Fat Extraction from Acid and Base Hydrolyzed Food

2017 12 15  This paper describes a new in cell method for pursuing accelerated solvent extraction (ASE) prior to lipid analysis from food samples. It is difficult to pursue direct ASE with acid or base hydrolyzed samples due to the corrosive nature of the reagents and material limitations. In this study ion exchange based materials were used to remove acid or base reagents in cell without compromising
