Abstract
Water soluble, lipophilic starches are provided, which comprise a mixture of functionalized high and low molecular weight maltodextrin molecules. The starches may be formed by dispersing a granular starch in a liquid medium to form a slurry that is simultaneously cooked and subjected to enzyme hydrolysis. Following hydrolysis, the starch is functionalized with an organic acid anhydride reagent, such as octenylsuccinic anhydride. The organic acid anhydride substitution occurs randomly and at various locations within the maltodextrin molecules.
