Elaboraci贸n de pan multigrano con harinas precocidas por extrusi贸n = Multigrain bread processing with extruded flours
Se estudi贸 el efecto en la calidad del pan seg煤n el proceso de elaboraci贸n y del nivel de sustituci贸n (20%, 36%) de una harina precocida por extrusi贸n preparada en base a combinaci贸n de avena, soja y salvado de trigo en la calidad del pan. Se caracteriz贸 la harina compuesta seg煤n sus propiedades funcionales (脥ndice de Absorci贸n de Agua), granulometr铆a y propiedades nutricionales (prote铆na, fibra total, fibra soluble, cenizas, materia grasa). Se realiz贸 seguimiento del volumen, 铆ndice de blancura, medidas reol贸gicas (dureza, cohesividad, elasticidad y masticabilidad) de los panes. Las condiciones del proceso de elaboraci贸n fue lo que gener贸 mayor impacto en la calidad del pan. Los cambios operativos realizados provocaron un incremento del 37% en el volumen, 6% de elasticidad y 15% de cohesividad, y una disminuci贸n del 44% de dureza y 34% de masticabilidad. Esta tendencia se mantuvo en los cuatro d铆as siguientes al d铆a de elaboraci贸n. El nivel de sustituci贸n de harina compuesta no provoc贸 cambios significativos en la dureza, elasticidad y masticabilidad del pan, pero se observaron cambios en la cohesividad y volumen. El pan con 36% de sustituci贸n result贸 un 7% menos cohesivo y con un 27% menos de volumen que el de 20% de sustituci贸n
Elaboraci贸n de pan multigrano con harinas precocidas por extrusi贸n
The effect in bread quality of a new bread making process and two replacement levels (20%, 36%) of refined wheat flour by extrusion precooked prepared based on combination of oats, soybeans and wheat bran was studied. Composite flour was characterized according to its functional properties (water absorption index), grain size and nutritional properties (protein, total fiber, soluble fiber, ash, fat). The volume, whiteness index, rheological measurements (hardness, cohesiveness, springiness and chewiness) of the bread were monitored. No significant changes were recorded in hardness, elasticity and chewiness of bread according to the level of substitution of composite flour; bread with 36% substitution was 7% less cohesive, with 27% less volume bread with 20% substitution. The process conditions caused greatest impact on the quality of bread. The new process resulted in a 37% increase in volume, 6% elasticity, 15% of cohesiveness and 44% decrease in hardness and 34% in chewiness, compared to the traditional process. This trend continued in the four days following the date of processing. The substitution level of composite flour did not cause significant changes in hardness, elasticity and chewiness of bread, but changes were observed in cohesiveness and volume. Bread with 36% substitution was 7% less cohesive, with 27% less volume than the 20% substitution.Se estudi贸 el efecto en la calidad del pan seg煤n el proceso de elaboraci贸n y del nivel de sustituci贸n (20%, 36%) de una harina precocida por extrusi贸n preparada en base a combinaci贸n de avena, soja y salvado de trigo en la calidad del pan.
