Starch Derivatization addresses the large possibilities of starch as an industrial raw material.

Starch Derivatization describes a number of new developments and addresses topics such as:

• Relation between granular structure and derivatization
• Derivatization in aqueous alcohol
• New starch esters
• Use of spacers in derivatization
• Enzymatic derivatization

Starch Derivatization is intended for the (industrial) starch researcher as well as for those professionals interested in the derivatization and application of polysaccharides and natural polymers.
