NANO COMPOSITE FORMED FROM STARCH AND FUNCTIONAL MATERIALS, AND METHOD FOR PREPARING SAME

Document Type and Number:

WIPO Patent Application WO/2011/004944

Kind Code:

A9

Abstract:

The present invention relates to a method for preparing a nano particle by synthesizing a composite of starch or dextrin and various functional materials. The method comprises the steps of: dissolving starch or dextrin prepared from starch into water or a water-soluble solvent; dissolving functional materials to be included into a hydrophobic solvent; adding the hydrophobic solvent into the aqueous starch solution and agitating the result; forming a starch composite; eliminating residual starch; and collecting the starch composite, wherein some of the functional materials can be added directly to the aqueous starch solution, rather than be dissolved into the aqueous solution, thereby forming the starch composite. During the process of forming the composite, aggregation of starch or dextrin should be suppressed and the reaction rate needs to be controlled for including functional materials. The nano starch composite, which includes the functional materials, allows insoluble materials to be soluble and increases stability and in-vivo absorption, and is thus expected to have the effect of increasing the usefulness as products. Therefore, the nano starch composite can be used as a carrier, a coating agent, and a reinforcing agent for functional materials in various fields, such as fields of food, medicine, cosmetics, and chemical products.
