SIMPLIFICATION OF THE ANALYSIS OF DRY MATTER IN FLUID MILK

Abstract

This study aims to evaluate a simpler methodology for determining dry matter using three types of milk. The treatments consisted of three methodologies: official (AOAC), characterized by the drying in porcelain capsules and pre-heating; use of analytical sand in the process of drying, as well as a simplified methodology characterized by drying in Petri dishes without analytical sand (simplified methodology). The statistical analysis was performed with F test (5% significance level), Pearson’s correlation and Lin's concordance correlation coefficient. All methodologies showed precision and accuracy in the measurement of the dry matter in milk, however, the simplified methodology was superior in material savings and shorter time consumption for the analysis.
