PROCESSO PARA A RECUPERACAO INDUSTRIAL DE ACIDOS OLEANOLICO E MASLINICO CONTIDOS NOS SUBPRODUTOS DA MOAGEM DA AZEITONA

摘要

Process for the recovery of oleanolic and maslinic acids contained in the subproducts resulting from the milling and processing of olives or parts thereof, either proceeding from three-phase or two-phase presses. This process enables to obtain, by separation and with purities higher than 80%, of both acids with yields comprised between 0.2 and 1.5%, as a function of the product and prime material processed. Fundamentally, it comprises selective extractions and fractionation of resulting mixtures with the use of solvents.
