How to keep longan fresh?

Longan is a common fruit, which we often call laurel. It has high nutritional value. If you want to preserve it for a long time, you can seal it with plastic wrap and put it in the refrigerator. Under normal circumstances, it can be stored for 5-8 days. If it is longer, the taste will be affected. If the humidity is relatively high, it can be stored for 10-15 days. If you apply a layer of preservative, it can be stored for about 40 days.

1. Storage method of fresh longan

1. Seal fresh longan in a plastic bag and put it in the refrigerator. Do not put it in the freezer of the refrigerator, but in the refrigerator. That's all. Remember to eat fresh longan as soon as possible to prevent it from spoiling.

2. You can dry the fresh longan and preserve it. Dried longan can be preserved for a longer time and has a unique flavor.

3. Dried longans should be placed in a box, covered with plastic, and then placed in a cool place. Check them frequently to prevent mold, insect infestation, etc.

2. How long can fresh longan be kept?

Fresh longan can be kept fresh for 5-8 days when stored at room temperature. At 3-5 degrees, after 40 days of preservation, the good fruit rate reaches 96%. The longan fruit is crystal clear, rich in nutrients, with fresh flesh, sweet juice and pleasant flavor. However, longan is harvested and matured under high temperature and high humidity conditions from August to September. The living fruits undergo dramatic physiological and biochemical changes. The fresh fruits are prone to discoloration and deterioration, and are not resistant to long-distance transportation and long-term storage. At room temperature of 28℃, all the fruits will generally spoil and rot within a week. Suitable low temperature conditions can prolong the storage period of longan. Generally, it can be kept fresh for 10-15 days under the conditions of 2-3℃ and relative humidity of 90%-95%. The storage effect is better if certain chemical treatments are used and combined with atmosphere control factors. After 40 days of storage, the fruit is still fresh in color, high in quality and good in flavor. Therefore, the key to storing and preserving longan lies in antiseptic treatment, sterilization and prevention of physiological decay.
