The current study, conducted at the Agriculture Research Institute Swat (ARI), aimed to evaluate the quality parameters of locally available orange juice brands in Swat. Physicochemical analysis, encompassing total soluble solids (TSS), moisture content, pH, and acidity, was performed on five samples. Results revealed that Sample II demonstrated the highest TSS at 15.2° Brix, with a moisture content exceeding 89%. pH values ranged from 3.62 to 3.39, and acidity levels varied between 0.28% and 0.38%. In summary, nestle orange juice, based on physicochemical analysis, emerged as the optimal choice for daily consumption due to its superior mineral and nutrient content.
