Formulation 1 potassium sulfite 97%, starch or gelatin 10%, calcium stearate 1%. The above raw materials were pulverized and mixed, and a small amount of water was added to prepare a tablet of 0.5 g. Disperse the agent in a container of fruit, and add 40 preservative tablets to 8 kg of fruit. This preservative can keep apples, citrus and other fresh-keeping for half a year, the loss rate is less than 5%, and it will not pollute the fruit. The cost of each preservative is only 1 cent.
Formulation 2 100 parts of aqueous substance, 0.05 to 5 parts of surfactant, 0.01 to 2 parts of aqueous polymer compound, 50 to 500 parts of water, and mixed at room temperature to make it an emulsion, in the range of 100 to 150 Sterilize at °C for 5 to 30 minutes. A thin layer of water is applied to the surface of the fruit to be cooled. Due to the isolation and bactericidal action of the film, the fruit can be preserved. This agent is used for eggs, the dosage can be larger, the polymer compound is more and the water can be less; when used for vegetables, the water can be more, the polymer compound and the water-based substance are less. This method is mostly used for apples, peaches and other fruits and various eggs and roots, tubers, solanaceous fruits and other vegetables, which can improve the storage life of fruits by 5 to 7 times.
