Abstract :

The goal of this study was the extraction of oil from by-products (tomato waste, apricot kernel and peach kernel) for determination of more bioactive micronutrients components and oxidative stability. Tocopherols and phytosterols were analyzed by HPLC and GLC respectively. In addition fatty acid composition was evaluated in these oils. Concerning phytosterols, β-sitosterol was major component in all oils extracted from non-traditional sources. The fatty acid composition of lipids from apricot kernels varied from other oils. The oleic acid in apricot kernel oil was higher than oil from tomato waste and peach kernel oil. Concerning the vitamin E, it was found that tomato waste contain highest amount of gamma-tocotrienols. Results showed that the apricot kernel oil the highest oxidative stability as shown from its induction period compared to the other investigated oils. The results of this study demonstrated that oil from wastes and kernels is a potential source of considerable amounts of tocopherols, tocotrienols and phytosterols. This oil could be utilized into various food products and cosmetics offering health benefits.
