2.4. Bone and meat fractions
Bone and meat fractions of MBM samples were determined by the flotation method described by Khajarern and Khajarern(1999). Meat and bone meal sample (10 g) were weighed in beaker and mixed well with carbon tetrachloride (90 ml) todissolve the fat. The samples were then allowed to settle, and the floating meat and submerged bone fractions were separatedon separate filter papers (Whatman no. 4). Both fractions were dried at 110◦C for 10 min, allowed to cool and weighed tocalculate the proportions of bone and meat fractions
