Study on respiratory rate and MAP storage technique of Jiefangzhong loquat fruits
-
摘要: 以枇杷品种——解放钟为试验材料,研究不同贮藏温度(4～20℃)对其果实呼吸强度的影响,以及8～10℃温度条件下不同包装膜厚度、装果量等因素对 MAP 保鲜效果的影响。结果表明,低温能显著抑制解放钟的呼吸作用．但贮藏温度低于6℃时有呼吸反弹现象;解放钟适宜的贮藏温度为8～10℃。采用 MAP 保鲜技术能延缓果实品质的下降,显著延长果实的贮藏期(达30d 以上);PE 膜厚度决定了批杷包装保鲜的单位面积适宜装果量,随着包装膜厚度的增加,适宜装果量减少;0.03mm 或0.02mm 厚度的低压 PE 膜,其适宜装果量分别为3.6kg·m-2和6.4kg·m2-。Abstract: MAP storage technique for Jiefangzhong loquat,such as storing temperature,thickness of packaged film and packaged fruit weight were studied,the result indicated that low temperature significantly inhibited fruit respiration,but the respiratory rate increased when storing temperature below 6 C;the best storing temperature of Jiefangzhong loquat was 8—10C;MAP storage could greatly prolong the storing time and delay the decrease of fruit quality,the storing time could be over 30 days.Under the same superficial dimension,the thickness of film decided the proper packaged fruit weight,their proper packaged fruit weight were 3.6 kg·m-2 and 6.4 kg·m-2with 0.03 mm and 0.02 mm polyethylene film.
