Extraction of Iraqi Okra Seeds Oil and Study of its Properties During Different Periods

Abstract

This study includes making comparison of Physic-chemical properties between three types of local okra seeds (Abelmoschus esculentus L.). Oil which is (Petra, Batera and Husayniyah). The seeds were obtained from the local markets and diagnosed. Then they cleaned, dried and selected for homogeneous seeds in form and colour. The seeds were milled and the chemical composition measured including (moisture, ash, protein, oil and carbohydrate).The extraction of oil was carried out. The antioxidant properties of the extracted of oil were studied. The petra seed oil had the highest efficacy of 68%. While Husayniyah seed oil was higher than the other two types with the highest percentage of chelating ferrous ion, scavenging of hydrogen peroxide and reducing power 70.42%, 58.43% and 75.56% respectively. The extracted oil is than stored at 50?C for 60 days follow changes in its antioxidant properties during storage. All antioxidant traits had a significant decrease in the storage period, reaching the lowest values at the end of storage.
