摘　　要：为研究在室温下用臭氧冰保鲜大黄鱼期间的品质变化,以菌落总数、感官评分、K值、挥发性盐基氮(total volatile base nitrogen,TVB-N)值、蒸煮损失率、硬度、咀嚼性为评价指标,对比用普通冰、臭氧冰和臭氧水淋洗后臭氧冰保鲜的大黄鱼在贮藏期间的品质变化。结果表明,臭氧冰保鲜组大黄鱼的感官评分明显优于普通冰保鲜组;第15天时,臭氧冰保鲜组比普通冰保鲜组的K值、TVB-N值和菌落总数分别低10%、8.0 mg/100 g、2.5 lg(CFU/g);从蒸煮损失率、硬度和咀嚼性的变化来看,臭氧冰保鲜的大黄鱼口感更佳;且在本批臭氧冰保鲜的大黄鱼中并未检测到溴酸盐,证明臭氧冰处理无溴酸盐毒害风险;臭氧冰保鲜与普通冰保鲜相比可延长3 d~5 d货架期。The quality changes in large yellow croaker(Larimichthys crocea)during preservation with ozone ice at room temperature were studied.Total viable count,sensory evaluation,K value,total volatile basic nitrogen(TVB-N)value,cooking loss rate,hardness,and chewiness were detected as evaluation indexes.The quality changes in large yellow croaker preserved by normal ice,ozone ice,and ozone ice after leaching with ozone water were compared.The results showed that the sensory scores of the ozone ice preservation group was much better than those of the normal ice preservation group.The K value,TVB-N value,and total viable count in the ozone ice preservation group were 10%,8.0 mg/100 g,and 2.5 lg(CFU/g)lower than those in the normal ice preservation group on the 15th day.The changes in cooking loss rate,hardness,and chewiness showed that large yellow croaker preserved by ozone ice had a better taste.No bromate was detected in these large yellow croakers preserved by ozone ice,proving that ozone ice treatment had no risk of bromate toxicity.Ozone ice preservation can extend the shelf life of large yellow croaker by 3 d-5 d compared with normal ice preservation.
