More Information
Summary:PURPOSE: To provide the subject composition composed of a polyglycerol fatty acid ester having low free polyglycerol content and fatty acid alkali metal salt content, exhibiting excellent O/W-type emulsifying power even under acidic condition or high-salt concentration condition, having excellent stability and useful as a food emulsifier, etc. CONSTITUTION: This composition is composed of (A) a polyglycerol fatty acid ester having an average esterification degree of 20-30mol%, especially 22-27mol%, (B) <=35wt.% of a free polyglycerol and (C) <=0.2wt.%, especially <=0.05wt.% of a fatty acid alkali metal salt. The composition can be produced e.g. by esterifying a polyglycerol having a polymerization degree of 6-12 with a 12-22C fatty acid in the presence of 0.001-0.025wt.% (based on the total raw materials) of an alkali catalyst at 200-240 deg.C and continuing the reaction by further raising the temperature by 20-60 deg.C when the conversion of the fatty acid reaches >=70%.
