Comparison of Two Milk Fat Extraction Methods for Pesticide Residue Analysis

Abstract

Results, based on 38 comparisons, indicate that in the analysis of two organochlorine insecticides (heptachlor epoxide and dieldrin) in milk the fat recovery can be made with a surfactant method. This is faster, less expensive, and easier than the modified Roese-Gottlieb extraction commonly used. © 1967, American Dairy Science Association. All rights reserved.
