Area of Science:

  • Environmental Chemistry
  • Food Safety
  • Analytical Chemistry

Background:

  • Polycyclic aromatic hydrocarbons (PAHs) and polycyclic aromatic compounds (PACs) represent the largest class of known environmental carcinogens.
  • Food is a significant source of human exposure to PACs, necessitating accurate data for public health risk assessment and control.
  • Environmental contamination and food processing methods contribute to PAC presence in both raw and processed foods.

Purpose of the Study:

  • To provide a comprehensive overview of analytical methods for determining PAC content in foodstuffs.
  • To discuss the nature, classification, and occurrence of PAHs and PACs in various food matrices.
  • To review extraction, isolation, separation, identification, and quantification techniques for PACs in food.

Main Methods:

  • Review of existing literature on PAC analysis in food.
  • Consideration of PAH/PAC properties, including octanol:water partition coefficients, solubility, and bioaccumulation potential.
  • Examination of various extraction, isolation, and analytical methodologies (separation, identification, quantification).

Main Results:

  • PAHs and PACs are prevalent in foodstuffs due to environmental contamination and processing.
  • Understanding PAC properties is crucial for assessing their behavior and impact in food.
  • Diverse analytical techniques are employed for PAC determination, requiring careful selection based on food matrix and analytical goals.

Conclusions:

  • Accurate determination of PACs in food is essential for evaluating and managing public health risks.
  • This review consolidates knowledge on PAC occurrence and analytical methodologies in foodstuffs.
  • Further research and standardized methods are needed for robust PAC exposure assessment in the human diet.
