Mutagenicity of alcoholic beverages

Area of Science:

• Toxicology
• Food Safety
• Genetics

Background:

• Alcoholic beverages are widely consumed globally.
• Potential health risks associated with alcoholic beverage consumption require thorough investigation.
• Understanding the mutagenic properties of these beverages is crucial for public health.

Purpose of the Study:

• To assess the mutagenicity of various alcoholic beverages, specifically whisky and brandy.
• To identify the presence and characteristics of mutagenic compounds in these beverages.
• To evaluate the influence of metabolic activation (S9 mix) on the observed mutagenicity.

Main Methods:

• Utilized the Ames test, a standard bacterial reverse mutation assay.
• Employed Salmonella typhimurium strains TA100 and TA98 with a pre-incubation modification.
• Tested evaporated residues of alcoholic beverages, with and without the addition of S9 mix.

Main Results:

• Mutagenic activity was detected in 12 out of 13 whisky brands tested against Salmonella typhimurium TA100.
• The mutagenicity of whisky was significantly reduced or abolished upon addition of the S9 mix.
• Brandy and apple brandy samples exhibited similar mutagenic profiles to whisky.

Conclusions:

• Evaporated residues of whisky and brandy possess mutagenic potential.
• The mutagenic compounds in these beverages appear to be non-metabolically activated.
• Further research is warranted to isolate and identify the specific mutagens present in alcoholic beverages.
