Abstract
The invention relates to a process for the production of a fraction containing oxidation-inhibiting substances from a vegetable material rich in these substances, to the fraction thus obtained and to its use for stabilizing food and cosmetic products against oxidation. The process is characterized in that the previously ground vegetable material or an extract of this vegetable material obtained with a light solvent, a distillation vehicle and an oil are mixed, the suspension is subjected to molecular distillation and a condensate containing the oxidation-inhibiting principles, the distillation vehicle and some of the oil used is collected.
