Composition of Pork Bellies. I. Specific Gravity as a Predictor of Chemical Composition1

Bruce G. Schroder2 and R. E. Rust

Iowa State University3, Ames 50010

Abstract

Specific gravity of pork bellies was tested to determine its usefulness as a nondestructive predictor of percentage moisture, fat and protein. Correlations between specific gravity and percentage moisture, fat and protein were r = 0.85, r = –.83 and r = 0.83, respectively, and highly significant (P< .01).

Regression equations for each of the three composition variables were determined. These regression equations were tested and proven unreliable due to the large standard error of the estimate. Thus the use of specific gravity for predicting the chemical composition of pork bellies was found not to be of use at this time.
