Resumo: | The sweet potato (Ipomoea potatoes) is one of the most produced and consumed foods worldwide, being of easy cultivation and high nutritional value. Easily adapted, this tuber is rich in carbohydrates, thus possessing a high energy value. In addition to carbohydrates, it is a food rich in minerals (such as iron, calcium), vitamin A and B vitamins, being a good food for the immune system. The low shelf life and the low exploitation of agroindustrial potential are factors that influence the search for adding value to this product. Sweet potato flour maintains the nutritional value and can be used to enrich foods such as breads, biscuits, mass in general. The best known method for the production of flour is the drying of sweet potatoes in natura followed by grinding, however the study of simpler and economical dehydration methods are sought. Foam drying is a relatively simpler and more cost-effective method of increasing the contact surface between the mixture and the hot air, and it has advantages of being made in a shorter time and at a lower temperature when compared to Other drying methods. The present study consisted in analyzing the foam-mat drying in an experimental design 3² + 2, with the addition of Emustab® (1%, 2% and 3%) and temperature (70°C, 80°C and 90°C) as independent variables. Production yields were greater than 90% and as reconstituted flours retained as physical-chemical properties of the material prior to treatment. Moisture, water activity and hygroscopicity indicate good storage conditions. The increase in the addition of the blowing agent and the temperature had effects on the drying rates and on the effective diffusion coefficients, obtaining the fit of the Fick model to the experimental data of the drying no descending rate period. The Page model presented a good fit to the experimental data of the moisture ratio as a function of time, for all conditions studied. Key-words: Sweet potato, Ipomoea potatoes, drying, foam layer, flour. |

Key-words: Sweet potato, Ipomoea potatoes, drying, foam layer, flour.A batata-doce (Ipomoea batatas) é um dos alimentos mais produzidos e consumidos mundialmente, por ser de fácil cultivo e alto valor nutricional. De fácil adaptação, esse tubérculo é rico em carboidratos, possuindo assim um alto valor energético. Além de carboidratos, é um alimento rico em minerais (como ferro e cálcio), vitamina A e vitaminas do complexo B, sendo um bom alimento para o sistema imunológico (SEBBEN, 2015). A baixa vida de prateleira e o baixo aproveitamento do potencial agroindustrial são fatores que influenciam a busca por formas de agregar valor a esse produto. A farinha de batata-doce mantém o valor nutricional, além de poder ser utilizada no enriquecimento de alimentos, como pães, biscoitos, massas em geral. O método mais conhecido para a produção da farinha é a secagem da batata-doce in natura seguida por moagem, entretanto o estudo de métodos de desidratação mais simples e econômicos são buscados. A secagem em camada de espuma é um método relativamente mais simples e econômico que consiste em aumentar a superfície de contato entre a mistura e o ar quente. Possui ainda como vantagem o fato do processo ocorrer em tempo mais curto e em uma menor temperatura se comparado a outros métodos de secagem. O presente estudo consistiu em analisar a secagem da espuma de batata doce com base em um delineamento experimental 3² com 2 repetições no ponto central, tendo como variáveis independentes, a concentração do emulsificante (1%, 2% e 3%) e a temperatura (70°C, 80°C e 90°C). Os rendimentos de produção foram superiores a 90% e as farinhas reconstituídas mantiveram as propriedades físico-químicas do material antes do tratamento. A umidade, atividade de água e higroscopicidade indicam boas condições de conservação. O aumento da adição do agente espumante e da temperatura apresentaram efeitos sobre as taxas de secagem e sobre os coeficientes de difusão efetivo, obtidos pelo ajuste do modelo de Fick aos dados experimentais da secagem no período de taxa decrescente. O modelo de Page apresentou um ótimo ajuste aos dados experimentais da razão de umidade em função do tempo, para todas as condições estudadas.Universidade Federal do Rio Grande do NorteUFRNBrasilEngenharia QuímicaBatata-doceIpomoea batatassecagemcamada de espumafarinhaSweet potatoIpomoea potatoesdryingfoam layerflourEngenharias.Obtenção da farinha de batata-doce (Ipomoea Batatas) pelo processo Foam Matinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTObtencaodafarinha_Monografia.txtExtracted texttext/plain72095https://repositorio.ufrn.br/bitstream/123456789/38788/1/Obtencaodafarinha_Monografia.txt36e4ce7fa8546c6304fde8d2ea490cd6MD51LICENSElicense.txttext/plain756https://repositorio.ufrn.br/bitstream/123456789/38788/2/license.txta80a9cda2756d355b388cc443c3d8a43MD52ORIGINALObtencaodafarinha_MonografiaMonografiaapplication/octet-stream1073201https://repositorio.ufrn.br/bitstream/123456789/38788/3/Obtencaodafarinha_Monografia8f3bec756dc53f9e53f2dfdb37647ed3MD53CC-LICENSElicense_urlapplication/octet-stream43https://repositorio.ufrn.br/bitstream/123456789/38788/4/license_url321f3992dd3875151d8801b773ab32edMD54license_textapplication/octet-stream0https://repositorio.ufrn.br/bitstream/123456789/38788/5/license_textd41d8cd98f00b204e9800998ecf8427eMD55license_rdfapplication/octet-stream0https://repositorio.ufrn.br/bitstream/123456789/38788/6/license_rdfd41d8cd98f00b204e9800998ecf8427eMD56123456789/387882021-09-27 09:21:16.814oai:https://repositorio.ufrn.br:123456789/38788PGNlbnRlcj48c3Ryb25nPlVOSVZFUlNJREFERSBGRURFUkFMIERPIFJJTyBHUkFOREUgRE8gTk9SVEU8L3N0cm9uZz48L2NlbnRlcj4KPGNlbnRlcj48c3Ryb25nPkJJQkxJT1RFQ0EgRElHSVRBTCBERSBNT05PR1JBRklBUzwvc3Ryb25nPjwvY2VudGVyPgoKPGNlbnRlcj5UZXJtbyBkZSBBdXRvcml6YcOnw6NvIHBhcmEgZGlzcG9uaWJpbGl6YcOnw6NvIGRlIE1vbm9ncmFmaWFzIGRlIEdyYWR1YcOnw6NvIGUgRXNwZWNpYWxpemHDp8OjbyBuYSBCaWJsaW90ZWNhIERpZ2l0YWwgZGUgTW9ub2dyYWZpYXMgKEJETSk8L2NlbnRlcj4KCk5hIHF1YWxpZGFkZSBkZSB0aXR1bGFyIGRvcyBkaXJlaXRvcyBkZSBhdXRvciBkYSBtb25vZ3JhZmlhLCBhdXRvcml6byBhIFVuaXZlcnNpZGFkZSBGZWRlcmFsIGRvIFJpbyBHcmFuZGUgZG8gTm9ydGUgKFVGUk4pIGEgZGlzcG9uaWJpbGl6YXIgYXRyYXbDqXMgZGEgQmlibGlvdGVjYSBEaWdpdGFsIGRlIE1vbm9ncmFmaWFzIGRhIFVGUk4sIHNlbSByZXNzYXJjaW1lbnRvIGRvcyBkaXJlaXRvcyBhdXRvcmFpcywgZGUgYWNvcmRvIGNvbSBhIExlaSBuwrAgOTYxMC85OCwgbyB0ZXh0byBpbnRlZ3JhbCBkYSBvYnJhIHN1Ym1ldGlkYSBwYXJhIGZpbnMgZGUgbGVpdHVyYSwgaW1wcmVzc8OjbyBlL291IGRvd25sb2FkLCBhIHTDrXR1bG8gZGUgZGl2dWxnYcOnw6NvIGRhIHByb2R1w6fDo28gY2llbnTDrWZpY2EgYnJhc2lsZWlyYSwgYSBwYXJ0aXIgZGEgZGF0YSBkZXN0YSBzdWJtaXNzw6NvLiAKRepositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2021-09-27T12:21:16Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
