PROXIMATE COMPOSITION AND MINERAL ANALYSIS OF GOAT’S LIVER, COW’S PANCREAS AND THEIR MEAT STOCK

Abstract

The study was carried out to determine the proximate composition as well as the concentration of Na, K, Ca, Mg, Fe, Zn, Mn, Cu, Ni and Pb in goat’s liver, cow’s pancreas and their meat stocks as few or no researches have been conducted for the samples under investigation.. The standard procedures of AOAC (1990) were followed to determine the proximate composition while the mineral analyses were carried out using Atomic Absorption Spectroscopy (AAS). The mean moisture content for goat’s liver, cow’s pancreas, stock from goat’s liver and stock from cow’s pancreas ranged between 19.66±0.20, 19.17±0.14, 12.00 – 19.66 % while the protein content is in the range of 40.38 – 51.2 %, also 26.1 – 32.26 % for crude fat and lastly 2.35 – 15.05 for ash content. Crude fibre and carbohydrate were absent in the meat sample. The level of the minerals in the meat products ranged between 38.30 -144 mg/kg for Na; 95.60 – 182.50 mg/kg for Ca; 21.20 – 77 mg/kg for K; 4.51 – 4.94 mg/kg for Mg; 2.00 – 30.00 mg/kg for Fe; 0.32 – 5.95 mg/kg for Cu; 0.97 – 1.54 mg/kg for Mn; 1.83 -6.25 mg/kg for Zn; 0.01 – 0.30 mg/kg for Pb and 0.01 mg/kg Ni for all the four samples.  The results indicate that goat’s liver, cow’s pancreas and their meat stock contains high level of protein and fat. The concentrations of the trace elements were below tolerance limit. Therefore, it was concluded that the meat product has high nutritional value and safe for human consumption.
