Preparing Method of Sorghum Extract having High Antioxidant Activity and the Sorghum Extract having High Antioxidant Activity thereby

摘要

The present invention relates to a method for preparing a sorghum extract having enhanced antioxidant activity and the sorghum extract having enhanced antioxidant activity prepared thereby and, more specifically, to a method for preparing a sorghum extract having enhanced antioxidant activity by extracting a sorghum extract using ethanol or fermented ethanol as an extractant and then applying pressure and heat to the extract at a predetermined temperature and pressure for a period of time, and to the sorghum extract prepared by the method. As the sorghum extract prepared by the preparation method of the present invention contains the sorghum treated with pressure and heat, the sorghum extract contains higher levels of total polyphenols and flavonoids and has enhanced antioxidant activity compared to sorghum not treated with pressure and heat, thereby being able to be used as a new functional ingredient and develop new consumer demand for sorghum having little uses except for multigrain rice.
