“…According to Cunha et al. (2019), the oils that has PUFA/SFA ratio lower than 0.45 should be not used for human food due to potential risk for increase of cholesterol in blood. Therefore, oils obtained by performed extraction methods could be considered as suitable for human consumption.…”

Fruit processing by-product, raspberry (Rubus idaeus L.) seeds were utilized to obtain health beneficial oils. Cold pressing (CP) and supercritical CO 2 extraction (SFE) were applied to separate oil from seeds. Raspberry seed oils were analyzed in terms of fatty acids (FA) content, tocopherols, and functional quality indices. The residues after extractions were analyzed in terms of free and total ellagic acid content (TEAC). CP provided higher extraction yield than the SFE method. Oils isolated by both methods have a significant amount of ω-3 FA, even though oil obtained by SFE had slightly higher ω-3 FA content. Furthermore, oils obtained with both extraction methods exhibited high values of tocopherol content. In terms of ellagic acid content, residues after SFE had higher values of free and TEAC than residues after CP. Practical applications Raspberry seeds are currently underutilized by-product of the fruit processing industry. These seeds could be further processed to obtain oil with high quantity of essential ω-3 fatty acid and polyphenol extracts with high content of ellagic acid. Isolated oil and phenolic extracts could be used in various food, cosmetic, and nutraceutical products to increase its nutritive composition and functional properties. Utilization of cold pressing (conventional extraction technique) and supercritical CO 2 extraction (novel and green extraction technique) for oil recovery in the same study enables a direct comparison of these techniques and reveals the advantages and disadvantages of supercritical CO 2 extraction for potential industrial application.

The aim of this study was to valorize the oil recovery from red and white grape seeds (Vitis vinifera L.) that remains as by-product after the winemaking process. Oils were extracted by modern techniques, ultrasound assisted (UAE), microwave assisted (MAE) and supercritical fluid extraction (SFE), and compared to the Soxhlet extraction (SE). Firstly, SFE was optimized at different operating conditions: pressure (250–350 bar), temperature (40–60 °C), CO2 flow rate (0.2, 0.3 and 0.4 kg h−1), and particle size (315–800 µm and >800 µm). The highest extraction yields were achieved by SFE at the optimal conditions: 350 bar, 60 °C, 0.4 kg h−1. Afterwards, SFE was compared to SE, UAE and MAE with respect to oil extraction yields, and analyzed for fatty acid composition and antioxidant capacity. Considering the general classification of fatty acids, it was found that samples had high content of polyunsaturated fatty acids, regardless of extraction technology. Tocopherol content was significantly influenced by all extraction methods, whereas UAE and MAE resulted in extracts richer with lipophilic antioxidants. In conclusion, modern extractions that are suited for industrial applications had better performance as compared to SE, as judging by the oil yield and quality.
