Abstract: The rheological properties of Ginkgo biloba L. starch (GBLS) were primary studied. The results showed that the apparent viscosity of Ginkgo biloba L. starch paste solution is higher when the concentration increases and heating temperature decreases. Their starch paste property is in accordance with the Not-Newton fluidity law, and being of a different degree of thixotropy. Comparing with the corn starch, the settling capacity of 1% Ginkgo biloba L. starch is faster, with the settle value 30%(V/V). The rupturing capacity and the modulus of elasticity of 6% Ginkgo biloba L. seed starch gelatin are 1.801N and 0.181×105N/m2 respectively.
