Title

EFFECT OF 1-METHYLCYCLOPROPENE AND POTASSIUM PERMANGANATE-COATED ZEOLITE NANOPARTICLES ON EXTENDING THE SHELF LIFE AND QUALITY OF GOLDEN AND RED DELICIOUS APPLES

Abstract

 Background and Objective: Apple production is high in Iran; using effective packaging and storing technologies can prevent loss of this valuable fruit and provide a source of non-oil exports. Ethylene plays an effective role in the loss of apple quality. This study examined the effect of ethylene reduction on improving the quality of Golden and Red Delicious APPLES during cold storage.Materials and Methods: Golden and Red Delicious APPLES were tested in an experimental design using a split-plot over time in a completely randomized design and three replications for 1-METHYLCYCLOPROPENE (1-MCP, 0 and 1 ppm) and POTASSIUM PERMANGANATE-coated zeolite NANOPARTICLES (0 and 10 g). The fruit was stored at ± 0.5oC and 90% RH for up to 5 mo. Fruit quality parameters (weight loss, firmness, pH, titratable acidity, total soluble solid concentration) were evaluated before storage and on a monthly basis during the storage period. Vitamin C concentration was also measured at the beginning and end of storage.Results: A comparison of means showed the lowest pH (4.39), lowest reduction in TA (0.31%), lowest TSS (14.28%), highest firmness value (17.54 N/m2), lowest weight reduction (3.10%) and highest vitamin C concentration (6.27 mg/100g-1) were obtained for APPLES treated with 1-MCP combined with ETHYLENE ABSORBER sachets. The lowest pH (4.39), highest reduction in TA (0.25%), highest TSS (15.1%), lowest firmness value (14.30 N/m2), highest weight reduction (3.51%) and lowest vitamin C concentration (5.26 mg/100g-1) was found for the control APPLES.Conclusion: The application of 1-MCP combined with ETHYLENE ABSORBER sachets had the best effect on the quality characteristics of both species. Red Delicious APPLES were firmer and fresher in appearance, indicating that this variety has better storability.
