摘　　要：以往对生鲜牛乳质量评定有重营养、轻安全的倾向。"上海市生鲜牛乳按质计价办法"中对生鲜牛乳的计价方法是以其营养指标为主,而忽视了对各指标的综合考虑。将模糊乘加综合评价法运用到生鲜牛乳的质量评定中,以脂肪、蛋白质、体细胞、菌落总数、冰点5个指标作为评定因子。将评定结果与根据"上海市生鲜牛乳按质计价办法"计算得到的价格进行对比,结果发现调整权值可以改善现行办法中以营养指标含量主导价格的状况。Previous quality assessment of raw milk has only shown a tendency to take care of more the nutrition than the safety.‘The valuation method based on quality for raw milk in shanghai’ is mainly based on the nutrition indicators of raw milk,but not the integrated consideration of various indicators.In this paper,the fuzzy comprehensive evaluation method,which taking fat,protein,somatic cells,total plate count and the freezing point as assessable factor was used into assessing the quality of raw milk.Comparing the assessing results got by fuzzy evaluation model to the price calculated through ‘The valuation method based on quality for raw milk in shanghai’,that the problem of the nutritional content guide the price in previous quality assessment can be improved by adjusting the weight of fuzzy model was found.Thus some useful suggestions about the valuation method based on quality for raw milk could be put forward.
