The latest fresh-keeping and Storage methods of Lotus Fruit

Lotus is a rare fruit now, but it also has a certain market in our country. Now in our country, there is also a certain planting area, the growth of lotus flower is large, so the yield is also relatively high. And lotus fog needs to do a good job of preservation and storage after picking, otherwise the fruit is easy to deteriorate and rot. So how do you store it? The following editor has brought you the fresh-keeping and storage methods of lotus fog, let's take a look at it!

1. Low temperature storage

The most commonly used storage method of lotus flower is low temperature storage. In the low temperature environment, the respiration of the fruit will be inhibited, and the original quality of lotus flower can be maintained as far as possible. When storing at low temperature, the temperature should be controlled at about 10 degrees. Low temperature storage can reduce the weight loss rate of fruit and ensure that the fruit will not be devalued by environmental factors. To delay the time of fruit senescence and ripening, the lotus fruit is generally directly wrapped in practical plastic film and stored at a temperature of 10 degrees, and the storage time can reach about one month.

2. Ultraviolet treatment

After the lotus fog harvest, ultraviolet radiation can destroy the bacteria on the surface of the fruit and prevent bacteria from invading the fruit from the epidermis. Prevent fruit rot and improve the life span of lotus harvest. And under proper irradiation, a thin film can be formed on the surface of lotus fruit to reduce water loss. Ultraviolet rays are exposed for about two minutes every day, and the fruit should be turned over constantly during the irradiation to ensure uniform irradiation. After irradiation, it is stored at room temperature for a week, and the good fruit rate can still reach 100%, but the shelf life is only about 12 days.

3. Controlled atmosphere storage

Controlled atmosphere storage is to increase the concentration of carbon dioxide by reducing the content of oxygen in the air. While ensuring the normal life activities of the fruit, it can reduce the respiration of the fruit and achieve the purpose of inhibiting the activity of microorganisms. Prevent the fruit from metabolizing too fast, accelerate the aging, reduce the loss of the fruit during storage, and improve the insurance time of the fruit. During controlled atmosphere storage, the nitrogen content in the air is kept at about 85%, oxygen is 5%, and carbon dioxide is controlled at about 10%. Pay attention to a change of air every day, which can delay the fruit ripening time for 2-3 weeks.

4. Ozone storage

Ozone storage is also a common storage method of lotus fruit. Ozone can play the role of disinfection and sterilization, removal of harmful gases and toxins. Moreover, it will not cause pollution to the fruit itself, so ozone is injected into the cold storage. Keep the number of injections at about 5 times a day, and then ventilate for 10 minutes. It can obviously slow down the time of fruit ripening and the loss of nutrients, and improve the degree of freshness.

The above is a brief introduction to the fresh-keeping and storage methods of lotus fog. That's all for today's introduction. This article is for reference only. I hope I can help you reach it.
