How to store fresh pineapples, how to store fresh pineapples

Jackfruit is relatively large, the largest can reach more than 20 kilograms, and the small ones are about 5 kilograms, so few people can eat a whole jackfruit at one time. So how do you save jackfruit if you can't finish it? Not many people in the north may know about this problem, which is related to the main production area of jackfruit.

In fact, jackfruit is similar to other fruits, and it can be stored in the refrigerator if you can't finish eating, but it should not be stored for too long.

Jackfruit is rich in sugars, proteins, B vitamins (B1, B2, B6), vitamin C, minerals, fatty oils, etc. Its main substance is a substance called jackfruit protein that can be extracted from jackfruit juice and peel. The sugars, proteins, fats, oils, minerals and vitamins in jackfruit play a role in maintaining the normal physiological functions of the body.

Jackfruit. How to preserve the shelled jackfruit.

1. The preservation method of the refrigerator at home:

Put the skin in the refrigerator, seal the safety film, it is best to eat it within 5 days, and it is best to throw it away if you can't eat it after 5 days, it will ferment. Be sure to put it in the refrigerator, otherwise it will really stink. The refrigerator plays a big role in the summer, because there is a lot of food in the refrigerator, and it is necessary to pay attention to frequent disinfection in the summer to ensure health.

2. The preservation method of the family without a refrigerator:

Storage method: wrapped in a basket, lined with banana leaves or bamboo leaves, shredded paper. Store in a cool and ventilated place, under the conditions of temperature 11 13 degrees Celsius and humidity 85 95%, it can be stored for more than a month.

3. Process into dried jackfruit.

The jackfruit that can't be eaten can also be directly processed into dried fruits, with an oven or microwave oven, slowly roasted over low heat, turned over halfway, and gradually dried water, so that the processed jackfruit can be dried for a long time.

How to preserve jackfruit.

Jackfruit pulp can be frozen, and freezing will not affect its taste, but it is best to seal it with plastic wrap or a crisper box before freezing, so as not to stain the taste of other items in the refrigerator on the jackfruit, especially to be stored separately from seafood and river fresh food, in addition, the jackfruit can also be processed into dried fruits, with an oven or microwave oven, slow roasting over low heat, turning over halfway, and gradually drying the water, so that the processed jackfruit can be dried for a long time, but in order to prevent it from getting damp, It still has to be sealed in a plastic bag or crisper box, refrigerated or frozen.

How to store pineapple for a long time.

I'm in the fruit business, and the pineapple I bought back was black-hearted within a few days, I don't know what the problem is, if it's a storage problem, please specialist, dizzy, not eat it yourself, I am? How to store fresh pineapple without black hearts.

Causes of pineapple black heart:

Pineapple belongs to tropical fruits, if not stored properly, pineapple will suffer from rotten heart, the phenomenon of blackening in the middle, pineapple rotten heart disease, also known as black rot, soft rot or fruit rot, is one of the main diseases of pineapple fruit after harvest, caused by fungi. As a result, storage and transportation at room temperature are easy to rot, soften, and blacken due to black rot.

Sogou asked. Here are a few ways to store pineapples for a long time:

1.If you don't want to eat the pineapples you bought for the time being, you can try to keep them fresh by placing them in a basket or similar ventilated container, preferably with some bamboo leaves or shredded paper. Then store it in a cool and ventilated place, the recommended temperature is around 11-13 degrees Celsius.

Since the pineapple has not been cut, it can be stored for a longer time according to this method.

2.Leftover pineapples are comparatively more difficult to preserve because the pineapples have been peeled and the flesh is in direct contact with the air. To prevent the pineapple from spoiling, we can soak the pineapple whole in salted water, which can not only block the contact between the pineapple and the air, but also enhance the taste of the pineapple, which is really a double win.

3.The low-temperature storage method mainly inhibits respiration by lowering the temperature to achieve the purpose of storage and preservation. The response of pineapple fruit to storage temperature is related to the ripeness of pineapple fruit, if the whole green fruit without a little yellow at harvest is stored at a temperature of 10, it is very easy to produce chilling injury.

According to the results of the Hawaii test in the United States, the maximum storage life at 7 is four weeks, and the recommended storage and transportation temperature in India is 8, and South Africa recommends it.

4.Controlled atmosphere storage method is mainly to inhibit respiration by reducing the oxygen content in the storage reservoir and appropriate low temperature to achieve the purpose of preservation. According to a study by the University of Hawaii in the United States, a modified atmosphere composed of 2% oxygen and 98% nitrogen can extend the shelf life of pineapples at temperature.

Place in the refrigerator or soak in salt water.

If it is a whole pineapple, put the pineapple in a cool and ventilated container, preferably with a little shredded paper in the container, and then control the temperature to about 11 to 13 degrees.

If it's a pineapple that's already been cut, consider soaking the pineapple in salted water, which not only keeps the flesh of the pineapple out of the air, but also enhances the taste and texture of the pineapple.

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.

Dear, just put it in salt water. 1: Prepare a clean basin with water in it.

2: After the water is ready, add 2 tablespoons of salt, as much water as possible to cover the pineapple. 3:

Pineapples can be stored in salted water for up to 24 hours. [Happy] [Happy] [Happy].

Questions. Thank you!

Dear, you are polite, I wish you a happy life. [Happy] [Happy] [Happy].

There are two ways to keep pineapples fresh:

1. Uncut pineapple.

The storage time of such pineapples is relatively long, put the pineapples in a cool and ventilated container, and it is best to spread some shredded paper in the container, and then control the temperature to about 11-13, so that the pineapple can be stored for a longer time, provided that the pineapple is intact and has no wounds.

2. Peeled pineapple.

Consider soaking the pineapple in salted water, which not only insulates the flesh of the pineapple from the air, but also enhances the taste and texture of the pineapple. If you want to leave it overnight, it is best to seal the cut pineapple with plastic wrap and store it in the refrigerator, which not only keeps out the air, but also prevents the smell from carrying over.

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.

First of all, it is necessary to avoid long-term and large-scale contact between the flesh of the pineapple and the air, which is easy to deteriorate, so when preserving the pineapple, you can consider soaking the pineapple in salt water, which can not only isolate the flesh of the pineapple from the air, but also enhance the taste and texture of the pineapple.

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 held and rolled in the fresh-keeping or modified atmosphere storage;

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.

If it is a whole pineapple, put it in a cool and ventilated container, and then spread some shredded paper, and the temperature is controlled to about 11 to 13 degrees, which can be stored for a long time. If it is a pineapple that has been cut, to avoid long-term and large-scale contact between the flesh of the pineapple and the air, you can soak the pineapple in salt water to isolate the flesh of the pineapple from the air, and also enhance the taste and texture of the pineapple. <
