Inulin and oligofructose exhibit valuable nutritional functional attributes, so they are used as supplements soluble fiber or macronutrient substitutes. As classic analytical methods for dietary measurement not effective, several specific have been proposed. These measure total fructans based on one more enzymatic sample treatments determination of released sugars. To determine inulin labeling purposes, we developed an easy rapid anion-exchange high-performance liquid chromatography (HPLC)...

Modifications of nutritional properties (amino acids, available lysine, protein digestibility, fatty fiber, inositol phosphate (IPs), free and bound phenolics, antioxidant properties) whole rice ingredients processed by soaking, germination, and/or extrusion cooking were evaluated. Soaking germination reduced proteins lixiviation hydrolysis, respectively. Lysine was the limiting amino acid. Polyunsaturated acids increased after germination. Protein digestibility 100% for germinated rice,...

Abstract Resistant starch can be used to reduce the availability of carbohydrates in baked products. In this study, effect type 4 resistant wheat ( RS ) on flour dough and breads was evaluated. Wheat substituted by at 10%, 20% 30% w/w 10, 20 30, respectively). Rheological thermal behaviours were Besides, bread quality, digestibility staling analysed. All exhibited viscoelastic behaviour but lower elastic viscous moduli. Regarding specific volume crumb texture negatively affected samples with...

The aim of this study was to evaluate the influence diets with different types fibres on Ca bioavailability and metabolic parameters in growing Wistar rats. Twenty four male rats were fed 3 diets: control (C), polydextrose (PD), extruded whole maize (M) during a 60 day period. Apparent absorption percentage (%Ca Abs), total skeleton bone mineral content (t BMC), density BMD), femur (F), spine (S) tibia (T) BMD, cecum weight, pH evaluated. Malondialdehyde (MDA) lipid (TG cholesterol) contents...

ABSTRACT The purpose of this work was to study the effect minimal doses γ‐irradiation reduce microbial loads (Co 60 , 0, 1.5, and 3 kGy) on flour from three rice cultivars with different amylose contents (AC) grown in Argentina: RP2 (AC 25%), Yeruá (Y) 19%), Higokumochi (H) 5%). Studies some starch characteristics such as digestibility (rate hydrolysis vitro), gel viscosity syneresis, scanning electron microscopy (SEM) were performed. Results showed that affects functional nutritive...

Brazil is the third largest producer of pineapple (Ananas comosus) and market for fresh sustained by Hawaii Perola cultivars. In this work cultivar was divided into three main parts, shell, core pulp, characterization. Moisture in pulp higher (between 10 15%) than shell core. The amount protein (35%) shell. contained relatively low concentrations total ascorbic acid edible although levels Citric corresponded to almost 60% organic acids. soluble sugars [~7-12% (FW)] were predominantly...

Functional bread with resistant starch and garlic improved the metabolism of calcium lipids growth beneficial gut microbiota.

The influence of diets with whole rice processed ingredients on cecum health, calcium absorption and bone parameters was studied using an animal model.

Summary The nutritional performance of wheat bread prepared with calcium carbonate and inulin was studied in growing rats fed three diets ( BD : diet containing inulin, SD synergy1 ® CD control‐ AIN 93G‐) up to 60 days. Animals consumed less presented a caecal pH (5.5) lower than that the group (7.0) highest amount anaerobic micro‐organisms (1.68 × 10 cfu g −1 ) at 23 Microbiota profiles DGGE indicated groups 66% similarity greater variability group, suggesting changes due prebiotic effect...

The aim of this work was to evaluate the effects resistant starch and garlic on technological quality wheat bread. Bread formulations with 20% (RS) 3% (G) both ingredients together (RS + G) were compared control bread (C). A decrease in specific volume crust color RS obtained while parameters increased by addition. Resistant led harder crumbs, softer ones. Besides, fresh crumbs had a more elastic structure (low elastics moduli high relaxation time) presented crunchiest crust. This shows that...

Purpose. To evaluate the effect of polydextrose (PDX) on Ca bioavailability and prevention loss bone mass. Methods. Twenty-four two-month-old ovariectomized rats were fed three isocaloric diets only varied in fiber source content up to 60 days (FOS group, a commercial mixture short- long-chain fructooligosaccharide, OVX group AIN 93 diet, PDX group). A SHAM was included as control. Apparent absorption percentage (%ABS), changes total skeleton mineral (tsBMC) density (BMD) femur BMD, % Bone...

Summary The effect of chemically modified resistant starch ( RS ) included in bread formulation on bone and gut health growing male Wistar rats was studied. In order to determine the functional properties prebiotic potential , three groups were assayed: a control group CD ), fed with diet including RSD containing BRSD ). Rats that consumed exhibited lower daily intake indicating more satiety is reached this food presented similar calcium absorption than rats. addition, an increase mineral...

The influence of whole grain (WG) rice based diets on the lipid profile and antioxidant status was evaluated.

The aim of the study was to analyze proximate composition pine nuts harvested from 15 growing areas in Chile, Argentina, Italy, Spain, Turkey, and Israel. main component fat, followed by protein. Pine Chile Argentina were similar, zones with highest thermal oscillation rainfall. Italian had fiber content, while Spanish fat content. Israel presented number dry months, where contained more protein minerals, Turkey showed an intermediate position. Minimum maximum average temperatures, amount...

Abstract Colonic effects of extruded whole-grain sorghum diets were evaluated using a model growing rats. In all, twenty-four male Wistar rats fed control (C), white (EWS) or red (ERS). Consumption showed satiety properties, with reduction caecal pH, and lower activity β -glucosidase -glucuronidase enzymes. Decreased copper zinc superoxide dismutase manganese increased catalase glutathione peroxidase levels observed in colonic mucosa. The induction antioxidant enzymes occurred through the...

Extruded refined sorghum flours have enough polyphenols and fermentable fibre to enhance colonic mucosa integrity promote an antioxidant environment.
