Artigo Determination of tocopherols and physicochemical properties of faveleira (Cnidoscolus quercifolius) seed oil extracted using different methods(Food Science and Technology, 2019) Ribeiro, Karla Danielly da Silva; Silva, Denise Maria de Lima e; Dantas, Mariana Mesquita; Ribeiro, Penha Patrícia Cabral; Dimenstein, Roberto; Damasceno, Karla Suzanne Florentino da Silva Chaves; 0000-0002-2251-5967This study aims to evaluate the physicochemical properties and tocopherol content in faveleira seed oil extracted using three methods (Bligh-Dyer, Soxhlet extractor, and cold-pressing). Each of the methods generated different yield percentages, with cold-pressing producing the least amount of oil. However, the cold-pressing method produced better quality oil with more desirable properties, including low acidity (1.56 ± 0.01% oleic acid) and low peroxide value (0.45 ± 0.09 mEq/1000 g). Cold-pressing resulted in higher quantities of tocopherols: 0.59 ± 0.12 mg/100 g of alpha-tocopherol and 20.97 ± 1.15 mg/100 g of beta + gamma-tocopherol. Faveleira seed oil, when extracted by cold-pressing, maintains better physicochemical quality, with the highest beta + gamma-tocopherol content.Artigo Determination of tocopherols and physicochemical properties of faveleira (Cnidoscolus quercifolius) seed oil extracted using different methods(Food Science and Technology, 2019-06) Damasceno, Karla Suzanne Florentino da Silva Chaves; Ribeiro, Penha Patrícia Cabral; Silva, Denise Maria de Lima e; Dantas, Mariana Mesquita; Ribeiro, Karla Danielly da Silva; Dimeinstein, RobertoThis study aims to evaluate the physicochemical properties and tocopherol content in faveleira seed oil extracted using three methods (Bligh-Dyer, Soxhlet extractor, and cold-pressing).
