Macronutrients, vitamins, minerals and bioactive compounds in fresh and dehydra...
Roberto, Poliana Miranda; Anunciação, Pamella Cristine; Della Lucia, Ceres Mattos; Pinheiro, Soraia Silva; Souza, Eliana Carla Gomes deBasil (Ocimum basilicum L.) is one of the most popular plants cultivated worldwide. It is a good source of natural antioxidants and contains significant amounts of important phytochemicals. Thus, this study aimed to evaluate the macronutrients, minerals, vitamins and bioactive compounds of fresh and dehydrated basil and its hot and cold infusions. The basil presented high moisture (94.12%) and low lipid (0.20%)...
A high fat diet does not affect the iron bioavailability in Wistar rats fed wit...
Silva, Bárbara Pereira da; Matyelka, Jéssika Camila da Silva; Moreira, Maria Eliza de Castro; Toledo, Renata Celi Lopes; Lucia, Ceres Mattos DellaThis study evaluated the effect of chia on the iron bioavailability and gene expression of proteins involved in iron metabolism in animals fed with a high fat diet and a standard diet. Four experimental groups were tested (n = 8): standard diet + ferrous sulfate (SD + FS), standard diet + chia (SD + C), high fat diet + ferrous sulfate (HFD + FS), high fat diet + chia (HFD + C). The hemoglobin gain, hemoglobin r...
Fortification of industrialized foods with vitamins
Liberato, Selma Coelho; Pinheiro-Sant'Ana, Helena MariaVitaminas são nutrientes essenciais à vida. Hábitos alimentares inadequados, alto consumo energético e falhas no metabolismo levam a deficiências de micronutrientes, que afetam mais de dois bilhões de pessoas mundialmente. O consumo, cada vez maior, de alimentos industrializados, somado à baixa estabilidade das vitaminas, têm induzido à prática de adição de nutrientes aos alimentos processados. Esta revisão dis...
Extruded sorghum consumption associated with a caloric restricted diet reduces ...
Cardoso, Leandro de Morais; Anunciação, Pamella Cristine; Alfenas, Rita de Cássia Gonçalves; Queiroz, Valéria Aparecida VieiraThis study aimed to evaluate the effect of sorghum intake on body composition and metabolic variables in overweight men. In a randomized controlled crossover study, 24 overweight men (25.6 ± 4.6 years) were randomly allocated into one of two treatments: extruded sorghum or extruded wheat. The study consisted of 2 periods of 8 weeks with at least 4 weeks of washout. Anthropometric, clinical and metabolic risk va...
Tocoferois e tocotrienois em óleos vegetais e ovos
Milagres, Regina Célia Rodrigues Miranda; Pinheiro-Sant'Ana, Helena Maria; Chaves, José Benício Paes; Guinaz, MicheleThe distribution and content of vitamin E isomers was investigated in vegetable oils and raw and cooked egg yolk in commercial restaurants. The analysis of the eight vitamin E isomers was carried out by High Performance Liquid Chromatography (HPLC) with fluorescence detection. The tocopherol and tocotrienol composition of foods varied considerably. Tocopherols were detected in greater quantity and frequency. Th...
Buriti of the cerrado of Minas Gerais, Brazil: physical and chemical characteri...
Hamacek, Fabiana Rossini; Dellla Lucia, Ceres Mattos; Silva, Bárbara Pereira da; Moreira, Ana Vládia Bandeira; Pinheiro-Sant'Ana, Helena MariaThe fruit species of the Brazilian Cerrado, such as buriti (Mauritia vinifera ), occupy a prominent position in the ecosystem since they contribute to the economic potential of the region and have high nutritional value. We aimed to evaluate the physical characteristics, chemical composition and content of vitamin C, carotenoids, vitamin E and folates in pulp of buriti from the Brazilian Cerrado of Minas Gerais...
Study of the physical and physicochemical characteristics of fruits of the licu...
Paula Filho, Galdino Xavier de; Barreira, Tibério Fontenelle; Rodrigues, Vívian Cristina da Cruz; Martino, Hércia Stampini DuarteThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri (Syagrus coronata (Mart.) Becc.). Titratable ac...
Phenolic compounds profile in sorghum processed by extrusion cooking and dry he...
Pinheiro, Soraia Silva; Cardoso, Leandro de Morais; Carvalho, Carlos Wanderlei Piler de; Queiroz, Valéria Aparecida Vieira; Menezes, Cícero Beserra deSorghum (Sorghum bicolor L.) is a gluten-free cereal that has the highest content of phenolic compounds among cereals. It needs to be processed prior to use for human consumption, which may change its antioxidant profile. The knowledge on the effects of extrusion and dry heat in a conventional oven on flavones, flavanones, and proanthocyanidins is limited. Thus, the content and stability to dry heat in a conven...
Otimização de método para análise de folatos em hortaliças folhosas por cromato...
Lucia, Ceres Mattos Della; Silva, Elizangela Rodrigues da; Ribeiro, Sônia Machado Rocha; Pinheiro-Sant'Ana, Helena MariaWe optimized a method for the determination of three main folate isoforms in leafy vegetables. Analysis was carried out by HPLC, using gradient of elution and fluorescence detection. Limits of quantification were 2 ng/mL; 2 ng/mL and 28 ng/mL for tetrahydrofolate (THF), 5-methyltetrahydrofolate (5-MTHF) and 5-formyltetrahydrofolate (5-FTHF), respectively. Recovery rates of THF, 5-MTHF and 5-FTHF varied from 87....
Perdas de vitamina C em hortaliças durante o armazenamento, preparo e distribui...
Moraes, Flávia Aparecida; Cota, Alessandra Miranda; Campos, Flávia Milagres; Pinheiro-Sant'Ana, Helena MariaO objetivo deste estudo foi avaliar perdas de vitamina C após etapas de manipulação de hortaliças, recepção, rmazenamento, preparo e distribuição, em restaurante institucional e comercial. Utilizou-se sete hortaliças: alface, cenoura, chicória, couve, couve-flor, repolho e tomate. A análise da vitamina C foi realizada por cromatografia líquida de alta eficiência (CLAE). As perdas cumulativas de vitamina C foram...
