目的：比较不同通透性保鲜膜对平菇品质及内源甲醛的影响。方法以新鲜的平菇为原料,分别以市售的低通透性保鲜膜(旭包鲜PVDC保鲜膜)、中等通透性保鲜膜(潘多拉PE保鲜膜)和高通透性保鲜膜(好丽家PE保鲜膜)为包装材料,在模拟超市冷鲜货架温湿度条件(温度14±1℃,贮藏环境相对湿度85%)下,研究3种不同通透性保鲜膜对平菇的保鲜效果。结果3种不同通透性的保鲜膜阻水性能差异不显著(P>0.05)；与低通透性保鲜膜和高通透性保鲜膜相比,中等通透性保鲜膜能显著抑制平菇子实体抗坏血酸、多糖、可溶性蛋白质含量的下降,保持平菇最佳的感官品质(P<0.05),高通透性保鲜膜和中等通透性保鲜膜均能显著抑制平菇中甲醛含量的上升(P<0.05)。结论3种不同通透性保鲜膜以中等通透性保鲜膜(潘多拉PE保鲜膜)对平菇的综合保鲜效果最佳。

ABSTRACT:Objective To compare the effect of three different kinds of cling film onPleurotus ostreatus fresh-keeping and the content of formaldehyde.MethodsLow permeability (PVDC) film, medium permea-bility(PE) film, and high permeability(PE) film were studied onPleurotus ostreatus fresh-keeping at 14±1℃and relative humidity around 85%, which was simulated cold fresh supermarket shelf temperature and humidity. Results It showed that there was no significant difference of weight loss of 3 kinds of different permeability films (P>0.05). Compared to low permeability film and high permeability film, medium permeability cling film could significantly inhibit the decline of ascorbic acid, polysaccharide, soluble protein content, keeping the best sensory quality mushroom (P<0.05). Medium permeability and high permeability cling film could significantly inhibit the rise of formaldehyde content in the mushroom (P<0.05).ConclusionThe fresh-keeping effect was the best whenPleurotus ostreatus packaged by medium permeability cling film.
