- Abstract
Telang flower is a biopharmaceutical horticulture commodity known as a functional food source since it contains rich nutrients. The drying methods influence the physicochemical properties of this flower. This study aimed to investigate the physicochemical properties of telang flowers using the sun and oven drying methods. The standard procedures were used to determine water, pH, anthocyanin content, free radical inhibitory activity, and IC50. This study used a randomized design with one treatment factor: drying methods, including sun drying, sun drying with black cloth cover, and oven drying. The fresh telang flower served as the control. Furthermore, the best drying treatment was also evaluated using the De Garmo effectiveness index test. The results revealed that all drying procedures significantly differed in water content, pH, anthocyanin content, and IC50 values (p < 0.05). Meanwhile, all treatments’ free radical inhibitory activity did not differ significantly (p > 0.05). It was found that all treatments had IC50 values in the range of 36.48–49.67 ppm of antioxidant activity. Telang flowers were found to be very potent antioxidants. As a result of the effectiveness index test, the sun drying using a black cloth cover provided the best treatment with the characteristics of water content, pH, anthocyanin content, free radical inhibitory activity, and IC50 of 17.47%, 7.03, 0.085 mg/mL, 85.51%, and 49.67 ppm, respectively.
