Use of an enzymatically-converted starch derivative as an encapsulating agent

摘要

The present invention relates to modified starches which are prepared by enzymatic hydrolysis of a starch molecule after the preparation of a starch derivative containing a hydrophobic group or both a hydrophobic and a hydrophilic group, particularly octenyl succinic anhydride starch hydrolyzed by beta -amylase or glucoamylase. Such modified starches are useful as encapsulating agents, particularly in systems where high load and retention of the active ingredient, low surface oil exposure, and excellent oxidation resistance is desired. The encapsulating agents are useful in a variety of applications including a tablet in which the starch allows for good compressibility and hardness.
