Abstract

The aim of this work was to develop a new fat by enzymatic interesterification of mutton tallow with rapeseed oil. It was assumed that by inducing hydrolysis of fats by addition of water to the enzymatic preparation (8, 10, 15 wt%) natural emulsifiers would be produced in the reaction environment. Fat blends obtained from the enzymatic reactions were evaluated as a fat base for emulsion systems. It was found that the fat resulting from interesterification in the presence of Lipozyme RM IM (immobilized lipase from Rhizomucor miehei, Novozymes Bagsvaerd, Denmark) with 15 wt% of water possessed the highest content of polar fraction (MAG and DAG), and served as the most suitable blend for emulsification, producing emulsions that exhibited the highest stability.
