Abstract: Starch was isolated from spontaneously fermented corn to study the effect of fermentation on physical properties of corn starch and the suitability of fermented corn for making starch noodle. Results showed that above 75 ℃,fermented samples have significantly lower swelling power than control samples. The peak viscosity and breakdown initially increase and then decrease,while final viscosity and setback decrease gradually with fermentation time extending. Fermented samples have significantly higher gel strength and noodles made from them have higher maximum tensile stress and maximum tensile strain. Results of sensory evaluation indicated that fermentation significantly improves the quality of corn starch noodle.

Key words: corn starch, starch noodle, spontaneous fermentation, tensile property
