The present invention relates to modified starches which are prepared by enzymatic hydrolysis of a starch molecule using glucoamylase 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 glucoamylase. Such modified starches are useful as emulsifying and/or 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. |
