Abstract

An application of carboxymethylcellulose (CMC, degree of substitution 0.6 and purity 99%),produced from rice straw was investigated. CMC with particle size of 0.15-0.3, 0.075-0.15 and less than0.075 mm in diameter were added into chinese dough product (Patongco) at 5% (by flour weight). Theresult indicated that the Patongco, added the less than 0.075 mm particle, was accepted by consumer.Finally, the smallest particle size of CMC was then added into Patongco at level of 0, 3, 6 and 9% (by flourweight). Patongco was accepted by consumer at 6% CMC addition and decreased oil uptake about 23%,compared with control.
