WGH-B	0.310 ± 0.014^a	0.240 ± 0.032^a	0.161 ± 0.018^a
WGH-C	0.484 ± 0.025^c	0.739 ± 0.028^c	0.148 ± 0.019^a
WGH-D	0.545 ± 0.019^d	1.157 ± 0.036^d	0.262 ± 0.022^b

^aEach value is the mean ± standard deviation of triplicate determinations. Means with different letters in the column for each antioxidant activity assay are significantly different. WGH-A, supernatant of wheat gluten hydrolysate; WGH-B, WGH-C and WGH-D, 0, 20 and 40% ethanol elution fractions of WGH-A on XAD-16 resin, respectively
