| description | The quality of newly harvested wheat and the changes that may occur during grain storage is of interest to the milling industry. The objective of this work was to study the variations in the industrial quality of durum wheat from the moment of its harvest throughout 7 months of storage. Grain and semolina parameters such as hectoliter weight, one thousand kernel weight, protein, moisture, milling yield, falling number, color, wet and dry gluten content, gluten index and farinograph properties were determined. Grain moisture was below 14% during storage time. Fluctuations of semolina extraction rates during the first months of storage were observed. Extraction values varied from 66 to 73%, stabilizing in 72% at 120 days from harvest. The falling number also presented an increasing tendency. The other quality parameters including gluten and farinograph, showed no significant variations during the storage time. The results indicate that there is no evidence of changes in quality parameters except for milling yield. This suggests the positive effect of blending old wheat with new wheat to minimize fluctuations in milling parameters. |

La calidad del trigo recién cosechado y las fluctuaciones que puede sufrir durante el almacenamiento resultan temas de interés en la industria molinera. El objetivo de este trabajo fue estudiar los cambios producidos en la calidad industrial del trigo candeal (Triticum durum L.) recién cosechado y durante siete meses de almacenamiento. Los parámetros de grano y sémola determinados fueron: peso hectolitro, peso de mil granos, proteína, humedad, rendimiento molinero, falling number, color, contenido de gluten húmedo y seco, índice de gluten y propiedades farinográficas. La humedad del grano se mantuvo por debajo del 14% durante el tiempo de almacenamiento. Se observaron fluctuaciones en las tasas de extracción de sémola durante los primeros meses de ensayo. Los valores de extracción variaron desde el 66 al 73%, estabilizándose en 72% a los 120 días de la cosecha. El falling number también presentó una tendencia creciente. El resto de los parámetros de calidad, incluyendo gluten y farinograma, no mostraron variaciones significativas durante el almacenamiento. Los resultados indican que no hay evidencia de cambios en los parámetros de calidad, excepto en la extracción de sémola. Esto sugiere el efecto positivo de mezclar trigo viejo con trigo nuevo para minimizar fluctuaciones en los parámetros de molienda.
