The objective of this study was to determine the proximal composition, the physical and chemical characteristics and the in vitro antioxidant capacity (DPPH, ABTS and FRAP) of the pulp of the wild passion fruit (Passiflora glandulosa Cav.) from Cariri region, Ceara, Brazil. The results showed that the proximal composition and the caloric value of this passion fruit are similar to other species, but with a high ascorbic acid content. The fruit pulp showed low level of antioxidant activity and low level of polyphenolic compounds followed by three methodologies used. Due to high levels of titratable acidity (3.52) and total soluble solids (17.80° Brix), this fruit can be considered as a high value fruit for commerce. However, it is a species of passion fruit...

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...

Automated static image analysis as a novel tool in describing the physical properties of dietary fiber Ciênc. Tecnol. Aliment.
KUREK,Marcin Andrzej; PIWIŃSKA,Monika; WYRWISZ,Jarosław; WIERZBICKA,Agnieszka.
Abstract The growing interest in the usage of dietary fiber in food has caused the need to provide precise tools for describing its physical properties. This research examined two dietary fibers from oats and beets, respectively, in variable particle sizes. The application of automated static image analysis for describing the hydration properties and particle size distribution of dietary fiber was analyzed. Conventional tests for water holding capacity (WHC) were conducted. The particles were measured at two points: dry and after water soaking. The most significant water holding capacity (7.00 g water/g solid) was achieved by the smaller sized oat fiber. Conversely, the water holding capacity was highest (4.20 g water/g solid) in larger sized beet fiber....

Chemical composition and effects of micronized corn bran on iron bioavailability in rats Ciênc. Tecnol. Aliment.
Oliveira Junior,Gilson Irineu de; Costa,Neuza Maria Brunoro; Martino,Hércia Stampini Duarte; Paes,Maria Cristina Dias.
The degermination of corn grains by dry milling generates 5% of a fibrous residue. After segregation and micronization, corn bran becomes a potential source of dietary fiber consumption. However, its effect on iron bioavailability has not been reported in the literature. The objective of the present study was to determine the nutritional composition of corn bran and its effects on iron bioavailability using the hemoglobin depletion-repletion method in rats. The animals were divided into two groups: cellulose (control) and corn bran (experimental). The bran had high content of total dietary fiber, especially the insoluble fraction, and low phytate content. Hemoglobin uptake did not differ between groups at the end of repletion period, and the iron relative...

Contenido y caracterización reológica de los polisacáridos estructurales de nopalitos (Opuntia spp.) en un gradiente de domesticación. Colegio de Postgraduados
López Palacios, Cristian.
Evidencias diversas indican que la domesticación del género Opuntia comenzó con la selección de variantes de O. streptacantha, seguida de O. hyptiacantha y O. megacantha y se centró en O. albicarpa y O. ficus indica. Las causas por las cuales se domesticó Opuntia fueron por sus frutos y nopalitos. Los polisacáridos más abundantes en los nopalitos son del tipo estructural. La hipótesis que se plantea es que los polisacáridos muestran un gradiente de concentración y sus propiedades reológicas han sido modificadas en función del grado de domesticación de Opuntia. Los polisacáridos estructurales fueron extraídos de cladodios jóvenes de 14 variantes pertenecientes a especies representantes del gradiente de domesticación (O. streptacantha, O. hyptiacantha, O....

Silva,Jovane Santana; Marques,Tamara Rezende; Simão,Anderson Assaid; Corrêa,Angelita Duarte; Pinheiro,Ana Carla Marques; Silva,Renato Leal.
Pumpkin (Cucurbita maxima), popularly known as squash, is a widely grown vegetable in Brazil. In this study, pumpkin seed flours (PSF) with different granulometries were used: PSF 1 (medium granulometry) and PSF 2 (coarse granulometry) in the preparation of cereal bars (CB) with different combinations with brown oats. Five formulations were prepared: CB-1 (control - 25% brown oats and 0% PSF); CB-2 (12.5% PSF 1 and 12.5% brown oats); CB-3 (25% PSF 1 and 0% brown oats); CB-4 (12.5% PSF 2 and 12.5% brown oats); and CB-5 (25% PSF 2 and 0% brown oats). The acceptance test results were analyzed in a conventional preference mapping which indicated that the bars CB-2 and CB-5 received mostly the maximum hedonistic score. With the objective of developing a cereal...

Development of peach palm fibrous flour from the waste generated by the heart of palm agribusiness. Repositório Alice
HELM, C. V.; RAUPP, D. da S.; SANTOS, A. F. dos.
The consumption of fibrous foods has been stimulated in recent years. While wheat and oat brans are still the conventional sources of fiber for human consumption, other new fibrous products have been developed – at research level – from waste or by-products generated by food industries. This research aimed to develop a new dehydrated food product - peach palm fibrous flour - from the waste generated during the processing of the heart-of-peach palm. The average yield in dry weight from this waste into farinaceous products was 129.8 g kg-1. The flours showed high values for the total dietary fiber, 59.1 to 65.5 g 100 g-1, almost entirely represented by the insoluble fiber, as well as a low proportion of calories - 96.1 to 101.1 kcal or 408.2-429.5 kJ per 100...

Dietary fiber intake, stool frequency and colonic transit time in chronic functional constipation in children BJMBR
Guimarães,E.V.; Goulart,E.M.A.; Penna,F.J..
The objective of the present study was to evaluate associations between fiber intake, colonic transit time and stool frequency. Thirty-eight patients aged 4 to 14 years were submitted to alimentary evaluation and to measurement of colonic transit time. The median fiber intake of the total sample was age + 10.3 g/day. Only 18.4% of the subjects presented a daily dietary fiber intake below the levels recommended by the American Health Foundation. In this group, the median left colonic transit time was shorter than in the group with higher dietary fiber intake (11 vs 17 h, P = 0.067). The correlation between stool frequency and colonic transit time was negative and weak for left colon (r = -0.3, P = 0.04), and negative and moderate for rectosigmoid and total...

Digestive and functional properties of a partially hydrolyzed cassava solid waste with high insoluble fiber concentration Scientia Agricola
Raupp,Dorivaldo da Silva; Rosa,Danielle Amorim; Marques,Silvia Helena de Paula; Banzatto,David Ariovaldo.
Starch factories generate large amounts of cassava solid waste. A small amount is utilized for animal feed but most of it is discharged with deleterious effects to the envirounment. A edible food with a high content of insoluble dietary fiber (60.9%), named "partially hidrolyzed cassava waste" (PHCW), was prepared from industrial cassava solid waste by an enzymatic process. PHCW or wheat bran (WB) were fed to model rats and both promoted digestive function effects, but PHCW produced the greatest effect. The insoluble fiber constituent from PHCW (and not the soluble fiber), promoted the greatest fecal bulking, fecal weight and defecation frequency in rats, as compared to WB. Such results indicate that the partially hydrolyzed cassava waste presents...
