Abstract

Cold-pressed vegetable oils possess high nutritional benefits but are highly susceptible to oxidation due to their high content of unsaturated fatty acids and minimal processing. Oxidation of oils leads to rancidity and nutrient loss, which limits shelf life and compromises the quality. The aim of this study is to investigate the potential of celery (Apium graveolens), leaf and root, as natural antioxidants to enhance the oxidative stability of cold-pressed rapeseed oil during storage. The oil samples with added fresh celery leaf or celery root, were stored for one and two weeks in dark and light conditions. The rapeseed oils were stored in bottles with different oil volumes (1 L, 750 mL, 500 mL and 250 mL). In addition, control samples without celery addition were also prepared and stored under the same conditions to compare the effect of celery. Peroxide value (PV) was used to measure the oxidation. Statistical analysis using ANOVA was performed to check if the differences between the groups were significant. Results have shown that PV increased with the storage time in all samples. Oxidation was higher in oils exposed to light and stored in smaller volumes. Compared to the control oil samples, samples with celery addition showed lover peroxide values, especially when stored in dark and in larger oil volume bottles. Oils with celery leaf added have greater oxidative stability than oils with celery root added, in both dark and light storage conditions.
