利用气相色谱测定大豆粕中溶剂残留的方法探讨
|
摘要
本文对GB/T 5009.117-2003《食用豆粕卫生标准的分析方法》国家标准与GB 5009.262-2016《食品安全国家标准食品中溶剂残留量的测定》中粕类溶剂残留的检测方法进行了研究,实验证明使用GB 5009.262-2016国标方法中顶空条件检测豆粕残溶结果偏低,原因可能为用固体(豆粕)做为基底,加入的6号溶剂附着在豆粕表面或以气体的形态悬浮在顶空瓶中,与实际浸出豆粕样品有较大差异,从而导致豆粕残溶检测结果偏低。同时本文还探讨了基底粕制备方法。
In this paper, the GB/T 5009.117-2003 "Analytical Method for Sanitary Standards for Edible Soybean" was tested and the method for detecting solvent residues in GB 5009.262-2016 "Determination of Solvent Residues in Food Safety National Standards" was studied,The experiment proves that the use of headspace conditions in GB 5009.262-2016 national standard method to detect the residual residue of soybean meal is low, The reason may be that solid(bean meal) is used as the base, The added solvent No. 6 is attached to the surface of the soybean meal or suspended in a headspace bottle in the form of a gas, There is a big difference between the actual leaching of soybean meal samples, Resulting in low detection results of soybean meal residue. At the same time, this paper also discussed the preparation method of substrate.
