| The purpose of this study was to form new dispersion systems based on chemically interesterified waste turkey fat containing sesame oil (2:3 wt./wt.) and to evaluate effectiveness of synthetized diacylglycerols stabilizing these emulsions. Sesame oil was used to enrich and improve turkey fats composition with unsaturated fatty acids derived from oil. Physical properties of raw fats and fat blends (before and after the reaction) were determined. Increase of acid value and crystallization point was noted after the reaction, and no changes occurred in the fatty acid composition of the sesame oil and turkey fat blends. Diacylglycerols were synthesized from specified monoacylglycerols, then purified, and analyzed by means of Gel Permeation Chromatography (GPC) and Thin-Layer Chromatography (TLC). The role of the amount of synthetically obtained diacylglycerols (DAG) as emulsifiers in obtaining the stable emulsion product was examined. 6% (wt./wt.) was found to be the smallest amount of DAG emulsifier needed to properly stabilize the prepared emulsions. The proposed new emulsion products could be applied as new food product formulations like mayonnaise sauces or dressings. Such formulations containing beneficial fats like turkey fat or sesame oil, as well as new structured diacylglycerols could meet customer requirements. |
