液相色谱串联质谱法测定食品中甘露糖醇、麦芽糖、木糖醇、山梨糖醇
Determination of mannitol, maltose, xylitol, sorbitolin in foods by LC- MS/MS method
摘要
Abstract
Natural sweeteners extracted from natural plants, in safety and nutrition function far better than synthetic sweeteners. In this paper, liquid chroraatography - tandem mass spectrometry was used to determine mannitol, maltose , xylitol, sorbitolin of the residues in food, using selected ion monitoring for positive confirmation. Liquid sample is extracted with water by the ultrasonic processor, After centrifugation and volume, Solid samples or hemi - solid samples were dissolved constant volume of water, and then by HLB solid phase extraction cartridges, eluted sample solution was determined later for the determination and confirmation by LC - MS/MS using external standard method. The detection limits, linear ranges, and recoveries of this method, for mannitol, maltose, xylitol, sorbitolin, are 0. 10mg/kg、 0. 10 ~ 1000. 0mg/kg and 89. 0 ~94. 9% . This study established a method for determination of mannitol, maltose, xylitol, sorbitolin in foods, can quickly and sensitive, a simultaneous determination of many categories and natural sweeteners and its positive categories confirmation. Also is to break the foreign technical barriers to trade, enhance Chinas export products in the international market competition ability to provide strong guarantee.关键词
