PHYSICO-CHEMICAL AND SENSORY PROFILING OF PROMISING MANGO CULTIVARS GROWN IN PERI-URBAN AREAS OF MULTAN, PAKISTAN

Abstract

In the present scenario, Pakistani mango is facing serious apprehension about production decline and export, consequently present study was planned to categorize the paramount mango (Mangifera indica L.) cultivar in relation to its physical, chemical and sensorial attributes. Physiologically fully mature fruits of eight mango cultivars were picked and subjected for physical and proximate analysis. Among the eight cultivars, Fajri produced the maximum green and ripe fruit weight, fruit length and perimeter and physiological weight loss (453.0g, 403.0g, 13.80 cm, 21.57cm and 10.97%), respectively. The higher softness values were noticed in Aman Dusahri. The mark variations were observed among all the cultivars for proximate composition. There is an increase in pH values (5.47, 5.40 and 5.33) among Samar Bahisht Chaunsa, Aman Dusahri and Anwar Ratual, respectively with a progressive decrease in ascorbic acid and titrable acidity during ripening period. Likewise, maximum moisture and ash contents were observed in the mango pulp of Fajri and Sindhri (92.20% and 0.78%, respectively). Whereas appreciably higher total sugar contents were observed in pulp of Langra, Samar Bahisht Chaunsa and Anwar Ratual (20.67%, 20.43% and 20.33%, respectively. 19.83% TSS and 0.64% protein contents were recorded in Langra while the Fajri contained higher fat contents. The sensorial attributes varied significantly according to cultivars. Out of eight cultivars Langra obtained higher scores, while Anwar Ratual found to be highly satisfactory followed by Samar Bahisht Chunsa for flavor and taste. Both of these cultivars were equally acceptable for overall acceptability. However non of the cultivar is rejected by the panelists regarding the sensory evaluation.
