Abstract
We determined the bactericidal activity of surface applied waxes on oranges. Effective bactericidal activity of combined alkali and heat treatments was observed on both glass slides and orange fruit surfaces. A five log reduction of Escherichia coli was attained by dipping inoculated glass slides in heated (≥50°C) alkaline (pH 10) wax solution for 4 min. A pH 11, dipping at ≥50°C for ≥2 min achieved similar bactericidal effects. On the fruit surface, wax treatments were effective at the non‐stem scar area. Thus, applied fruit waxes may be useful on raw agricultural commodities to reduce surface microbial contaminants.
