Comestibles prepared using 1,3-propanediol may include modified flavor profiles relative to comparable comestibles that do not include 1,3-propanediol. Further 1,3-propanediol may be used in low concentrations, such as about 0.01 to about 5 wt. % in comestibles to effect modification of flavor profiles including perception of oxidized whole grain wheat flavors and the like.
