摘　　要：以新疆甜瓜为试材,分析在温度25℃、相对湿度55%~60%条件下,油菜籽粕酶解液对甜瓜采后贮藏品质及生理指标的影响。结果表明,与对照组相比,油菜籽粕酶解液能够有效降低甜瓜的呼吸强度、质量损失率和相对电导率,维持果实硬度、糖酸和V_C的含量,抑制丙二醛的增加,提高过氧化物酶活性,较好地保持了果实的品质和风味,说明油菜籽粕酶解液可以作为天然保鲜剂应用于甜瓜采后贮藏保鲜。To evaluate the postharvest quality and physiological index of Xinjiang melon,rapeseed meal hydrolyzate was used on it under25 ℃,relative humidity 55% ～60% surroundings.Results showed the hydrolyzate of rapeseed meal could decrease the respiratory intensity,weight loss rate and relative electrical conductivity of muskmelon, maintained the fruit hardness,sugar,acid and vitamin C content,inhibited the increasing of malonaldehyde content,improved the activity of peroxidase.Thus could maintain the quality and flavor of muskmelon fruit.Rapeseed meal hydrolysate can be used as a natural preservative for muskmelon postharvest storage.
