摘要
以"北农佳秀"黄瓜为试材,采用0.1mmol·L^(-1)硝普钠(sodium nitroprusside,SNP)溶液浸泡黄瓜10min,研究了外源NO处理对黄瓜采后贮藏期间生理特性及品质的影响。结果表明:黄瓜在贮藏期间,丙二醛含量上升,硬度、可溶性固形物、维生素C、叶绿素等含量降低,而0.1mmol·L^(-1)硝普钠处理可有效保持黄瓜的品质,抑制丙二醛含量的上升,抑制硬度、可溶性固形物(TSS)、维生素C、叶绿素含量的下降,提高过氧化氢酶(CAT)、过氧化物酶(POD)活性,较好的维持黄瓜采后品质和营养价值。
The＇Beinongjiaxiu＇cucumber were used as raw materials to sodium nitroprusside（SNP）treatment.After pre-experiment,cucumber was treated with 0.1 mmol· L^-1 SNP solution for10 minutes to study the effects of NO treatment on postharvest quality and nutritional value.The results showed that during storage,the malondialdehyde content in cucumber increased,the firmness,soluble solids（TSS）,ascorbic acid（VC）and chlorophyll contents decreased.0.1 mmol·L^-1 SNP treatment can effectively maintain the quality of cucumber,delay the increase of malondialdehyde content,inhibite the decrease of firmness,TSS,VC and chlorophyll,increase the activities of catalase（CAT）and peroxidase（POD）,and better maintain the quality and the nutritional value of postharvest cucumber.
