“红优二号”品种西瓜冰温贮藏和冰温简易气调贮藏的研究

STUDY ON THE ICE TEMPERATURE STORAGE OF “RED GREAT NO.2”WATERMELON

利用冰温贮藏技术可以明显抑制西瓜的呼吸作用,减少各种营养成分的损失。但西瓜属冷敏性植物,低温条件下易发生冷害。在此基础上,结合MAP贮藏(modifiedatmospherepackage),改善了包装内的气体组成,提高了果实周围相对湿度,从而更有效地抑制了西瓜在贮藏过程中的糖、酸、VC等营养成分的损耗,并减少了冷害和褐变的发生,可最大限度的延长西瓜的贮藏时间,但从感官角度分析,风味和色泽不及直接进行冰温贮藏的西瓜。

The storage technology of utilizing ＂ice temperature＂can greatly retain respiration of watermelon and reduce loss of various nutritions composition.But watermelon belongs to cold sensitivity plant, low temperature condition could happen chilling injury.On the basis of this condition, ice temperature combines with MAP storage（modified atmosphere package） can improve the composition of gas in the package,increase the relative humidity of fruits around.That restrains the loss of the sugar,acid, vitamine C and other nutrition components in the storage of watermelon,and reduces the development of chilling injury and browning,then prolongs the time of the watermelon storage at the greatest degree.But from sensory organ analyzing,flavor and colour of watermelon in the ice temperature MAP storage is inferior to the watermelon of ice temperature storage directly.
