Potential differences may exist between organic and conventional plant‐foods, including differences in nutritional qualities. Dietary sources of antioxidants have been correlated with a reduced risk of oxidative stress induced diseases, and thus have important health implications. This study aimed to determine in strawberries, if differences between growing methods or sampling season existed in antioxidant capacity, texture, or sensory attributes from consumers’ perspectives. Antioxidants were measured using the hydrophilic oxygen radical absorbing capacity (H‐ORAC FL ). H‐ORAC FL values for organic and conventional berries were 37.53 ± 7.63 μmol TE/g and 30.97 ± 9.22 μmol TE/g, and H‐ORAC FL values for May and August berries were 36.41 ± 9.36 μmol TE/g and 32.09 ± 8.31 μmol TE/g, respectively. Effects due to growing method and sampling season on H‐ORAC FL were not statistically significant. Panelists in May rated organic strawberries as significantly (p < 0.0023) crisper than those grown conventionally. Texture values showed strawberries in May were significantly (p ≤ 0.017) more firm than those in August. Results demonstrated a relevant, but not significant, trend for higher antioxidants in organic strawberries than conventional ones, suggesting organic strawberries may have a more beneficial health effect. However, nutritional intervention studies in humans are needed for further interpretation.
