| 摘要 |
The present invention relates to a method for processing starch comprising a step of applying supercritical carbon dioxide to starch to perform extrusion molding; a starch processed by the method and having an adjusted pore size; and a food, a medicine, and an absorbent containing the starch having an adjustable pore size. When the method for adjusting a pore size of starch using a supercritical carbon dioxide system of the present invention is used, starch having a pore size reduced to 20-200 μm can be produced, thereby lowering the degree of expansion of starch and raising the water absorption index and thus increasing absorption force and adsorption force, reducing the gluten content in the starch, and increasing the solubility, so that a starch having high digestibility can be produced. Therefore, the present invention can be applied to starch mold manufacturing technology and control processing technology for controlling the microcellular type or the microcellular pore structure of starch, thereby being very usefully applicable in the food industry and the pharmaceutical industry. |
