摘　　要：为研究弱酸性电解水(WAEW)冰衣和气调包装(MAP)对水产品的杀菌保鲜效果,本文以凡纳滨对虾为研究对象,对其保藏过程中质地、颜色、挥发性风味、微生物活性、TVBN、TMA和TBARS的变化进行了研究。结果表明,经过40%CO_2+10%O_2+50N_2或30%O_2+20%O_2+50%N_2气调包装和弱酸性电解水冰衣处理的虾仁能够显著抑制需氧菌和金黄色葡萄球菌的生长(P<0.05);采用弱酸性电解水冰衣和气调包装后,冻虾中的TVBN、TMA、TBRS的值相对较低,L*和a*的值也表明,采用弱酸性电解水冰衣和气调包装联合处理能有效地保持虾仁的品质,对冷冻期间虾仁颜色的稳定性具有积极作用。但是WAEW冰衣对生虾仁的挥发性风味具有不良影响,对煮熟的样品没有显著影响。因此,弱酸性电解水冰衣结合气调包装作为一种新型的杀菌保藏技术,可以有效的保持水产品的品质和风味,延长产品的货架期。The effect of weak acid electrolysis water （WAEW） ice glazing and modified atmosphere pack- aging（MAP） on the sterilization and preservation of aquatic products, the Litopenaeus vannamei as the research object,was studied by monitoring the texture, color, volatile flavor and microbial activity o , TVBN, TMA and TBARS .he results showed that the shrimp treated with 40%CO2＋10%O2＋50N2 or 30%O2＋20%O2＋50%N2 and weakly acidic electrolyzed water were significantly （P〈0.05） inhibited aerobic and golden Staphylococcus growth; The values of TVBN, TMA and TBRS in frozen shrimp were relatively low,The values of L＊ and a＊ al- so indicate that the combination of weak acid electrolysis with ice and air conditioning can effectively maintain the quality of shrimp and have a positive effect on the stability of shrimp during freezing.However, WAEW ice coat has an adverse effect on the volatile flavor of shrimp and has no significant effect on cooked samples. Therefore, the weak acid electrolysis of water ice combined with modified atmosphere packaging as a new typeof sterilization technology, can effectively maintain the quality and flavor of aquatic products and extend the shelf life of the product.
