Extração De Taninos De Farinha De Semente De Graviola Por Ultrassom

Abstract: Os taninos são compostos fenólicos, responsáveis pela adstringência de muitos frutos e produtos vegetais, devido à precipitação de glicoproteínas salivares, o que ocasiona a perda do poder lubrificante, sendo considerado antinutricional. Com isso, o objetivo desse estudo foi avaliar a extração de taninos totais da farinha de semente de graviola, utilizando banho ultrassônico com diferentes solventes. Os taninos foram extraídos, por meio de banho ultrassônico, por 30 minutos, a temperatura ambiente, utilizando … Show more

“…Tannins form complexes with proteins, making them insoluble and inactivating enzymes. They may also be responsible for other detrimental effects to the diet, such as undesirable colors foods caused by enzymatic browning reactions and decreased palatability caused by the astringency that they add food due to precipitation of salivary glycoproteins (Alves et al, 2019).…”
