METHOD FOR PRODUCTION OF SMALL COLORED POTATO EXTRACT WITH ANTIOXIDATIVE MATERIALS

摘要

The present invention relates to a method for producing a small colored potato extract with an anti-oxidative material and, more specifically, to a method for producing a small colored potato extract with an anti-oxidative material, comprising: a step of obtaining a supercritical pressure extract by putting a small colored potato in a extracting device using supercritical pressure and extracting a small colored potato at 200 to 400 MPa pressure; and a step of hot-water extracting the supercritical pressure extract. The small colored potato extract containing a large amount of anti-oxidative material is produced by using the method of the present invention.
