Efeito da embalagem em atmosfera modificada sobre a validade comercial de filé de tilápia nilótica (Oreochromis niloticus)

Abstract

O objetivo deste trabalho foi determinar o efeito da Embalagem em Atmosfera Modificada (EAM) sobre a validade comercialde file fresco de tilapia nilotica estocada sob refrigeracao de 5±1°C. Ao longo de 22 dias de estocagem, realizou-se acontagem de bacterias heterotroficas aerobias mesofilas, analise de pH e analise sensorial de files de tilapia submetidosaos tratamentos de ar atmosferico (100%), vacuo, 50/50 CO2/N2 e 100% CO2. Os resultados foram tratados estatisticamenteatraves de analise descritiva simples. As contagens bacterianas dos tratamentos 100% ar, vacuo e 50/50 CO2/N2 chegarama niveis >log 8,0 UFC/g nos dias 6, 16 e 12, respectivamente. No tratamento com EAM 100% CO2 as contagens mantiveramseentre log 2,8-4,1 UFC/g. O pH diminuiu com o tempo de estocagem em todos os tratamentos, estando sempre dentro dospadroes permitidos (d”6,5). O atributo cor foi alterado significativamente pelos tratamentos com CO2, sendo que no vacuo acor manteve-se normal por mais tempo. Pode-se concluir que a EAM com 100%CO2 apresentou melhores resultados noaumento de validade comercial de files de tilapia estocados a 5°C, mantendo a contagem de mesofilos e valores de pH emniveis aceitaveis durante todo o periodo de estocagem de 22 dias.
