Disclosed herein are compositions containing a modified starch, the starch modified to contain ester linkages to multiple short-chain fatty acids of different lengths; in particular, containing linkages to acetate, propionate, and butyrate. Methods for making and using such starch esters are described, as are compositions including the starch ester for nutritional effects and health benefits.

Compounds encapsulated with octenylsuccinic anhydride modified starch and methods of forming the encapsulated compounds are provided. Poorly water-soluble compounds, especially pharmaceuticals, are solubilized within an oil phase, which is then formed into an emulsion with an aqueous phase comprising the OSA modified starch. The resulting emulsion can be dried, such as through spray drying, for form a powder comprising the encapsulated compound.

The method employs citric acid as the modifier, combines the citric acid with starch, achieves the good modification effect of starch at high temperature, and improves the digestion-resistant property of starch. Citric acid itself is nontoxic, the process conditions are mild and the treatment methods are relatively safe, which shows very high practical values. In the method, starch and citric acid are cross-linked by using the infrared treatment technology, and the dry heating treatment is used to promote the modifier citric acid into starch, thereby achieving significant and stable modification effects, and high modification efficiency.
