The study included 54 subjects who were selected through non-probabilistic sampling in three communities in the center of the State. Didactic material was developed which consisted of seven lessons in nutrition including concepts mentioned in the Health Belief Model and the Social Cognitive Theory. The lessons were applied to an intervened group (n = 27), taking other as control (n = 27). The pre and post test effect of the intervention was evaluated using a questionnaire, which was tested statistically with the Wilcoxon test. To compare differences between groups before and after intervention Mann-Whitney U statistic test was used.

The produced masas or doughs were subjected to chemical analysis, rheological and mechanical tests. Tortillas were manufactured from these doughs and mechanical tests were undertaken. Doughs from tubers had less protein and lipid content but higher nitrogen free extract than the control. All doughs presented weak viscoelastic gel-like behavior, with those of Mf behaving mainly as viscous systems. Doughs with Cf showed lower decrease in both the elastic (G') and viscous (G") moduli than those with Mf. The adhesiveness and cohesiveness of doughs with Mf showed a higher reduction of maximum force than those with Cf. Tortillas with Cf were more elastic with higher tensile strength than those with Mf. Using Cf as partial substitution of maize might lower production costs, but Mf is not particularly suitable as maize substitute in tortilla production. Tortillas with 40 % (w/w) cassava flour, presented the highest preference on a sensory test.

Hypertension is one of the most common worldwide diseases in humans. Angiotensin I-converting enzyme (ACE) plays an important role in regulating blood pressure andhypertension.An evaluationwas done on the effect ofAlcalase hydrolysis of defatted Jatropha curcas kernel meal on ACE inhibitory activity in the resulting hydrolysate and its purified fractions. Alcalase exhibited broad specificity and produced a protein hydrolysate with a 21.35 % degree of hydrolysis and 34.87 % ACE inhibition. Ultrafiltration of the hydrolysate produced peptide fractions with increased biological activity (24.46–61.41%). Hydrophobic residues contributed substantially to the peptides ’ inhibitory potency. The 5–10 and <1 kDa fractions were selec...

Quail egg white was dehydrated by air convection using one of two temperatures and times: M1 (65 ̊C, 3.5 h), M2 (65 ̊C, 5.0 h), M3 (70 ̊C, 3.5 h) and M4 (70 ̊C, 5.0 h). Lyophilized quail egg white was used as a standard. All four air-dried treatments had good protein levels (92.56% to 93.96%), with electrophoresis showing the predominant proteins to be lysozyme, ovalbumin and ovotransferin. Denaturation temperatures ranged from 81.16 ̊C to 83.85 ̊C and denaturation enthalpy values from 5.51 to 9.08 J/g. Treatments M1-4 had lower water-holding (0.90 2.95 g/g) and oil-holding (0.92 1.01 g/g) capacities than the lyophilized treatment (4.5 g/g, 1.95 g/g, respectively). Foaming capacity was pH-dependent in all five treatments, with the lowest values at alkaline pH and the highest (153% to 222%) at acid pH (pH 2). Foam stability was lowest at aci...

El objetivo del presente trabajo fue cuantificar el contenido de cuatro minerales en la duodeci-ma costilla de ovinos de pelo en pastoreo en el estado de Yu-catan durante la epoca de lluvias (junio-octubre). Se mues-trearon 50 predios de ovinocultores en 47 municipios y se recolectaron 139 muestras de costilla mediante biopsias. Se determino el contenido de Ca, K, Cu y Fe mediante espec-trofotometria de absorcion atomica. Los resultados se ana-lizaron estadisticamente usando un diseno experimental completamente al azar con un arreglo trifactorial incluyen-do el efecto de la zona geografica (Centro, Oriente, Poniente y Sur), el estado fisiologico de los ovinos (Destete,...

Type 2 diabetes is the most common, accounting for 95% of reported cases. The main objective of this article was to evaluate the in vitro antidiabetic effects of hydrolysates from Lima bean (Phaseolus lunatus L.) proteins. The hydrolysates were produced with either the Alcalase®-Flavourzyme® (AF) or pepsin-pancreatin (PP) sequential systems and peptide fractions (F > 10, F5-10, F3-5, 1–3 and 10 kDa fraction against α-amylase (IC50 = 54.61 ± 1.76 mg protein mL−1), the F5-10 kDa (IC50 = 124.14 ± 3.05) against α-glucosidase and the F5-10 kDa (IC50 = 1.93 ± 0.20) against DPP-IV. For the PP products, inhibitory activities were highest in the F < 1 kDa (IC50 = 55.79 ± 1.06). None of the highly inhibitory hydrolysates or peptide fractions exhibited cytotoxicity in vitro versus Vero cells. These fractions are potential ingredients for inclusion in ...

All treatments were analyzed to investigate the physical properties of the dough and tortillas as well as their physicochemical and nutritional quality. Results showed that cohesion was affected (p < 0.05) in the fortified tortillas made with CCF decreasing from 34.3 to 28.4 and 27.4 N for Control, L + T and PC + L + T, respectively; tortillas made with nixtamal showed no difference. Adhesion was not affected by treatments. Weight loss increased only in the fortified tortillas made with CCF (p < 0.05). Rolling capacity was not affected by fortification. The tension of tortillas increased with the fortification being the highes...

The diets contained each of the three minerals (Fe, S and Zn) at two levels, 647 mglkg, 0.3910 and 216 mglkg; versus 833 mglkg, 0.42% and 772 mglkg, respectively i n a 2 x 2~2 factorial design. Animal productivity as well as CU content of liver and kidney were not affected by the treatments, High levels of Fe reduced (P<0.05) Cu digestibility. The ceruloplasmin activity during the experiment also was reduced by the addition of S or Fe plus Zn. Results indicate that supplementation with S or Fe plus Zn may delay Cu intoxication of sheep consuming diets containing excess Cu.

Microcapsule behavior and properties differ between gums and description of non-conventional sources is needed to identify their potential applications. Flamboyant tree Delonix regia seed is not currently used as a commercial gum source, but carboxymethylated flamboyant seed gum (CFG) has properties similar to those of carboxymethylated guar gum. The

These diseases can be controlled through medication, yet the consumption of functional foods (FF) may be one complementary treatment option. Ingredients for this FF could be the pyrodextrin and enzymatically resistant maltodextrin (ERM), in this studio were obtained from modified native starch (NS) of M. cavendish.Objective: To evaluate the effects of modified banana starch on glycemic control and blood pressure in rats with high sucrose diet. Methods: We used 25 male Wistar rats that were fed with a high sucrose diet for 12 weeks. In the ninth week, the rats were divided into five groups: NC (negative control), PC (positive control), NS (native starch), PI (pyrodextrin), and ERM (enzymatically resistant maltodextrin). It was evaluated the glucose tolerance test, blood pressure (BP), insulin levels, total cholesterol, high-density lipoproteins (HDL), and triglycerides.Results: Di...
