Cooking mackerel increases heterocyclic amines (HCAs), particularly PhIP, MeIQx, and AalphaC. Ordinary muscle tissue forms more HCAs than skin, especially when well-done.

Area of Science:

  • Food Chemistry
  • Toxicology
  • Analytical Chemistry

Background:

  • Heterocyclic amines (HCAs) are compounds formed during the cooking of muscle protein.
  • HCAs are known mutagens and potential carcinogens, raising concerns about food safety.
  • Mackerel is a popular fish consumed globally, making its HCA content relevant to public health.

Purpose of the Study:

  • To investigate the formation of specific HCAs in pan-roasted mackerel.
  • To determine the influence of cooking degree and tissue type (muscle vs. skin) on HCA levels.
  • To quantify the contribution of different mackerel tissues to the overall HCA burden.

Main Methods:

  • Pan-roasting of mackerel at different degrees of doneness.
  • Quantification of HCAs, including PhIP, MeIQx, and AalphaC, using analytical techniques (e.g., HPLC, LC-MS/MS).

  • Comparison of HCA concentrations in ordinary muscle and skin tissues.

    • Main Results:

    • High levels of PhIP, MeIQx, and AalphaC were detected in pan-roasted mackerel.
    • Significantly higher concentrations of HCAs were found in well-done mackerel.
    • Ordinary muscle tissue exhibited substantially greater HCA formation (76.1%) compared to skin.

    Conclusions:

    • Cooking degree and tissue type significantly impact HCA formation in mackerel.
    • Ordinary muscle is a major contributor to the HCA content of cooked mackerel.
    • These findings are crucial for understanding dietary exposure to HCAs from fish consumption.
