以食品级脱氢醋酸钠为保鲜剂,采用浸泡处理的方式,以感官评价、失质量率、呼吸速率及保护性酶活作为评价指标,评价4种浓度(0.01%、0.02%、0.03%和0.04%)脱氢醋酸钠对草菇保鲜效果的影响.结果表明,与对照相比,0.04%脱氢醋酸钠能降低呼吸强度,减少褐变,降低失质量率,改善草菇外观和品质；0.04%脱氢醋酸钠处理能有效抑制草菇的呼吸强度,使子实体硬实,在贮藏期间超氧化物歧化酶( SOD)活性和过氧化氢酶( CAT)活性均高于对照,并且丙二醛( MDA)含量显著降低.可见,0.04%脱氢醋酸钠处理可延长草菇货架期,而且成本低,操作简便.

Four concentrations (0. 01%,0. 02%,0. 03% and 0. 04%)of sodium dehydroacetate were used as food-grade preservative to soak Volvariella volvacea fruit body, and the fresh-keeping effect was eva1uated in appere-ance, weight 1oss, respiration rate and protective enzyme activities. The concentration of 0. 04% sodium dehydroace-tate reduced the respiration rate, browning and weight 1oss compared with the contro1, and improved the appearance qua1ity of Volvariella volvacea fruit body. It a1so effective1y inhibited the respiration intensity, hardened the fruit bodies, and increased the activities of superoxide dismutase and cata1ase and cowered 1eve1s of ma1ondia1dehyde during storage. Therefore, it was conc1uded that 0. 04% sodium dehydroacetate cou1d pro1ong the she1f 1ife of Volvariella volvacea fruit body at a 1ow cost.
