AOAC Method 972.10 Gas Chromatography for Liquor analysis

Analysis of Liquor

Introduction

Liquor analysis, a crucial aspect of quality control and flavor research in distilled spirits, focuses on accurately determining various volatile and non-volatile components in the liquor. This allows for quality assessment, safety assurance, authenticity verification, and flavor profile analysis. The main analytes include ethanol, higher alcohols (fusel oils, such as n-propanol, isobutanol, and isoamyl alcohol), esters (such as ethyl acetate and ethyl lactate), organic acids, aldehydes, and potentially trace amounts of harmful substances (such as methanol and plasticizers). Gas chromatography (GC) is the primary analytical instrument used. This analysis provides a scientific basis for optimizing production processes and regulating the market. Classic methods such as AOAC 972.10 represent established approaches for standardized quantitative analysis of specific components in such complex matrices.

Overview

This solution conforms to the AOAC Official Method 972.10 Alcohols (Higher) and Ethyl Acetate in Distilled Liquors: Alternative Gas Chromatographic Method. To quantitatively determine the concentrations of specific fusel oils (higher alcohols) and ethyl acetate in distilled spirits (whiskies, brandies, vodkas, gins, rums, etc.) using gas chromatography with an internal standard.
