A Comparison Between Ascorbylpalmitateen Capsulated With Nanoliposomeas a Natural Antioxidant and Conventional Antioxidants (TBHQ and BHA) inthe Oxidative Stability ofSunflower Oil

摘要

To improve the storage stability, sunflower oil containing poly unsaturated fatty acids (PUFAs) was encapsulated by using ascorbylpalmitate encapsulated with nanoliposomes (APEWN). Ascorbylpalmitate was selected as the wall material because it showedabetter antioxidant activity. Microcapsules were prepared and compared with common antioxidants such as BHT and TBHQ.Rancimat method was used for the initial screening of the antioxidant activity. Free fatty acids (FFA), peroxide value (PV), anisidine value and Iodine value of the samples were monitored. The Results showed micro encapsulation of ascorbylpalmitate was suitable for preventing sunflower oil from oxidizing in comparison with TBHQ and BHT.
