【摘要】 以中华鳖为研究对象,采用不同气调包装处理中华鳖,测定其在（4±1）℃贮藏过程中微生物、理化指标的变化情况,评价气调包装（M₁:30%CO₂/70%N₂;M₂:50%CO₂/50%N₂;M3:70%CO₂/30%N₂）对中华鳖品质的影响,并以空气包装和真空包装为对照组。结果表明:相比空气和真空包装而言,气调包装（M₁、M₂、M3）有效抑制了微生物的生长繁殖,延缓中华鳖的腐败变质;中华鳖气调包装最适气体配比为50%CO₂/50%N₂,其货架期可达18 d。更多还原

【Abstract】 In this study, the Trionyx sinensis was packaged in plastic film（A）, vacuumed packaging（VP）, placed in modified atmosphere packaging（MAP; M₁: 30% CO₂/70% N₂; M₂: 50% CO₂/50% N₂; M3: 70% CO₂/30% N₂）, and stored at 4 ℃. Microbiological, chemical analyses were conducted to determine the changes in quality. Compared with A and VP, MAP could inhibit the spoilage of the Trionyx sinensis, and then extend the shelf-life. The packaging with50% CO₂/50% N₂ is the optimum MAP, whose shelf-life of Trionyx sinensis could achieve 18 days. Total viable bacteria counts did not exceed the limit of consumption（6.0 lg cfu/g） for M₂ on 18 d. Total volatile basic nitrogen（TVB-N）and thiobarbituric acid reactive substances（TBARS） values of M₂ remained lower than the proposed acceptability limits of20 mg/100 g and 1.0 mg MDA/kg.更多还原
