THE EFFECTS OF PACKAGING AND METHYL JASMONATE APPLICATIONS ON THE POST-HARVEST QUALITY OF PLEUROTUS OSTREATUS (JAQU. EX FR.) P. KUMM.(OYSTER MUSHROOM)

Abstract

In this study, the effects of different modified atmosphere packaging (MAP) and Methyl Jasmonate (MeJA) on postharvest quality and storage life of oyster mushroom (Pleurotus ostreatus) species were investigated. P. ostreatus produced in the mushroom production facilities of Van Yuzuncu Yil University Mushroom Research Center were subjected to 1 day pre-cooling. The mushrooms with the same maturity were divided into 3 separate groups, while the first group samples were immersed only in distilled water as the control group, the second group samples were immersed in 0.5 mM MeJA and the third group samples in a 1.0 mM dose of MeJA solution for 2 minutes. The mushrooms were taken in a foam plate and covered with stretch film and LifePack MAP and stored in a cold store with 4ºC temperature and 90-95% relative humidity. At the end of the study, P. ostreatus was successfully stored at 4 ° C for 14 days. While the stretch film was effective on oxygen, one of the gas compositions in the package, and respiration rate; LifePack MAP was found to be effective in weight loss, TA, L *, croma, hue, ethylene and carbon dioxide, one of the gas components. It was observed that MeJA had significant effects on post-harvest quality and storage life in P. ostreatus
