Embodiment 1

[0019] Embodiment 1: Winter jujube ozone ice film storage and preservation method

[0020] 1. Harvesting of fruits: Harvest at the right time, and strictly avoid any scars on the fruits during harvesting.

[0021] 2. Grading: Classify according to the diameter of the fruit.

[0022] 3. Pre-cooling: Put the fruit in a -2°C cold storage for 24 hours, and the fruit temperature is basically the same as that of the cold storage.

[0023] 4. Fruit ozone ice film storage and preservation:

[0024] Soak the fruit in ozone water with a water temperature of 0°C and an ozone concentration of 2 mg / L for 1 min. The soaked fruit is placed in a cold storage at -2°C, and the relative humidity of the cold storage is >90%. During storage and preservation, in order to maintain the effect of ice film storage and preservation, when the ice film area on the surface of the fruit is less than 30%, it can be soaked in low-temperature ozone water again.

Abstract

The invention relates to a method for storing and refreshing fruits. The method for storing and refreshing fruits through an ozone ice film provided by the invention is as follows: based on the storing environment below 0DEG C, a manual ice film containing ozone gas is formed on the surfaces of the fruits through an ozone water soaking method, the ice film not only can inhibit the transpiration and water loss of the surfaces of the fruits and can prevent the occurrence of damage caused by low temperature and freeze injury, but also can kill the various types of microorganism on the surfaces of the fruits, oxidize the substances released by the fruits, such as ethylene, ethanol and the like, and delay the after-ripening process of the fruits. By using the method provided by the invention, the fruit storing refreshment time is prolonged, and the refreshing effect is improved.

Description

technical field [0001] The invention belongs to a method for storing and preserving agricultural products, in particular to a method for storing and preserving fruits. Background technique [0002] my country is a big fruit producing country. In 2009, the fruit output exceeded 200 million tons, ranking among the top in the world. However, due to the backward storage and preservation methods and the primitive storage and consumption methods, the loss rate of fruits in my country's logistics links such as picking, transportation, and storage is about 12%. According to statistics, there are 24 million tons of fruits that rot and deteriorate after harvest in my country every year, with a total value of 48 billion yuan. At present, there are many methods and technologies for fruit storage and preservation at home and abroad, but the basic principle is to regulate the three key elements that play a key role in the preservation quality. The first is to control its aging process, wh...
