Physical-Chemical Composition of Raw Milk Produced by Small Producers of the Itamarati-MS Settlement

Abstract

This study aimed to evaluate the physicochemical characteristics of raw milk produced by small producers in the Itamarati Settlement. The samples were collected in 10 different rural properties 3 times a week, during the month of July 2021, by students and teachers of the Faculty of Agrarian Sciences and placed in 1000 ml polyethylene pots and identified with numbering from 1 to 10 and transported under refrigeration in isothermal boxes containing ice sheets until the Food Technology Laboratory -TPA, of the Federal University of Grande Dourados (FUGD), to carry out the physicochemical analyzes such as alizarol stability, titratable acidity, relative density and cryoscopic index, fat, protein, defatted dry extract and defatted dry extract. After the analyzes were carried out, a visit was made to the Itamarati Settlement, with the producers, respecting all safety measures due to Covid-19, where the results were found in relation to the physical and chemical quality of the collected samples were presented and, afterward, they were discussed. if how this can influence the quality of milk and consequently the income of producers. Through the physical-chemical analysis, it was possible to identify that 90% of the analyzed samples were in accordance with the norms of IN 62, for all analyzed variables. Monitoring the quality of the producers' milk is of paramount importance because in many rural properties milk is the main source of income in some of them, it is even the only source of income for producers and their families.
