Abstract

Longkong has a short shelf life (3 to 5 days) at ambient temperature due to its pericarp browning and biochemical quality loss. The present study investigated the quality changes of longkong fruit during storage under passive modified atmospheric packaging (MAP) at ambient temperature (25 oC and at 85 % relative humidity). Fruit stored without MAP served as a control. The accumulation of headspace gas (% CO 2 ) in the fruit package was observed less than 65 % during all over the storage. The increase of fruit weight loss was effectively controlled in passive MAP storage than the control. Passive MAP storage maintained the lowest browning index values as compared to the control during storage. Throughout the storage, pericarp phenylanine ammonia lyase, polyphenol oxidase and peroxidase had higher activities in the control fruits. The significant changes in fruit pH, titratable acidity (TA), total soluble solids (TSS) and TSS/TA content were observed in both the control and passive MAP during the storage. Fruits stored under passive MAP had more scavenging ability than reducing power during storage. However, due to lower surface mould growth, the passive MAP stored longkong had a quality and shelf life of up to 12 days at ambient temperature. doi: 10.14456/WJST.2015.17

包装对龙岗采后品质变化的影响

由于果皮褐变和生化品质损失，龙空在常温下的保质期很短(3 - 5天)。本文研究了龙井果在25℃、85%相对湿度条件下被动改性大气包装(MAP)贮藏过程中的品质变化。没有MAP的水果作为对照。在整个贮藏过程中，果实包装中顶空气体(% CO 2)的累积量小于65%。与对照相比，被动MAP贮藏有效地控制了果实失重的增加。与对照组相比，被动MAP存储在存储过程中保持了最低的褐变指数值。在贮藏过程中，对照果实中苯胺解氨酶、多酚氧化酶和过氧化物酶的活性均较高。对照和被动MAP贮藏期间果实pH、可滴定酸度(TA)、总可溶性固形物(TSS)和TSS/TA含量均发生了显著变化。在被动MAP条件下贮藏的果实在贮藏过程中具有较强的清除能力而非还原能力。然而，由于表面霉菌生长较低，储存在香港的被动MAP在室温下的质量和保质期可达12天。doi: 10.14456 / WJST.2015.17
