Abstract

This research was carried out in order to investigate on the effects of packaging type and storage temperature on qualitative and quantitative characteristics of dried melon. “Thashkandi” and ‘ Khatoni” melon varieties؛ osmotic solutions of 0% and 10% sucrose and cabinet dryer were applied for dried melon production. Dried fruits were packed with modified atmosphere (PE-PA film, 85 micron thickness, two gas mixtures: (70% CO2%, 30% N2(1) and 60% CO2%, 40% N2(2)) and without modified atmosphere (polyethylene and polystyrene films). After 6 months results showed that control dried in 10% osmotic solution preserved in 25°c and 4°c treatment had the most and the least firmness respectively. Melon pretreated by 10% osmotic solution, packed in atmosphere 1 had the least water activity. Dried melon preserved in 4°c had higher L*(brightness) and b*(yellowness) indices. Khatooni cultivar produced dried melon with higher a*(redness). Dried melon pretreated by 10% osmotic solution and packed in atmosphere 2 had less a*(redness). Furthermore dried melon pretreated by 10% osmotic solution and packed in atmosphere 2 and preserved in 4°c had minimum O2% and maximum CO2% in package.
