This is QC FOOD's literature summary of research conducted and published by outside authors. It is not an independent certification, test or third-party endorsement of Chef Imperial.
A 2023 study of fried snack foods
Researchers Patil, Waghmare and Annapure compared palm olein and sunflower oil during frying of several Indian battered foods, including different pakora-style products. Across the reported tests, palm olein generally showed lower indicators of oxidative deterioration and a more stable fatty-acid profile than the tested sunflower oil. The conclusion applies to those tested oils and snack-frying conditions, not to all vegetable oils.
A 2025 comparison of five frying systems
Lužaić and colleagues studied palm olein, regular refined sunflower oil, sunflower oil with TBHQ, sunflower oil with rosemary extract, and high-oleic sunflower oil in French-fry trials. Palm olein and high-oleic sunflower both showed strong oxidative stability in this experiment. TBHQ improved regular sunflower oil, but high-oleic sunflower showed stronger resistance to oxidation than the antioxidant-fortified standard sunflower variants under the tested conditions.
What an oil name does not settle
Palm olein is not equivalent to every palm-based crystallized commercial formulation. High-oleic sunflower is not equivalent to regular sunflower oil. A smoke point, advertised additive or price tag cannot replace controlled performance data. Nutritional decisions must also account for fatty-acid composition, including saturated fat.
Practical takeaways for restaurants
Ask vendors for fatty-acid profiles, product data sheets and batch certificates. Compare oils with the same recipes, temperatures, filtration and discard criteria. Calculate the cost of fat used per kilogram of finished food and publish actual measurements rather than assumptions.
What these findings mean for Chef Imperial
These studies support general knowledge about tested oil types and antioxidants. Neither study tested Chef Imperial, so they do not independently prove that Chef Imperial outperforms competitors.
