Abstract :

To investigate the effect of chitosan, salicylic acid, aloe vera gel and mallow extract treatments on the qualitative factors of mandarin and to determine their best concentration, a factorial experiment was conducted in a completely randomized design at the Islamic Azad University, Science and Research Branch. Experimental treatments included chitosan (0.5, 1 and 1.5%), salicylic acid (1, 1.5 and 2 mM), aloe vera gel (15, 30 and 45%) and mallow extract (15, 30 and 45%) ) were immersed and then stored for 45 days (storage period with 4 levels 0, 15, 30 and 45 days). Fruits juice pH, titratable acid, total soluble solids, fruit weight loss, carotenoids and ascorbic acid content and antioxidant capacity were measured. The results showed that during storage, the pH, total soluble solids, weight loss and carotenoids content increased and the amount of titratable acid, ascorbic acid and antioxidant capacity decreased. The most effective treatment in maintaining pH, titratable acid, soluble solids, carotenoid content, ascorbic acid and antioxidant capacity was salicylic acid 2mM, which is recommended for use after harvesting.
