Polycyclic aromatic hydrocarbons in processed food: Formation, occurrence, analysis and reduction.

Area of Science:

• Food Chemistry
• Analytical Chemistry
• Toxicology

Background:

• Polycyclic Aromatic Hydrocarbons (PAHs) are carcinogenic contaminants formed during food processing and storage.
• Dietary intake is the primary route for human exposure to PAHs.
• Existing regulations for PAHs in processed foods have limitations, with some categories like alcoholic beverages not fully covered.

Purpose of the Study:

• To provide a comprehensive understanding of PAH formation and prevalence in processed foods.
• To detail analytical methods for accurate PAH identification and quantification.
• To explore effective strategies for reducing PAHs and enhancing food safety.

Main Methods:

• Review of formation pathways of PAHs during thermal processing and storage.
• Analysis of current analytical methodologies for PAH extraction, clean-up, and instrumental detection.
• Evaluation of existing and potential reduction strategies for PAHs in food.

Main Results:

• PAHs are significant contaminants in processed foods, primarily originating from thermal processing.
• Accurate analytical methods are critical for monitoring PAH levels in diverse food matrices.
• Dietary exposure to PAHs necessitates robust mitigation measures.

Conclusions:

• Understanding PAH formation and prevalence is key to managing food safety risks.
• Optimized analytical techniques are essential for reliable PAH quantification.
• Implementing reduction strategies is crucial to minimize human exposure to PAHs from processed foods.
