Caracterização físico-química do caroço e da fibra do açaí (Euterpe oleracea mart.) via métodos clássicos e instrumentais

Matheus Maciel Santos,
Fernanda Souza Pasolini,
Ana Paula Oliveira Costa

Abstract: O açaí, fruto do açaizeiro (Euterpe oleracea Mart.), tem grande importância no setor agroindustrial brasileiro, sendo largamente consumido no país. A cultura do açaí gera como resíduos o caroço e a fibra, que geralmente são descartados sem tratamentos prévios. Existem poucos dados relativos à caracterização físico-química desses resíduos e possibilidades de reutilização ainda não foram definidas. Nesse contexto, este trabalho objetivou estudar a caracterização físico-química e térmica do caroço, da fibra e dos… Show more

“…In order to understand how the process changes with increasing temperature, it is advisable to know the chemical composition of açaí seeds. According to the academic literature, dried açaí seeds are made up of 18.6% cellulose, 58.1% hemicellulose and 25.1% lignin [42,43]. This composition is important because it governs how decomposition of the material should occur with respect to process temperature.…”

“…Since açaí seeds are mainly composed of cellulose and hemicellulose, these biopolymers are the first to be degraded, and we observed aqueous phase production as early as 150 • C. As the temperature increases, lignin is degraded, producing organic bio-oil. Thermogravimetry analyses of açaí seeds show that decomposition due to celluloses, hemicelluloses, and the initial part of lignin occurs between 180 and 370 • C [42]. Indeed, at lower temperatures, an initial small amount of bio-oil is formed along with a large quantity of aqueous phase.…”
