    Spiced meat products like sausages and salami were analyzed for nitrosamines. While high levels were absent, many samples contained trace amounts, with levels remaining stable after storage.

    Area of Science:

    • Food Science
    • Analytical Chemistry
    • Toxicology

    Background:

    • Nitrate and nitrite are common food additives.
    • Volatile nitrosamines are potential carcinogens.
    • Meat products are a significant source of dietary exposure.

    Purpose of the Study:

    • To quantify nitrate, nitrite, and volatile nitrosamines in spiced meat products.
    • To identify specific nitrosamines present.
    • To assess the stability of nitrosamines under storage conditions.

    Main Methods:

    • Gas chromatography-mass spectrometry (GC-MS) for nitrosamine identification and quantification.
    • Analysis of 100 spiced meat product samples.
    • Storage stability tests at 4°C and -20°C.

    Main Results:

    • No samples contained high nitrosamine levels.
    • Traces of nitrosamines (2-50 µg/kg) were detected in many samples.
    • NDMA, NDEA, NPip, and NPy were identified; levels were stable after storage.

    Conclusions:

    • Spiced meat products may contain low levels of volatile nitrosamines.
    • Storage conditions did not significantly alter nitrosamine concentrations.
    • Further research on dietary exposure and health implications is warranted.
