摘要
为保持鲜切哈密瓜贮藏品质和效果,将具有防腐、抑菌作用的柠檬烯用于鲜切哈密瓜的保鲜。用无菌蒸馏水、0.05%、0.10%、0.20%浓度的柠檬烯溶液对鲜切哈密瓜进行处理,放在5℃下贮藏,研究不同浓度的柠檬烯处理对鲜切哈密瓜生理及品质的影响。结果表明,0.10%柠檬烯处理可以较好地保持鲜切哈密瓜的水分、色泽,保持维生素C含量,减少可溶性固形物的消耗,抑制呼吸强度,减缓硬度下降的速率,提高超氧化物歧化酶(superoxide dismutase,SOD)活性,贮藏后期较好保持过氧化氢酶(catalase,CAT)活性,抑制多酚氧化酶(polyphenol oxidase,PPO)和过氧化物酶(peroxidase,POD)活性,减缓鲜切哈密瓜的代谢,较好地保持鲜切哈密瓜的品质。该试验得出柠檬烯处理鲜切哈密瓜有利于保持鲜切哈密瓜的贮藏品质且0.1%的柠檬烯处理液对鲜切哈密瓜的保鲜效果最佳。
Limonene with natural antiseptic and bacteriostatic effects was used for the preservation of fresh-cut cantaloupes.Fresh-cut cantaloupes were treated with sterile distilled water,0.05%,0.10%,and 0.20%limonene solutions,and then stored at 5℃.The influences of different concentrations of limonene on the quality of fresh-cut cantaloupes were studied.The results showed that the treatment with 0.1%limonene well maintained the moisture,color,and vitamin C,reduced the consumption of soluble solids,inhibited the respiration rate,and slowed down the decline in the hardness of fresh-cut cantaloupes.Furthermore,the treatment increased the activity of superoxide dismutase(SOD),maintained catalase(CAT)activity in the later stage of storage,and inhibited the activities of polyphenol oxidase(PPO)and peroxidase(POD)to slow down the metabolism,thus maintaining the quality of fresh-cut cantaloupes.This experiment found that treating fresh-cut cantaloupes with limonene was beneficial for maintaining the storage quality of fresh-cut cantaloupes,and 0.1%limonene treatment solution had the best preservation effect on fresh-cut cantaloupes.
