| In the present study, composition, functional properties and sensory characteristics of Mozzarella cheese produced from milk with somatic cell counts (SCC) at low (<200,000 cells/mL), intermediate (≈400,000 cells/mL) and high (>800,000 cells/mL) levels were investigated. Three batches of cheese were produced for each SCC category. The cheeses were vacuum packed in plastic bags and analysed after 2, 9, 16, 23 and 30 days of storage at 4ºC. SCC level did not affect the moisture, fat, total protein and ash content, mesophilic and psychrotrophic bacteria, and sensory parameters of Mozzarella cheese. However, meltability increased in cheese manufactured from high SCC milk. Results indicated that raw milk used to produce Mozzarella cheese should not... |

| A ocorrência de aflatoxina B1 (AFB1) em rações e aflatoxina M1 (AFM1) no leite cru foi avaliada em propriedades leiteiras situadas na região nordeste do Estado de São Paulo, Brasil, de outubro de 2005 a fevereiro de 2006. A análise de aflatoxinas foi efetuada utilizando-se colunas de imunoafinidade para purificação dos extratos, sendo a quantificação realizada através de cromatografia líquida de alta eficiência. A AFB1 foi detectada em 40% das rações em níveis de 1,0 a 19,5 μg.kg-1. A concentração de AFM1 em 36,7% de amostras de leite positivas variou de 0,010 a 0,645 μg.L-1. Somente uma amostra de leite estava acima do limite de tolerância adotado no Brasil (0,5 μg.L-1) para AFM1. Concluiu-se que as concentrações de aflatoxinas na ração e no leite foram... |

| The objective of this work was to evaluate the effects of using bulk milk with different somatic cell counts (SCC) on the quality of minas frescal cheese. A randomized complete block design was used, with 3x5 factorial treatments, with three SCC levels (low, 125,000 cells mL-1; intermediate, 437,000 cells mL-1; and high, 1,053,000 cells mL-1) and five storage durations. Cheese was vacuum-packed in plastic bags and analyzed after 2, 9, 16, 23 and 30 days of storage at 4ºC. Somatic cell counts did not affect dry matter, fat, ash content, pH, free fatty acid concentrations and sensory parameters of minas frescal cheese. However, SCC in milk increased losses of protein in whey and decreased the cheese protein content. These changes did not affect the... |

| The objective of this work was to evaluate the effect of somatic cell counts (SCC) in casein fractions of ultra high temperature (UHT) milk. Raw milks were categorized in SCC groups of low (200,000-320,000 cells mL-1), intermediate (380,000-560,000 cells mL-1) and high cells (600,000-800,000 cells mL-1). Five replicates of UHT milks within each SCC category were analyzed for casein fractions after 8, 30, 60, 90 and 120 days of storage through high performance liquid chromatography. SCC showed effect only on beta-casein reduction. SCC in raw milk increases the proteolysis of UHT milk, as a consequence of beta-casein degradation. |
