Abstract
Monoheptadecanoin (monomargarin) has been used as an internal standard for the gas‐liquid chromatography (GLC) determination of monoglyceride and propylene glycol ester emulsifiers. The compound is expensive and difficult to prepare. Octadecyl glyceryl ether (batyl alcohol), a less expensive commercially available material, has been found to be acceptable as an internal standard for this determination.
