Compared Ageing of Oil from Curcubitea Pepo in Two Different Storage Conditions
並列摘要
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 30°C) 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.
