BACKGROUND: A study was conducted to determine the effects of modified‐atmosphere packaging (MAP) treatments on fruit quality attributes and bioactive compounds of cornelian cherry fruits (Cornus mas L.) harvested at two different maturity stages – maturity (M): M‐1, skin red color <10%; M‐2, skin red color >90% – throughout the shelf life. Fruits were stored at 0 ± 0.5 °C and 90 ± 5% relative humidity (RH) for 30 days, and then kept at 22 ± 0.5 °C and 80 ± 5% RH over 3 days for shelf life. RESULTS: In the measurements performed at harvest, MS‐2 fruits had significantly greater respiration rate, soluble solids content, acidity, anthocyanin, flavonoids, and phenolics and significantly lower ethylene productions, firmness, L*, chroma, and hue angle values than MS‐1 fruits. In the last measurement period, MAP‐treated fruits had significantly greater firmness, total flavonoids, and total phenolics and significantly lower respiration rates, ethylene productions, and decay rates than the untreated fruits. While color parameters of MS‐2 fruits were significantly lower than the color values of MS‐1 fruits, they had greater vitamin C and anthocyanin contents. CONCLUSION: It was concluded that the cornelian cherry fruits harvested at MS‐2 stage of maturity and preserved in MAP better maintained quality attributes throughout their shelf life. © 2018 Society of Chemical Industry
