中文摘要:为了研究南美白对虾虾仁中腐败菌引起的腐败品质变化动力学关系,以虾仁为原料接种优势腐败菌SL-1(Pseudoalteromonas sp.FJ404757.1),在不同温度条件下(273,277,281K)研究南美白对虾虾仁中SL-1菌和茵落数量、挥发性盐基总氮(TVB-N)的变化规律。结果表明,贮藏过程中TVBN值变化的一级动力学方程为K-6.78×10^18exp(-9.145×10^5/RT),菌落数量变化的一级动力学方程为K=2.21×10^16exp(-9.145×10^5/RT),TVBI—N的线性拟合系数(0.9559~0.9706)要优于菌落数量的线性拟合系数(0.9780~0.9906)。经验证,TVB-N方程在273~281K内,其预测值相比实际值的相对误差在5%以内,所建模型能较好地反映其贮藏品质变化过程。
外文摘要:To study the spoilage relationship between the spoilage and Spoilage microorganisms of Pen aeus Vanmamei , the dominant spoilage bacteria SL-1(Pseudoalteromonas sp. FJ404757. 1)was used as the experimental subject. Under the different temperature conditions (273, 277and 281 K), the impact on the quality of the TPC and TVB-N was described. In the process of storage, the first order kinetic equation between TVB-N was: (-9.145×10^5/RT), the first order kinetic equation of TPC was: K=2.21×10^16exp(-9.145×10^5/RT) ,The Linear regression coefficient (0.955 9-0. 970 6) of TVB-N showed better than linear fitting coefficient of TPC (0. 978 0-0. 990 6). To predict the quality kinetics model, between 273 and 281 K, relative error between predicted and observed shelf life were less than 5%, it is concluded that the model can better reflect the change process of storage quality.
