Abstract

This study aimed to determine the effects of microwave power and drying time on the physicochemical characteristics of dried butterfly pea flowers (Clitoria ternatea L.). The method used in this study was a Factorial Completely Randomized Design with two treatment factors, factor A microwave power (360 watts and 450 watts), and factor B drying durations (8 minutes, 12 minutes, and 16 minutes). Each treatment combination was repeated 3 times. The observed parameters were physical characteristics (yield and color L*, a*, b*) and chemical characteristics (pH, moisture content, antioxidant activity, and total anthocyanins). The results showed that microwave power significantly affected yield, color (L*, a*, b*), pH, moisture content, antioxidant activity, and total anthocyanins, whereas drying duration significantly influenced yield, color (L*, a*, b*), pH, moisture content, antioxidant activity, and total anthocyanins. The interaction between microwave power and drying duration had a significant effect on blueness (-b*), antioxidant activity, and total anthocyanins. The best treatment in this study was A1B1 (360 watts of microwave power for 8 minute), resulting in an antioxidant activity value (IC50) 113.78 ppm, total anthocyanins 12.24 mg/L, lightness (L*) 47.73%, redness (a*) 7.25, blueness (-b*) -13.85, yield 10.11%, moisture content 15.65%, and a pH 5.96.
