Horse fat was vacuum-extracted from fatty tissues of Jeju and Halla horse meat and their physicochemical properties were compared to those of commercial lard and beef-tallow. For color, ΔE was found to be decreased when crystallized. Although acid values of horse fat were higher than those of lard and beef-tallow, p-anisidine and totox values were lower. The iodine value of beef-tallow was the lowest (44.61), and those of horse fat and lard were similar (57.53- 57.74). Only horse fat contained α-tocopherol. The contents of γ-tocopherol in Jeju and Halla horse fat, lard, and beeftallow were 7.08, 4.57, 2.13, and 1.91 mg/kg, respectively. Palmitoleic acid (C16:1) was found in horse fat. Melting and crystallization curves of horse fat displayed two endothermic and exothermic peaks which were differentiated from lard and beef-tallow. These results indicated that horse fat demonstrates different physicochemical properties compared to lard and beef-tallow, when applied to various types of lipid products.
