摘　　要：针对常温储藏工艺包装的鱼丸,研究其货架期模型,以便于电商在销售鱼丸时能够较准确地掌握其保质期。以鱼丸的TVB-N值为依据,建立基于反应动力学的一级反应动力学货架期模型和直接借助统计学计算工具(1st Opt和MATLAB)建立二元非线性货架期模型,并利用鱼丸的菌落总数检验两种货架期模型的准确性。研究结果表明,一级反应动力学货架期模型需要通过大量数据与公式的转换后计算得到,过程较复杂,但能够较好解释温度与货架期之间的关系;二元非线性货架期模型借助统计学工具,建模简单、计算容易,但是尚不能解释温度与货架期的关系,且对货架期的计算需要使用MATLAB专业数学软件,不便于普通电商用户使用。两种货架期模型均具有一定精度,但一级反应动力学货架期模型更准确,故推荐普通电商用户使用一级反应动力学货架期模型。The shelf life model of fish balls packed at room temperature was studied for the convenience of online shops selling fish balls to control the shelf life more accurately. According to the TVB-N value of fish balls, a shelf life model based on reaction kinetics and a two element nonlinear shelf life model with the help of statistical tools （1stOpt and MATLAB） were established. Then, the accuracy of the two shelf-life models was tested by the total numbers of colony. The results showed the primary reaction kinetics shelf life model had to be calculated by the conversion of a large number of data and formulas, but it could better explain the relationship between the temperature and the shelf life in spite of the complex process. The two element nonlinear shelf life model was simple and easy to calculate with the help of statistical tools, but it could not explain the relationship between the temperature and the shelf life. Moreover, the calculation of shelf life had to resort to professional software of MATLAB, which made it hard in application for common online shops. Both of the two models demonstrated certain degree of accuracy, the primary reaction kinetics shelf life model was recommended for common users since it was more precise.
