Antioxidant profile of the dry dog foods

Food	Total phenolic content a (mg gallic acid/100 g sample)	Total antioxidant capacity by ABTS b (μmol Trolox/100 g sample)	Total antioxidant capacity by ORAC c (μmol Trolox/100 g sample)
A	225.97 ± 1.06	3718.09 ± 81.54	2755.16 ± 99.97
B	133.25 ± 4.39	2648.21 ± 61.4	1551.93 ± 79.85
C	130.82 ± 0.88	3122.91 ± 30.77	1792.56 ± 58.05
D	155.18 ± 2.15	3156.58 ± 61.49	2644.59 ± 126.56

Abbreviation: ORAC, oxygen radical absorbance capacity.

^a Total phenolic content was measured by Folin–Ciocalteu method.

^b ABTS: total antioxidant capacity measured by discoloration test with ABTS^•+ cation radical.

^c ORAC: total antioxidant capacity measured by the ORAC assay. The results are expressed as the mean ± standard error of the mean (SEM).
