Traceability markers to the botanical origin in olive oils

Area of Science:

• Food Science and Technology
• Analytical Chemistry
• Agricultural Science

Background:

• The market introduction of high-quality monovarietal olive oils necessitates robust quality control measures.
• Ensuring the botanical origin of olive oil is crucial for preventing consumer fraud.
• Existing analytical and regulatory frameworks may be insufficient for new olive oil products.

Purpose of the Study:

• To review existing traceability studies for olive oils, with a focus on botanical origin.
• To identify and classify parameters that can serve as traceability markers for olive varieties.
• To assess the need for advanced analytical tools and regulations in olive oil quality control.

Main Methods:

• Comprehensive literature review of traceability studies published up to April 2009.
• Classification of discriminant parameters as either compositional or genetical markers.
• Analysis of the effectiveness of various markers in determining olive oil's botanical origin.

Main Results:

• Several parameters demonstrate discriminant power for tracing olive oil back to its botanical origin.
• Compositional markers (e.g., fatty acid profiles, volatile compounds) and genetical markers (e.g., DNA-based methods) are key.
• The identified markers are essential for verifying the authenticity of monovarietal olive oils.

Conclusions:

• Traceability of olive oil's botanical origin is achievable through various analytical markers.
• Continued development of powerful analytical tools is vital for accurate quality control and fraud prevention.
• New regulations are needed to support the market for high-quality monovarietal olive oils and protect consumers.
