Influência da inspeção sanitária na qualidade físico-química do queijo de coalho

Abstract

This study aimed to evaluate the influence of sanitary inspection on the physicochemical characteristics, colour and texture of coalho cheese commercialised in the semiarid region of Brazil. One hundred and thirty-eight coalho cheese samples from commercial establishments in 46 Brazilian cities were evaluated, and physicochemical analyses (acidity, moisture, fat content, pH and ashes), as well as colour and texture tests were performed. The averages for the parameters in cheeses without the official sanitary inspection seal were 4,31, 0.34%, 50.34%, 55.9 and 4.83, for ash, relative acidity, moisture, fat content and pH and in samples with the official sanitary inspection seals we found values of 4,41, 0.32%, 51.51%, 55.37 and 4.92, for the same parameters, respectively. There was no difference in the colour and texture parameters, which for the samples with the official seal were 71.15, 1.43, 13.52 and 1.65; and for the ones without the official seal were 69.58, 1.50, 13.15 and 1.71 for L*, a*, b* and texture, respectively. The fact that the coalho cheese was commercialised with an official inspection seal did not influence the physicochemical, texture or colour analyses.
