Abstract

Corn plant is suitable to cultivate on suboptimal land due to it’s resistance to acid and dry soil. The objective of the research was to determine the effect of time soaking corn kernels and addition of water to corn flour on characteristics of instant corn rice. Corn that is used is from the farmers of Arisanjaya village (the area of suboptimal land agriculture). The research used a Factorial Completely Randomized Design with two treatment factors and three replications. The observed treatment factor was soaking time (A1: 6 hours, A2: 12 hours, A3: 24 hours) and the addition of water (B1: 80%, B2: 90%, B3: 100%). Observed parameters were physical (color, texture and length of serving), chemical (moisture, ash) and sensory characteristics with hedonic test (texture, color and flavor). The results showed that the soaking time had significant effect on lightness, chroma and ash content of instant corn rice. The addition water had significant effect on the chroma of instant corn rice. The interaction between the soaking time and addition of water had significant effect on the chroma of instant corn rice. The treatment A1B3 (6 hour soaking time and the addition of water 100%) was the best treatment with the average color values (49.77% lightness, 21.40% chroma, 65.200 hue), 76.73 gf cooked corn rice texture, 9.67 minute length of serving, 4.36% moisture content, 1,01 % ash content, the average value of hedonic test (2.20 texture, 2.56 color, and 1.88 flavor).

Abstract

Syafutri et al, 2019. Physicochemical Properties of Colorant from Water Hyacinth Flower (Eichhornia crassipes) Extracted by Microwave Assisted Extraction (MAE) Method. JLSO 8(1):94-106.The objective of this research was to determine the effect of oven microwave power and extraction time on color intensity, anthocyanin stability, and antioxidant activity of colorant from water hyacinth flower (Eichhornia crassipes) extracted by microwave assisted extraction (MAE) method. The research was conducted at Agricultural Product Chemical Laboratory, Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University. The experiment used a Factorial Completely Randomized Design with two factors and each treatment was repeated three times.  The first factor was oven microwave power (100 watts and 300 watts) and the second factor was extraction time in oven microwave (1 minute, 2 minutes, and 3 minutes). The parameters were color intensity, anthocyanin stability, and antioxidant activity. The results showed that the oven microwave power and extraction time had significant effects on color intensity and antioxidant activity. The increasing of oven microwave power and extraction time increased a* value and antioxidant activity, and decreased b* value, significantly. The result also showed that the anthocyanin compounds was not stable with heating up to 105°C.
