[N-nitrosamines in beer and nonalcoholic beverages]

Area of Science:

• Food Chemistry
• Analytical Chemistry
• Toxicology

Context:

• N-nitrosamines are a group of carcinogenic compounds found in various food products.
• Assessing the presence of these contaminants is crucial for public health and food safety.
• Previous studies have identified N-nitrosamines in certain fermented beverages and processed foods.

Purpose:

• To quantify the levels of carcinogenic N-nitrosamines in beer, kvas, kvas wort, dried pear, and a beverage prepared from dried pear.
• To determine the safety of these commonly consumed products regarding N-nitrosamine contamination.
• To apply a sensitive fluorescence technique for accurate N-nitrosamine detection.

Summary:

• A fluorescence technique was employed to analyze N-nitrosamine content in beer, kvas, kvas wort, dried pear, and pear-based drinks.
• Results indicated that only a few beer varieties contained trace levels of N-nitrosamines.
• Kvas, kvas wort, dried pear, and the derived beverage samples were found to be entirely free from detectable N-nitrosamines.

Impact:

• Provides crucial data on the safety of popular beverages and fruit products concerning N-nitrosamine contamination.
• Highlights the importance of analytical methods like fluorescence spectroscopy in food safety monitoring.
• Suggests that kvas and pear-based products are safe alternatives regarding N-nitrosamine exposure.
