Avaliação da qualidade da carne da carpa húngara Cyprinus carpio de diferentes sistemas de cultivo na Região Sul do Brasil.
From the Asiatic continent, the carp has been cultured in China for more than 2.000 years, but it came to Brazil only in 1904. Among the different forms of fish cultivation, the integrated system with other animals has been mass utilized, possibly because of the low production costs. So, the carp cultivation with chicken and pig manure has been much used in South Brazil, especially in Rio Grande do Sul. The present work has the aim to analyze the effects of these cultivation systems on the minced quality. It was divided in two chapters. In the first we studied the influence of the systems of cultivation of carps fed with ration, grew with pig manure and with chicken manure on the minced quality of Hungarian carp Cyprinus carpio. In the second the effect of the transport method was evaluated on the minced of carps that were fed with ration, grew with manure of pig and chicken. The minced was processed minimally, vacuum wrapped in polyethylene and conserved under refrigeration 2±1ºC until the moment of the analysis. To evaluate the influence of the cultivation systems and the effect of the transport method on the minced of Hungarian carp analyses of carcass revenue and the proximal composition of the muscle and the minced were made. The analyses of TVB (total volatile bases), pH, PI (peroxides index) and TBA (acid thiobarbituric) in minced were analyzed on the 1st, 4th, 7th, 15th and 30th days conservation. In the first chapter the results show that in spite of the small differences found in the analyses, it is quite evident that one cannot affirm that the transport methods present differences in the minced (either transported alive or in the ice). In relation to the second chapter, chicken manure possibly present a protein quality worse in comparison with other treatments.
