Wheat germ oil is a unique source of highly concentrated nutrient; its beneficial active ingredients could have a substantial impact on human health considering the amount that is used in cooking. In this study, wheat germ oil was micronized with polyethylene glycol using particles from gas‐saturated solutions ( PGSS ) process and investigated functional materials content in particle changing different parameters. PGSS was carried out at temperatures of 40–50 C , pressures of 10–30 MPa and at different ratios (10:1, 5:1). The average particle size was found from 0.6330 ± 0.004 to 1.3506 ± 0.011 μm at a ratio of 10:1 and from 1.1776 ± 0.011 to 3.7680 ± 0.016 μm at a ratio of 5:1. In fatty acid compositions, linoleic acid was present and had the highest amount in all conditions after particle formation. Total phenolic compound and antioxidant capacity were also found in particles. Practical Application Wheat germ is mainly produced as a by‐product in the wheat milling industry. This by‐product is generally used as animal feed; however, it contains oil that contains high amounts of functional materials like polyunsaturated fatty acids and phenolic compounds that have practical uses in life. These have great health benefits for humans and can be used in products such as foods, biological insect control agents, pharmaceuticals and cosmetic formulations. But for protection from oxidation, preservation of bioactivity and because of control release and dose measurement, particle formation is the best way. Small particles of pharmaceuticals with a narrow particle size distribution play a vital role in the design of conventional drug delivery systems like tablets, capsules, injections and biphasic drug delivery systems.
