Starches are polysaccharides produced by all green plants to store energy. They are the most important carbohydrates in the human diet, present in potatoes, wheat, maize (corn), and rice. Pure starch is a white powder insoluble in cold water. It consists of two types of molecules: the predominantly linear helical amylose (20-25%) and the lightly branched amylopectin (5-80%).

The study of native starches from different natural sources shows that GPC/SEC-MALLS can be used efficiently to perform molecular characterization and degradation monitoring.
