标准摘要
[中文适用范围]: 干物质含量的测定方法包括将散布在吸收表面上的液体或半液体产品或与惰性粉末混合的糊状产品混合后在70℃减压下加热至恒质量。 水含量的测定方法包括用与水不混溶的挥发性溶剂夹带蒸气形式的水,在回流阱中冷凝和分离,在刻度管中回收和测量水的体积。 [外文原描述]: The method of determination of dry matter content consists in heating to constant mass, after mixing, of liquid or semi-liquid products spread over an absobent surface, or of pasty products mixed with an inert powder, at 70 °C under reduced pressure. The method of determin of water content consists in entraining of the water in the form of vapour by a volatile solvent immiscible with water, condensing and separating in a reflux trap, recovering and measuring of the volume of water in a graduated tube.
英文名称Fruit and vegetable products — Determination of dry matter content by drying under reduced pressure and of water content by azeotropic distillation
