Item Use of natural yogurt, pineapple juice, and beer wort as starter cultures in sourdough combined with white and whole wheat flours to improve the technological characteristics of milk breads.(2023) Santos, Janaína Gomes dos; Ávila, Poliana Martins de; Gomes, Raphael Antônio Borges; Monteiro, Reginaldo de Souza; Vieira, Silvia Mendonça; Pereira, Patrícia Aparecida PimentaThe objective of this study was to investigate the combined effects of different types of wheat flour (whole or white) with natural yogurt, pineapple juice, and beer wort for sourdough production to improve the technological characteristics of milk breads. Seven milk breads were prepared with varying yeast fermentation and sourdough types (produced with different types of wheat flour and substrates). A physical analysis (oven jump, bread shape, crust thickness, expansion coefficient, and images of the slices), proximal composition examination (moisture, carbohydrates, proteins, lipids, and ash), and acceptability and purchase intent evaluation were then performed. The results showed that the factors under study influenced the technological characteristics of the milk breads, and that the sourdough consisting of whole wheat flour and yogurt was less acceptable. However, sourdough prepared using white wheat flour and beer wort was the most effective, being a promising alternative in the elaboration of milk breads.Item Evaluation of the effect of substrates and types of wheat flour on microbiological characteristics, pH values, levels of total phenolic compounds, antioxidant capacity and fermentative capacity of sourdough.(2022) Santos, Janaína Gomes dos; Ávila, Poliana Martins de; Schimitberger, Rodrigo; Cunha, Luciana Rodrigues da; Gomes, Raphael Antônio Borges; Vieira, Michele Cristina; Monteiro, Reginaldo de Souza; Vieira, Silvia Mendonça; Pereira, Patrícia Aparecida PimentaSourdough is a process that is expanding nowadays. However, the microorganisms present produce metabolites that can cause changes in the breads. Thus, the objective of this work was to evaluate the effects of substrates and types of wheat flour on microbiological characteristics, pH values, total phenolic compounds, antioxidant capacity and fermentative capacity of different types of sourdough, comparing them with dry yeast. In this way, six sourdough were elaborated, diversifying the type of wheat flour (whole or white) and the substrate (beer wort, pineapple juice or natural yogurt), being evaluated in the microbiological aspects (yeast count, bacteria under anaerobic conditions and under aerobic conditions), physicochemical (pH, phenolic compounds and antioxidant capacity (β-carotene/linoleic acid, ABTS and DPPH)) and fermentative capacity (only in sourdough). In view of the results obtained, it was observed that both white wheat flour and whole wheat flour, with the substrates yogurt, pineapple juice and brewer's wort, showed differences in microbiological characteristics, in pH values, in the content of compounds total phenolics, antioxidant capacity and fermentative capacity compared to dry yeast, with whole wheat flour, pineapple or beer wort providing microbial diversity, as well as lowering the pH. WY (white wheat flour and yogurt), WP (white wheat flour and pineapple) and IW (whole wheat flour and beer wort) sourdough were more resistant to temperatures (25 °C, 30 °C e 35 °C).Item Análise de características físicas e sensoriais de bolos de abacaxi com substituição e/ou redução de sacarose.(2021) Mendes, Elaine Cristina; Mota, Bruna Eugênia Ferreira; Vasconcelos, Christiane Mileib; Pereira, Patrícia Aparecida Pimenta; Cunha, Simone de Fátima Viana daA sacarose é um importante contribuinte para o valor calórico total de um alimento, além de ser um nutriente muito relevante para algumas patologias, como diabetes mellitus. Esse estudo objetivou reformular uma preparação de bolo de abacaxi, reduzindo e/ou substituindo o teor de açúcar. Uma receita de bolo de abacaxi foi escolhida, padronizada e receitas com modificações foram confeccionadas. Elaborou-se 8 formulações, sendo: B1-Padrão; B2-Padrão com redução de 50 % de açúcar cristal; B3-Açúcar mascavo; B4-Açúcar mascavo com redução de 50%; B5- Açúcar light; B6-Açúcar light com redução de 50%; B7- Edulcorante e B8- Edulcorante com redução de 50%. Posteriormente foram realizadas análises física e sensorial das preparações. Uma maior densidade específica da massa crua foi observada em B5 e uma menor densidade em B8. Em relação ao volume específico dos bolos, as maiores médias foram encontradas em B1, B7 e B8. As formulações B1, B2 e B6 obtiveram uma maior aceitação em relação aos atributos, doçura, consistência, aparência e impressão global. Com a redução em 50% ou substituição do açúcar pelo adoçante, como visto em B2 e B6, respectivamente, não houve alteração estatisticamente significativa nas características físicas delas, tampouco foi fator de rejeição. Dessa forma, possibilita-se o desenvolvimento de formulações de bolos de abacaxi, com redução e/ou substituição do açúcar sem perder suas propriedades sensoriais e físicas de volume, de forma a garantir sua aceitabilidade.Item Effect of calcium chloride and gelling agents on the physicochemical and sensory characteristics of sugar-free banana preserves.(2023) Dias, Ana Clara Costa; Barbosa, Lais Cristina dos Santos; Guia, Michael Douglas Machado; Silveira, Clara Gomes da; Barcelos, Juliana Carvalho; Santos, Izabela Silva dos; Cunha, Luciana Rodrigues da; Pereira, Patrícia Aparecida PimentaBanana preserve is produced by mixing the puree of the fruit with sucrose and organic acids. However, concerns about body esthetics or health reasons have encouraged the search for low-calorie products. Therefore, the objective of this study was to evaluate the effect of calcium chloride (CaCl2 ), carrageenan gum, and low methoxyl pectin (LM-pectin) on the physicochemical and sensory characteristics of sugar-free banana preserves. By using a central composite rotational design (CCRD) of 23 + 6 axial points + 4 central points, we obtained 18 formulations that were further tested. Lower CaCl2 concentrations (0.54% to 0.61%) resulted in preserves with lower pH and more vivid color. The increased concentration of LM-pectin (1.40% to 1.64%) resulted in formulations with a yellowish-red hue and with lower moisture, thus, reducing the flavor and purchase intention of the product. Higher concentrations of carrageenan gum (1.04% to 1.15%) decreased the perception of banana preserve aroma. Therefore, concentrations of CaCl2 ranging from 0.54% to 0.61%, carrageenan gum ranging from 0.74% to 0.89% and LM-pectin ranging from 1.40% to 1.64% resulted in sugar-free banana preserves with ideal sweetness and consistency and were, therefore, more acceptable.Item Food and behavior profile of children with autism spectrum disorder (ASD) in city of Ouro Preto/MG.(2023) Santos, Késia Regina Ferreira; Gomes, Bruna Letícia Oliveira; Vieira, Silvia Mendonça; Ribeiro, Marcelo Carlos; Pereira, Patrícia Aparecida PimentaAutism is a developmental disorder that affects communication, behavior, and social interaction. Autism symptoms may include delayed language development, difficulty making eye contact, repetitive movements or behaviors, and sensitivity to certain sensory stimuli. Therefore, the objective of this study was to evaluate the dietary and behavioral profile of children with Autism Spectrum Disorder (ASD) in city of Ouro Preto/MG. For this, the medical records of 11 children/young people assisted by the Association of Parents and Friends of the Exceptional (APAE) and the Psychosocial Care Center (CAPSij) in Ouro Preto/MG were evaluated. In addition, the responses obtained by parents and/or guardians about the dietary and behavioral profile of these individuals assisted by the institutions were evaluated using a questionnaire. The results were analyzed using word clouds and frequency analysis. In view of this, it is concluded that the dietary profile of children/young people with ASD is marked by food selectivity and that the main sensory aspect related to selectivity is texture, and that the foods most consumed by this group are industrialized foods, sugary foods and foods with low nutritional value. The least consumed are vegetables and fruits. In addition, the overload of mothers of children/young people with ASD was evident, being related to the great dependence of individuals on the mother.Item Rheological parameters of mixed Brazilian Cerrado fruits sugar-free preserves : the effect of body agents.(2023) Farias, Taísa Rezende Teixeira; Schiassi, Maria Cecília Evangelista Vasconcelos; Pereira, Patrícia Aparecida Pimenta; Souza, Vanessa Rios de; Lago, Amanda Maria Teixeira; Borges, Soraia Vilela; Queiroz, FabianaThe aim of this study was to evaluate the effect of the bodying agents (erythritol, sorbitol, xylitol, and polydextrose) and their mixtures on the preparation of mixed Brazilian Cerrado fruit preserves (marolo, soursop, and sweet passion fruit). Mixture design was used for product optimization and the preserves were evaluated by texture profile, stress relaxation test, and uniaxial compression test. The research data were analyzed using regression equations on SAS software. The results indicated that the rheological parameters were affected by the body agents. Erythritol should not be used as an isolated component because it provoked changes in the properties of the final product (harder and brittle preserves); xylitol and sorbitol made preserves more elastic, cohesive, and more fragile; and polydextrose showed a synergistic effect with erythritol for rupture deformation and lesser effects for hardness, adhesiveness, and gumminess.Item Desenvolvimento e avaliação de néctares mistos de abacaxi e gengibre.(2022) Lima, Natasha Nascimento; Souza, Edmara Moreira de; Santos, Paloma Cristina dos; Dias, Ana Clara Costa; Zinato, Matheus Macedo; Barbosa, Lais Cristina dos Santos; Cunha, Luciana Rodrigues da; Gandra, Kelly Moreira Bezerra; Pereira, Patrícia Aparecida PimentaConsiderando os benefícios proporcionados pelo gengibre e pelo abacaxi, esse trabalho teve como objetivo desenvolver e avaliar néctares mistos de abacaxi e gengibre desenvolver e avaliar néctares mistos de abacaxi e gengibre em relação às suas características sensoriais, físico-químicas e nutricionais afim de identificar a proporção ideal dos dois fatores em estudo no produto final. Foram avaliados os efeitos de dois fatores (abacaxi e gengibre), considerando delineamento central composto rotacional (DCCR) (22 + 4 pontos axiais + 3 pontos centrais). As formulações foram submetidas ao teste de aceitação avaliando os atributos cor, aparência, aroma, consistência, sabor e impressão global, utilizando-se a escala hedônica estruturada de 9 pontos e intenção de compra mediante escala de atitude. Foram realizadas análises de pH, sólidos solúveis totais, compostos fenólicos totais, atividade antioxidante pela metodologia de captura do radical DPPH e vitamina C. Os resultados foram avaliados por meio de superfície de resposta, teste de médias, mapa de preferência interno e função de desejabilidade. Verificou-se que a utilização do abacaxi e do gengibre, quando combinados, podem apresentar néctares mistos com melhores características sensoriais e nutricionais. Além disso, o uso dos dois fatores em produtos mistos é de extrema relevância, pois pode contribuir para o maior aproveitamento e agregação de valor para cada um deles coletivamente, em vez de individualmente. De acordo com a função de desejabilidade, o néctar com maior qualidade sensorial e nutricional deve conter entre 30% e 31,45% de abacaxi e 0,40% e 0,49% de gengibre.Item Piperine as therapeutic agent in paracetamol-induced hepatotoxicity in mice.(2022) Coelho, Aline Meireles; Queiroz, Isabela Ferreira; Perucci, Luiza Oliveira; Souza, Melina Oliveira de; Lima, Wanderson Geraldo; Silva, André Talvani Pedrosa da; Costa, Daniela CaldeiraHigh doses of paracetamol (APAP) can cause irreversible liver damage. Piperine (P) inhibits cytochrome P450, which is involved in the metabolism of various xenobiotics, including paracetamol. We evaluated the hepatoprotective effects of piperine with or without N-acetylcysteine (NAC) in APAP-induced hepatotoxicity. The mice were treated with two doses of piperine (P20 or P40) and/or NAC at 2 h after administration of APAP. The NAC+P20 and NAC+P40 groups showed a reduced area of necrosis, MMP-9 activity, and Casp-1 expression. Furthermore, the NAC+P20 group was the only treatment that reduced alanine aminotransferase (ALT) and increased the levels of sulfhydryl groups (-SH). In the NAC+P40 group, NLRP-3 expression was reduced. Aspartate aminotransferase (AST), thiobarbituric acid-reactive substances (TBARS), and IL-1β expression decreased in the NAC, NAC+P20, and NAC+P40 groups compared to the APAP group. The liver necrosis area, TNF levels, carbonylated protein, and IL-18 expression decreased in the P40, NAC, NAC+P20, and NAC+P40 groups compared to the APAP group. The cytokine IL-6 was reduced in all treatments. Piperine can be used in combination with NAC to treat APAP-induced hepatotoxicity.Item Elaboração de frozen yogurt simbiótico adicionado de gengibre.(2022) Quintão, Arthur de Oliveira; Lima, Michelle Barbosa; Schiassi, Maria Cecília Evangelista Vasconcelos; Curi, Paula Nogueira; Monteiro, Reginaldo de Souza; Cunha, Luciana Rodrigues da; Pereira, Patrícia Aparecida PimentaAtualmente, nota-se uma grande preocupação por parte dos consumidores em adquirir produtos nutritivos, saudáveis, que tragam benefícios para a saúde, com sabores diferenciados e acima de tudo, seguros para o consumo, sendo uma tendência de mercado e, como o sorvete de iogurte está cada vez mais sendo apreciado no Brasil, o presente estudo teve como objetivos a) determinar a concentração ideal de gengibre a ser adicionado ao frozen yogurt, b) determinar a concentração de prebióticos em frozen yogurt adicionado de gengibre e c) estudar a viabilidade das culturas lácticas, os teores de compostos bioativos e a capacidade antioxidante de frozen yogurt simbiótico adicionado de gengibre. Verificou-se que a utilização de 0,8% e 1,0% de gengibre adicionados antes ou após a maturação da calda não influenciaram a preferência do frozen yogurt. Já a adição de prebióticos, forma isolada ou combinada, influenciaram no pH, nos atributos sensoriais de cor e sabor e no overrun, sendo que a utilização de 2% de inulina proporcionou maiores teores de compostos fenólicos. Diante do exposto conclui-se que é viável produzir frozen yogurt simbiótico adicionado de gengibre. Desta forma, as quantidades ideais de gengibre e de prebiótico a ser adicionado ao produto são 1% e 2%, respectivamente.Item Antimicrobial and antioxidant activity of apricot (Mimusopsis comersonii) phenolic-rich extract and its application as an edible coating for fresh-cut vegetable preservation.(2022) Lima, Emília Maria França; Matsumura, Caroline Harumi Silva; Silva, Geovana Luísa da; Patrocínio, Isabela Cristina Soares; Santos, Catarina Angeli; Pereira, Patrícia Aparecida Pimenta; Hassimotto, Neuza Mariko Aymoto; Pinto, Uelinton Manoel; Cunha, Luciana Rodrigues daEdible coatings have several advantages in preserving foods, such as avoiding water loss, controlling microbial growth, and reducing the need for preservatives added directly to the product. Antimicrobial action can be obtained by adding antimicrobial substances including phenolic compounds commonly found in plant extracts. This study evaluated the phenolic compounds content, antioxidant and antimicrobial activity of pulp, and seed extracts of Mimusopsis comersonii (popularly known in Brazil as abrico), besides the phenolic compounds were identified and quantified in the pulp extract. Edible coatings were incorporated with pulp extract in order to evaluate the preservation of minimally processed apples and baroa potatoes against foodborne bacteria, and enzymatic browning was also determined. Myricetin-3-glucoside, quercetin-3-glucoside, and kaempferol-3-glucoside were identified as major flavonoids in the apricot pulp extract. The seed and pulp extracts inhibited all tested microorganisms, especially Staphylococcus aureus and Salmonella Typhimurium. Edible coatings added with 9% of phenolic extract showed in vitro antimicrobial activity, in addition to being effective in preventing enzymatic browning in minimally processed apples and baroa potatoes for up to 15 days of storage. They were also effective in reducing up to 2 log CFU/g of aerobic mesophiles after 15 days of storage for apples, even though no microbial inhibition in baroa potatoes was observed under the same conditions. The addition of pulp phenolic extract in edible coatings proved to be an alternative in the preservation of apples and in the antibrowning activity of minimally processed baroa potatoes.
