Animal and vegetable fats and oils — Determination of water content — Entrainment method 动植物脂肪和油——水含量的测定——夹带法
发布日期: 1980-08-01
该方法适用于含水量大于或等于0.5%(m/m)的产品。它包括在不与水混溶的有机液体的帮助下,通过共沸蒸馏夹带试验部分中的水,并测量收集的水的体积。图中显示了合适的蒸馏设备。
The method is applicable to products having water content greater than or equal to 0,5 % (m/m). It consists in entraining of the water present in a test portion, by azeotropic distillation with the aid of an organic liquid not miscible with water, and measuring of the volume of water collected. A figure shows a suitable distillation apparatus.
