Abstract

The objective of the research was to determine the effect of amount of extract purple sweet potato addition and drying time on physical, chemistry, and sensory characteristics of drink powder from extract purple sweet potato. Two factors were investigated, namely addition of extract purple sweet potato (30 mL and 40 mL) and the second factor was drying time (6 hours, 7 hours, and 8 hours). Observed parameters were physical (solubility, and color), chemical (water content, ash content, total sugar, and antioxidant activity) and sensory (aroma, taste, and color) characteristics. The research showed that the addiction of extract purple sweet potato factor had significant effect on water content, ash content, total sugar, color (lightness and yellowness), whereas drying time factor had significant effect on water content and color (lightness and yellowness). Interaction of the two factors showed significant effect on total sugar and hedonic characteristic (color and taste). Treatment of A2B1 (addition of extract purple sweet potato 40 mL and drying time 6 hours) was the best treatment with the following characteristics: water content 3.07 %, ash content 0.24%, antioxidant activity (IC50) 47.27 ppm, total sugar 50.13%, solubility value 98.27%, lightness 44.77%, redness value 14.50%, yellowness value 8.00%, and hedonic skor for aroma, color, and taste were 2.88 (like), 2.8 (like), and 2.68 (like), respectively.
