Study: How Olive Oil Enhances Cheese Flavor
Olive oil and cheese create a dynamic pairing that goes beyond taste. Research shows that when combined, these two ingredients interact chemically and physically to alter flavor, texture, and preservation. Key findings include:
- Phenolic compounds in olive oil bind with cheese proteins, reducing oxidation and enriching flavor.
- Herb-infused olive oils, like rosemary or oregano, can extend cheese shelf life by reducing lipid oxidation by over 75%.
- Olive oil emulsions in cheese production improve moisture retention and enhance aroma through increased fat breakdown.
- Cheese stored in olive oil gains antioxidants, while the oil itself loses up to 93.5% of its phenolic content due to binding with cheese proteins.
Pairing tips: Use bold oils like Picual for aged cheeses and delicate oils for soft varieties. Herb-infused oils add extra flavor and preservation benefits. Proper storage at cool temperatures maintains quality.
This combination isn't just delicious - it transforms both ingredients, creating new sensory experiences and practical benefits.
How Olive Oil Transforms Cheese: Key Scientific Findings and Benefits
Research Findings on Olive Oil and Cheese Flavor
Olive Oil-Whey Emulsion in Cheddar Cheese
Research on Cheddar cheese has shown that substituting milk fat with olive oil emulsions can improve water-binding capacity and encourage lipolysis, a process that breaks down fats into free fatty acids, contributing to a richer cheese aroma. These emulsions hold more water than traditional milk fat, increasing moisture levels, which supports this breakdown. However, this substitution also results in lower total solids compared to full-fat Cheddar, which can influence the cheese's overall sensory qualities. These findings open up possibilities for further studies on how olive oil might impact cheese preservation and flavor.
Herb-Infused Olive Oils for Cheese Preservation
In Tunisia, researchers from the Laboratory of Olive Biotechnology examined how herb-infused olive oils could preserve and enhance fresh cheese. They used ultrasound-assisted extraction to infuse extra virgin olive oil with herbs like rosemary, oregano, basil, and thyme. Cheese stored in rosemary-infused oil for 21 days showed a dramatic reduction in TBARS values (a measure of lipid oxidation), dropping to just 0.53 mg MDA/kg compared to 2.98 mg MDA/kg in untreated cheese - a reduction of over 75%. The rosemary-infused oil also boasted a total phenolic content of 556.1 mg GAE/kg and an oxidative induction time of 82.25 hours.
Oregano-infused oils also stood out, with carvacrol making up more than 65% of the volatile fraction in treated cheese. Additionally, incorporating oregano essential oils boosted the cheese's antioxidant capacity by 43%.
"These results highlight the potential of bioactive-enriched olive oils as natural preservatives and functional ingredients, extending cheese shelf life while enhancing its nutritional value." - Hédia Manai-Djebali, Laboratory of Olive Biotechnology
This research emphasizes olive oil's ability to act as both a natural preservative and a flavor enhancer.
Low-Fat Gouda Cheese with Olive Oil Emulsion
A 2015 study explored a Gouda-style cheese made with an olive oil emulsion, finding that it had higher levels of free fatty acids, a sign of increased lipolysis and flavor development. However, when compared to full-fat versions, the latter still scored better in overall sensory evaluations.
The Science Behind Olive Oil and Cheese Pairing
Antioxidant Transfer and Phenolic Compounds
When olive oil meets cheese, phenolic compounds in the oil migrate to the cheese-oil interface. Here, they bind with casein proteins, forming polymers that not only enhance flavor but also create a protective shield against oxidation. This process helps prevent the development of rancid off-flavors during storage. Key players in this interaction are phenolic compounds like oleacein and oleocanthal, which are known for their antioxidant properties.
"Compositional changes in EVOO used as a medium for cheese preservation are under significant influence of the cheese's chemical composition." - Dora Klisović, Institute of Agriculture and Tourism
Interestingly, the strength of this binding depends on the type of cheese. Hard and semi-hard cheeses, which are rich in caseins, exhibit a much stronger affinity for these phenolic compounds compared to soft cheeses, which contain more whey proteins. Beyond preventing oxidation, these interactions also promote lipolysis, a process that enhances the aroma of the cheese.
Lipolysis and Aroma Development
Olive oil doesn’t just preserve cheese - it actively transforms it. Moisture from the cheese triggers hydrolytic degradation in the oil, breaking down triacylglycerols and releasing free fatty acids. These acids contribute to the complex aromas that make each cheese-oil pairing unique.
The moisture content of the cheese plays a big role in this process. For example, soft whey cheese, with a moisture content of about 74.4%, accelerates the release of free fatty acids more than harder cheeses. Over time, these fatty acids and other compounds migrate between the cheese and the olive oil, enriching both with new layers of flavor.
Phenolic compounds also influence how we perceive aroma. They interact with proline-rich proteins in saliva, forming complexes that can trap volatile compounds. Research from the University of Naples Federico II found that olive oils with high biophenol levels (around 511 mg/kg) can reduce the perceived "fruity" aroma by approximately 39%. This occurs due to the in-mouth interaction between phenols, saliva, and aroma compounds.
"The interaction between EVOO phenolics and proline-rich proteins could bind aroma compounds and consequently decrease their level during head-space analysis and during organoleptic assessment of olive oil." - Alessandro Genovese, Department of Agricultural Sciences, University of Naples Federico II
How Emulsions Affect Texture and Taste
When cheese and olive oil meet your palate, saliva creates a water-in-oil emulsion that changes how flavors and textures are experienced. This emulsion is dynamic, influenced by salivary proteins like mucins and albumin, as well as enzymes like lipase. These interactions affect the release of flavors and the overall mouthfeel.
The benefits of using olive oil as a ripening medium go beyond taste. A 2023 study from the University of Zagreb’s Department of Dairy Science found that semi-hard goat cheese ripened in a 50:50 blend of extra-virgin olive oil and refined sunflower oil retained a dry matter content of about 58.31%, compared to 62.96% in air-ripened samples. The oil-ripened cheese scored higher in sensory evaluations for texture and taste, as the oil prevented dehydration, which can make goat cheese less appealing.
"Oil as a ripening medium for cheese prevented water loss from the cheese... having a significantly positive effect on the sensory characteristics, particularly color, texture, and taste." - S. Levak, Department of Dairy Science, University of Zagreb
Ultimately, the viscosity and composition of the saliva-oil-cheese mixture influence how flavor compounds reach your olfactory receptors. This explains why the in-mouth (retronasal) perception of cheese paired with olive oil feels so different from the aroma you detect when simply smelling it. Pairing cheese with high-quality olive oil transforms the sensory experience, making every bite more complex and enjoyable.

For the best tasting experience, serve your olive oil at around 70°F (21°C) to fully release its aromatic volatiles. To maintain the quality of your cheese-and-oil pairings, store them in complete darkness at stable temperatures. This helps prevent oxidation and the development of rancid flavors. If you're sampling multiple pairings, cleanse your palate between tastes with slices of tart green apple and water.
Conclusion
Scientific studies reveal that olive oil can significantly alter cheese when the two are combined. When cheese is stored in extra virgin olive oil (EVOO), phenolic compounds from the oil transfer into the cheese, leading to an 85–93.5% reduction in the oil's phenolic content. This process enriches the cheese with antioxidants and creates new flavor profiles through interactions between proteins and phenols.
Fresh EVOO also contributes aromatic compounds - like (E)-2-hexenal - that add "green" and "fruity" notes. These aromas can brighten the richness of heavier cheeses, but only high-quality oils retain their potency. Additionally, rosemary-infused olive oil has been shown to significantly lower TBARS values, offering enhanced oxidative protection compared to untreated oils.
"EVOO could be used as an alternative to a less healthy fat, such as butter, without sacrificing overall flavor or flavor complexity of the dish."
- Jean‑Xavier Guinard, International Journal of Gastronomy and Food Science
These findings provide clear guidance for pairing practices. High-quality olive oils, like Big Horn Olive Oil's cold-pressed varieties with at least 350 mg/kg of phenolic content, are essential for preserving both antioxidants and key flavor compounds.
