Starch consists of the polysaccharides amylose and amylopectin. Their different solubility in water makes it possible to separate these two components from one another by heating the starch with water and pouring the warm solution through a pleated filter. Due to its poor solubility in water, the undissolved amylopectin is trapped by the filter while the aqueous amylose solution collects in the glass beaker.
