Özet
Six bread wheat varieties (modern wheats) widely grown in Turkey and nine different bread wheat varieties registered prior to 1970 (old wheats) were used in the present study. This study aimed to determine and compare the quality characteristics, dietary fiber contents and in vitro glycemic index of whole wheat breads produced using modern and old bread wheat varieties. The effect of xylanase on the quality, staling and dietary fiber content of whole wheat breads was also investigated. Mean sedimentation and modified sedimentation values, Farinograph development time, stability, quality number of whole wheat flours produced by modern wheats were higher than those of the old varieties. Whole wheat breads of modern varieties had higher mean volume and lower firmness values as compared to old varieties. Whole wheat breads of old wheat varieties had higher mean soluble dietary fiber content as compared to that of modern wheat varieties. Xylanase addition generally had an increasing effect on bread volume and soluble dietary fiber contents and a softening effect on firmness values. There were no significant differences between the mean (in vitro) glycemic index values of whole wheat breads produced from modern and old varieties. The results in the present study indicated that modern bread wheat varieties had better whole wheat bread making quality as compared with old bread wheat varieties. In addition, xylanase usage in whole wheat bread formula had an improving effect on whole wheat bread quality.
