Resumen
A defumação é um processo rotineiramente empregado nos alimentos como técnica de conservação, e uma maneira de proporcionar as características sensoriais específicas. Entretanto, o processo pode levar à formação de hidrocarbonetos policíclicos aromáticos (HPAs), que são compostos com dois ou mais anéis aromáticos condensados, alguns deles considerados carcinogênicos, mutagênicos e teratogênicos. Estudos em diversos países indicam que a contaminação de produtos cárneos defumados por diferentes HPAs é elevada e frequente, e desta maneira pode apresentar risco à saúde humana. O Brasil tem sido um dos maiores consumidores de carne no mundo, com tendência de aumentar o consumo de alimentos processados, e não é conhecida a real exposição da população aos HPAs pela ingestão de produtos cárneos defumados. Não há dados nacionais recentes quanto à contaminação destes alimentos com estes produtos. Considerando este panorama, o presente trabalho tem como objetivo realizar a revisão das principais metodologias analíticas, dos aspectos regulatórios e dos níveis de HPAs detectados em produtos cárneos defumados. Ademais, são apresentadas as maneiras de reduzir a contaminação dos alimentos por estes compostos.
