Abstract

The purpose of this research was to determine the effect of extraction time and oven microwave power on color intensity, antioxidant activity, yield, total phenol, pH, total dissolve solid, browning index, water content, and color stability. The research was conducted from February to April 2021 at Agricultural Product Chemical Laboratory, and Processing Laboratory, Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University. This study used a factorial Completely Randomized Design (CRD) with two factors and each treatment was repeated three times. The first factor was extraction time (2, 4, 6, 8 minutes) and the second factor was oven power microwave (100 watt and 300 watt). Observed parameters were color intensity, antioxidant activity, yield, total phenol, pH, total dissolve solid, browning index, water contents, and color stability. The research showed that the extraction time had significant effect on color intensity (yellowness, redness, lightness), antioxidant activity, yield, total phenol, pH, total dissolve solid,and browning indeks, but not had significant effect on water contents. The power of oven microwave had significant effect on color intensity (yellowness, redness, lightness), antioxidant activity, yield, total phenol, pH, dan browning index, but not had significant effect on water contents. While the interaction between the two treatments had not significant effect on the extraction time and the power of oven microwave. Keywords: Extraction time, Power of microwave, Sappan wood
