RESUMO
The objective of this work was to evaluate the influence of vacuum application and partial replacement of NaCl with KCl in the manufacturing of ready-to-eat charque with low sodium content. The application of four vacuum pulses (4VP) resulted in greater salt reduction and lesser water gain when compared to the desalting process conducted at atmospheric pressure (Patm). In addition, the vacuum-assisted desalting contributed to a more homogeneous salt distribution in the product. The time required for the samples to reach an approximate NaCl concentration of 2.5% in the desalting stage was 48 h, regardless of the process conditions. The initial Na+ concentration was reduced by 50% with the replacement of NaCl with KCl in both process conditions (either Patm or 4VP) when compared to charque traditionally desalted.
RESUMO
The aim of this study was to compare the vacuum and air cooling of cooked chicken breast samples arranged in stacks with one, two and three layers (1 kg per layer). The cooling rate obtained with vacuum cooling was approximately three times faster than that of air cooling. Moreover, a more homogeneous cooling was obtained with vacuum cooling, with similar temperature reductions for samples at different positions of the stack. On the other hand, vacuum cooling led to mass losses of 11-12%, while air cooling led to losses of 7-8%. The counts of mesophiles and psychrophiles of the vacuum-cooled samples were lower than those observed for air-cooled samples after ten days of product storage. Thus, the results presented in this work illustrate the potential benefits and disadvantages of the vacuum cooling technique as compared to the air cooling, especially for the processing of small meat cuts.
RESUMO
Relata-se a ocorrência de dois casos de pseudotumor inflamatório na bexiga de cäes, enfatizando a importância de reconhecer o caráter benigno dessas lesöes, evitando uma abordagem terapêutica agressiva como conseqüência de um diagnóstico equivocado
