| Se evaluó el efecto que produjo en la calidad del pan la reducción de azúcar en la fórmula, sin hacer otras variaciones importantes en el proceso tecnológico. Se emplearon dos calidades de harina diferentes y se aplicó la fórmula con el azúcar a 4 % (base harina) y también con 2 y 0 %, el resto de los ingredientes fueron: harina 100 %, agua 52 %, sal 2 %, grasa 1 %, levadura seca y mejorador 0,3 %. Los panes se elaboraron a escala de laboratorio, por el método directo, con 1 kg de harina. Los análisis que se realizaron a los panes fueron: humedad, volumen específico, altura, diámetro, penetrabilidad de la miga y evaluación sensorial. Con la harina de peor calidad se afectó significativamente (p≤0,05) el color de la corteza y la dureza del pan al disminuir... |

| It is important to understand how changes in the product formulation can modify its characteristics. Thus, the objective of this study was to investigate the effect of whey protein concentrate (WPC) on the texture of fat-free dairy desserts. The correlation between instrumental and sensory measurements was also investigated. Four formulations were prepared with different WPC concentrations (0, 1.5, 3.0, and 4.5 wt. (%)) and were evaluated using the texture profile analysis (TPA) and rheology. Thickness was evaluated by nine trained panelists. Formulations containing WPC showed higher firmness, elasticity, chewiness, and gumminess and clearly differed from the control as indicated by principal component analysis (PCA). Flow behavior was characterized as... |

| Abstract Common beans are rich in protein and complex carbohydrates that are valuable for the human diet. Starch is the most abundant individual component; however, in its native form it has limited applications and modifications are necessary to overcome technological restrictions. The aim of this study was to evaluate the influence of oxidation, acetylation and dual-modification (oxidation-acetylation) on the physicochemical, structural and thermal properties of common bean starch. The degree of substitution of the acetylated starches was compatible with food use. Fourier transform infrared spectra confirmed the acetylation of the bean starch, with a peak at 1,735cm-1. The granules of the bean starch were oval to spherical in shape, with no differences... |
