In this study, total phenolic content was calculated as gallic
acid equivalents. However, ferulic acid may also have been used to
estimate the total phenolic content since it is the dominant phenolic
in cereal grains (Deng et al., 2012; Fardet et al., 2008;Holtekjølen, Knutsen, Preedy, Watson, & Patel, 2011).
