Toplam 129 atıf DOI
Antioxidant effects of essential oils from rosemary (Rosmarinus officinalis), clove (Syzygium aromaticum) and cinnamon (Cinnamomum zeylanicum) were determined on hazelnut and poppy oils. These essential oils were added to the oils at concentrations of 0.25% and 0.5%. Butylated hydroxyanisole (BHA) at 0.02% level served as standard besides the control groups for comparison. The samples were stored 50°C in darkness for 14 days. The antioxidant activity of the essential oils was determined by measuring peroxide values (meq O 2/kg oil) at regular intervals. On the basis of peroxide value assay, the essential oils showed stronger antioxidant effect when compared to control groups. BHA was more effective than the essential oils, whilst it exhibited no antioxidative effect on the first few days of storage. Amongst the investigated essential oils, the cinnamon oil was the most effective on retarding lipid oxidation of crude oils, which was followed by clove and rosemary oils.

The effect of several essential oils, plant extracts and packaging materials on oxidative stability of virgin olive oil during different storage times was investigated. The formation of free radicals, changing of color, development of rancid odor and taste are formed as a result of the oxidation of stored oils due to the effect of oxygen and light in the environment depending on the properties of the packaging materials used. As the storage time progressed, viscosity, color, free fatty acid, peroxide and K232 values were increased. The highest increase in K270 value was found in the first month whereas the value of p-anisidine was found to be maximum in the second and third months of storage. The highest acidity (1.91%) and discoloration were observed in the samples stored in the glass-pet bottle while the highest viscosity (99.80 mPa s), peroxide (12.00 meq O2/kg), K232 (0.73) and K270 (0.11) values are found in the samples stored in the tin. The highest free fatty acid values of samples stored in glass bottles, PET bottles and tin were detected in olive oils added rosemary. The peroxide values of the samples stored in glass and pet bottles decreased at 1st month and increased as the storage process progressed.
