  • Glucoamylase converted starch derivatives and their use as emulsifying and encapsulating agents
    Patent number: 5935826
    Abstract: 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.
