Beta Radioactivity of the Ash in Relation to the Composition of Ham

U. S. Department of Agriculture^{1, 2, 3,}

Abstract

The results of a study in which measurements were made of the beta radioactivity emitted by the ash of ham fat trimmings samples and samples with variable proportions of ham lean and fat trimmings from 34 hogs are presented. There is evidence of a relationship between the amount of beta radioactivity emitted, expressed on a fresh weight basis, and the percent of fat-free lean (fresh basis). Data pertaining to the correlation of beta radioactivity and the content of ether extract, protein and moisture in these samples are presented.
