Rice is a complex mixture.

∙ 13y agoYou ask a very complex question.
A good place to start is the basic priciple that any compound naturally produced is a mixture since there will always be small amounts of residual compounds. Starch contains 2 families of compounds, amylose and amylopectic, these are both long chains of repeating glucose units with diffrent intermolecular bonds. The compounds are polymers, ie a long chain of repeating units and hence, there is also a variety in the number of repeating units in each of the compounds, the trait is called the "polydispersity" of the polymer.
So the correct answer would be that starch is a mixture of mixtures.
Cornstarch is a pure substance because it is composed of a single type of molecule, which is starch.
