Abstract
Production of stable ozonized oils from unsaturated vegetable oils by introducing an ozone-oxygen mixture into the oil until it reaches saturation, and following the ozonization, an extraction process in acid medium is carried out in the presence of a redox reaction system, which is capable of moderately reacting the radicals in the presence of a synthetic or natural anti-oxidation medium or reducing medium.
Claims12
A process for producing stable ozonized oils from unsaturated vegetable oils comprising the steps of:
- placing an unsaturated vegetable oil in a vessel having means for bubbling a gaseous mixture therethrough:
- bubbling said gaseous mixture through said unsaturated vegetable oil to produce a saturated, ozonized oil, said unsaturated vegetable oil being maintained at a constant temperature and said gaseous mixture comprising ozone and oxygen:
- acidifying said ozonized oil;
- adding an aqueous solution of antioxidation or reducing agent;
- extracting undesirable by-products from said ozonized oil, said undesirable by-products being produced in said bubbling step, by shaking the mixture of said ozonized oil and said aqueous solution in the presence of a redox reaction system, said redox system selected from the group comprising ascorbic acid, vitamin E, vitamin A and a quinoid/benzoid system, said redox system being capable of radicalic reaction;
- and
- removing said aqueous solution, containing said undesirable by-products so that a stable ozonized oil containing beneficial peroxide products remains.
