Moreover, highly significant negative correlations were found between FUR content and p -coumaric (−0.97, p < 0.05), catechin (−0.94, p < 0.05), rutin, gallic, ferulic, vanillic, and syringic acid (−0.93, p < 0.05) concentrations in the crumb and crust, indicating that they might be involved in the protein protection ( Table 3 ).
