摘　　要：为探究保鲜冰箱间室氧分压对果蔬的保鲜效果,选择草莓、蓝莓、猕猴桃、菠菜、生菜、黄瓜六种果蔬,在A1保鲜冰箱(氧分压21%,湿度90%)、A2保鲜冰箱(氧分压18%,湿度88%)、A3保鲜冰箱(氧分压15%,湿度86%)冷藏20 d,测定贮藏期间果蔬的失重率、硬度、可溶性固形物、维生素C及多酚含量,评价三种保鲜冰箱的保鲜效果。结果表明:低氧型(氧分压15%、18%)保鲜冰箱对六种果蔬的保鲜效果优于高氧型(氧分压21%)保鲜冰箱,保鲜冰箱间室中较低的氧分压对果蔬的硬度、可溶性固形物、维生素C、多酚有较好的保留效果,能显著缓解果蔬中营养物质的损失。但是低氧型保鲜冰箱的相对湿度较低,导致比表面积大的果蔬水分流失严重,这类果蔬贮藏时应以控制湿度为主。To study the preservation effect of oxygen tensions in refrigerators on fruit and vegetable preservation,six kinds of fruits and vegetables(strawberry,blueberry,kiwi berry,spinach,lettuce,cucumber) were stored for twenty days in A1 refrigerator(21% O2,RH 90%),A2 refrigerator(18% O2,RH 88%) and A3 refrigerator(15% O2,RH 86%).The weight loss rate,hardness,soluble solids,vitamin C and polyphenol contents were determined to evaluate the preservation effect of refrigerators.The results showed that the preservation effect of low oxygen(15%,18% O2) refrigerator was better than that of high oxygen(21% O2) refrigerator on these kinds of fruits and vegetables.Lower oxygen tension in the fresh-keeping refrigerator room had better preservation effect on hardness,soluble solids,vitamin C and polyphenol contents of fruits and vegetables,and also significantly slowed down the loss of nutrients in fruits and vegetables.However,the relative humidity of low oxygen refrigerator was low,which resulted in serious water loss in fruits and vegetables with large specific surface area;therefore,humidity would be controlled in the storage of these kinds fruits and vegetables.
