I. Ethylene absorbent
Ethylene absorbent can inhibit breathing and prevent aging. Mainly composed of vermiculite, pumice, bentonite, calcium peroxide, aluminum, silicate or iron, zinc and other potassium permanganate carriers mixed with potassium permanganate solution in a certain proportion.
Second, carbon dioxide absorbent.
Carbon dioxide absorbent can adjust the carbon dioxide content, mainly including activated carbon, lime and magnesium chloride. In addition, coke molecular sieve can absorb ethylene and carbon dioxide.
Third, the growth of regulatory agencies.
Substances (phytohormones) that have physiological activities on plant growth and chemical T agents that can regulate or stimulate plant growth can regulate the physiological activities of fruits and vegetables. There are mainly auxins, such as 2,4-D, gibberellin (AG3), cytokinin, etc. And growth inhibitors (such as Bijiu, Qingxian, Chlormequat, etc.). ), wax and coating agent.
Fourth, oxygen inhalers.
Oxygen absorbent absorbs oxygen, reduces oxygen content and inhibits the growth of oxygen-consuming microorganisms. There are mainly ascorbic acid, bisulfite and some metals such as iron powder.
Five, antiseptic bactericide
Anticorrosive bactericides use chemical and natural antibacterial agents to prevent the propagation of molds and other polluting bacteria, including borax, sodium sulfate, sorbic acid and its salts, propionic acid, ortho-phenol (HOPP), clonidine (PCNA), bacteriostatic spirit, etc. The most commonly used is sodium ortho-phenolate (SOPP), which is mainly used to prevent pathogenic bacteria from invading fruits and kill microorganisms on the surfaces of fruits and vegetables.
Six, water regulator
The water regulator is moderately regulated, including steam inhibitor and dehydrating agent. It is usually adjusted by applying moisture evaporation inhibitor and anti-coagulation agent in plastic film packaging. For example, sodium polyacrylate can release the trapped water to adjust the humidity when the humidity in the bag drops.
