The latest course on banana storage and ripening techniques

Bananas are generally transported from growing places in the south to other areas where bananas do not produce bananas. They can only transport bananas whose peels are hard and not yet fully ripe, but cannot transport fully ripe bananas, because easily ripe bananas are not resistant to storage and are easy to rot. They may rot on the way of transportation, so they need to be ripened when they are sold to the destination. During storage and ripening, there are certain stress and methods. The main purpose of this article is to introduce the process of storage and ripening.

1. Storage temperature

The most suitable temperature for banana transportation and storage is 13 degrees. No matter how high or low it is, it is not very good. The high temperature is easy to rot and blacken, and finally it is impossible to eat. The low temperature below 11 degrees is easy to produce frost injury. After freezing damage, the fruit hardens inside, and it is not easy to ripen. Because bananas are tropical fruits, it is necessary to maintain the most suitable temperature.

2. Storage method

Transport in a car that can adjust the temperature. after the car is cleaned, the bananas are packed in boxes and adjusted to 13 degrees. After being transported to the destination, you can immediately put them in the basement or in a temperature-controlled storeroom. If the indoor space is large, do not stack it, it can be dispersed, and the small space can be placed at the bottom of the basket against the bottom of the basket, because the bottom of the banana basket is smaller than the cover of the basket, so there will be some gaps and ventilation, which is beneficial to storage and does not go bad easily.

3. Ripening humidity and temperature

When promoting red, you need to maintain a certain humidity and temperature in order to promote ripening well. generally, the ripening humidity is maintained at 85% to 90%. The humidity below 80% affects the ripening effect, which may not be very good. The most direct way to keep moisturizing is to spray water regularly and maintain humidity all the time. You can use a sprayer to spray water, which is easy to absorb and more uniform. Keep the ripening temperature at 20 to 22 degrees, not too high or too low.

4. Methods of accelerating ripening

It is necessary to control the temperature at the beginning of ripening, and when the temperature rises, it can be cooled by spraying water or ventilation. If there is a temperature control condition, it is easier to control. If the temperature is too high, the banana softens quickly, but the chlorophyll does not disappear, and the fruit is a soft green fruit that cannot be sold. You can't ripen if the humidity is too low. The method of accelerating ripening is mainly ethylene gas inflation. 40% of the test spirit is sprayed evenly with a sprayer according to the concentration of 1500 × 10 ~ 6, completely stacked together, and then covered with plastic sheet. after sealing, the ripening will be completed in about three days.

Bananas must be stored at a temperature of 13 degrees, ripening must be maintained at 20 to 22 degrees, and humidity must be more than 80% to ripen well. The ripening method is mainly accelerated by spraying ethylene seal. There are some small details to pay attention to, so it's best to follow the procedure.
