Addition of toasted baru nut (Dypteryx alata Vog.) and extruded rice bran to sugar cane candy (“rapadura”) Ciênc. Tecnol. Aliment.
SILVA,Célia Caroline Florindo da; SILVA,Giselle de Lima Paixão e; SOARES JÚNIOR,Manoel Soares; BELÉIA,Adelaide Del Pino; CALIARI,Márcio.
Abstract Different proportions of sugar cane juice, toasted baru nut and extruded rice bran were used in the formulation of sugar cane candies (“rapaduras”), and the effect on color, hardness and proximate composition determined. The best formulation was selected on the basis of composition, hardness and luminosity, and evaluated for sensory acceptance and purchase intent. Simplex design was used to plan the experiment and the limits of the different ingredients. Sugar cane juice has lower values for ash, protein, lipids and total fiber compared to the other ingredients, but it is the ingredient that characterizes the product. The added ingredients affect the physical and chemical characteristics of the “rapaduras”. The hardness of the experimental...

Application of roasted rice bran in cereal bars Ciênc. Tecnol. Aliment.
Garcia,Marina Costa; Lobato,Luciana Pereira; Benassi,Marta de Toledo; Soares Júnior,Manoel Soares.
The objective of this study was to evaluate the viability of using microwave-roasted rice bran as an ingredient in high-fiber cereal bars to obtain a product with good acceptability. The influence of the rice flakes, corn flakes, and roasted rice bran levels on the physical and chemical characteristics of the cereal bars was studied. The overall acceptability of three selected formulations was also evaluated. An increase in the roasted rice bran level in the formulation reduced the force of rupture and water activity, resulted in intermediate density, and caused darkening of the bars. The contents of lipid and total dietary fiber were higher in the formulation with the highest rice bran content, which was therefore classified as functional food. The...

Abstract Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to the multiple uses of its pulp and seeds in the food and cosmetic industries. This fruit generates large amounts of solid waste, which, despite of its high content of bioactive compounds, is discarded in the environment. Therefore, with the aim of reusing these wastes and adding economic value, we investigated the nutritional potential of the seed by-product resulting from industrial cupuassu oil extraction. The by-product was submitted to green extraction, and its contents of bioactive compounds were quantified by HPLC. The extract had a total polyphenol content (16.9 ± 1.8 mg/gDM) and an antioxidant activity, ABTS + (151.0 ± 5.5 mg/100 g) and DPPH. (85.4...

Chemical characterization of the flour of peel and seed from two papaya cultivars Ciênc. Tecnol. Aliment.
Santos,Cláudia Mendes dos; Abreu,Celeste Maria Patto de; Freire,Juliana Mesquita; Queiroz,Estela de Rezende; Mendonça,Marcelle Mendes.
Papaya is among the currently most important tropical fruits grown in Brazil and in the world. The fruit is mainly consumed fresh although it offers many industrial products. The processing of this fruit, as well as its fresh consumption, results in large amounts of waste, such as peels and seeds. Papaya consumption is one of the causes of significant loss of food value; therefore, new aspects on the use of its waste as by-products, or in the production of food additives, or even the incorporation of its flour in food have aroused great interest because these are products of high nutritional value, and their use may be economically viable. The objective of this study was to produce and characterize peel and seed flours from two papaya cultivars (Havai and...

Santos,Lilian Dena dos; Zadinelo,Izabel Volkweis; Moesch,Augusto; Bombardelli,Robie Allan; Meurer,Fabio.
Abstract: The objective of this work was to evaluate the use of crude glycerol as an energy source to replace corn, in diets for Nile tilapia (Oreochromis niloticus) in the fattening stage. Two hundred Nile tilapia (190±4.5 g) were distributed in 20 tanks, in a completely randomized design. The treatments consisted of crude glycerol at 0, 60, 120, 180, and 240 g kg-1, to replace the dietary levels of corn, in order to maintain a constant digestible energy. Fish productive performance and the chemical composition of the fillet were evaluated. Histological analyses of the hepatopancreas, intestine, and visceral fat were also carried out. Crude glycerol had no effect on the performance parameters; however, it caused a quadratic reduction of visceral fat....

Effect of the addition of peach palm (Bactris gasipaes) peel flour on the color and sensory properties of cakes Ciênc. Tecnol. Aliment.
MARTÍNEZ-GIRÓN,Jader; FIGUEROA-MOLANO,Ana María; ORDÓÑEZ-SANTOS,Luis Eduardo.
Abstract This study aimed to evaluate the color and sensorial characteristics of a cake made with different amounts of flour made with peach palm peel flour. The flour was added at different concentrations, 2.5, 5.0, 7.5, and 10% (w/w), including a control (tartrazine). Physiochemical analyses were carried out on the cakes, including total carotenoids, CIE-L*a*b* color coordinates, and sensorial attributes. The results demonstrated that the peach palm peel flour substitution increased the total carotenoid content of the cakes. The color test showed that high levels of peach palm peel flour resulted in a decrease in the values of lightness (L*) and hue angle (h°), while the values of browning index (BI) and color change (ΔE*) increased significantly. The...
