Chá-mate e café como fontes de hidrocarbonetos policíclicos aromáticos (HPAs) na dieta da população de Campinas

Abstract: .br * A quem a correspondência deve ser enviada. RESUMOCom o objetivo de determinar os níveis dos contaminantes hidrocarbonetos policíclicos aromáticos (HPAs) em chá-mate e café e avaliar a contribuição desses produtos como fonte de HPAs na dieta da população de Campinas, três marcas com três diferentes lotes de chá-mate e café em pó, totalizando 18 amostras, foram analisadas. Os dados de consumo de chá-mate e café foram obtidos de uma pesquisa de hábitos alimentares feita no ano de 1993 junto à população loca… Show more

“…1,13 Studies conducted in Brazil and in many other countries have identified specific food categories as important sources of human exposure to PAHs, highlighting the oil and fat group. 3,4,11,[14][15][16][17][18] The presence of polycyclic aromatic hydrocarbons in vegetable oils may be attributed to (i) atmospheric contamination of plant material, (ii) direct drying of the plant material with combustion smoke before extraction, (iii) contamination through the solvent extraction and (iv) uptake by the oil plants from contaminated soils. 2,14 During the refining processes, the concentrations of these contaminants can be drastically reduced.…”

“…Entre os processamentos de alimentos em que ocorrem produção de HAP incluem-se defumação, secagem direta com madeira ou carvão (churrasco e parrillada, por exemplo) e torrefação 50,53 . Durante o processo de assar a carne na brasa, a gordura é pirolisada pela ação da chama direta na peça, assim como pelo calor do carvão, gerando os HAP carcinogênicos.…”

“…A quantidade de cafeína no café fervido com a água é até 30% maior do que no café coado diretamente. Portanto, a fervura facilita a passagem de hidrocarbonetos para a bebida pela maior liberação de cafeína e pela formação do complexo benzo(a)pireno-cafeína 53 .…”
