Development of an Active Film With Natural Zeolite as Ethylene Scavenger

Abstract

Ethylene (C 2 H 4 ) acts as a plant hormone, growth regulator that has a number of effects on the growth. Ethylene accelerates respiration, leading to maturity and also softening and ripening of many kinds of fruits. Although ethylene has some positive effects, it is often hazardous to the quality and shelf-life of fruits and vegetables. The removal of ethylene and/or inhibition of the effect of ethylene in stored environments is fundamental to maintaining postharvest quality of climacteric produce. In this study, the efficiency of a Chilean natural zeolite (NZ-Ch) against a commercial Na + montmorillonite (Cloisite Na + ) was studied. The aluminosilicate characterization (XDR, FTIR, EGME, CEC, chemical composition) indicates that natural Chilean zeolite belongs to mordenite group. Elemental chemical analysis indicated that compensating ions, were sodium for MTNa + and calcium, sodium and potassium for NZ-Ch, and in both aluminosilicates copper was present in their composition. Ethylene adsorption kinetics were fitted to a pseudo-second order model. The rate constant of the ethylene adsorption was nearly double for NZ-Ch compared with MtNa

Efficacy of chitosan‐coated paper incorporated with vanillin and ethylene adsorbents on the control of anthracnose and the quality of Nam Dok Mai mango fruit

“…Afterwards, all glass containers were stored at 25°C for 35 days. The amount of ethylene was determined every 7 days according to the method of Coloma et al with modification. Each container was vigorously shaken to increase the dispersion of gas.…”

Application of palladium‐modified zeolite for prolonging post‐harvest shelf life of banana

“…This is because present technologies tend to have high transportation and operation costs, energy demands, and potentially produce toxic chemicals . Ethylene removal using zeolite as an adsorbent has received considerable attention in both industry and agriculture application . Trinh et al .…”

“…compared the efficiency of three different zeolites for adsorbing ethylene from an air steam and showed that silver (1.0%)/13X zeolite had high ethylene adsorption affinity. Even though zeolite has a strong ethylene adsorption affinity, its adsorption capacity is limited by its porosity and chemical nature . Improvement of ethylene removal can be achieved by doping catalysts or nanoparticles (NPs), such as palladium (Pd), titanium, copper, rhodium, and cobalt, onto zeolite or other carrier .…”
