Micronized whole wheat flour and xylanase application: dough properties and bread quality

The micronization process by jet mill of whole wheat flour in addition to xylanase application may be used to improve dough properties and baking quality. This study aimed to evaluate the dough formation and bakery performance of whole wheat flour micronized using jet mill and having different particle sizes and xylanase content A decrease in particle size increased water absorption and increased dough stability by 3.7 units. Increase in xylanase content decreased the dough stability and mixture tolerance, resulting in reduced strength. Although the dough quality reduced, this was not evident in bread quality. In bread, the increase in xylanase content increased the specific volume and improved the texture profile. The 158 and 261 μm particle sizes with 60 and 100 mg kg^-1 xylanase content reduced the undesirable effects of fibers in the dough, which may lead to improved bread making, thus enhancing improved consumer acceptance.
