Does tea need to be kept in the refrigerator?

Question 1: Tea should be stored in the refrigerator. Different teas have different storage requirements. The following is an introduction to the storage methods of several types of tea.

Dahongpao: room temperature, sealed, no vacuum.

Pu'er (raw, cooked): normal temperature, ventilated, no odor, protected from light, annual average humidity below 65%.

Tieguanyin, black tea: sealed, vacuumed, long-term storage between 0 degrees and -5 degrees (short-term storage can be placed in the refrigerator).

Green tea (Longjing, Houkui, Biluochun, etc.): sealed, not vacuumed, stored at about 0 degrees for a long time (short-term storage can be placed in the refrigerator), green tea placed in the freezer or freezer should be Take it out in about half a month and put it directly in the refrigerator for 1-2 days before returning it to the freezer or freezer. This will help keep the green tea fresh.

Scented tea: It is not recommended to store it for a long time. It is better to buy it as you drink it. For short-term storage, it can be sealed and placed in the refrigerator.

All cold-stored tea leaves should be taken out three or four hours in advance and gradually heated up before brewing, so as to ensure the taste of the brewed tea soup. Therefore, when each type of tea is stored in cold storage, it should be divided into large and small bags based on one or two per half a catty. This way, there is no need to take out all the tea leaves to heat up when needed, which is conducive to long-term storage.

Question 2: Can tea be stored in the refrigerator? Hello!

Can be stored in the freezer! Refrigerator storage method:

Put it in the refrigerator and store it at low temperature. If the temperature is controlled below 5℃, the quality of the tea will be better preserved, and the flavor of the tea can generally be maintained for more than 1 year. If it has been packaged in small cans, cans, tubes, or boxes, it generally has better airtightness. As long as it is wrapped in a clean plastic bag, it can be stored directly in the refrigerator. For loose tea, you can first put it into a clean, clean, odorless brown bottle or tinplate can or tube, fill it firmly, cover it tightly, seal it with tape and melt wax, then put a plastic bag on the outside and tie it up. Store in refrigerator.

Question 3: Can tea be stored in the refrigerator? Of course you can, but it also depends on what kind of tea it is. Dahongpao and Pu'er cannot be placed in the refrigerator, but Tieguanyin must be placed in the refrigerator. Storing tea in the refrigerator or freezing is much better than storing it at room temperature, but it must be noted that the tea must be sealed in a food-grade packaging bag with good airtightness to prevent odor transfer and moisture. It is best to refrigerate in small packages, and then take out a small bag after drinking to avoid repeated storage and withdrawal from the refrigerator. Do not rush to open the packaging bag of tea leaves that have just been taken out of the refrigerator. Wait until the tea leaves return to room temperature before opening the bag. This can prevent water vapor in the air from condensing on the cold tea leaves and causing moisture and deterioration.

Question 4: Which teas do not need to be stored in the refrigerator. Except for relatively green tea, green tea, and fragrant Tieguanyin, which need to be stored in the refrigerator, other teas do not need to be stored in the refrigerator.

Question 5: Why should tea be kept refrigerated? For a person who loves tea, it is essential to know how to preserve tea. Because if good quality tea leaves are not properly preserved, they will quickly deteriorate, become dark in color, lose their aroma, taste bad, or even become moldy and unfit for drinking.

Reasons for tea deterioration: The main reasons for the deterioration of tea quality are moisture and odor infection. The finished tea is highly hygroscopic and can easily absorb moisture from the air. According to experiments, if quite dry tea leaves are placed indoors, after one day, the water content of the tea sea can reach about 7%; after five or six days of being left exposed, the water content rises to more than 15%. In rainy weather, the moisture content increases by 1% for every hour of exposure. In seasons when the temperature is high and suitable for microbial activity, when the water content of tea leaves exceeds 10%, the tea leaves will become moldy and lose their drinking value (can moldy and spoiled tea leaves be used?).

In terms of odor infection, tea contains terpene compounds and high-molecular palmitic acid, which can quickly absorb the odor of other substances and change or cover up the original smell of tea. For example, if you put tea leaves together with camphor balls, spices, medicines, etc., or put tea leaves in new woodware or lacquerware with a strong smell, you will be infected with the smell of these things after a few hours. If it is unpleasant, it will not be drinkable if it is severe.

In addition, light also affects the quality of tea. Especially if the tea leaves are left under strong light for too long, it will easily destroy the chlorophyll, causing the tea leaves to become yellowish and dark, and the quality will deteriorate. At the same time, if the tea is exposed to the sun, it will produce a sun-dried smell, making it difficult to drink.

Methods for preserving tea leaves: In order to prevent the tea leaves from absorbing moisture and odor, reduce the impact of light and temperature, avoid crushing and breaking, and damaging the beautiful appearance of the tea leaves, proper preservation methods must be adopted.

Warehouses for storing large quantities of tea should be designed and constructed according to the reasons for tea deterioration; while small batches of tea can be preserved using quicklime or charcoal.

This method of preserving quicklime or charcoal is to prepare a ceramic jar (or use a tinplate bucket). The size depends on the number of tea leaves to be preserved. It must be dry, clean, odorless, and rust-free; put the unweathered quicklime blocks into a fine cloth bag. , each bag weighs about half a kilogram; the tea leaves are wrapped in clean tissue paper, each bag weighs half a kilogram, tied tightly with a string, and placed layer by layer around the altar, leaving a space in the center for a bag of quicklime. Put another bag of tea leaves on top. If it is not full, you can add one or two more layers in sequence. Then use cowhide to block only the mouth of the jar, and cover it with a straw mat or brown mat. This way, quicklime can absorb the moisture in the tea leaves and the air. , to keep the tea leaves fully dry. Quicklime must be replaced in time after absorbing moisture and weathering. Generally, it must be replaced one month after the jar is installed, and then every one or two months. If the charcoal absorbs moisture, burn the charcoal red first, cool it and then put it into cloth bags. Each bag weighs about one kilogram. The charcoal should be taken out and burned every two months before use.

Generally, tea drinkers or families purchase a small amount of tea, so there is no need to store it in jars. They can be put into tinplate tea cans with double-layer lids. It is best to fill them up without leaving any gaps. There is less air in the jar, which is conducive to preservation. The double-layer lids should be tightly closed, and the gaps between the lids should be sealed with tape, and the tea can should be put into the two-layer nylon bag, and the mouth of the bag should be airtight. Another way is to put the tea leaves into a dry thermos bottle and close the lid tightly. Seal the bottle mouth with white wax. By adopting these two methods, the quality of tea can be maintained for a longer period of time. (For the convenience of drinking, you can use the tea box to hold less tea leaves, and be sure to close the lid tightly after each use; green tea is easily affected by light and is not suitable for preservation in glass bottles.)

We can also use vacuum How to preserve inflatables. The vacuum preservation method is to put the tea leaves into a tinplate can, weld the joints, and use an air pump to pump out the air in the can to create a vacuum. The air-filled preservation method is to fill aluminum foil bags containing tea with highly purified inert gas. Using these two preservation methods, the original color, aroma, and taste of tea can still be maintained if it is stored at room temperature for more than one year; if it is stored at low temperature, the effect is better. Things to note when preserving are that the moisture content of tea leaves during preservation cannot exceed 5% (green tea) to 7% (black tea). If the moisture content of the tea leaves exceeds this standard before storage, it must be fried or dried first. , and then in the collection. The tools for frying and baking tea should be very clean, without any grease or odor; and they should be baked slowly over a slow fire, and great care should be taken to prevent the tea leaves from being scorched and broken, so as to prevent the smell of charcoal smoke or other odors from contaminating the tea leaves.

Question 6: How to store Tieguanyin tea? Does it need to be placed in the refrigerator? It is suggested that the poster should not put the tea in the refrigerator, but just put it in a dry environment to avoid exposure to the sun

Generally speaking, there are several ways to preserve tea: I hope this can help you

< p> 1. Storage method of plastic bags and aluminum foil bags: It is best to choose plastic bags with seals and used for food. It is better to use plastic bags with high density and high density. Do not use plastic bags that have smell or are remade. After filling the tea, the air in the bag should be squeezed out as much as possible. It would be better if a second plastic bag can be put on the opposite side. The tea in a transparent plastic bag will not be easily exposed to sunlight. The principle of packaging tea in aluminum foil bags is similar to that of plastic bags. In addition, the purchased tea is packaged in separate bags, sealed and placed in the refrigerator, and then brewed in batches to reduce the chance of tea leaves coming into contact with air after opening and delay quality deterioration.

2. Metal can storage method: You can choose iron cans, stainless steel cans or dense tin cans. If it is a newly purchased can, or a can that has been used to store other items and has left a smell, you can first Put a little tea powder into the jar, cover it with a lid, shake it up and down and gently rub the wall of the jar before discarding to remove the odor. There are stainless steel tea cans with two-layer lids on the market, which are simple and practical. It would be better if the tea can be packed in a clean and odorless plastic bag, then placed in the can and covered with a lid, and the lid can be sealed with tape. Metal cans containing tea should be placed in a cool place, away from direct sunlight, smelly, humid, or heat sources. This will prevent the cans from rusting and slow down the aging and deterioration of the tea. In addition, the tin can material is dense and has good effects on moisture-proof, oxidation-proof, light-blocking and odor-proofing. 3. Low-temperature storage method: Keep the tea storage environment below 5 degrees Celsius, that is, use a refrigerator or freezer to preserve tea. When using this method, please note: For storage periods within six months, the refrigeration temperature should be maintained at 0 to 5 degrees Celsius. The most economical and effective; if the storage period exceeds half a year, freezing (-10 to -18 degrees Celsius) is better. It is best to store in a dedicated refrigerated (freezer) warehouse. If it must be refrigerated (frozen) together with other foods, the tea should be properly packaged and completely sealed to avoid absorbing odors. The air circulation in the refrigerated (frozen) warehouse is good and the cooling effect has been achieved. When purchasing a large amount of tea at one time, you should first pack it into small bags (cans) and then put it into the refrigerated (frozen) warehouse. Take out the required brewing amount each time. It is not advisable to freeze and thaw the same bag of tea repeatedly. When taking out tea leaves from a refrigerated (freezer) warehouse, you should first allow the temperature of the tea leaves in the tea can to rise to approximately room temperature before taking out the tea leaves. If you do not open the tea can immediately, the water vapor in the tea leaves will easily condense and increase the water content, causing the tea to not be fully brewed. Tea accelerates deterioration. Long-term storage and processing methods of tea: The moisture content of tea should be controlled at 3-5% for long-term storage. The degree of roasting and drying has a very important relationship with the storage period of tea. Generally speaking, the roasting is heavier and the moisture content is higher. The lower one can be stored for a longer period of time. 4. When the optimal storage period of tea has expired, it should be taken out and then roasted.

You can wash the rice cooker until it is odorless, wipe it dry, pour the tea leaves on a porcelain plate or tin foil paper and place it in the rice cooker. Turn the switch to the [Keep Warm] position, cover the pot lid half-closed, and stir it in time. In about half a day, the tea leaves will be The stale taste changes to a clear and ripe aroma. It is suitable to crush it with your thumb. After cooling down, it can be packaged and stored again. Some people use microwave ovens to dry and roast tea leaves. However, the heating time is short, the oven door is closed tightly, or it is difficult to control. This often results in the surface of the tea leaves being carbonized or the stale smell cannot escape. This shortcoming is still to be overcome technically. The safest way is to ask a familiar tea master or tea farmer to roast the collected tea leaves.

Question 7: Why should good tea leaves be placed in the refrigerator? , under chemical inducements, it is easy to produce chemical changes, which is commonly known as tea change. Poor storage conditions for tea will accelerate its own oxidation and mildew. The best containers for storing tea are tin bottles, porcelain jars, and colored glass bottles. Secondly, it is advisable to use iron cans, wooden boxes, bamboo boxes, etc. Bamboo boxes are not suitable for use in the dry north. Plastic bags and cartons are the worst. The container in which tea is stored should be dry, clean, and free of odor. Stored tea leaves should be placed in a dry and ventilated place. Do not place it in humid, high temperature, unclean or exposed places. There should be no strong-smelling items such as camphor, medicines, cosmetics, cigarettes, detergents, etc. around. Also note that different types and grades of tea cannot be mixed and stored together. Do not use quicklime as a hygroscopic agent when preserving black tea and scented tea. Logically speaking, it should not be placed in the refrigerator, as it will get damp in the refrigerator

Question 8: Should tea be placed in the freezer compartment of the refrigerator or refrigerated? Tea purchased from the market must be stored properly if it is not in use temporarily. Storage and preservation is the same even for small packaged tea packaged in cartons and tea packaged in tins. Because they are not completely airtight, they can easily deteriorate if stored for a long time. Tea has the characteristics of liking warmth and dryness but hating cold and dampness, liking clear mint but hating steaming and stuffiness, and liking clear turbidity but hating fragrance and smell. Therefore, there are certain requirements for the container and method to be used when storing tea. No matter which method is used to store tea, the packaging material must be odor-free and have good moisture-proof properties. The tea container and use method must be as airtight as possible to reduce contact with air. The storage place must be dry, clean, and free of moisture. Odor. There are some methods for storing tea at home.

(1) General storage method: A small amount of tea is used at home, and it is generally customary to store it in iron colored tea cans, tin bottles, colored glass bottles and ceramic containers. Among them, iron colored tea cans with double-layer lids should be used. Tea cans and long-necked tin bottles as well. It is better to use ceramic containers to store tea, which is suitable for those with large mouths and small abdomens. When using the above container to hold tea leaves, you should first check whether the container is airtight, and fill the tea leaves fully to minimize the amount of air in the container. Although this method of storing tea is simple and easy to use, it is only suitable for short-term storage, usually a few months, because it cannot be completely sealed.

(2) Use desiccant storage: Using desiccant can extend the storage time of tea to about one year. The type of desiccant selected depends on the type of tea and the convenience of obtaining materials. To store green tea, you can use lumpy undeliquesced lime; to store black tea and scented tea, you can use dry charcoal; if conditions permit, you can also use discolored silica gel.

When using quicklime to preserve tea, you can first wrap the loose tea in thin kraft paper (a few to half a catty into a bag), tie it tightly, and place it in layers in a dry, tasteless and intact jar or jar. Around a rust-free and odorless small-mouth iron cylinder, place one or several bags of unweathered quicklime between the jar and the cylinder, and put a few small bags of tea leaves on top. Then use kraft paper and cotton pads to block the mouth of the jar or cylinder, then close the lid tightly and place it Store in a dry place. Generally, the lime is replaced once every 1-2 months. As long as the lime is replaced on time, the tea will not absorb moisture and deteriorate. The charcoal tea storage method is similar to the quicklime method and will not be described in detail.

The tea storage method using color-changing silica gel desiccant has better moisture-proof effect. The storage method is similar to the quicklime and charcoal method, but this method is more effective. Generally, the tea leaves will still maintain their freshness after half a year of storage. Color-changing silica gel is blue before absorbing moisture. When the desiccant particles change from blue to translucent pink, it means that the absorbed moisture has reached a saturated state. At this time, it must be taken out and baked or placed on a low fire. Dry in the sun until the original color is restored, and then you can continue to use it.

(3) Refrigerator storage method: Store in the refrigerator at low temperature. If the temperature is controlled below 5°C, the quality of the tea will be better preserved, and the flavor of the tea can generally be maintained for more than one year. If it has been packaged in small cans, cans, tubes, or boxes, it generally has better airtightness. As long as it is wrapped in a clean plastic bag, it can be stored directly in the refrigerator. For loose tea, you can first put it into a clean, clean, odorless brown bottle or tinplate can or tube, fill it firmly, cover it tightly, seal it with tape and melt wax, then put a plastic bag on the outside and tie it up. Store in refrigerator.

(4) Thermos bottle storage method: Thermos bottles and thermos flasks with good thermal insulation properties can be used to store tea. The effect is good and can generally maintain the color, fragrance and flavor of tea for up to 1 year. Put the loose tea leaves into a new thermos bottle or thermos flask, fill it fully to minimize the amount of air retained in the bottle, cover it tightly with a cork, and seal it with white wax.

(5) Food bag storage method: Use two new, odorless, non-porous plastic food bags, wrap the dry tea leaves in moisture-proof paper, put them into one of the bags, and gently store them. Squeeze gently to expel as much air as possible from the bag, tie the mouth of the bag tightly and then put the seal downwards, then put it into another plastic bag, remove the air, and tie the mouth of the bag tightly. This kind of packaging can also have a certain preservation effect when stored alone. If it is stored in a dry, odorless, airtight iron cylinder, the tea preservation effect and duration will be longer and better.

Tin bottles, porcelain jars, and colored glass bottles are the best containers for storing tea. Secondly, it is advisable to use iron cans, wooden boxes, bamboo boxes, etc. Bamboo boxes are not suitable for use in the dry north. Plastic bags and cartons are the worst. The container in which tea is stored should be dry, clean, and free of odor. The prepared tea should be placed in a dry and ventilated place, and should not be placed in a humid, high temperature, unclean or exposed place. The place where tea is stored should not contain camphor, medicines, cosmetics, cigarettes, detergents and other items with strong odors. Also note that tea leaves of different types and levels cannot be mixed and stored together, nor can they be stored raw... >>

Question 9: Of course you don’t need to put all the tea leaves in the refrigerator, but you also need to Depending on the type of tea, Dahongpao and Pu'er cannot be placed in the refrigerator, but Tieguanyin must be placed in the refrigerator. Storing tea in the refrigerator or freezing is much better than storing it at room temperature, but it must be noted that the tea must be sealed in a food-grade packaging bag with good airtightness to prevent odor transfer and moisture. It is best to refrigerate in small packages, and then take out a small bag after drinking to avoid repeated storage and withdrawal from the refrigerator. Do not rush to open the packaging bag of tea leaves that have just been taken out of the refrigerator. Wait until the tea leaves return to room temperature before opening the bag. This can prevent water vapor in the air from condensing on the cold tea leaves and causing moisture and deterioration.

Question 10: Why should tea be placed in the refrigerator? Tea leaves are required to be dry and refrigerated. They will not get damp when placed in the refrigerator. The tea leaves from our factory need to be refrigerated every time they are transported, and they are also refrigerated in the refrigerator when they arrive at the teahouse
