In Canada, the potato (Solanum tuberosum) is by far the most cultivated vegetable and plays a major nutritional role. However, during storage, the potato can easily undergo germination. In this study we have shown the inhibition potential of ethylene as an anti-germinative agent acting especially on phenols. In both varieties assayed (Yukon Gold and Russet Burbank) in this study, the ethylene treatment led to a decrease in total phenol concentration of about 20%. The analysis of potato extracts showed the decrease of specific phenol concentrations which was dependant on the time and temperature of extraction. Our hypothese that the transformation of phenols into phenolic ethyl ethers via possible radical mechanism were then formulated and confirmed by LC and LC/MS.
