Assessing Vodka Authenticity and Origin in Vietnam's Market: An Analytical Approach Using FTIR and ICP-MS with...

Area of Science:

• Food Science
• Analytical Chemistry
• Spectroscopy

Background:

• Vodka is a major part of Vietnam's alcohol market, facing threats from illegal and adulterated products.
• Ensuring consumer health and brand integrity is crucial in the beverage industry.

Purpose of the Study:

• To analyze vodka samples using advanced techniques.
• To detect adulteration and ensure product authenticity.
• To protect consumers and maintain market integrity.

Main Methods:

• Fourier Transform Infrared Spectroscopy (FTIR) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) were used.
• 300 vodka samples from five brands in Hanoi were analyzed.
• Principal Component Analysis (PCA) was applied to the spectral and elemental data.

Main Results:

• Significant variations in elemental composition (sodium, magnesium) were observed across samples.
• FTIR and ICP-MS data, analyzed by PCA, effectively differentiated vodka samples based on chemical profiles.
• Distinct chemical signatures were identified, notably isolating Rocket Vodka.

Conclusions:

• Advanced analytical methods like FTIR and ICP-MS are vital for detecting beverage adulteration.
• The study provides a robust model for ensuring food safety and protecting brand reputation in the alcohol industry.
• Findings support enhanced regulatory enforcement and consumer protection in Vietnam's vodka market.
