Edible fruit and vegetable preservative A translucent emulsion formulated with sucrose, starch, fatty acids and polyesters. It can be applied to the surfaces of tomatoes, eggplants, citrus and apples by spraying, brushing or dipping. The freshness can reach over 200 days. . This preservative can be eaten with fruit. High-temperature treatment preservation method Britain has invented a variety of high temperature storage technology for bulb vegetables. This technology uses high temperature to inhibit the germination of bulbous vegetables, the storage room temperature is controlled at 23 °C, relative humidity is maintained at 75%, to achieve long-term storage and preservation purposes. New plastic preservation method Japan developed a new one-time plastic cling film consisting of two translucent translucent nylon membranes with high osmosis sugar syrup between the two layers. The packaging of fruits and vegetables with this plastic film can slowly absorb moisture that has exuded from the surfaces of fruits and vegetables, thereby achieving the purpose of preservation. Decompression treatment The low pressure of the preservation chamber is generated by pumping out indoor air by a vacuum pump. The low pressure is controlled below 100 mmHg and the minimum is 8 mmHg. The relative humidity in the air is controlled by a humidifier installed in the room, which is generally more than 90%. The method reduces the oxygen content in the room during the evacuation, maintains the respiration of the fruits and vegetables at a minimum level, and also eliminates part of the indoor carbon dioxide and ethylene gas, which is favorable for long-term storage of fruits and vegetables.
