摘要

The present study was conducted to investigate the comparative physiochemical analysis and quality assessment of different commercial brands of grape juices available in the local market of Peshawar. Five samples were analyzed for physiochemical characteristics like total soluble solids, moisture, ash, pH, acidity, total sugars, reducing sugars and non-reducing sugars. Different commercial brands of grape juices were collected from the local market of Peshawar. It was observed that TSS of sample II was higher i.e. (16.3° brix) and sample III was found to have lower TSS i.e. (12.1 ° brix). Maximum moisture contents were observed in sample III i.e. (88.326%) and minimum moisture was observed in sample II i.e. (84.012%). Ash contents were observed higher in sample V (0.244%) and were lower in sample IV (9.6 x 10'6 %). pH was in the range of (2.51 to 3.01). Maximum pH was in sample V and minimum was in sample IV. Acidity of the samples was found higher in sample IV i.e. (0.6%) and lower in sample III i.e. (0.33%). Total sugars of these samples were found maximum in sample IV (18.69%) and were minimum in sample III (13, 74%), Reducing sugars was high in sample IV (18.48%) and lower in sample III (11.03%). Non reducing sugars were maximum in sample III (2.71 %) and minimum in sample I (0.16%). Highest TPC were found in sample I (25 cfu/ml). TCB and FCB were found in normal range in all samples. E.Coli were absent in all samples.
