ABSTRACT:
Antioxidant substances are obtained from vegetable matter by mixing vegetable matter containing antioxidant substances with a C.sub.2 -C.sub.6 alkylene glycol and subjecting the mixture to pressure of at least 40 bar to obtain a liquid extract. In carrying out the process, the vegetable matter mixed with the alkylene glycol has a moisture content of from 5% to 30% by weight. Further, to subject the mixture to pressure, the mixture is pressed, and additionally, the process includes filtering the extract to obtain a clear extract.
