Studies have been carried out to find potential sources of natural
antioxidants in wheat breads. Fan et al. (2006) evaluated antioxidant
property and quality of breads containing Auricularia
auricular polysaccharide (AAP) flour. The incorporation of AAP in
bread markedly increased the antioxidant activity of bread as
tested by DPPH free radical scavenging method. HoltekjØlen,
Bævre, RØdbotten, Berg, and Knutsen (2008) studied antioxidant
properties and sensory profiles of breads in which 40% wheat flour
was replaced with barley flour. The incorporation of barley increased
the antioxidant properties of the breads and the sensory
evaluation showed differences among sensory attributes, depending
on the barley variety used. There was a good consistency between
the sensory attributes and the amount of phenolics in
barley wheat bread. Lin, Liu, Yu, Lin, and Mau (2009) found that
the buckwheat could be incorporated into wheat bread to get better
functional composition and improved antioxidant properties in
bread.
