Iramusu was used to make different types of Herbal drinks, which involves several unit operations. Therefore, it is difficult to prepare Herbal drinks for frequent consumption. In order to avoid those difficulties and hardships, several attempts were made to develop concentrated herbal drinks using dry Iramusu root. Experiments were carried out to prepare concentrated Herbal drink using maha Iramusu root. Also, several experiments and trails were conducted to find out the optimum extraction conditions, optimum Iramusu amounts, optimum sugar levels and suitable flavor combination to produce concentrated Iramusu herbal drink with 25 Brix value. Sensory evaluation tests were conducted to find out optimum levels and conditions for the above factors using 9-point Hedonic scale subjectively. Shelf life evaluation studies were carried out in Chemical and Microbiological aspects. Titratable acidity, pH and TSS were tested for Wi months of storage period at room temperature (27 ± 3 °C). After IV2 months Microbiology analysis were carried out. From the findings of this study, it can be concluded that the optimum extraction condition for Iramusu roots is lOOg of dry Iramusu roots with 500ml water and 30miri'tjoiling period. Optimum ingredient amounts that to be added for preparing 100ml of the herbal drink is, 40ml of extract with 20g of sugar level. Citric acid (0.25%) and salt (0.25%) combinated sample is the best sample, with good flavor enhancement capacity. The results revealed that the product was. acceptable for IV2 months and Coliform test was negative during this period. Total plate count was 30 per 1ml of concentrated herbal drink.
