浩瀚色譜（山東）應用技術開發(fā)有限公司建立了食品接觸材料中1,4-丁二醇遷移量的測定——氣相色譜質譜法.以4%乙酸,10%乙醇,50%乙醇,95%乙醇,異辛烷五種模擬物對PBT筷子進行遷移試驗.模擬液在各自范圍內(nèi)線性相關系數(shù)均大于0.995,線性關系良好.取同一批供試品溶液按色譜條件連續(xù)進樣,RSD范圍在0.84%～1.72%之間,精密度良好,樣品加標回收率在90.5%～103.2%之間,回收率較好.經(jīng)方法學考察,該方法可用于食品接觸材料中1,4-丁二醇遷移量的測定.



Determination of 1,4-butanediol migration of food contact materials and products

Determination details of 1,4-butanediol migration of food contact materials and products:



Name: capillary column

Stationary solution: polyethylene glycol

Specification: 30m * 0.32mm * 0.25um

Model: PEG-20M

Application: National Food Safety Standard Determination of 1,4-butanediol migration of food contact materials and products



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography-mass spectrometry method to determine the migration amount of 1,4-butanediol in food contact materials. PBT chopsticks were migration tested with five simulants: 4% acetic acid, 10% ethanol, 50% ethanol, 95% ethanol, and isooctane. The linear correlation coefficients of the simulants in their respective ranges were greater than 0.995, showing a good linear relationship. The same batch of test sample solutions were continuously injected according to chromatographic conditions, The RSD range is 0.84% ～ 1.72%, and the precision is good. The recovery rate of sample spiking is 90.5% ～ 103.2%, and the recovery rate is good. The method can be used to determine the migration of 1,4-butanediol in food contact materials through the investigation of the method
