Phoenix dactylifera L. type Mariami from Iran was chosen for this study to investigate the solubility of its seed oil in supercritical carbon dioxide (SC-CO2). The seed has been discovered to possess an antioxidant. The extraction method using SC-CO2 solvent was used in this study to investigate the capabilities of supercritical fluid to extract Phoenix dactylifera L. seed oil since the method is clean compared with organic solvent extraction. Solubility of Phoenix dactilyfera seeds oil in SC-CO2 was correlated using empirical density based model with the help of IBM SPSS software for significance and correlation analysis of the models. Analysis of component in the oil was done using gas chromatography equipped with mass spectrometry (GC-MS). Oleic acid revealed to be the main fatty acid in Phoenix dactylifera seed oil, followed by palmitic acid, lauric acid, ascorbyl palmitate and others.

Scorbyl palmitate is a safty and highly efficient lipophilic antioxidant.It is produced by a novel ionic liquid method: L-ascorbic acid was esterified with palmitic acid to synthesize ascorbyl palmitate,using concentrated sulfuric acid as chemical catalyst in 1-Butyl-3-methy limidazolium terafluoroborate ([BMIM]BF4).The yield of ascorbyl palmitate reached 69.6±1%.

The effectiveness of several synthetic and natural antioxidants (AO) in inhibiting the oxidation of linseed oil has been studied. Under the conditions of accelerated oxidation at 100 °С, the values of the induction period of oxidation and stabilization factors of linseed oil in the presence of additives of known phenolic AOs, tocopherols, fat-soluble ascorbic acid esters and compositions based on them were determined. The data obtained indicate that ascorbic acid esters effectively inhibit the oxidation of linseed oil. The stabilizing effect of ascorbyl palmitate (AP) increases with an elevation in the content of α-linolenic acid in the oil and a decrease in the oxidative stability of the oil. One AP provided better stabilization efficiency than some known compositions based on it. Kinetic data on the accumulation of oxidation products in linseed oil with AP additives during the storage at room temperature and with free access of the air were obtained, demonstrating high inhibiting activity of AP under these conditions, which provides a possibility to increase the shelf life of the stabilized oil up to 18 months or more.
