Abstract:

Organoleptic and physico-chemical analysis was undertaken to analyze three apple varieties commonly found in the local market of district Gilgit, Pakistan. Different parameters investigated include moisture content, ash content, total soluble solids, pH value, acidity, reducing sugar, total sugar, mineral elements etc. Research revealed that moisture content in Golden Delicious-GD (87.71%) is higher than Five Star-FS (78.99%) and Nazak Badan-NB (84.81%). Ash content found 0.29% (GD), 2.89% (FS) and 0.35% (NB). Similarly, total soluble solids were 10.2 (GD), 11.4 (FS) and 9.5 (NB). Moreover, fat content in GD (1.24%), FS (2.13%) and 1.87% (NB).  pH value recorded was 3.69 in GD, 3.89 in FS and 3.44 in NB. Acidity, in GD (0.285%), 0.19% (FS) and 0.15% (NB). Mean valves of reducing sugar in in GD, FS and NB were (10.70%, 15.13%, 12.53%) respectively. Furthermore, total sugar in GD (10.70%), FS (15.13%) and NB (12.53%).The chemical values of fruits showed a higher content of mineral elements and also a good quality for the products obtained from the local market of district Gilgit. Based on the results research recommends for Jam, Juice and pulp production without any health risk.
