Resumo: | The purpose of the present investigation was to characterize the pitanga seeds on centesimal composition, and also to evaluate its antioxidant potential and fatty acid profile. For obtaining the extract, the dehydrated and ground seeds were treated with ethyl alcohol for 30 minutes, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation at room temperature. Afterwards, the mixture was filtered and the supernatant was placed into a rotoevaporator at 40ºC for determining the extract’s dry matter yield, by direct weighing. According to the results, the seeds of cherry showed high amounts of carbohydrates, and offer relevant content and antioxidant activity of phenolic compounds. In the seed oil, cherry high lighted a higher percentage of unsatured fatty acids, oleic being the main component. |

Para a obtenção do extrato, as sementes desidratadas e trituradas foram extraídas com álcool etílico por 30 minutos, na proporção de 1:3 de sementes:álcool etílico, sob agitação contínua à temperatura ambiente. Em seguida, a mistura foi filtrada e o sobrenadante submetido ao rotoevaporador a 40ºC com vistas a determinar, por pesagem direta, o rendimento em matéria seca do extrato. De acordo com os resultados obtidos, as sementes de pitanga demonstraram elevado teor de carboidratos totais, além de apresentarem relevante atividade antioxidante e teor de compostos fenólicos totais. No óleo das sementes de pitanga destacou-se maior porcentagem de ácidos graxos insaturados, sendo o oleico o principal componente.Universidade Estadual Paulista Júlio de Mesquita Filho, Departamento de Engenharia e Tecnologia de Alimentos, Instituto de Biociências Letras e Ciências Exatas de São José do Rio Preto, São José do Rio Preto, Rua Cristóvão Colombo, 2265 - Depto. de Engenharia e Tecnologia de Alimentos, Jardim Nazareth, CEP 15054000, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho, Departamento de Engenharia e Tecnologia de Alimentos, Instituto de Biociências Letras e Ciências Exatas de São José do Rio Preto, São José do Rio Preto, Rua Cristóvão Colombo, 2265 - Depto. de Engenharia e Tecnologia de Alimentos, Jardim Nazareth, CEP 15054000, SP, BrasilUniversidade Estadual Paulista (Unesp)Universidade de São Paulo (USP)Luzia, Débora Maria Moreno [UNESP]Bertanha, Bruna JorgeJorge, Neuza [UNESP]2015-04-27T11:55:31Z2015-04-27T11:55:31Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article175-180application/pdfhttp://revistas.bvs-vet.org.br/rialutz/article/view/6358Revista do Instituto Adolfo Lutz, v. 69, n. 2, p. 175-180, 2010.0073-9855http://hdl.handle.net/11449/122267ISSN0073-9855-2010-69-02-175-180.pdf660594862023010481362588352324594668535194933989Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporRevista do Instituto Adolfo Lutzinfo:eu-repo/semantics/openAccess2023-10-21T06:12:23Zoai:repositorio.unesp.br:11449/122267Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T15:33:51.426672Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
