Title A name given to the resource Microfibers for juice analysis by solid-phase microextraction Microfibras para análises de sucos por microextração em fase sólida Creator An entity primarily responsible for making the resource Renata Borchetta Fernandes Fonseca, Lucia Maria Jaeger de Carvalho, Carolina Netto Rangel, Humberto Ribeiro Bizzo Description An account of the resource In view of the interest in analyzing volatile compounds by SPME, the following five microfibers were tested, polydimethylsiloxane; polyacrylate; polydimethylsiloxane/divinylbenzene; carboxen/polydimethylsiloxane, and carbowax/divinylbenzene, to select the one which presents the best performance for the adsorption of the volatile compounds present in the headspace of acid lime juice samples. Sample stabilization time variations (30 and 60 minutes) were assessed as well the addition of NaCl to the samples. It was verified that the chromatogram with the most adsorbed volatile compounds was obtained with PDMS/DVB microfiber at 30 minutes and the addition of 0.2 g NaCl.Diante do interesse de analisar substâncias voláteis pelo método de Microextração em Fase Sólida (MEFS), foram testadas cinco microfibras de polidimetilsiloxano - PDMS; poliacrilato - PA; polidimetilsiloxano/divinilbenzeno - PDMS/DVB; carboxen/polidimetilsiloxano CAR/PMDS e carbowax/divinilbenzeno - CW/DVB no presente trabalho, a fim de selecionar a microfibra de melhor desempenho para a adsorção das substâncias voláteis presentes no headspace das amostras de suco de lima ácida (Citrus latifolia, Tanaka) cv. Tahiti, obtida por cultivo biodinâmico. As microfibras selecionadas foram PDMS/DVB e PDMS, por apresentarem cromatogramas com maior número de componentes, onde não houve adição prévia de NaCl. A seguir, as microfibras de PDMS/DVB e PDMS foram avaliadas variando-se o tempo de estabilização da amostra (30 e 60 minutos), bem como a adição de NaCl. Verificou-se que o cromatograma com mais substâncias voláteis adsorvidas foi obtido com o uso da microfibra de PDMS/DVB, no tempo de 30 minutos e com a adição de 0,2 g de NaCl.
