Artigo Chemical composition of faveleira (Cnidoscolus phyllacanthus) seeds collected in different seasons(Revista Ceres, 2018-06) Damasceno, Karla Suzanne Florentino da Silva Chaves; Medeiros, Jovilma Maria Soares de; Ribeiro, Penha Patrícia Cabral; Freitas, Erika Paula Silva; Santos, Jéssica Anarellis Barbosa dosCnidoscolus phyllacanthus, popularly known as favela or faveleira, is a species of the caatinga vegetation highly resistant to drought, with high nutritional content, and having several uses. The objective of this work was to evaluate the influence of different seasons on the chemical composition of faveleira seeds in the region of Seridó/RN. The seeds collected in different seasons were separated into 3 lots (lot 1 - rainy season; lot 2 - initial dry season; lot 3 - prolonged dry season), ground, and analyzed for moisture, ash, lipids, protein, and carbohydrates. The chemical analysis the seeds showed predominance of lipids and proteins. The results showed that moisture was significant different (p < 0.05) between all the lots; the ash content in lot 1 was significantly (p < 0.05) lower (4.67 ± 0.18) than lot 3 (4.96 ± 0.08); and protein content was highest in lot 3 (30.42 ± 1.63) and significantly (p < 0.05) different from the others. There was a significant difference (p < 0.05) for lipids between the lots, with lot 2 showing the lowest content (21.57 ± 0.37). Significant difference (p < 0.05) was also found for carbohydrates between the lots, with lot 1 (14.37 ± 1.83) having the lowest content and lot 2 (39.17 ± 0.52) the highest content. The differences observed between the lots are attributed to the harvest of the seeds in different seasonal periods. The results show that the seasonal period influences the nutritional value of faveleira seeds, and that better forms of use need to be identified according to the period of harvestingArtigo Cnidoscolus quercifolius: nutritional value, bioactive activity and potential application of seed and its derivatives in human nutrition(Trends in Food Science & Technology, 2020-11) Damasceno, Karla Suzanne Florentino da Silva Chaves; Ribeiro, Penha Patrícia Cabral; Medeiros, Jovilma Maria Soares deBackground: Faveleira (Cnidoscolus quercifolius) is a plant native to Caatinga and resistant to drought periods. The seed of this plant is an oilseed and its nutritional composition may vary according to the presence or not of thorns and depending on the period in which it was collected. Different derivatives can be obtained from the seed: oil, press cake, flour, almond, and protein isolate. Scope and approach: This article aims to collect information about the faveleira, pointing out the gaps that have not been researched and underlining the nutritional value, bioactive activity and potential use of the seeds and their derivatives in human food. Key findings and conclusions: The faveleira seed can be used in several ways. Its derivatives have the potential to be used in human food and have bioactive compounds in their composition. Among these derivatives, oil is the most studied to date and the press cake stands out for its high antioxidant activity. In order to promote the use of faveleira seed and its derivatives in human food, further studies about other bioactive activities of oil, description and use of the various derivatives in food products, isolation of bioactive compounds and the viability of processing these derivatives at the industrial level are needed
