Study of Some Physical Properties of Fresh, Frozen and Rendered Animal Fats

Abstract

The chemical compositions (moisture, protein, fatandash) of sheep, cows,buffaloes and camels, fat and their chemical characteristics and minerals, cholesterol,lipoproteins and phospholipids content has been studied, Cholesterol content wasestimated the highest values of cholesterol was in cows fat from the Hartha area ,amounting 203 mg / g and the lowest concentration were, amounting 158 mg / g inmutton fat tail of Qurna area sheep. Estimated concentrations of lipoproteins of sheep,cows, buffaloes and camels fat VLDL and LDL and HDL by the Rflatron device Theconcentrations are as follows (19.32, 13.70, 10.00) and (18.80, 10.40, 9.70) and (19.40,11.90, 11.60) and (19.20, 9.80, 12.30 ) in the lipids of sheep, cows, buffalo and camelsrespectively. In the lipids of sheep, cows, buffalo and camels the highest concentrationofPhosphottidylCholine of camels fat was 27.70 μg/100gm and the lowestconcentration in cows fat (14.63μg/100gm) and the highest concentration ofPhosphotidylinsito in camels fat was12.24 μg/100gm and the lowest concentrationinthe cows fat (5.56 μg/100gm) and for PhosphotidylEthanolaminthe highestconcentration was in camels (12.87 μg/100gm) and the lowest in cows fat( 5.86μg/100gm) the highest concentration of Phosphotidyl Serine in sheep fat (10.69) and thelowest was in camels fat (2.10 μg/100gm).
