Hard and soft white wheat flour contained higher concentrations of free vanillic, syringic, and p-coumaric acids when compared to hard red wheat flour (Table 2). Additionally, the concentration of ferulic acid in the soft white wheat flour was higher than in the soft red wheat flour (Table 2). With few exceptions, the bread (crumb and crust) and crackers contained higher levels of free phenolic acids in comparison to the original flour. It has been reported that free phenolic acid content increases with baking and it is thought that thermal processing releases some of the bound phenolic acids, resulting in an increased concentration in baked products. Ferulic acid content specifically has been found to increase in baked pizza crust when compared with the original flour (Moore et al., 2009).
