摘要：Tallow samples were obtained form the local slaughterhouses and were evaluated for iodine value, saponification value, anisidine value, acid value, peroxide value, FFA, ash content and cholesterol content. The results were compared with that of Codex standard for the edible animal fats. The acid value of tallow was 1.009-1.99 mg KOH/g. The saponification value (195-197 mg KOH/g) indicate that the tallow contain high molecular weight fatty acid s. The iodine values (48.66-49.15) suggest a low degree of unsaturation compared to palm oil. The FFA, AnV and POV were 0.507-1.00 (as oleic acid %by wt.), 6.33- 9.57 and 3-6.5 (meq / kg) respectively. The cholesterol and %ash content were in the range of 1.00-1.10 (mg/g) and 0.183-0.57, respectively. In minerals, the level of Na is 10.037-18.952 ppm, K (2.216-2.821 ppm), Ca (1.123-1.752 ppm), Cu (0.001 ppm), Fe (0.430-0.493 ppm), Pb (1.147-1.153 ppm), Mg (0.412-0.473 ppm), Cd (0.070-0.071 ppm), Zn (0.028-0.055 ppm) and Cr (0.896-0.982 ppm).
