Abstract

The invention relates to a method for detecting exogenously added ethyl caproate in liquor based on stable isotope technology and principles, and belongs to the technical field of authenticity identification of liquor. The main steps are as follows: (1) measure the carbon isotope composition of the target compound (ethyl hexanoate) in a real liquor sample of a certain flavor, measure the carbon isotope composition of the carbon isotope endogenous marker of the target compound, and determine the target compound and The average difference and standard deviation (σ) of the δ13C values ​​between the internal standards; (2) measure the δ13C values ​​of the target compound and its endogenous markers in the liquor samples to be tested, and calculate the difference between the two Δ13C samples to be tested; ( 3) Determine whether the sample to be tested contains ethyl hexanoate added from an external source. The invention utilizes the stable isotope technology to establish a method capable of accurately detecting whether the liquor contains ethyl hexanoate added from an external source.
