对冷饮食品的卫生评价,目前多采用合格率等指标,但它不能反映超标程度上的差异。本文试图采用综合质量指数(WQI)即无量纲的相对数来定量和客观地评价冷饮食品的卫生状况。 1 建立质量指数计算式首先确定质量指数。通过计算式,将大量原始监测数据综合、换算成 Hygienic evaluation of cold drinks and foodstuffs, the current use of more indicators such as pass rate, but it does not reflect the degree of excessive differences. This article attempts to quantify and objectively evaluate the hygienic status of cold drinks and foods using the General Quality Index (WQI), a dimensionless relative number. 1 The establishment of quality index calculation formula First determine the quality index. Through the formula, a large number of original monitoring data synthesis, converted into
