This document specifies three methods (two titrimetric and one potentiometric) for the determination of acidity in animal and vegetable fats and oils, hereinafter referred to as “fats”. The acidity is expressed preferably as acid value or, alternatively, as acidity calculated conventionally. This document is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty acids or technical fatty acids. It does not apply to waxes. Since the methods are completely non-specific, they do not apply to differentiating between mineral acids, free fatty acids and other organic acids. The acid value, therefore, includes any mineral acids that are present. Milk and milk products (or fat coming from milk and milk products) are excluded from the Scope of this document.
酸值的测定方法有很多个国标。GB/T 7304《石油产品和润滑剂酸值测定法(电位滴定法)》GB/T 264《石油产品酸值测定法》GB/T 5530 动植物油脂酸值和酸度测定GB/T 12008.5 塑料聚醚多元醇第5部分:酸值的测定...
GB/T一5530—2005规定了测定动植物油脂酸度的方法包括热乙醇测定法、冷溶剂测定法和电位滴定法,其中热乙醇测定法为参考标准法,冷溶剂法只适用于浅色油脂,电位滴定法是利用pH计判断滴定终点,然后根据滴定所需氢氧化钾的量计算油脂酸值。...
