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.
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.
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.
本研究旨在通过对不同成熟度（M）的欧洲红樱桃果实（Cornus mas L.）进行改良气氛包装（MAP）处理，来确定其对果实品质属性和生物活性化合物的影响。两个成熟度阶段分别为：M-1，果皮红色<10%；M-2，果皮红色>90%。在整个货架期内，果实贮藏于 0±0.5°C 和 90±5%相对湿度（RH）下 30 天，然后在 22±0.5°C 和 80±5%RH 下贮藏 3 天。
在收获时进行的测量中，MS-2 果实的呼吸速率、可溶性固形物含量、酸度、花青素、类黄酮和酚类物质显著较高，而乙烯产量、硬度、L 值、彩度和色调值显著较低。在最后一次测量期间，与未处理的果实相比，MAP 处理的果实具有更高的硬度、总类黄酮和总酚类物质含量，更低的呼吸速率、乙烯产量和腐烂率。虽然 MS-2 果实的颜色参数显著低于 MS-1 果实，但它们的维生素 C 和花青素含量更高。
综上所述，在 MS-2 成熟度阶段收获的欧洲红樱桃果实，保存在 MAP 中可以更好地保持整个货架期的品质属性。© 2018 英国化学学会。
