Oxidative Stability of Blended Vegetable Oils
Summary
Oxidative stability refers to the resistance of oils to chemical degradation when exposed to heat, light or air. In blended vegetable oils, combining different lipid sources can enhance shelf life and nutritional quality by balancing fatty acid profiles and endogenous antioxidants such as tocopherols and phenolic compounds. The degree of unsaturation is a key determinant: highly unsaturated oils tend to oxidise more rapidly, whereas saturated or monounsaturated fractions confer greater thermal resilience. Blending strategies often aim to reduce reliance on palm oil or other high-saturated lipids for sustainability, while preserving desirable functional properties in frying, baking or salad dressings. Analytical methods such as peroxide value, p-anisidine value, induction period (Rancimat test) and radical scavenging assays (DPPH or ABTS) are routinely employed to monitor primary and secondary oxidation products. Recent advances have explored the synergy between minor bioactive lipids and natural extracts to delay rancidity, while optimising sensory attributes. The global trend towards healthier, cleaner-label foods has spurred interest in tailor-made oil blends that deliver both nutritional benefit and oxidative resilience under industrial processing and domestic storage conditions.

Technical terms
Oxidative stability: The measure of an oil’s resistance to oxidation under specified conditions.
Peroxide value: An indicator of primary oxidation products formed in fats and oils.
Induction period: The time until a rapid increase in oxidation markers, often determined by a Rancimat apparatus.
Radical scavenging activity: The capacity of a sample to neutralise free radicals, commonly assessed by DPPH or ABTS assays.
Tocopherols: Lipid-soluble antioxidants (vitamin E congeners) that inhibit propagation of lipid peroxidation.
