摘　　要：本研究选用不同透气性的商品膜(聚偏二氯乙烯(polyvinylidene chloride,PVDC)及3种聚乙烯基保鲜膜(BXD3C、BXD4C、CRM1C)),对采后双孢蘑菇进行包装处理,通过测定包装处理后双孢蘑菇的生理生化指标,探究双孢蘑菇在4℃贮藏期间的品质和呼吸代谢变化。结果表明,在4种膜中,CRM1C透气性最优,BXD3C和BXD4C次之,PVDC最差。贮藏至第15天,与BXD3C、BXD4C、PVDC包装相比,CRM1C包装可以有效抑制采后双孢蘑菇的呼吸速率,减少丙二醛积累和胞内电解质泄漏,维持VC含量,抑制褐变指数增加;同时还可以保持双孢蘑菇体内糖酵解限速酶(丙酮酸激酶、磷酸果糖激酶)、三羧酸循环及电子传递链限速酶(α-酮戊二酸脱氢酶、琥珀酸脱氢酶)的活性,维持细胞组织的能荷水平,提高ATP酶的活性,保证双孢蘑菇在贮藏后期的能量供应,从而延缓其采后褐变。本研究结果可为双孢蘑菇采后保鲜提供参考。In this study,commercial films with different permeabilities(polyvinylidene chloride(PVDC),BXD3C,BXD4C and CRM1C)were selected for packaging treatment of postharvest Agaricus bisporus to investigate the changes in the storage quality and respiratory metabolism of Agaricus bisporus at 4℃.The results showed that CRM1C had the greatest permeability among the four films,BXD3C and BXD4C were in the middle,and the permeability of PVDC was worst.On the 15th day of storage,compared with BXD3C,BXD4C,and PVDC packaging,CRM1C packaging could effectively inhibit the respiration rate of postharvest Agaricus bisporus,reduce malondialdehyde(MDA)accumulation and intracellular electrolyte leakage,maintain vitamin C content,and inhibit the increase of browning index.Meanwhile,CRM1C packaging could maintain the activities of rate-limiting enzymes in glycolysis(pyruvate kinase(PK)and phosphofructokinase(PFK)),the tricarboxylic acid cycle and the electron transport chain(α-ketoglutarate dehydrogenase(α-KGDH)and succinate dehydrogenase(SDH))as well as cellular energy charge in Agaricus bisporus,and increase the activity of adenosine triphosphate(ATP)synthase,ensuring energy supply in Agaricus bisporus in the late storage period and delaying postharvest browning.The results of this study can provide a reference for the post-harvest preservation of Agaricus bisporus.
