What are MOSH and MOAH in Olive Oil?
Understanding MOSH and MOAH in Olive Oil
In the world of culinary delights, extra virgin olive oil stands as a beacon of health and flavor. However, beneath its golden-green shimmer lies a complex chemical composition that merits closer examination. Among these compounds are MOSH (Mineral Oil Saturated Hydrocarbons) and MOAH (Mineral Oil Aromatic Hydrocarbons)—contaminants that have raised concerns among health-conscious consumers. Understanding these substances is crucial for anyone seeking to make informed choices about the olive oil they bring into their homes.
What Exactly Are MOSH and MOAH?
MOSH and MOAH represent two distinct categories of mineral oil hydrocarbons that can contaminate food products, including olive oil. MOSH consists of saturated hydrocarbons derived from mineral oils, while MOAH comprises aromatic hydrocarbons that contain at least one aromatic ring in their molecular structure. These compounds don't naturally occur in olives but rather find their way into olive oil through various contamination routes during production, processing, or packaging.
The presence of these contaminants has become a growing concern because studies suggest potential health implications, particularly regarding MOAH, which may exhibit carcinogenic and mutagenic properties. Meanwhile, MOSH can accumulate in human tissues over time, though the long-term health consequences remain under investigation.
Sources of MOSH and MOAH in Olive Oil
Contamination can occur at multiple stages throughout the olive oil production journey. Understanding these sources empowers consumers to select products with reduced contamination risk.
Harvesting and Processing Equipment
One of the primary sources of MOSH and MOAH contamination stems from the machinery used during harvest and processing. Lubricants, hydraulic fluids, and other petroleum-based products employed in agricultural equipment and oil extraction machinery can inadvertently transfer these contaminants to the olives or the extracted oil. Antiquated equipment or poorly maintained machinery presents a particularly high risk of contamination.
This is precisely where quality-focused producers make a significant difference. Those who prioritize cleanliness, regular maintenance, and proper protocols drastically reduce contamination risks.
The Superior Alternative: Early-Harvest Extra Virgin Olive Oil
When seeking olive oil with minimal contamination risks, early-harvest extra virgin olive oil stands as the premium choice. The early harvest technique involves collecting olives before they fully ripen, resulting in oil with exceptional purity and nutritional profile.
The Argilos Difference
Argilos Early-Harvest Extra Virgin Olive Oil exemplifies the pinnacle of purity and quality control in olive oil production. Sourced from the pristine slopes of Mount Pangaion in Kavala, Greece, this extraordinary oil represents generations of traditional knowledge combined with modern quality assurance practices.
What distinguishes Argilos from conventional olive oils is its meticulous production process. Olives are handpicked at optimal ripeness and cold-pressed within hours of harvest, minimizing the risk of contamination that can occur with extended storage or processing delays.
Each bottle of Argilos EVOO undergoes rigorous testing to ensure it meets the highest quality standards, including checks for contaminants like MOSH and MOAH. This commitment to purity preserves not only the oil's extraordinary flavor profile but also its health-promoting properties. The high polyphenol content in early-harvest oils like Argilos provides antioxidant benefits that may counteract some of the oxidative stress concerns associated with contaminants.

Health Implications of MOSH and MOAH Exposure
The potential health effects of MOSH and MOAH contamination warrant serious consideration for health-conscious consumers. Current research provides a framework for understanding these risks, though ongoing studies continue to refine our knowledge.
Current Scientific Understanding
The European Food Safety Authority (EFSA) has expressed concerns about both MOSH and MOAH, with particular emphasis on MOAH due to its potential genotoxic and carcinogenic properties. While MOSH compounds may bioaccumulate in human tissues, including the liver, spleen, and lymph nodes, the clinical significance of this accumulation remains under investigation.
MOAH compounds, containing aromatic structures similar to known carcinogens, present a more definitive concern. Regulatory bodies worldwide have emphasized the importance of minimizing exposure to these compounds, especially in frequently consumed foods like olive oil.

Ensuring Your Olive Oil Is Safe: Practical Guidelines
Empowering yourself with knowledge about selecting olive oil with minimal contamination risk can significantly reduce your exposure to MOSH and MOAH.
Selecting Quality Olive Oil
When choosing olive oil, consider these key factors that correlate with reduced contamination risk:
- Opt for single-estate olive oils where traceability is guaranteed
- Look for oils packaged in dark glass bottles rather than plastic containers
- Select producers who demonstrate transparency about their production methods
- Prioritize early-harvest varieties, which typically undergo more careful processing
- Check for quality certifications and testing documentation
Artisanal producers like Nostos Goods, who focus on small-batch production with meticulous attention to quality control, typically present lower contamination risks compared to mass-market alternatives.
Beyond MOSH and MOAH: Other Quality Indicators in Olive Oil
While minimizing MOSH and MOAH exposure is important, other quality factors also contribute to both the health benefits and culinary value of olive oil.
Polyphenol Content and Freshness
High-quality extra virgin olive oils contain abundant polyphenols—potent antioxidants that not only contribute to the oil's distinctive flavor profile but also provide numerous health benefits. Early-harvest oils like Argilos typically contain higher concentrations of these beneficial compounds.
Freshness represents another crucial factor. Olive oil begins to degrade from the moment it's pressed, with oxidation gradually diminishing both flavor and nutritional value. This degradation process can potentially increase susceptibility to contamination, making fresh oils preferable from both quality and safety perspectives.
