臭氧熏蒸浓度对双孢蘑菇质构及营养品质的影响

Effects of different concentrations of ozone fumigation on the storage quality of Agaricus bisporus

目的:延长双胞菇采后贮藏保鲜期。方法:以A15双孢蘑菇为试材,采用不同质量浓度臭氧(14.89,29.77,44.65 mg/m^(3))熏蒸处理,分析双孢菇在(1±1)℃冷库贮藏期间感官、质构和营养品质的变化。结果:贮藏第8天,29.77 mg/m^(3)臭氧熏蒸处理延缓了双孢蘑菇硬度的降低,保持了较好的弹性、凝聚性和回复性,抑制了可溶性固形物、可溶性蛋白和维生素C的下降。结论:29.77 mg/m^(3)臭氧熏蒸处理的双孢菇贮藏期可延长至8 d。

Objective:This study aimed to investigate the effects of different concentrations of ozone fumigation on the texture and nutritional quality of post-harvest Agaricus bisporus during cool storage.Methods:‘A15’A.bisporus was treated with ozone gas with concentrations of 14.89,29.77 and 44.65 mg/m^(3)respectively,and the changes in related indicators of each group during(1±1)℃storage were analyzed,such as sensory,texture and nutrition.Results:When stored for 8 days,29.44 mg/m^(3)ozone fumigation treatments effectively maintained good springiness,cohesiveness and resilience,and delayed the decrease of the sensory quality,hardness,soluble solids,vitamin C and soluble protein content.Conclusion:The 29.77 mg/m^(3)ozone fumigation treatment of A.bisporus can most effectively to maintain it storage with an extension to 8 days.
