Evaluation of Fructooligosaccharides and Inulins as Potentially Health Benefiting Food Ingredients by HPAEC-PED and MALDI-TOF MS
fructooligosaccharides electrochemical detection anion exchange mass spectrometry
2009/9/4
This paper describes the complementarity of high-performance anion exchange chromatography coupled with pulsed electrochemical detection (HPAEC-PED) and matrix-assisted laser desorption/ionization mas...
以含镉(Cd)500 μg/L水体中养殖0, 10, 20 d的3组鲫鱼为研究对象, 测定鱼肉中Cd含量， 借助HPLC与MALDI-TOF-MS离线联用技术得到鱼肉磷脂图谱, 并采用偏最小二乘判别分析法(PLS-DA)针对图谱数据开展模式识别分析. 结果表明, 在20 d暴露期内, 鱼肉中Cd含量呈持续上升趋势, 而磷脂酰胆碱(PC)含量在暴露10 d后显著低于正常水平(未受镉暴露)(p<0.0...
