Analysis of oxidative stability and fatty acids profile of coconut oil and flaxseed oil blends
This study aimed to analyze the oxidative stability of flaxseed oil and coconut oil blends. Coconut oil: flaxseed oil was mixed at different ratios on weight basis (95:5, 90:10, 85:15, 80:20, and 75:25). The oxidative stability was measured using acid value, iodine value, peroxide value, and saponi...

| Summary: | This study aimed to analyze the oxidative stability of flaxseed oil and coconut oil blends. Coconut oil: flaxseed oil was mixed at different ratios on weight basis (95:5, 90:10, 85:15, 80:20, and 75:25). The oxidative stability was measured using acid value, iodine value, peroxide value, and saponification value under accelerated oven storage and frying conditions. The fatty acid profile was determined by gas-liquid chromatography. According to the results, all blends showed acceptable oxidative stability under both conditions. They showed storage stability up to 14 months under ambient conditions. Blended oils had a more balanced SFA: MUFA: PUFA ratio than the original oils. Blending the oils at the ratio of 80:20 (coconut oil: flaxseed oil) showed the desirable omega-3 and omega-6 fatty acid composition before and after frying. Therefore, the blending of flaxseed oil with coconut oil could widen the applicability of flaxseed oil.
