Use of fungal phytase to improve breadmaking performance of whole wheat bread
The possible use of phytase as a breadmaking improver has been tested in whole wheat breads by adding different amounts of fungal phytase. The effect of phytase addition on the fermentation stage and the final bread quality was analyzed. The phytase addition shortened the fermentation period, withou...
