Determination of Fat in Meat and Separable Fat by the Gerber Test

Abstract

A modified Gerber fat test for the determination of fat in meat and separable fat is described. A factor of 0.935 is applied to correct for the difference between the S.G. of butterfat and body fat. Average recovery of purified animal fat was 99.9 per cent. Samples containing more than 3 per cent fat showed lower variability with the Gerber test than with the solvent extraction method. For routine work on animal tissue and fat the Gerber test was found to be more rapid and reliable than the solvent extraction method. © 1963 Taylor & Francis Group, LLC. All rights reserved.
