DIETARY FIBRE CONTENT, PHENOLIC COMPOUNDS AND ANTIOXIDANT ACTIVITY IN SOURSOPS (Annona muricata L.)

Abstract

-healthy eating is associated with the consumption of fruits, which are notable for their beneficial effects on human health. The aim of this study was to evaluate the proximate composition, composition of fibers and components with antioxidant activity in soursops varieties Crioula, Lisa and morada of physiological maturity (Pm) and mature (m). The protein, lipid and moisture contents did not differ between soursop varieties, but the ash contents were higher in the morada-Pm (0.56%±0.03) and the Morada-M (0.82%±0.10) varieties. The Crioula-M variety showed higher levels of total dietary fibre (5.76%±0.12). The Lisa-M variety showed higher levels of insoluble dietary fibre (4.46%±0.00). The Lisa-M variety also showed a higher level of phenolic compounds (284.25 mg gallic acid/100 g of soursop pulp), differing significantly (p <0.05) from the Crioula-PM soursop (154.40 mg of gallic acid/100 g of soursop pulp). under the DPPh• system, the soursops that showed highest antioxidant activity were the Crioula-m (eC50 of 156.40 g.g DPPh ), which differed significantly from the morada soursops. The results suggest that the consumption of soursops is useful for increasing concentrations of bioactive compounds and dietary fibre. Index terms: tropical fruit, dietary fibre, phenolics, antioxidant activity. CONTEÚDO DE FIBRA ALIMENTAR, COMPOSTOS FENOLICOS E ATIVIDADE ANTIOXIDANTE EM GRAVIOLA (Annona muricata L.)RESUMO -Alimentação saudável e equilibrada está associada ao consumo de frutas, visto que, frequentemente, apresentam elementos com efeitos benéficos à saúde humana. O objetivo deste estudo foi avaliar a composição centesimal, composição de fibras e componentes com atividade antioxidante em soursops variedades Crioula, Lisa e Morada em estádio de maturação fisiológica (PM) e madura (M).. Os conteúdos de proteínas, lipídios e umidade não diferiram entre as variedades de graviola, mas os teores de cinza foram maiores nas variedades morada-Pm (0,56% ± 0,03) e morada-m (0,82% ± 0,10). A variedade Crioula-m apresentou níveis mais altos de fibra dietética total (5,76% ± 0,12). A variedade Lisa-M apresentou níveis mais elevados de fibra alimentar insolúvel (4,46% ± 0,00) e também maior nível de compostos fenólicos (284,25 mg ácido gálico/100 g polpa de graviola), diferindo significativamente (p <0,05) da graviola Crioula-PM (154,40 mg ácido gálico/100 g polpa de graviola

EVALUATION OF EMERGING METHODS ON THE POLYPHENOL CONTENT, ANTIOXIDANT CAPACITY AND QUALITATIVE PRESENCE OF ACETOGENINS IN SOURSOP PULP (Annona muricata L.)

“…Formosum leaves by ultrasound than conventional method by heating. The level of EPPs in the methanol extract of soursop pulp found in this study was almost two times higher than reported by other authors in soursop pulp, who have reported values from 1.86 g GAE 100 g -1 DM (MORENO-HERNÁNDEZ et al, 2014;SIQUEIRA et al, 2015). The values of antioxidant capacity determined by DPPH…”

“…The more soursop puree, the greater the total dietary fiber value (Table 1). According to Michaelsen et al (2009) and Siqueira et al (2015), the dietary fiber content on soursop puree is of 3.72-5.76%, while that of horn plantain which is 2.3%. The ratio of 1:3 produces the highest total dietary fiber of 5.82±0.08%.…”

“…Em termos nutricionais, a graviola apresenta conteúdo médio de umidade de 80%, seguido de carboidratos totais de 4,7%, fibras totais com relevância para as fibras insolúveis de 3,6%. O teor médio de compostos fenólicos totais é de 244 mg de ácido gálico por grama de fruta (SIQUEIRA et al, 2015). Também é uma boa fonte de vitaminas do complexo B, sendo de extrema importância para o metabolismo de gorduras, carboidratos e proteínas, adicionando ao cardápio vitaminas e minerais, além de ser ótimo para a saúde (JUNQUEIRA; JUNQUEIRA, 2014).…”
