Summary: | This study aimed to evaluates some physical chemical aspects of chilled raw milk that meet Brazilian quality standards in smallholder farms from southern Region of Brazil. The fat content, crude protein (CP), total solids (TS), somatic cell count (SCC), and total plate count (TPC) of the chilled raw milk from 78 smallholder farms was analyzed between Oct 2014 and Feb 2017. It was found that 96% of the samples met the Brazilian regulations for fat content, 87% for CP, and 91% for TS. The mean values of TPC and SCC were higher than the maximum limits established by Brazilian regulations. Smallholder farms from Southern Region of Brazil produce milk with an adequate standard for the main chemical indicators. However, there is an important gap in compliance with hygienic-sanitary practices, leading to high levels of chilled raw milk that does not meet the limits of Brazilian regulations. Key words: somatic cell count, total plaque count, fat. Objetivou-se avaliar alguns padroes fisico-quimicos do leite cru refrigerado em relacao ao atendimento aos padroes de qualidade brasileiros em pequenas propriedades da Regiao Sul do Brasil. O teor de gordura, proteina bruta (PB), solidos totais (ST), contagem de celulas somaticas (CCS) e contagem total em placas (CTP) do leite cru refrigerado de 78 pequenas propriedades foram analisadas mensalmente entre outubro de 2014 e fevereiro de 2017. Verificou-se que 96% das amostras atenderam as regulamentacoes brasileiras para teor de gordura, 87% para PB e 91% para ST. Os valores medios de CTP e CCS foram superiores aos limites maximos estabelecidos pela regulamentacao brasileira. Pequenas propriedades da Regiao Sul do Brasil produzem leite com adequado padrao para os principais indicadores quimicos. No entanto, existe uma lacuna importante no cumprimento das praticas higienico-sanitarias, levando a altos niveis de leite cru refrigerado que nao atendem os limites da regulamentacao brasileira. Palavras-chave: contagem de celulas somaticas, contagem total emplaca, gordura. |
