Effects of L-Ascorbic Acid on Wheat Bran Bread Quality
Abstract
In this research, effects of different levels (0, 50, 75, 100, 125, and 150 mg/kg) of
L-Ascorbic Acid (L-AA) on the some wheat bran bread quality characteristics such as loaf volume,
grain structure, bread firmness and bread moisture were investigated. Mechanical dough development
method was used during bread making and wheat bran was added to wheat flour at 0, 10, and 20%
levels. L-AA was increased loaf volumes when it was used up to 100 mg/kg, however further
increasing of L-AA level was lead to decrease at loaf volumes. Improvement at grain structure was
obtained when L-AA was used at 100 mg/kg in the control breads while at 10% wheat bran breads
this improvement was detected at both usage levels 75 and 100 mg/kg of L-AA. Beside these, increase
at bread softness was determined as from the 50 mg/kg level of L-AA but there is no significant effect
(p>0.01) of different L-AA levels was found on bread moisture content. When L-AA was used at over
dosage it was effect wheat bran bread quality characteristics negatively. So, it should be used carefully
and bakeries should be avoid to its over dosage addition.
