Ethylene adsorbent and preparation method thereof

Abstract

The invention relates to a preservative used for adsorbing ethylene generated during the preservation and the transportation of fruits and vegetables. The endemic bentonite in the Xinjiang province is adopted as an acidic material, the release rate of the acidic material is effectively reduced to achieve the slow release of the acidic material, and the effective combination of the acidic materialand potassium permanganate increases the adsorption efficiency of potassium permanganate, so as to achieve the purpose of rapidly and effectively removing ethylene and increasing the preservation time of fruits and vegetables. In the invention, potassium permanganate and acidic bentonite are adopted as the main materials of the ethylene adsorbent and mixed uniformly and proportionally with inorganic salts and then packaged with non-woven fabric or an air-permeable film to make the ethylene adsorbent with high adsorptivity. The ingredients of the ethylene adsorbent are as follows: potassium permanganate 15% to 35%, acidic bentonite 60% to 80%, and inorganic salts 0% to 5%. The ethylene adsorbent has the advantages of high adsorptivity, good fresh-keeping effect, low price and long adsorption time, and is convenient for the application in the transportation and the preservation of fruits and vegetables.

Description

technical field [0001] The invention relates to an ethylene adsorbent used for fruit and vegetable transportation and refrigerated storage. Background technique [0002] Ethylene (CH 2 =CH 2 ) is a phytohormone, which is synthesized in large quantities before ripening, and has the functions of promoting the ripening of fruits and vegetables and regulating the ripening process of fruits and vegetables. Fruits and vegetables produce a large amount of ethylene during the storage process. Ethylene has the characteristics of self-catalysis. When the endogenous ethylene reaches the minimum effective concentration, it can induce the respiratory peak. Trace amounts of ethylene have a significant impact on the respiratory intensity and decay and aging process of stored fruits, such as Promote aging, promote ripening and softening, aggravate the loss of fruit and vegetable quality, reduce the resistance of fruits and vegetables to pathogenic bacteria, and cause physiological disorde...
