Efeitos da composição físico-química e higiênico-sanitária do leite na produção de queijo minas padrão

Abstract

The modern consumer demand indicates that, to compete in the international and globalized world, especially in dairy market, it is required good quality of the raw material. The milk quality can influence income and food safety and it depends on the hygienic-sanitary care of the dairy herd. There is a concern that low milk quality can reduce industrial yield, as well as change flavor of products or even reduce their shelf life. The present study aimed to evaluate the effects of the physic-chemical composition and hygienic-sanitary quality of milk on the production of Standard Minas Cheese made from raw milk. There was no association between somatic cell count (SCC) and chemical components of Standard Minas Cheese produced. The hygienic-sanitary indicators did not influence the weight of the cheese produced. However, there was association between weight of milk components and weight of cheese. Variations were observed in cheese weight according to changes in fat, protein, dry skimmed extract and total dry extract weights. There was also a direct association between SCC in milk and fat and protein of the whey. The sample size may have influenced the results and the predictive power of the model. The coefficients of determination need more detailed research in the future.
