Chemical and physical characteristics of local lecithin in comparison with some other food emulsifiers

Abstract

The chemical and physical characteristics of local lecithin and other food emulsifiers (Emulfuid E, Triodan R 90, Panodan 150 and Glycerol mono stearate) were studied. The characteristics of these emulsifiers studied were solubility, hydrophile-lipophile balance (HLB), stability index (SI), fatty acid composition and infrared spectrum. The results obtained showed that Emulfuid E and local lecithin were mixture of lecithins and phosphatidyl ethanol-amine. In addition, Triodan R 90 was a polyglycerol ester of ricinoleic acid, Panodan 150 was a blend of mono and diglycerides, and G.M.S. was a monoglycerol ester of stearic acid.
