Abstract: In this study the cross-linked hydroxypropylated starch was synthesized from tapioca starch through the reaction of starch with propylene oxide and sodium trimetaphosphate (STMP). The transparency, freeze-thaw stability, anti-acid capability, high temperature-stability, and rheology characteristics were investigated. The effects of the cross-linkedhydroxypropylated tapioca starch to noodle was also studied. The results showed that the transparency, freeze-thaw stability, anti-acid capability, high temperature-stability and rheology characteristics are distinctly improved. The optimum cooking-time and cooking-loss of noodle after the addition of modified starch distinctly reduce.

Key words: tapioca starch, cross-linked hydroxypropylated starch, noodle
