✦ Synopsis

Abstract

A simple and rapid method using headspace liquid‐phase microextraction (HS‐LPME) was developed for the determination of hexanal at low levels in potato crisp samples. Parameters such as extraction solvent, agitation of the sample, salt addition, organic drop volume, exposure time, and extraction time were controlled and optimised. The developed protocol was found to yield a linear calibration curve in the concentration range from 0.001 to 2 mg/L and a limit of detection of 0.1 μg/L with a good enrichment factor of > 107 for the analyte. The repeatability of the method was satisfactory (4%). The results demonstrate that HS‐LPME is a rapid, accurate, and effective preparation method and could be successfully used for the determination of hexanal in potato crisp samples.
