Cassava pulp and pomelo peel were evaluated for their potential as sources of dietary fibre in dried rice noodles. Noodles containing cassava pulp (1–20%) and pomelo peel (1–10%) had significantly higher cooking weight (136–166%) than the control sample (125%). Elongation of noodles containing cassava pulp (61–86%) was significantly higher than that of the control (56%) and noodles containing pomelo peel (29–49%). Total dietary fibre (TDF) content of noodles made from rice flour was 3.0%, and increased to 7.0% and 10.2% after adding 20% of cassava pulp and 10% of pomelo peel, respectively. A combination of cassava pulp and pomelo peel at a total amount of 20% resulted in an obvious increase in cooking weight, whereas tensile stress and elongation of noodles were comparable to those of the control noodle. The highest TDF content obtained was 14.4%.
