Composition of shark meal

, : Composition of shark meal. Jour Agric Res 76-(9/10): 213-218

Analyses are reported from studies of 19 samples of commercial shark meal processed from sharks caught off the Florida coast. The presence of urea and additional non-protein N, called nitrogen fraction A, resulted in excessive crude protein values. Average values were: water, 9.18; crude protein, 78.07; ether extract, 2.8; crude fiber, 0.32; ash, 13.97; Ca, 3.48; P, 1.92; and Mg, 0.17%. Seventeen samples averaged 1.75% of urea and 0.49% of nitrogen fraction A. Spectro-graphic analyses showed Ca, P, Na, Mg, Si, Fe, Sr, Mn, Zn, Pb, Cu, B and Ba present in 12 samples, Sn in 8, Ni in 3, and Cr in 2 samples.

It is known that anaphylactic mediators induce blood-coagulation, which results in thrombus-formation in the place of the anaphylactic reaction. This thrombus is likely to mask the antigen which induced the anaphylaxis, thus protecting it from fur...
