Determination of dimeric glycerol in monoglycerides by HPLC.
New regulations limit the amount of diglycerol that may be present in partial glycerides used as food emulsifiers. Dimeric glycerol can be easily determined by HPLC on silica columns using acetonitrile: water partition and RI detection. Results for free diglycerol and total diglycerol obtained with a number of monoglyceride samples are given.
