中文摘要：为探究不同条件下的微酸性电解水(SAEW)镀冰衣处理对凡纳滨对虾杀菌效果及贮藏品质变化的影响,以SAEW冰衣有效氯质量浓度(ACC)、浸泡时间、镀冰衣次数为单因素,设置单一杀菌试验,分析不同条件的SAEW镀冰衣处理对凡纳滨对虾贮藏期间菌落总数、总挥发性盐基氮(TVBN)值、pH值、丙二醛(MDA)含量、色差、质构、保水性和水分分布的影响,确定最佳工艺条件。结果表明,ACC为40mg/L,浸泡20s得到的SAEW冰衣液浸泡2次对虾,SAEW冰衣处理组样品的菌落总数、TVB-N、MDA含量与pH值低于自来水冰衣组,其质构、保水性和色差值也优于自来水冰衣组,低场核磁结果显示其有更短的弛豫时间及更高的不易流动水含量。SAEW镀冰衣处理对控制样品脂肪氧化与腐败变质有较好的效果,对样品的原有品质影响较小。

外文摘要：To explore the effect of slightly acidic electrolyzed water(SAEW)ice glazing treatment under different conditions on the sterilization effect and meat quality changes of Litopenaeus vannamei during storage.A singlefactor sterilization experiment was conducted,employing available chlorine concentration(ACC)of SAEW ice glazing,soaking time,and the number of ice glazing treatments as the single variance.The study analyzed the effect of SAEW ice glazing treatment under dfferent conditions on the total bacterial count,total volatile basic nitrogen(TVB-N),pH value,malondialdehyde(MDA)content,color difference,texture,water retention,and moisture dis-tribution of Litopenaeus vannamei during storage,to determine the optimal process conditions.The results showed that Litopenaeus vannamei were treated with the SAEW ice glazing solution with an ACC was 40 mg/L,soaked for 20 seconds,and glazed twice had lower total bacterial count,TVB-N,MDA content,and pH value compared to the samples treated with tap water ice glazing.Moreover,the texture,water retention,and color difference values of the SAEW ice glazing treatment group were better than those of the tap water ice glazing group.Low-field nuclear magnetic resonance results showed that the SAEW ice glazing treatment group had a shorter relaxation time and higher immobile water content.The SAEW ice glazing treatment has a positive effect on controlling fat oxidation and spoilage of the samples,with minimal negative impact on the original quality of the samples.
