Overview

Isomalt (Palatinitol), a well-tolerated, non-toxic polyol and a protein-stabilizing excipient, stabilizes lactate dehydrogenase (LDH) moderately during freeze-drying, and performs better during storage. Isomalt is traditionally used as a sweetening agent in the food industry and as a tabletting excipient for pharmaceutical purposes.
