Octenyl succinic andride can be used to esterify Starch to yield a drocolloid with amphiphilic properties, octenyl succinylated starch (OS-starch). Octenyl succinic andride (OSA) modification affects interaction between molecules on the outer surfaces of two starch granules by altering molecular structures on the outer surfaces[1].
