Analyses of Monoglycerides and Other Emulsifiers by Gaschromatography

GLC‐analysis has become a still more important tool for the analysis of many emulsifiers and is a powerful supplement to the chemical method for describing an emulsifier. The autosampling technique has made GLC more reproducible which is necessary for quantitative analysis. The new generation of gas chromatographs with computer connection is a good and almost necessary help for calculation of the sample composition and has opened up possibilities for more information. Methods and examples are described for the analysis of monoglyceride, lactic acid esters of monoglyceride, acetic acid esters of monoglyceride, and propylene glycol esters of fatty acids. For more complicated separations of components in emulsifiers capillary columns can be used with good results.
