A Detailed Guide to the Latest Methods for Preserving and Storing Wax Apple
Wax apple is a relatively rare fruit nowadays, but it also has a certain market in our country. At present, there is also a certain planting area in our country. The wax apple has a large growth volume, so its yield is also relatively high. After the wax apple is harvested, preservation and storage work needs to be done well, otherwise the fruit is prone to spoilage and rotting. So how should it be stored? Below, the editor brings you the preservation and storage methods for wax apple. Let's take a look together!
1. Low-temperature storage
The most commonly used storage method for wax apple is low-temperature storage. In a low-temperature environment, the respiration of the fruit will be inhibited, allowing the original quality of the wax apple to be maintained as much as possible. When carrying out low-temperature storage, the temperature should be controlled at around 10 degrees. Low-temperature storage can reduce the weight loss rate of the fruit and ensure that the fruit will not depreciate due to environmental factors. It delays the time of fruit aging and ripening. Generally, the wax apple fruit can be directly wrapped in plastic wrap and then stored at a temperature of 10 degrees, and the storage time can reach about one month.
2. Ultraviolet treatment
After the wax apple is harvested, using ultraviolet irradiation on the fruit can eliminate bacteria on the surface, preventing bacteria from invading the fruit through the skin. It prevents the fruit from rotting and improves the lifespan of the harvested wax apple. Moreover, under appropriate irradiation, a thin film can form on the surface of the wax apple fruit, reducing water loss. Irradiate with ultraviolet light for about two minutes each day, and continuously turn the fruit during irradiation to ensure even irradiation. After irradiation, place it at room temperature for storage. After one week, the good fruit rate can still reach 100%, but the fresh-keeping period is only about 12 days.
3. Controlled atmosphere storage
Controlled atmosphere storage is achieved by reducing the oxygen content in the air and increasing the carbon dioxide concentration. While ensuring that the fruit can carry out normal life activities, it can reduce the respiration of the fruit, achieving the purpose of inhibiting microbial activity. It prevents the fruit from metabolizing too quickly, speeds up aging, reduces losses during storage, and improves the fruit's preservation time. During controlled atmosphere storage, the nitrogen content in the air should be maintained at around 85%, oxygen at 5%, and carbon dioxide controlled at around 10%. Pay attention to ventilating once every day, which can delay fruit ripening by 2-3 weeks.
4. Ozone storage
Ozone storage is also a commonly used storage method for wax apple fruit. Ozone can play a role in disinfection and sterilization and in removing harmful gases and toxins. Moreover, it will not cause pollution to the fruit itself. In a cold storage room, inject ozone into it. Keep the number of injections at about 5 times per day, then ventilate for 10 minutes. It can significantly slow down the time of fruit ripening and the loss of nutrients, improving freshness retention.
The above is a brief introduction to the preservation and storage methods for wax apple. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
