Abstract
This research aimed to study the effects of 1% addition of various hydrocolloids, i.e. guar gum, carboxymethylcellulose (CMC), and Arabic gum, in preparing noodles from Canna edulis starch modified with heat moisture treatment (HMT) in advance. Research results showed that some parameters such as cooking loss were not affected by hydrocolloid except Arabic gum (which resulted in the highest cooking loss). CMC and Arabic gum significantly affected the hardness and elasticity of starch noodles; meanwhile, for the stickiness parameter, guar gum gave the lowest stickiness of starch noodles and was not significantly different from native Canna edulis starch noodles. The addition of hydrocolloids did not significantly affect tensile strength except for the brightness of noodles. From the sensory evaluation perspective, Canna edulis modified starch noodle was likely to be more accepted by the panelists than other starch noodles available in the market.
