PROCESS FOR PREPARING AN ACETOGLYCERIDE COMPOSITION COMPRISING HIGH AMOUNTS OF MONOACETYL MONOACYL GLYCERIDES

摘要

The present invention relates to a process for preparing an acetoglyceride composition comprising a high amount of monoacetyl monoacyl glycerides wherein a reaction mixture comprising long chain fatty acid moieties, glycerol moieties and short chain carboxylic acid moieties is contacted with a catalyst. The reaction mixture is allowed to reach equilibrium and optionally the equilibrium is shifted by removing the most volatile component or components from said reaction mixture. After the reaction is completed, the catalyst is deactivated followed by purification of the reaction mixture by separation of said reaction mixture into an acetoglyceride fraction and one or more non-acetoglyceride fractions. The molar ratio of the long-chain fatty acid moieties and the glycerol moieties in the reaction mixture is between 1:8 and 1:3 and the molar ratio of the short chain carboxylic acid moieties and the glycerol moieties in the reaction mixture is between 1.5:1 and 3:1.
