PROCESS FOR PREPARING GRAIN IMPREGNATED WITH VALUABLE COMPOUNDS

摘要

Provided is a method for preparing functional grain impregnated with valuable compounds, wherein the prepared grain prevents loss of valuable compounds, keeps taste and flavor of grain intact, and thus is applicable to production of various functional foods. The method for preparing functional grain impregnated with valuable compounds comprises the steps of: (i) applying supercritical carbon dioxide to grain in a condition of 40-80‹C and 100-600bar to form fine pores from the surface to the inside of grain; (ii) applying supercritical carbon dioxide containing valuable compounds to the porous grain under the condition of 40-90‹C and 100-700bar to impregnate the porous grain with the valuable compounds; and (iii) converting the supercritical carbon dioxide applied to the grain into gas by reduced pressure, and then removing carbon dioxide gas.
