Here's how to store pineapples:

1. Store in a cool and ventilated place.

When buying pineapple, the preservation method is very simple, you can't put it in the sun, you should put it in a cool and ventilated place, you can wrap newspaper on its outer layer, and then put it on the ground to avoid damage to the skin, and it can be stored for more than ten days without deterioration.

2. Peel the pineapple and store it in the refrigerator.

Usually, many pineapples can't be eaten at one time after peeling, so you should take a clean plastic wrap to wrap the pineapple, and then store it in the refrigerator, so that the pineapple can be stored for two or three days after peeling.

3. Peel the pineapple and store it in salt water.

When you usually eat pineapple, remove the skin, you can soak it in salt water and eat it directly, if you can't eat it all at once, you can let the pineapple flesh soak it directly in salt water, which can prolong the preservation time of pineapple, let it be stored for 20 hours, and it will not deteriorate for 48 hours, but its preservation time should not exceed 20 hours, otherwise the taste will deteriorate.

4. Make pineapple sauce.

Pineapple contains sugars and acids, and the taste is sweet and sour, and it is also very good to eat as jam.

5. Make dried pineapple.

Pineapples are rich in nutrients, so they should be eaten immediately after opening, and pineapples that cannot be eaten temporarily can be dried by a drying machine, which can reduce the moisture in the pineapple, thereby reducing the chance of bacterial contamination and extending the shelf life.

Pineapple preservation methods: room temperature storage, low temperature storage, cold storage storage;

Store at room temperature: Post-harvest pineapples can be stored at room temperature, the storage warehouse requires fresh air, does not contain other chemical smoke, doors and windows are intact, not exposed to the sun and rain, and equipped with exhaust fans. The storage life is short, generally only 7 to 10 days;

Store at low temperatures: The low-temperature storage of pineapples after harvest needs to be cooled and stored and preserved, and the pineapples in the cooling stage must be cooled within 24 hours after harvest.

The storage and preservation phase, after the end of the cooling phase. The suitable temperature for low-temperature storage of pineapple is that this temperature environment can inhibit the occurrence of spoilage, reduce rot and prolong the storage life. Because low temperature can cause black heart disease, the method of dipping fruit wax is often used to reduce the occurrence of black heart disease.

Cold storage storage:Pineapples can be placed in a crisper or modified atmosphere store;

Fresh-keeping warehouse:The temperature of the fresh-keeping warehouse is set to 8-10, and the relative humidity is controlled at 85-95%, and the pineapple is stored for about 11-17 days under this condition;

Modified Atmosphere Library:The temperature of the controlled atmosphere storage is set to 7, the relative humidity is controlled at 85%, and the concentration of oxygen and carbon dioxide is suitable, and the storage period of pineapple can be as long as 2 months under this condition.

Timely harvesting: The fruit should be harvested in the early morning on a sunny day after the dew has dried. Do not harvest on rainy days to avoid rotting.

Post-harvest processing of pineapples: After the pineapple fruits are picked manually or mechanically, steps such as quality classification, size grading, sterilization, and loading in cardboard boxes are required. In order to avoid sunburn of pineapple fruits ripening in summer, shade the fruit with straw in the field, or bandage the pineapple leaves underneath the fruit to cover the fruit.

Sterilization and waxing treatment: The sterilization work is completed 6 hours after harvest.

How to save pineapple:

1. Generally speaking, pineapples that can't be eaten can be kept fresh for about two days in the refrigerator, and if you find a sour or other peculiar smell for more than two days, please don't eat it. Whole pineapples can be stored for up to half a month when the temperature is suitable.

2. Put the pineapple in the refrigerator, which should be placed in the vegetable and fruit trough above 7 degrees Celsius, and the storage time should not exceed two days. Pineapple, like apple, is very easy to oxidize after cutting, so it is recommended to eat as much as you want and cut as much as you want, and it is best to eat it all at once. If you really can't finish it and are afraid of turning black and wasting, you can cut it into small pieces, add sugar and marinate, rinse it or eat it as a dessert.

3. If it is an unpeeled pineapple, it can generally be stored for several days, and if it is peeled, it is as easy to spoil as an apple that has been knocked out. As soon as the pulp comes into contact with air, it is oxidized.

Pineapple Nutritional Value:

Pineapple is rich in nutritional value, in addition to reducing sugar, sucrose, glucose, protein, fat, crude fiber and organic acids, it also contains essential vitamins A, B, C, CAROTENE, THIAMINE, NIACIN and other vitamins. In particular, vitamin C content is the highest. and trace elements such as calcium, iron, magnesium, potassium, sodium, and phosphorus that are easily absorbed by the human body.

at room temperature. Pineapple is sweet and acidic, belongs to a tropical fruit, at room temperature it is easy to react with bacteria and microorganisms in the air and cause deterioration, it is generally recommended that pineapples at room temperature should be placed in a dry and ventilated place for preservation, so that pineapples can be preserved for a long time.

under the refrigerator. Under the low temperature conditions of the refrigerator, it can help inhibit the growth of bacteria and microorganisms in the pineapple, thereby prolonging the shelf life of the pineapple to a certain extent, so if you want to put the pineapple for a longer time, you can put the pineapple in the refrigerator for preservation.

How long do pineapples last in the refrigerator.

Intact. For the intact Polo, it has the protection of the outer skin and can be stored for a long period of time, under normal circumstances, as long as the pineapple is not damaged or squeezed, then it can be stored for about 7-15 days without deterioration.

Cut open. The cut pineapple will be stored for a relatively short period of time, because the nutrients in the pineapple are easy to react with the oxygen in the air and cause deterioration, so it is generally recommended to store it in the refrigerator for about 1-2 days.

This can usually be stored directly in the refrigerator, so I think it may be more convenient to store this way, and it will not change the taste overall.

How to preserve unpeeled pineapples: Place the pineapples in a basket or similar ventilated container, preferably with bamboo leaves or shredded paper. Then store it in a cool, ventilated place.

Pineapple is normal under normal temperature conditions, and the normal freshness time is about 7-10 days, and the quality is better;

Here's how to store pineapples:

Like mango and banana, pineapple is more sensitive to low temperatures, and pineapple is a non-breathing peak fruit. The storability of pineapple fruit is closely related to the harvest maturity, and the higher the ripeness, the worse the storage capacity of pineapple. Unripe fruits lack the flavor of the fruit.

8. Pineapples that are about ripe are suitable for storage and transportation. The temperature of pineapple chilling is below 7 degrees Celsius, and the symptoms of chilling damage are: the color of the fruit is dark, the flesh is water-stained, and the heart of the fruit turns black.

The suitable conditions for pineapple storage and transportation are; The temperature is about 10 degrees Celsius, the relative humidity is 85% 95%, and the storage period of different varieties can reach 2 to 4 weeks. Storage under the condition of controlled atmosphere with an oxygen content of 2% at 7 degrees Celsius can inhibit mold and achieve the best preservation effect.

Low-temperature storage Because low temperature can cause pineapple black heart disease, it is common to use the method of dipping fruit wax (fruit wax: water is 1 4) to reduce the occurrence of black heart disease. Wax-soaked pineapples can be stored for more than 3 weeks at a temperature of about 10 and a relative humidity of 90 °C.

Refrigerated pineapples for long-distance shipment must be refrigerated trucks or ventilated pre-cooling chambers within 24 hours of harvest. The time interval from harvest to refrigeration shall not exceed 48 hours under any circumstances. Post-harvest pineapples in the cooling phase of refrigerated pineapples (including refrigerated transportation) should be cooled down as soon as possible.

The refrigeration capacity of the cold storage should reach 800-930w power per ton of pineapple, the temperature control should be achieved, the air circulation ratio should be 80-100, and the air should be changed once every 1-2h. The storage temperature preservation stage is at the end of the cooling stage, and the temperature control reaches the cold point (and starts at a constant temperature, at which time the relative humidity should be 90%; The air circulation ratio can be reduced by half compared to the cooling phase, and the air can be changed at the right time.

If you don't rush to eat the pineapple, don't peel it first, and the unpeeled pineapple is generally stored in a cool place at room temperature.

Peeled pineapples need to be placed in the refrigerator and wrapped in plastic wrap, refrigerated, and slightly soaked in salted water before eating.

Peeled pineapples should not be kept for more than two days, especially pineapples that have been soaked in salted water should be eaten within one day.

1. If it is a freshly picked tree pineapple, you can use banana leaves or eggplant shredded paper and other materials to pad it in a basket, put the tree pineapple in it, and put it in a cool and cool Danian ventilation place, so that it can be stored for more than a month.

2. If you buy pineapples outside, you should also store them in a cool place. If it has already been cut, it is best to eat it as soon as possible when it has the best texture and taste.

Put ripe apples, ripe Fengliang imitation bananas, ripe small pineapples in the right way, just around the side, in the cool silver fiber place is generally ripe in a week. Do not seal it, otherwise it will not be cooked, and it will rot, because the water vapor produced by the heat of the pineapple cannot be evaporated. Remember to turn over every day, otherwise the bottom tissue is prone to rot due to long-term squeezing.

Don't expose it to the sun for a long time, the skin is tanned, the meat inside is not cooked, and it will rot in a few days.

If the skin is not ripe, the skin is soft and close to ripe, and the skin is hard and must be raw. Smell the skin with your nose, and if there is a little fragrance, it means that it is cooked, and it will not be very sweet, but it will be crispy. If the fragrance has a high taste of honey, it will be ripe through, it will be very sweet and sweet, but it will not be crispy, and it will be sweet and crispy when frozen in the refrigerator.

The pineapples sold on the street are all picked when they are very raw, and they are ripened with chemical agents, which is not delicious. It will be delicious if it gives off a little fragrance on the tree, even though the skin is green. When picking pineapples, tap them with a small stick, and the sound is often not natural and not ripe, such as fluttering sounds.

If the sound is dull, such as the sound of a skin, it can be cooked naturally.

Leave the pineapple overnight without soaking in water. Try not to soak pineapples in salt water overnight, pineapples contain a lot of sugar, sugar is easily soluble in water, and some nutrients will be lost. It will also promote the growth of bacteria overnight, which can easily cause diarrhea, abdominal pain and other physical discomfort symptoms after eating, and soft foam will also affect the taste of food, so try not to soak pineapple in water overnight.

If you can't finish it, you can wrap it in plastic wrap, put it in the refrigerator, and eat it in 2-3 days.

How to save pineapple:1. There is no way to cut the pineapple.

That is, just bought back, or a whole whole, no peeling and no cutting pineapple, such a pineapple storage time is relatively long, put the pineapple in a cool and ventilated container, in the container is best to spread some shredded paper, and then the temperature is controlled about 11 to 13, this preservation method can make the pineapple keep for a longer time, provided that the pineapple is intact and there is no wound.

2. How to preserve pineapples that have been peeled.
