Resumo: | Soybean and its derivatives have the desired properties for food either for humans or various animals because of its high protein content, which is associated to a good balance of amino acids. However, when the protein is hydrolyzed into smaller peptides, the nutritional value can increase further. A product with high nutritional value added but which does not present economic viability is not interesting for the industry. To analyze such viability, there are softwares that simulate and analyze a process plant. Thus, this study is two-fold: the mathematical modeling of the hydrolysis process and a preliminary analysis of economic viability. Concerning the modeling, two models were fitted: one that relates time with the degree of enzymatic hydrolysis of proteins of concentrated soybean meal and another that relates the degree of hydrolysis with the molecular weight distribution of the pseudocomponents. The analysis of economic viability was conducted using software SuperPro Designer. For this purpose, a degree of hydrolysis and its molecular weight distribution was chosen, and then, an industrial plant was modeled and simulated in a preliminary project level. For the kinetic model, hydrolysis was conducted in laboratorial scale, using a pHstat and an enzyme called Novo-Pro D. The product was analyzed by liquid chromatography. The data were analyzed and the ones obtained in the best conditions were used to fit the model. The best conditions were 55oC, pH 9, 90% humidity, 0,5% m(enz/sub). The kinetic fitting was well described by the Michaelis-Menten with competitive inhibition and neural network described with high fidelity the relation between the concentration of the pseudocomponents and the degree of hydrolysis. Regarding the analysis of the preliminary project of an industrial plant for the production of hydrolyzed protein of concentrated soybean meal, the plant was economic viable, but the project is in a very preliminary stage, due to a lot of unknown data so they were estimated increasing the uncertainty of results. |

Porém, quando a proteína é hidrolisada em peptídeos menores, seu valor nutricional pode aumentar ainda mais. Um produto com grande valor nutricional agregado, mas que não é viável economicamente, não é interessante para a indústria. Para analisar tal viabilidade, existem softwares que simulam e analisam economicamente a planta de um processo. Assim, este trabalho teve como objetivo, primeiramente, desenvolver dois modelos: um que relacionasse o tempo com o grau de hidrólise obtido na reação de hidrólise enzimática das proteínas do farelo de soja concentrado pela enzima Novo-Pro D e outro que relacionasse esse grau de hidrólise com seu perfil peptídico gerado. Posteriormente, escolhido um grau de hidrólise e seu perfil peptídico, modelar e simular, nessas condições, uma possível planta industrial, na fase de projeto preliminar, para a hidrólise das proteínas do farelo de soja concentrado. Por fim, a viabilidade econômica dessa planta foi analisada, utilizando-se para isto o software SuperPro Designer. Para o ajuste dos modelos matemáticos, foram feitos testes em escala laboratorial, utilizando um pHstato, equipamento que faz medidas do grau de hidrólise e um cromatógrafo líquido, para a análise do perfil peptídico formado após a hidrólise. Os dados obtidos pelos experimentos foram analisados e as condições de hidrólise que apresentaram melhores benefícios foram utilizadas para se fazer o ajuste dos modelos. Os resultados obtidos, em relação às melhores condições, foram 90% umidade, temperatura de 55 oC, pH 9 e relação enzima/substrato de 0,5% (m/m). O ajuste cinético foi muito bem descrito pelo modelo de Michaelis-Menten com inibição competitiva, assim como a rede neural descreveu de maneira satisfatória a relação entre a concentração dos pseudocomponentes em um dado grau de hidrólise. Em relação à análise do projeto preliminar de uma planta para a produção de hidrolisados protéicos de farelo de soja concentrado, a planta se mostrou viável economicamente, mas o resultado guarda muitas incertezas, devido ao projeto se encontrar em uma fase muito preliminar e devido à falta de muitos dados de processo, que foram estimados.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)porUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Engenharia Química - PPGEQUFSCarEngenharia químicaProcessos químicosBioprocessosEnzimasProteinasModelagem matemáticaENGENHARIAS::ENGENHARIA QUIMICA::PROCESSOS INDUSTRIAIS DE ENGENHARIA QUIMICAInovações na produção de hidrolisados de soja: modelagem e análise econômica de processoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisOnline60060096eca1d7-07f8-4bbb-8b1f-ee5951a6def3info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissCP.pdfDissCP.pdfapplication/pdf3881043https://repositorio.ufscar.br/bitstream/ufscar/8460/1/DissCP.pdf0d91cb854f8bf16d1bcbdd2e83f37338MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/8460/2/license.txtae0398b6f8b235e40ad82cba6c50031dMD52TEXTDissCP.pdf.txtDissCP.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/8460/3/DissCP.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD53THUMBNAILDissCP.pdf.jpgDissCP.pdf.jpgIM Thumbnailimage/jpeg5587https://repositorio.ufscar.br/bitstream/ufscar/8460/4/DissCP.pdf.jpgeccd8e1177347a02fab0ef34473d2825MD54ufscar/84602023-09-18 18:31:06.333oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:06Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

Soybean and its derivatives have the desired properties for food either for humans or various animals because of its high protein content, which is associated to a good balance of amino acids. However, when the protein is hydrolyzed into smaller peptides, the nutritional value can increase further. A product with high nutritional value added but which does not present economic viability is not interesting for the industry. To analyze such viability, there are softwares that simulate and analyze a process plant. Thus, this study is two-fold: the mathematical modeling of the hydrolysis process and a preliminary analysis of economic viability. Concerning the modeling, two models were fitted: one that relates time with the degree of enzymatic hydrolysis of proteins of concentrated soybean meal and another that relates the degree of hydrolysis with the molecular weight distribution of the pseudocomponents. The analysis of economic viability was conducted using software SuperPro Designer. For this purpose, a degree of hydrolysis and its molecular weight distribution was chosen, and then, an industrial plant was modeled and simulated in a preliminary project level. For the kinetic model, hydrolysis was conducted in laboratorial scale, using a pHstat and an enzyme called Novo-Pro D. The product was analyzed by liquid chromatography. The data were analyzed and the ones obtained in the best conditions were used to fit the model. The best conditions were 55oC, pH 9, 90% humidity, 0,5% m(enz/sub). The kinetic fitting was well described by the Michaelis-Menten with competitive inhibition and neural network described with high fidelity the relation between the concentration of the pseudocomponents and the degree of hydrolysis. Regarding the analysis of the preliminary project of an industrial plant for the production of hydrolyzed protein of concentrated soybean meal, the plant was economic viable, but the project is in a very preliminary stage, due to a lot of unknown data so they were estimated increasing the uncertainty of results. |
