Resumen
O efeito da radiação ionizante em coxas de frango cruas embaladas a vácuo e sob atmosfera modificada e armazenadas a 4±1 ºC foi avaliado a partir da análise de substâncias reativas ao ácido tiobarbitúrico (TBARS). Para amostras embaladas a vácuo foram observados aumentos gradativos nos valores de TBARS conforme o aumento da dose de radiação ionizante para os diferentes dias de armazenamento, porém as diferenças não foram significativas (p>0,05) até o 14º dia quando os respectivos períodos foram comparados. Amostras irradiadas com 1,5 kGy e 3,0 kGy e embaladas sob atmosfera modificada apresentaram valores de TBARS significativamente (p<0,05) menores em relação às respectivas amostras embaladas a vácuo, exceto no 20º e 26º dia de armazenamento. Os maiores valores de TBARS foram obtidos para as amostras irradiadas com 7,0 kGy com médias de 2,13 e 1,52 mg.kg-1 de malonaldeído em embalagem a vácuo e sob atmosfera modificada respectivamente.Citas
