标准编号:ISO 660:2009
中文名称:动植物的脂肪和油 酸值和酸度测定
英文名称:Animal and vegetable fats and oils — Determination of acid value and acidity

标准范围
ISO 660:2009规定了测定动植物脂肪和油中酸度的三种方法(两种滴定法和一种电位法)。酸度最好表示为酸值,或者可选地表示为按常规计算的酸度。ISO 660:2009适用于精制和粗加工的植物或动物脂肪和油、皂液脂肪酸或工业脂肪酸。这些方法不适用于蜡。由于这些方法是完全非特异性的,因此不能用于区分矿物酸、游离脂肪酸和其他有机酸。因此,酸值还包括可能存在的任何矿物酸。
ISO 660:2009 specifies three methods (two titrimetric and one potentiometric) for the determination of the acidity in animal and vegetable fats and oils. The acidity is expressed preferably as acid value, or alternatively as acidity calculated conventionally.ISO 660:2009 is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty acids or technical fatty acids. The methods are not applicable to waxes.Since the methods are completely non-specific, they cannot be used to differentiate between mineral acids, free fatty acids, and other organic acids. The acid value, therefore, also includes any mineral acids that may be present.
