Title

EFFECT OF CULTIVAR, OSMOSIS, PACKAGING AND STORAGE TEMPERATURE ON QUANTITATIVE AND QUALITATIVE CHARACTERISTICS OF DRIED MELON

Pages

  403-414

Abstract

 Introduction: This research was carried out in order to investigate the effects of packaging type and storage temperature on qualitative and quantitative characteristics of dried melon.Materials and methods: “Thashkandi” and “Khatoni” melon varieties; osmotic solutions (0% (control) and 10% sucrose) and cabinet dryer (50°c with low air velocity) were employed for dried melon production. Dried fruits were packed with modified atmosphere (polyamid-polyethylene fim, 85 micron thickness, and two gas mixtures) and without modified atmosphere (polyethylene and polystyrene films).100 grams of dried melon were used for each package. For modifying atmosphere, 2 gas mixtures (70% CO2%, 30% N2 and 60% CO2%, 40% N2) were applied.Discussion & Results: Generally, the results showed that control samplein 10% osmotic solution keptin 25°Cand4°Chad 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°Cshowedthe highest L* (brightness) and b* (yellowness) values while the highest a* (redness) value was observed at 25°C.Khatooni cultivar produced dried melon with higher a* (redness). Dried melon pretreated by 10% osmotic solution and packed in atmosphere 2 showed the least a* (redness). Dried melon preserved at4 °C showed highest CO2% and at 25°C showed thehighestO2% in package. Tashkandi and Kkatooni had higher CO2% and O2% respectively. Furthermore dried melon pretreated by 10% osmotic solution and packed in atmosphere 2 and preserved in 4°C for 6 months had minimum O2% and maximum CO2% in package.Finally, the results showed that dried melon “tashkandi” pretreated by 10% osmotic solution and packed in atmosphere 2 and preserved in 4°C for 6 months maintained its qualitative and quantitative characteristics better than the other treatments.
