Whole grain wheat bread and bakery products is highly considered as a functional food due to the high amount of vitamins, minerals, and dietary fiber in whole wheat flour. However, as the lower end-use properties of whole wheat products limit consumer selection, it is required to measure the functionality of whole wheat flour. Thus, it is observed the fermentation properties of bread dough from the composite flour of whole grain and white wheat flour. Whole grain cv. Chokyeong developed in the NICS was ground using a hammer mill with 0.5 mm sieve. The composite flour was prepared by substituting wheat flour with whole grain flour at 15, 30, 45% levels. Breads were prepared using the 100 g composite flour according to a basic straight-dough mehtod (AACC 10-10A) with slight modification. A rheofermentometer was used to measure the maximum dough height (Hm) and the maximum gas formation (H’m) during fermentation. Also, total CO2 production was recorded. The Hm decreased from 38.8 to 27.5 (mm) with increasing whole wheat flour from 15 to 45%. Whereas, the H’m was increased from 61.7 to 60.8 (mm) with whole wheat flour increment. Total CO2 production was also decreased with increasing whole wheat flour ranging 1312∼1164 (ml). The fermentation results could be useful to partly predict the effect of substituting whole wheat flour on the end-use quality of pan-breads.
