Glycerolysis of Buriti Oil ( Mauritia flexuosa) by Magnesium Oxide and Immobilized Lipase Catalysts: Reaction Yield and Carotenoids Degradation
Abstract Buriti ( Mauritia flexuosa ) is a palm tree widely distributed in South America. The oil extracted from its fruit is an added value product for its high carotenoids content. The aim of this work was to evaluate the alkaline (magnesium oxide—MgO) and enzymatic (lipase B from Candida antarcti...
