In vitro bioaccessibility of phenolic compounds and antioxidant activity in bio...
Barros,Nara Vanessa dos Anjos; Abreu,Bruna Barbosa de; Rocha,Maurisrael de Moura; Araújo,Marcos Antônio da Mota; Moreira-Araújo,Regilda Saraiva dos ReisABSTRACT The present work aimed to evaluate the contents of total phenolic compounds, total flavonoids and antioxidant activity, as well as to identify and quantify phenolic acids before and after simulated gastrointestinal digestion in vitro, in raw and cooked cowpea grains, of biofortified cultivars BRS Aracê and BRS Tumucumaque. The raw grains were analyzed as flour and the cooked grains were analyzed after ...
Cereal bar enriched with cowpea bean whole flour, cashew nut, and raisin banana
Moreira-Araújo,Regilda Saraiva dos Reis; Sousa,Iuska Grazielle Macêdo de; Cavalcante,Rodrigo Barbosa Monteiro; Morgano,Marcelo AntônioABSTRACT This work aimed to elaborate a cereal bar with whole cowpea flour, cashew nuts and bananas raisin and evaluate their acceptance and chemical composition. Three formulations were developed, B1 with 5.25% cowpea, B2 7.5% and B3 with 15%. Sensory attributes were assessed by 10 trained tasters using a hedonic scale. Two formulations were analyzed by 100 untrained tasters using the multiple comparison, pair...
Bioactive compounds and antioxidant activity three fruit species from the Brazi...
Moreira-Araújo,Regilda Saraiva dos Reis; Barros,Nara Vanessa dos Anjos; Porto,Rayssa Gabriela Costa Lima; Brandão,Amanda de Castro Amorim SerpaAbstract The aim of this study was to determine the content of bioactive compounds and antioxidant activity present in three fruit species from the Brazilian Cerrado: carnauba (Copernicia prunifera (Mill.) H.E. Moore), murici (Byrsonima crassifolia L. Rich)and oiti (Licania tomentosa (Benth) Fritsch). Among analyzed fruits, oiti showed the highest total phenolic content (1236.42 ± 34.06 mg GAE 100 g-1) followed...
Prevalência de Síndrome Metabólica e associação com estado nutricional em adole...
Mendes,Myrla Gabriela; Nascimento,Larisse Monteles; Gomes,Keila Rejane Oliveira; Moreira-Araújo,Regilda Saraiva dos ReisResumo Introdução A síndrome metabólica é uma desordem multifatorial relacionada, principalmente, com a deposição de gordura abdominal e as alterações da homeostase da glicose e/ou resistência à insulina. Estudos demonstram associações entre o excesso de peso na infância e as taxas de morbimortalidade elevadas na vida adulta; portanto, a presença de alterações metabólicas na infância e/ou na adolescência pode c...
Identification and quantification of antioxidant compounds in cowpea
Moreira-Araújo,Regilda Saraiva dos Reis; Sampaio,Geni Rodrigues; Soares,Rosana Aparecida Manólio; Silva,Cintia Pereira; Arêas,José Alfredo GomesABSTRACT Dietary antioxidant compounds have been widely studied because of their ability to delay or inhibit oxidative damage, which allows them to play an important role in the prevention of diseases and the promotion of health. The identification and characterization of such compounds are required before their use in humans. This study aimed to identify and quantify antioxidant compounds in the cowpea cultiva...
Effect of thermal processing on total polyphenol content in the grain of cowpea...
Cavalcante,Rodrigo Barbosa Monteiro; Araújo,Marcos Antônio da Mota; Rocha,Maurisrael de Moura; Silva,Kaesel Jackson Damasceno eABSTRACT Cowpea grain is noteworthy due to its functional properties, which are probably a result of the synergistic action of its nutrients and bioactive compounds. Since these compounds undergo the effects of thermal processing, the aim of the present study was to verify the influence of cooking on the total polyphenol content of the grain of cowpea cultivars. Samples were obtained from the experimental area ...
Chemical characterization of green grain before and after thermal processing in...
Melo,Natália Quaresma Costa; Moreira-Araújo,Regilda Saraiva dos Reis; Araújo,Marcos Antônio da Mota; Rocha,Maurisrael de MouraABSTRACT The cowpea (Vigna unguiculata (L.) Walp.) is one of the most widely consumed legumes in the North and Northeast of Brazil, representing an important source of protein, energy, fibre and minerals, in addition to generating employment and income. The aim of this study was to determine the chemical composition, and the effect of thermal processing on the green grain from biofortified cowpea cultivars. Sam...
Effect of cooking on the bioactive compounds and antioxidant activity in grains...
Barros,Nara Vanessa dos Anjos; Rocha,Maurisrael de Moura; Glória,Maria Beatriz Abreu; Araújo,Marcos Antônio da MotaABSTRACT The present study evaluated the effect of cooking on the levels of bioactives compounds and antioxidant activity in grains cowpea cultivars. The analysis were performed on the raw samples and after cooking in pressure cooker. Regarding the bioactive compounds present, the grain cultivar BRS Aracê exhibited the highest levels of total phenolic compounds (mg/100 g) both before and after cooking, 205.10 ±...
Cheese bread enriched with biofortified cowpea flour
Cavalcante,Rodrigo Barbosa Monteiro; Morgano,Marcelo Antônio; Silva,Kaesel Jackson Damasceno e; Rocha,Maurisrael de Moura; Araújo,Marcos Antônio da MotaABSTRACT The development and enrichment of food are of great importance not only for the industry but also to improve the population's nutrition, where you can create new products or optimize existing ones. The consumption of fortified products in the diet is an option for the control of deficiency diseases. This study aimed to develop enriched cheese bread with whole biofortified cowpea flour and evaluate thei...
