Özet
This study tested a novel combination of hydrocolloid gum arabic (GA) and carboxymethyl cellulose (CMC) to extend postharvest life of tomatoes. For this purpose, tomato fruits were coated with GA 10%, CMC 0.5% and GA 10% + CMC 0.5%, and stored for 20 days at 20 C and 90 +/-& nbsp;2% RH. Application of biocomposite hydrocolloid coating reduced physiological weight loss, respiration rate, ethylene production, decay percentage and stress markers viz. malondialdehyde and hydrogen peroxide. Biocomposite hydrocolloid coating inhibited change in bioactive compounds (phenolics, ascorbic acid, and lycopene), color, organic acids, soluble sugars and up regulated enzymatic ROS scavenging mechanism in tomato fruit more than GA or CMC coating. Moreover, biocomposite coatings delayed senescence by reducing activity of cell wall degrading enzymes and maintaining cell wall fractions. Conclusively, the biocomposite coating based on GA and CMC was superior to their individual coating in prolonging ripening phase, delaying senescence and increasing the acceptability of tomato fruits for longer duration.
