The aim of this study was to investigate the oil pumkin seeds of Curcubitea pepo from Congo-
Brazzaville. The ageing of oil extracted from the seeds of the pumpkin Curcubitea pepo stored at two
temperatures (6 and 30ºC) was monitored during storage for 11 months by comparison of physical and chemical
characteristics correlated with spectroscopic data. Medium infrared spectroscopy confirmed saponification
index data. Ultraviolet absorption confirmed peroxide index data. Antioxidant behaviour was monitored by
fluorescence and the effect of ageing on the two major fatty acid families was analysed by a study of chemical
composition correlated with differential scanning calorimetry measurements. This study showed an overall
lengthening of the fatty acid carbon chains and allowed preferential storage conditions to be specified for this
oil.
Key words: Ageing, chemical composition, Curcubitea pepo, DSC, MIR spectroscopy, ,
