Taro (Colocasia esculanta L.) flour can be mixed with arenga starch in noodle making with 25% taro flour and 75% arenga starch as the best proportion. Addition of beetroot extract as red natural color may improve consumer preference and change the noodle characteristic. This research purpose is to know the effect of addition of beetroot extract on the noodle characteristic. Coloring extraction was done using 5 variances of beetroot (0.4; 0.6; 0.8; 1; and 1.2 g (fresh weight/ml water). Then, noodle was made and characteristic including physical and sensory properties were evaluated. The result showed that coloring extracts addition decreased the break compression, elongation, and tensile strength of arenga starch-taro flour sohun. Beetroot extract addition increased the red color and didn't change sensory properties significantly.
