Artisanal Minas cheese parameters associated with regions of origin in Minas Gerais, Brazil

Abstract

Artisanal cheese production involves a centuries-old tradition in the state of Minas Gerais in Brazil, playing an important historical and social role. The aim of this study was to evaluate the characteristics of artisanal Minas cheeses from seven regions certified for their production in relation to their physicalchemical and centesimal composition to identify parameters that are useful to differentiate them. There were differences among the cheeses from different regions for the soluble nitrogen variables, extension and depth of ripening indexes, ash, oxidation, fat and pH. The highest values for the ripening length and depth index were observed in the Cerrado region. The cheeses from the Canastra region were different due to the higher moisture content, and the cheeses from Campo das Vertentes presented higher pH and nitrogen compound values. Despite the similarities among cheeses in each region, they had dispersed positions in the principal components analysis. There are differences in the physicochemical and centesimal composition among the artisanal Minas cheeses from the distinct regions in Minas Gerais, and the analyzed parameters can be used to differentiate them. The contents of ash, fat, oxidation index, soluble nitrogen and pH were the parameters that were associated with greater differences in cheeses.
