ABSTRACT
Background: Tomato processing industry are dedicated to the preparation of tomato concentrates and their derivatives. Tomato processing byproduct, also known as tomato pomace (peel and seeds) represents around 5–30% of the main product. If these wastes remain unused, they not only add to the disposal problem, but also aggravate environmental pollution. Methods: In this research, physical-chemical characteristics of peel and seeds extracts of tomatoes cultivated in the region of Souss-Massa, are studied to evaluate the possibility of production and exploitation of oil and bioactive compounds that constitute these extracts obtained by Soxhlet extraction using polar and non-polar solvents. Results: The seed oil extracted has a dark yellowish color and obtained with a yield of 14.53%. Its measured characteristics revealed that this oil is perfectly beneficial nutritionally to human health due to its richness in unsaturated fatty acids and has quality parameters close to those indicated in the Codex Alimentarius of fats and oils. The content of total phenolics in the extracts was determined spectrometrically according to the Folin−Ciocalteu procedure and calculated as gallic acid equivalents (GAE). Among extracts obtained, remarkable high antioxidant activity and high total phenolic content (GAE > 20 mg/g) were found in peel extracts compared to seeds extracts. The antiradical activity of peel and seeds extracts was evaluated by the DPPH test. The overall results showed that the methanol peel extract has strong antioxidant capacity with EC50 reached Conclusion: To fully exploit these important sources of natural antioxidants, further characterization of the phenolic composition is necessary. But overall, these results remain useful for developing standards on these materials.
Keywords: Valorization; Tomato pomace; residues; extraction; Soxhlet.
