and tin cans.

White tea needs to be stored in tin cans and iron cans with good sealing; Pu'er tea is stored on cotton swab paper and in a odorless environment at room temperature. In short, the storage of tea should be done: anti-pressure, moisture-proof, sealed, protected from light, and anti-odor.

Improper storage of tea leaves will be subject to temperature and moisture, and even mold. At this time, the sun must not be used to re-dry, the tea after sun exposure will become bitter and unpalatable, and the high-grade tea will also become of inferior quality.

Tea leaves are generally stored in a cool, dry place, and then it is better to have a relatively good sealed jar.

The preservation of tea leaves is important, and here are some tips for preserving them:

1.Storage environment: Tea should be kept in a dry, cool, odorless place. Avoid places with direct sunlight, high temperatures, humidity, and excessive air circulation.

2.Container selection: The container in which the tea leaves are stored should be opaque and should be well sealed to avoid contact with the air, humidity, and odors.

3.Keep the original packaging: If the tea leaves are in the original packaging, try squeezing the air out and then resealing the bag.

4.Separate storage: If there is a large amount of tea leaves, you can consider dividing and preserving, only take one part at a time, and continue to keep the rest sealed.

5.Small amounts and multiple times: It is recommended to take out only the required amount of tea leaves during each brewing to avoid exposing the remaining tea leaves to the air for a long time.

6.Avoid odors: Tea leaves will absorb odors around you, so avoid odors from perfumes, cosmetics, etc.

Tea storage method: tea is a dry product, easy to absorb moisture and produce qualitative changes, it has a strong adsorption of water and peculiar smell, and the aroma is very volatile. When the tea is not stored properly, under the action of moisture, temperature and humidity, light, oxygen and other factors, it will cause adverse biochemical reactions and microbial activities, which will lead to changes in the quality of tea.

1. General storage method A small amount of tea is used at home, and it is generally used to store iron colored tea cans, tin bottles, colored glass bottles and ceramics. Among them, it is better to choose iron colored tea cans with double-layer lids and long-necked tin bottles, and to store tea leaves with ceramics, it is advisable to have a small mouth and a large belly. When using these containers to fill tea leaves, check that the containers are airtight, and that the tea leaves should be filled to the fullest, so as to minimize the air inside the containers.

Although this storage method is simple and easy to use, it is only suitable for short-term storage. 2. The use of quicklime storage method can delay the preservation time of tea to about one year. Lime is a kind of desiccant, when preserving tea with quicklime, the tea can be wrapped in thin kraft paper, bundled firmly, stacked in layers around the dry and odorless intact jar or rust-free, tasteless small iron barrel, put a bag or several bags of semi-weathered quicklime in the middle of the altar and the barrel, put several bags of tea leaves on it, and then plug the mouth of the altar with kraft paper, cover it above, put it in a dry place, generally change the lime once in 1 February, this method is not easy to be damp because the tea is not easy to be wet, so the preservation time is longer, as long as the lime is changed on time, The quality of tea is also not easy to change.

3. Use food bag storage method Use two new tasteless, non-porous plastic food bags, wrap the dry tea leaves with moisture-proof paper, put them into one of the bags, squeeze them gently, squeeze out the air in the bag, and then tie the bag mouth tightly with a rope, and then put the other bag in reverse on the outside of the first bag, after the air in the bag is squeezed out, then tie the bag mouth with a rope, and finally put it into a dry, tasteless, closed iron drum for storage. What role do antioxidants in tea play in food processing? A recent study by the Tea Research Institute of the Chinese Academy of Agricultural Sciences pointed out that for every 100 kilograms of Dalu tea, 4 kilograms of antioxidants can be extracted from it.

This antioxidant, when added to tea cola, peanut butter and instant noodles, can significantly extend the shelf life. This invention also solves a big problem of making moon cakes. Due to the high oil content of moon cakes, they are easy to dry and deteriorate.

Using the antioxidants extracted from this tea, the storage time of mooncakes can be extended from 40 days to 5 months.

Jar storage method: Fill the tea leaves into a tinplate tea jar with a double lid, preferably full without leaving a gap, so that there is less air in the jar. The double lid should be closed tightly, the gap of the lid should be glued with adhesive tape, and the tea can should be packed into two layers of nylon bags and the mouth of the bag should be sealed.

Thermos flask storage method: Put the tea leaves into a dry thermos flask, close the lid tightly, and seal the bottle mouth with white wax. Franco-Italian matters:

The water content of tea leaves in preservation should not exceed 5% (green tea) -7% (black tea), and the tea leaves can be fried or dried before being collected; The tools for roasting and roasting tea should be very clean, without a little grease or peculiar smell; And it should be slowly roasted with a simmer, and care should be taken to avoid the tea leaves being scorched and broken or contaminated by other peculiar smells. By the way, let's talk about the refrigerator specially suitable for storing tea: Haier's four-temperature zone refrigerator "0+007" refrigerator meets the conditions for storing tea.

According to reports, the unique ice temperature fresh-keeping room of this refrigerator can store tea for 1 to 2 months, and the soft freezer can be stored for 6 months, not only the color of the tea will not change, but also the sealed fruit and vegetable box also ensures the aroma of the tea, which can fundamentally solve the problem of difficult storage of tea. Now, Haier's four-temperature refrigerator has become a "treasure" for tea farmers. This refrigerator is especially suitable for the storage temperature of Longjing tea.

Tea has a shelf life, but it is related to the variety of tea, and the shelf life of different teas is also different. Like Yunnan's Pu'er tea and the brick tea of ethnic minorities, the aging is better, and the shelf life can reach 10 to 20 years. Another example is Wuyi rock tea, the next year old tea has a rich aroma and mellow taste; Hunan's black tea, Hubei's Fuzhuan tea, Guangxi's Liubao tea, etc., as long as they are stored properly, not only will not deteriorate, but can even improve the quality of tea.

In general, it is better to be fresh. Like green tea, the shelf life is generally about one year at room temperature. However, the main factors that affect the quality of tea are temperature, light, and humidity.

If stored properly, these factors are reduced or eliminated, and the tea leaves can last for a long time. To judge whether the tea is expired, there are mainly the following aspects: to see whether it is moldy or old; Whether the green tea turns red, and the soup color turns brown and dark; The concentration, astringency and freshness of the taste decrease, in addition to the shelf life on its packaging, and if it is a loose tea, it is best not to drink it for more than 18 months.

The tea we buy is basically 7 grams per brew of packaging, this tea packaging method uses vacuum compression packaging method, if it is such a package, and with the outer can packaging, if you will drink it in the near future (within 20 days), generally only need to be placed in a cool place, away from light preservation, if you want to achieve the best effect and the longest time limit for preserving Tieguanyin tea, it is recommended to keep it fresh at minus 5 degrees in the quick-freezer, so as to achieve the best effect.
