The grated Parmesan cheese is among the most consumed cheese in the country and also among the most fraudulent, since the fragmentation facilitates the incorporation of various adulterants. Brazilian law establishes as the parameters to be evaluated in grated cheese only the moisture content and the fat content in dry matter (GES). However, it is important to analyze other parameters, in order to characterize the products commercialized in Brazil, as quality can be compromised. The objective of this study was to analyze the chemical composition and presence of starch in different samples of grated Parmesan cheese, commercialized in the city of Paranavaí, Paraná. Fifteen samples were analyzed, being three different batches of five brands. The chemical composition (moisture, ash, carbohydrates, proteins and lipids) differed from one sample to another; however, all samples were in compliance with Brazilian legislation, considering the moisture content. For the GES content, 60% of the samples showed values higher than those established by Brazilian legislation for semi-fat cheese, such as grated Parmesan cheese. One sample showed a high carbohydrate content, however, starch was not detected by the lugol test. It is concluded that 60% of grated cheese commercialized in the city of Paranavaí present disagreement with Brazilian law, because they had higher fat content in the dry matter than the established.
