Physico-chemical quality evaluation of commercial mango cultivars of Punjab, Pakistan during fruit ripening
Mango fruit quality at ripe stage significantly influences the consumers acceptance. Present study evaluated changes in fruit quality during ripening. Fruit physical (weight loss, ethylene production and respiration rate) and biochemical [soluble solids contents (SSC), titratable acidity (TA), ascorbic acid, sugars, antioxidants, carotenoids and phenolics] quality attributes of commercial mango cultivars were studied. Minimum weight loss (6.68%) was noted in White Chaunsa and maximum (22.30%) was found in Malda on ripening day-9. Respiration rates of the mango cultivars were ranged from 0.5 to 9.4 mmol CO2 kg‑1 h‑1 from day-1 to day-9 of the fruit ripening period. Mango fruit Rataul No. 12 had maximum rate of respiration (9.4 mmol CO2 kg‑1 h‑1); whereas, highest ethylene production was found in Malda mango fruit (0.70 mmol C2H4 kg‑1 h‑1). At day-9 during ripening, White Chaunsa exhibited maximum SSC (24.43 Brix°); whereas, minimum SSC (12.63 Brix°) was found in Dusehri. Total sugars were found maximum in Kala Chaunsa (27.39%) at ripening day-9 while, maximum ascorbic acid (399.57 mg 100 g‑1 FW) and total antioxidants (7.3 mM Trolox g‑1 FW) were observed in Langra at ripening day-5 and day-1. Minimum total carotenoids (0.02 mg 100 g‑1) were found in Rataul No. 12 at ripening day-1; whereas, Anwar Rataul showed maximum (1.98 mg 100 g‑1 FW) carotenoids at day-3. In case of total phenolics, Langra had maximum phenolic contents (145.5 mg 100 g‑1 FW) and Anwar Rataul has minimum (68.43 mg 100 g‑1 FW). Overall, Samar Bahisht Chaunsa, Langra, Kala Chaunsa and White Chaunsa excelled in physico-chemical attributes with maximum eating quality after 7 days of ripening.
