Abstract
Introduction. Natural beverages face strong competition from synthetic drinks in the open market. Creation of diversity in natural products is a key strategy to withstand this competition. Pummelo (Citrus grandis Linn.) is one such potential fruit which could be exploited on a commercial scale if processed properly. The bitterness of pummelo juice is a serious handicap in its utilization. The present study aimed at preparation of a cost-effective, palatable blended beverage of pummelo. Materials and methods. To overcome this problem, pummelo was blended with mango ginger and kokum juice in the ratio of [65:30:5] for the preparation of syrup. The product was stored for 120 days in ambient conditions of storage and analyzed for changes in its physicochemical constituents. Results and discussion. Total soluble solids and total sugar increased during storage, while titratable acidity and ascorbic acid content decreased slightly during storage. Organoleptically, the best recipe was 25% juice, 70 °Brix total soluble solids and 1.5% acidity with a score of 6.3 out of 7.0 for overall acceptability. Mango ginger juice suppressed the bitter aftertaste of pummelo juice and imparted its characteristic taste and flavor to the product. The product was shelf-stable and had important medicinal constituents in it. The [total revenue / total cost] ratio of the product was 2.90.
