Abstract
A rapid fat method was developed for routine analysis of dairy wastewaters. The new method using ammonium hydroxide to dissolve the protein and ethyl and petroleum ether for fat extraction proved superior to the standard Soxhlet method using hexane or trichlotrifluroethane as extracting solvents. From 1 to 5% more fat was recovered by the rapid fat method than by the Soxhlet method using hexane. Test results can be obtained in 1.5 h as compared to 6 h for the Soxhlet method. Equipment required for the rapid fat method is available in most dairy plants.This publication has 0 references indexed in Scilit:
