| The aim of this work was to obtain and evaluate the stability of new emulsion systems, in which diacylglycerols derived from enzymatic interesterification of mutton tallow with hemp oil were used as emulsifiers. In order to achieve a higher content of the polar fat fraction in the final fat blend, a different amount of water was added to the reaction mixtures. The modified fats with a mixture of mono and diacylglycerols served as a fat base for emulsions. Based on the results of Turbiscan test, the droplet size, emulsion texture, and studies of rheological properties, it was found that addition of water to the reaction mixture in the range of 1.00-1.25%, wt./wt., caused the formation of a sufficient amount of emulsifiers stabilizing the dispersion system.The novelty of this work was to determine the optimal amount of water added to the interesterification of mutton tallow with vegetable oil, ensuring the synthesis of a high-efficiency emulsifying system. Another new aspect of this work was to show that the diacylglycerols obtained during such fat modification constitute effective emulsifiers for new stable emulsion systems that may find potential use as food emulsions (dressings) or cosmetic products dedicated to sensitive skin.
