Abstract :The present study is aimed to examine and compare the storage stability of seed kils extracted form red pepper insert ignore into journalissuearticles values(Capsicum annuum L.); waste by green techniques insert ignore into journalissuearticles values(cold pressing, ethanol solvent, and ultrasound-assisted ethanol solvent extraction);. In accordance with this purpose, the oil samples were stored for a period of 6 weeks at 60°C under accelerated conditions and analyzed at weekly intervals for peroxide, conjugated diene-triene values tok follow their oxidation stability. It was observed that the peroxide, oxidative induction time, conjugated diene, and triene values of seed kils were significantly influenced by the extraction processes insert ignore into journalissuearticles values(p<0.05);. The initial peroxide insert ignore into journalissuearticles values(9.83 meqO2 kg-1 oil);, conjugated diene insert ignore into journalissuearticles values(8.63);, and triene insert ignore into journalissuearticles values(3.36); values were higher in the oil extracted with ultrasound-assisted ethanol solvent extraction technique. At the end of accelerated oxidation conditions, the peroxide, conjugated diene, and triene values were ranked in the following order: ethanol solvent extraction insert ignore into journalissuearticles values(10 meqO2 kg-1, 7.31, and 3.76);, ultrasound-assisted ethanol solvent extraction insert ignore into journalissuearticles values(12.50 meqO2 kg-1, 8.87, and 4.02);, and cold press insert ignore into journalissuearticles values(28.50 meqO2 kg-1, 16.14, and 3.70);. However, the seed oil exhibited a high value of oxidative induction time in the oil extracted with ethanol solvent technique insert ignore into journalissuearticles values(30.11 min);. The results revealed that despite inherent anti-oxidative properties, red pepper seed kils can undergo some degree of auto-oxidation, which is dependent on the extraction method during storage. The best quality was preserved by the ethanol solvent extraction technique both in the first and the sixth week of storage.
