La creciente importancia de la avicultura en la Provincia de Entre Ríos (Argentina) hace necesario profundizar en el conocimiento de esta industria. En este caso, el almacenamiento constituye un factor clave para mantener la calidad de las carnes durante la cadena de distribución. El objetivo de este trabajo fue evaluar el efecto de distintas condiciones de conservación sobre los parámetros de calidad de fillets de pechugas de pollos, simulando su comercialización en mercado interno y exportación. Se determinaron: pH, terneza, mermas por cocción y color a fillets marinados y sin marinar, conservados en refrigeración durante 4 días y en congelación 90 y 180 días. Los resultados indican que la terneza y las mermas por cocción no se modificaron por efecto de las condiciones de conservación estudiadas, sólo se observó un mayor valor de pH y de la coordenada a* en fillets luego de 180 días en congelación.

The rising importance of poultry production in Entre Ríos (Argentina) makes necessary a deeper knowledge of that industry. In this case, storage is a key factor in maintaining the quality of meat during the distribution chain. The aim of this study was to evaluate the effects of different storage conditions on quality parameters of poultry breast fillets, simulating marketing in the national and international market. Marinated and no marinated fillets were stored at refrigeration temperature for 4 days and at freezing temperature during 90 and 180 days; pH, tenderness, cooking loss and color were determined. The results indicate that tenderness and cooking loss are not modified by the storage conditions studied. Only higher pH and a* values were registered in fillets after 180 days at freezing storage.The rising importance of poultry production in Entre Ríos (Argentina) makes necessary a deeper knowledge of that industry.

A crescente importância da avicultura na Província de Entre Rios (Argentina) faz necessário aprofundar os conhecimentos desta indústria. Neste caso, a armazenagem é um fator fundamental para manter a qualidade das carnes durante a cadeia de distribuição. O objetivo deste estudo foi avaliar o efeito de diferentes condições de conservação sobre os parâmetros de qualidad de filés de peito de frangos, simulando sua comercialização no mercado interno e exportação. Foram determinados: pH, maciez, perdas por cozimento e cor a filés marinados e sem marinar, conservados em refrigeração durante 4 dias e em congelamento 90 e 180 dias. Os resultados indicam que a maciez e as perdas por cocção não foram modificadas pelo efeito das condições de conservação estudadas, apenas se observou um aumento do valor do pH e da coordenada a* em filés após 180 dias em congelamento.
