PHYSICO-CHEMICAL CHANGES THAT OCCURS DURING FERMENTATION OF ARISHTAM (A HYDRO ALCOHOLIC CLASS OF DRUG OF AYURVEDA)
Journal Title: International Journal of Pharmacognosy - Year 2015, Vol 2, Issue 8
Abstract
The present study was to evaluate the physicochemical changes that take place in vasarishta during the manufacturing of the arishtams (hydro-alcohol class of drug of Ayurveda). The manufacturing process of the Arishtams usually takes 21 -30 days. The time period of the entire study was 21 days. Batch fermentation was done for a period of 14 days after which the fermentation process was inhibited using methods recommended in Ayurvedic literature and as per the company’s standard operating procedure. The arishtam was analysed for its physicochemical parameters periodically at an interval of 24 h. The parameters chosen for the physicochemical characterisation of the fermentation process were pH, Temperature, Specific gravity, Brix value, Sugar content, Alcohol content, Free amino acid content and Tannin content. The pH was found to vary between 4.30 and 5.57. The temperature was found to vary randomly between 25 ºC and 29 ºC throughout the period. The specific gravity was found to decrease drastically up to the 14th day followed by a gradual increase up to the 21st day. The brix value of the arishtam, on the other hand was found to decrease gradually up to the 14th day and then it maintained a constant value. The sugar content was found to gradually decrease over the period of fermentation while the alcohol content was found to increase up to day 16 followed by a drastic downfall. The free amino acid and tannin content were constantly fluctuating throughout the entire period. Using the values obtained from the experiments, an attempt has been made to understand a few physicochemical changes that take place in the vasarishta during fermentation.
