ABSTRACT
The commercial activity of the grey mullet (known as Tainha: TAI) and Tambaqui (TAM) generates tons of waste that can be turned into valuable resources. Therefore, this work aimed to chemically characterize and quantify the fatty acids profiles of the two fishes. GCMS quantification was performed by using calibration curves built from a standard that contains 19 FAME. The analysis revealed that visceral wastes from both fishes contain 16 fatty acids (FA) consisting of saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA). However, their compositions were different as FA side chains in TAI and TAM contain 12 to 20 and 13 to 22 carbon atoms, respectively. Also, the SFA amount in TAI was greater than in TAM. On the other hand, TAM is richer in MUFA and PUFA compared to TAI. Both have similar chemical compositions of ω-3 and ω-6 in PUFA and ω-5, ω-7, and ω-9 in MUFA.
ABSTRACT
O presente trabalho analisou a importância do pescado como alimento no contexto da segurança alimentar, ressaltando sua participação como via de transmissão do parasita Ascocotyle (Phagicola) longa para os seres humanos, com destaque para a descrição da biologia da tainha (Mugil liza), do trematódeo digenético Ascocotyle (Phagicola) longa e da pesquisa da presença de metacercárias em amostras de tainha comercializada no maior mercado atacadista de pescado da América Latina, a Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP). No período de abril de 2009 a maio de 2010, foram examinadas 92 amostras e todas estavam infestadas por metacercárias de Ascocotyle (Phagicola) longa. Concluí-se que para o consumo da tainha torna-se obrigatória a cocção total, sendo desaconselhada a preparação de pratos à base de peixes crus ou mal cozidos.
This study aimed to analyze the importance of fish as food in the context of food security, highlighting their participation as a route of transmission of the parasite Ascocotyle (Phagicola) long for humans, especially the description of the biology of gray mullet (Mugil liza) of digenetic trematode Ascocotyle (Phagicola) longa and research metacercariae of the parasite in samples of mullet from the biggest wholesale fish market in Latin America, the São Paulo General Warehousing and Centers Company (CEAGESP). Ninety two samples were collected from May 2009 to April 2010 and all of them were infested with metacercariae of Ascocotyle (Phagicola) longa. It is concluded that for the consumption of mullet it becomes mandatory full cooking, being discouraged preparing dishes based on raw or undercooked fish.
