Resumo: | Oats have high production potential, mainly from the southern region of Brazil. They are highlighted due to their nutritional characteristics with various benefits to human health. The use of products containing oat fiber has attracted great interest because of the functionality of these foods in order to alleviate and prevent disease such as hypercholesterolemia, diabetes and cardiovascular disease. The aim of this study was to determine the chemical composition and sensory changes in appearance, texture and tastes of oats in different forms of processing. For the chemical composition, the samples were grain oat, de-hulled oats, hulled oats, toasted oats, oat flakes, thin oat flakes, oat bran and oatmeal. For sensory analysis, samples of oat flakes, thin oat flakes, oat bran and oatmeal were used. The different forms of oats processing were analyzed for dry matter, ash, proteins, lipids, total dietary fiber, insoluble fiber, soluble fiber, no fiber carbohydrates and minerals (calcium, phosphorus, magnesium, potassium, zinc, iron, manganese and copper). Sensory analysis was performed through affective tests of acceptability with a 7-point scale, preference ranking test and purchase intent, with a 5-point scale. The studied samples showed differences in chemical composition. These differences are related to grain morphology, including the hull. It was observed that the oats grain even being higher in nutrients compared to other cereals, shows differences in nutrient content between its different processes. This difference occurs mainly for the oat bran, which has a higher concentration of fibers, proteins, lipids and minerals. The acceptability averaged 5.11, 5.45 and 5.37, with a maximum of seven grade, for appearance attributes, texture and flavor, respectively. The flakes and thin flakes indicated a greater buying intent and preference, followed by oat bran, among the judges. Thus, the inclusion or addition of oat products in human diet, especially the meal, should be valued due to its higher nutritional value. This requires further studies on the topic, considering the current investment in nutritional quality. |

Apresenta destaque devido as suas características nutricionais com vários benefícios à saúde humana. O uso de produtos contendo fibras de aveia tem despertado grande interesse devido à funcionalidade desses alimentos, no sentido de amenizar e prevenir doença como hipercolesterolemia, diabetes e doenças cardiovasculares. O objetivo desse trabalho foi determinar a composição química, assim como avaliar sensorialmente a aparência, textura e sabor de amostras de grãos de aveia em diferentes formas de processamento. Para a composição química foram utilizadas amostras de grãos de aveia com casca, grãos de aveia descascada, grãos de aveia descascada tostada, aveia em flocos, aveia em flocos finos, farelo de aveia e farinha de aveia. Para a análise sensorial utilizou-se amostras de aveia em flocos, aveia em flocos finos, farelo de aveia e farinha de aveia. As diferentes formas de processamento da aveia foram analisadas quanto aos teores de matéria seca, cinzas, proteínas, lipídeos, fibra alimentar total, fibra insolúvel, fibra solúvel, carboidratos não-fibrosos e minerais (cálcio, fósforo, magnésio, potássio, zinco, ferro, manganês e cobre). A análise sensorial foi realizada a partir de testes afetivos de aceitabilidade, com escala hedônica de 7 pontos, teste de ordenação (preferência) e intenção de compra, com escala de 5 pontos. As amostras estudadas apresentaram diferenças na composição química. Estas diferenças estão relacionadas com a morfologia do grão, incluindo a casca. Observou-se que o grão de aveia mesmo sendo superior em nutrientes em relação a outros cereais, apresenta diferenças de teores dos nutrientes entre os seus diferentes processos. Essa diferença ocorre principalmente para o farelo de aveia, o qual possui maior concentração de fibras, proteínas, lipídeos e minerais. Os flocos e flocos finos indicaram maior intenção de compra e maior preferência, seguido do farelo de aveia, entre os julgadores. Dessa forma, a inclusão dos produtos de aveia na dieta humana, em especial o farelo por apresentar maior valor nutricional, deve ser valorizada. Para tanto é necessário mais estudos sobre o tema, considerando o atual investimento em qualidade nutricional.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Ciência e Tecnologia dos AlimentosUFSMBRCiência e Tecnologia dos AlimentosAveiaAvaliação químicaProcessamentoAnálise sensorialOatsChemical evaluationProcessingSensory analysisCNPQ::CIENCIAS AGRARIAS::CIENCIA E TECNOLOGIA DE ALIMENTOSAvaliação química e sensorial do grão da aveia em diferentes formas de processamentoChemical and sensory evaluation of oats in different forms of processinginfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisNörnberg, José Laertehttp://lattes.cnpq.br/1252443045127710Hecktheuer, Luisa Helena Rycheckihttp://lattes.cnpq.br/7926116604048817Rech, Virginia Cielohttp://lattes.cnpq.br/0969715025616160http://lattes.cnpq.br/3134675854353465Dal Molin, Viviane Terezinha Sebalhos5007000000064005003005003007ac0e6d5-9893-4fed-84ef-69171f1cb67b508c92e6-1160-4b19-8a61-2b13f919de672e52a810-fba7-4d12-86c6-230ed32195a0e7f2eaea-4828-4aae-8027-1a9a1b8af03ainfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDAL MOLIN, VIVIANE TEREZINHA SEBALHOS.pdfapplication/pdf779866http://repositorio.ufsm.br/bitstream/1/5697/1/DAL%20MOLIN%2c%20VIVIANE%20TEREZINHA%20SEBALHOS.pdf9a11c90d27f54e27b721d333555d3fb6MD51TEXTDAL MOLIN, VIVIANE TEREZINHA SEBALHOS.pdf.txtDAL MOLIN, VIVIANE TEREZINHA SEBALHOS.pdf.txtExtracted texttext/plain143151http://repositorio.ufsm.br/bitstream/1/5697/2/DAL%20MOLIN%2c%20VIVIANE%20TEREZINHA%20SEBALHOS.pdf.txtcc4141193ff839a38e34c8691968f2caMD52THUMBNAILDAL MOLIN, VIVIANE TEREZINHA SEBALHOS.pdf.jpgDAL MOLIN, VIVIANE TEREZINHA SEBALHOS.pdf.jpgIM Thumbnailimage/jpeg4776http://repositorio.ufsm.br/bitstream/1/5697/3/DAL%20MOLIN%2c%20VIVIANE%20TEREZINHA%20SEBALHOS.pdf.jpg31a34c78167222dc6165c1d8c3070428MD531/56972022-06-02 09:37:12.497oai:repositorio.ufsm.br:1/5697Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-06-02T12:37:12Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |

Oats have high production potential, mainly from the southern region of Brazil. They are highlighted due to their nutritional characteristics with various benefits to human health. The use of products containing oat fiber has attracted great interest because of the functionality of these foods in order to alleviate and prevent disease such as hypercholesterolemia, diabetes and cardiovascular disease. The aim of this study was to determine the chemical composition and sensory changes in appearance, texture and tastes of oats in different forms of processing. For the chemical composition, the samples were grain oat, de-hulled oats, hulled oats, toasted oats, oat flakes, thin oat flakes, oat bran and oatmeal. For sensory analysis, samples of oat flakes, thin oat flakes, oat bran and oatmeal were used. The different forms of oats processing were analyzed for dry matter, ash, proteins, lipids, total dietary fiber, insoluble fiber, soluble fiber, no fiber carbohydrates and minerals (calcium, phosphorus, magnesium, potassium, zinc, iron, manganese and copper). Sensory analysis was performed through affective tests of acceptability with a 7-point scale, preference ranking test and purchase intent, with a 5-point scale. The studied samples showed differences in chemical composition. These differences are related to grain morphology, including the hull. It was observed that the oats grain even being higher in nutrients compared to other cereals, shows differences in nutrient content between its different processes. This difference occurs mainly for the oat bran, which has a higher concentration of fibers, proteins, lipids and minerals. The acceptability averaged 5.11, 5.45 and 5.37, with a maximum of seven grade, for appearance attributes, texture and flavor, respectively. The flakes and thin flakes indicated a greater buying intent and preference, followed by oat bran, among the judges. Thus, the inclusion or addition of oat products in human diet, especially the meal, should be valued due to its higher nutritional value. This requires further studies on the topic, considering the current investment in nutritional quality. |
