  1. a Lac-88 and Lac-440 represent the hydrolysates that were treated with 88 mg and 440 mg laccase, respectively.
  2. b Lac-control and HRP-control represent the control hydrolysates for the treatments with laccase and horseradish peroxidase, respectively.
  3. c HRP-11.8 and HRP-59 represent the hydrolysates that were treated with 11.8 mg and 59 mg horseradish peroxidase, respectively.
