Various techniques were used to extract flaxseed oil, where the quantity and quality of flaxseed oil were measured. Solvent extraction gave the highest oil yield. Oil extracted by SCE showed the best quality in terms of unsaturation and antioxidant activity.
How do you extract oil from seeds?
The two most common processes to extract oil for most seeds, beans, and nuts is the Full Press Extraction Process where mechanical screw presses are used to extract the oil by squeezing the oil under high pressure, and the Preparation/Solvent Extraction Process where a solvent is mixed with the material to separate the oil.
How is flaxseed extracted?
One gram of ground flaxseed was added in the extrac-tion column (5 mL). Spe-ed wool was added to both ends of column and the column was closed. The filled column was then placed in an oven where temperature was controlled throughout the extraction process.
How much oil is extracted from ground flaxseed?
Moisture content of ground flaxseed was found to be 6%, whilst that of oil after 13 h of Soxhlet extraction was 41.53 ± 1.01% ( w / w) oil. This was considered as the amount of total oil. Further oil yields are stated in terms of percentage extraction based on this value of total oil.
