Efficacy of Gum Arabic as an esculent film on shelf life extension of tomato (Solanum lycopersicum L) fruit

Titilope Abosede Fashanu, A. T. Oladiji, O. A. Peters


Effect of Gum Arabic (GA) as a non-toxic outer layer to prolong the shelf-life of tomato was carried out in the present study. Tomatoes were coated with 0% (Control) (A), 5% w/v (B), 10% w/v (C), 15% w/v (D) and 20% w/v (E) GA and stored at ambient (33°C; 70%). The polygalacturonase and β-galacturonase activities were carried out. Weight loss, titratable acidity, pH, lycopene, β-Carotene and antioxidant property of the fruits were determined at day 0, 5, 10, 15 and 20 during the experimental duration. Results indicated that polygalacturonase activity ranged from 0.753-1.138 unit/mg, β-galacturonase activity ranged from 1.55-2.78 x 103 miller units, β-carotene ranged from 1.78-23.89 mg/g, antioxidant property ranged from 66.26-192.12μg/g, titratable acidity was from 0.595-0.95% while the lycopene ranged from 0.77-17.62 mg/g. These results showed that control had significant rapid weight loss with faster rate of softening while the tomatoes coated with GA demonstrated a significant (p<0.05) deferment in ripening as well as maintained its nutritional quality up to 20 days. This indicates that GA may be utilized as an edible coating for tomato.

Key words: Edible film, Gum Arabic, ripening, shelf life.
