ResumenSe elaboraron panes de molde con sustitución de harina de trigo por harina de zapallo (13%), siguiendo un diseño central compuesto rotacional 2 2 . Las variables independientes fueron glucosa oxidasa (0-20 ppm) y tiempo de cocción del zapallo antes de ser molido para la obtención de harina (0-20 min). Las variables dependientes fueron: volumen específico, color instrumental y contenido de almidón resistente. Se caracterizaron las mezclas de harinas en Mixolab y se realizó una prueba afectiva de aceptación. Los resultados indican que a mayor tiempo de cocción y valores medios de enzima aumenta la estabilidad de la masa. El debilitamiento de las proteínas aumentó con valores medios de enzima y mayor tiempo de cocción, mientras que la retrogradación del almidón disminuyó en las mismas condiciones. El volumen específico y el contenido de almidón resistente aumentaron con mayor tiempo de cocción. No hubo diferencia estadística significativa sensorial entre tratamientos. AbstractBread was made with wheat flour substitution for pumpkin flour (13%), following a central rotational composite design 2 2 . The independent variables were glucose oxidase (0-20 ppm) and cooking time of pumpkin before being ground to flour (0-20 min). The dependent variables were specific volume, instrumental color and content of resistant starch. The mixtures of flours were characterized in Mixolab and an acceptance test was carried out for sensory evaluation. The results showed that a longer cooking time and average enzyme values increase the stability of the dough. The weakening of the proteins increased with average enzyme values and longer cooking time, while retrogradation of the starch decreased under the same conditions. The specific volume and content of resistant starch increased with longer cooking time. There was no significant statistical difference between treatments in the sensory evaluation analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
