A study was conducted to prepare and standardize the recipe of blended RTS based on different proportion of swallow root extract, banana juice (100:00, 00:100, 20:80 and 40:60) and also with pomegranate juice (00:50:50, 20:40:40 and 40:30:30). Physico and bio-chemical properties these different blends are studied at 0, 30, 60 and 90 days after storage and showed the statistically significant variation among all the blends. The maximum desirable results were obtained from RTS blend of T6 (swallow root extract, banana juice and pomegranate juice 20:40:40) showed TSS (15.23 ̊brix), titratable acidity (0.64%), ascorbic acid (9.11 mg/100 ml), anthocyanins (4.37 mg/100 ml), bacterial count (1.00×106 cfu/ ml) and overall acceptability (9.03) which was followed by the RTS blend of T7 (swallow root extract, banana juice and pomegranate juice 40:30:30). From 0 to 90 days after storage, TSS and microbial count increased gradually where as titrable acidity, ascorbic acid content, anthocyanins and overall acceptability decreased gradually in all the RTS blends.
