Effects of high-pressure homogenization process on the surface reactive phenolic contents and antioxidant activities of wheat bran.

Wheat bran sample	Surface-reactive phenolic content (mg GAE /g d.w.)	DPPH scavenging activity (umol Trolox equiv/g d.w.)	ABTS scavenging activity (umol Trolox equiv/g d.w.)	Ferrous ion-chelating activity (EDTA umol/g d.w.)
Gound raw	3.4±0.02a	8.2±0.1a	12.7±0.2a	22.1±0.1
IC200, 1-pass	6.9±0.03b	20.0±0.2b	27.5±0.1b	17.0±0.2
IC100, 2-pass	9.1±0.03c	24.5±0.2c	36.3±0.1c	16.9±0.2
IC100, 5-pass	11.8±0.04d	32.8±0.1d	40.1±0.2d	15.3±0.2
IC100, 7-pass	12.4±0.03e	37.9±0.1e	45.3±0.1e	15.4±0.1

The values are expressed as mean±SD (n=3).
Means with the same letter in column are not significantly different by duncan’s multiple range test (p<0.05).
