This paper aims to assess the viability of usingn novel oil extraction methods for Sea Buckthorn (Hippophae rhamnoides L.). Supercritical fluid extraction (SCFE) although extensively used for oil extraction in other countries, is not commercially used in Romania at the moment. Cost constraints, as well as the ease of us, more established methods such as solvent extraction and cold pressing have delayed the implementation of such technologies. Three oil sources were investigated: oils extracted from dry berries using SCFE and cold pressing, and oil extracted from draff (residues after juice extraction) using SCFE. The oils have been analyzed using a HPLC unit, and their carotenoid levels were compared. The results show a slight variation in the carotenoid composition in relation to the extraction methods. This suggests that the SCFE method is viable to be used for large scale Sea Buckthorn oil production.
