Synopsis (short abstract) Starch is a carbohydrate polymer consisting of alarge number of glucose units linked together primarily by alpha 1-4 glucosidic bonds. The starch polymers come in two forms: linear (amylose)and branchedthrough alpha 1-6 glucosidic bonds (amylopectin), with each glucose unit possessing a maximum of three hydroxyls that can undergo chemical substitution. Hydroxypropyl starch is a modified starch. It is obtained by etherification of food starch with propylene oxide, in accordance with good manufact uring practice. Hydroxypropylation results in substitution of hydroxyl groups with 2-hydroxypropyl ether. Hydroxypropyl starch may additionally be subjected to acid, alkali, enzyme, or bleaching treatment in accordance with good manufacturing practice.

Enzyme-treated starch is a modified starch. It is obtained by treatment in accordance with good manufacturing practice, of food starch in an a queous solution at a temperature below the gelatinization point with one or more food-grade amyolyticenzymes.The alteration is a minor fragmentation.
