中文摘要：培养Bacillus sp.CAMT22370菌株并提取葡萄糖氧化酶制成质量分数0.1%的粗酶液,分别以亚硫酸钠、植酸和VC为对照,探讨所得葡萄糖氧化酶对南美白对虾冷藏过程中感官、质构、挥发性盐基氮含量、菌落总数等品质指标的影响。结果表明,经葡萄糖氧化酶浸渍处理后于4℃冷藏120 h,感官评分在10分以上,不仅能有效防止对虾褐变,而且对其色泽、气味、硬度、弹性、咀嚼性和黏附性等品质指标都有良好的保持作用,显著优于空白对照组(P<0.05),挥发性盐基氮含量和菌落总数分别为20.40 mg/100 g和4.41(lg(CFU/g)),表明Bacillus sp.CAMT22370源葡萄糖氧化酶对南美白对虾冷藏保鲜有一定的作用。

外文摘要：The effect of treatment with a novel glucose oxidase at a concentration of 0.1%(m/m) produced by the marine bacterium Bacillus sp.CAMT22370 in liquid-state fermentation on the sensory quality,texture,total volatile basic nitrogen(TVB-N) and total viable count(TVC) of Pacific white shrimps was evaluated as compared with sodium sulfite,phytic acid and VC.The results revealed that Pacific white shrimps exhibited more desirable appearance,especially in terms of low melanosis,when immersed into glucose oxidase solution for 5 minutes,as compared with the control group.In addition,the sensory score of the treated sample was more than 10 points after 120 h of storage at 4 ℃.Glucose oxidase treatment not only effectively prevented the browning of shrimps but also significantly preserved the color,odor,hardness,elasticity,chewiness and adhesiveness(P < 0.05).Furthermore,TVB-N and TVC values were 20.40 mg/100 g and 4.41(lg(CFU/g)) respectively,after this period of storage.These findings indicated the glucose oxidase from Bacillus sp.CAMT22370 had the potential to be used for the preservation of Pacific white shrimps.
