This study aimed to investigate the volatile organic compounds (VOCs) variations during the spoilage of palm wine stored at ambient temperature and identify potential shelf-life markers. Palm wine collected from local tappers and resellers were stored at ambient temperature (28-30°C) for 96 h. At an interval of 24 h, VOCs variations were investigated using Solid phase Microextraction-Gas Chromatography-Mass Spectroscopy (SPME-GC/MS) method. Changes in sensory quality and potential flavour contributors were also explored. The sensory rejection time was found at 24 h and 48 h of storage for palm wines collected from the tappers and resellers, respectively. The first attribute to be spoiled was taste followed by odour and appearance. A total of 23 VOCs distributed in six chemical families were identified. Alteration of palm wine sample is characterised by an increase in concentration of alcohol (isoamyl alcohol, isobutanol and 1-octanol), aceti acid and acetoin, and a decrease in ester concentration (ethyl acetate and ethyl hexanoate). In the view to fight against the short shelf-life and develop new preservation methods, these compounds can be used as markers of spoiled palm wine. |
