糕点中脂肪含量测定的不确定度评定

Uncertainty evaluation of fat content in pastry detection

根据JJF 1059———1999《测定不确定度的评定与表示》和GB/T 5009.6———2003《食品中脂肪的测定》原理,对糕点中脂肪含量的不确定度进行评定,建立不确定度的数字模型,系统分析并计算出食品脂肪含量测定全过程中的各分量值结果标准不确定度及扩展不确定度,建立一种简便、适用的脂肪含量测量不确定度的测定方法。

According to evaluation and expressing of uncertainty in measurement（JJF1059——1999） and the principle of fat content detection in food（GB/T 5009.6——2003）,a mathematical model was established.The mathematical model systematically analyzes and calculates the standard uncertainty and expanded uncertainty of the component value,respectively,in the process of fat content measuring,also create a convenient and applicable way to measure the uncertainty of fat content.
