Some new technologies such as ultrasonic-assisted extraction, supercritical fluid extraction, subcritical fluid extraction, and salt-assisted aqueous extraction have emerged as the most promising extraction techniques that allow eco-friendly and effective recovery of almond oil.
Does extraction process change the quality of almond oil?
The performance of both methods, as well as the quality and composition characteristics of the almond oils obtained, both from the physical-chemical and organoleptic point of view, have been analyzed to determine the possible changes that occurred in the oil due to the extraction system.
How to produce high quality almond oil without refining?
4. Conclusions Both pressure extraction systems (hydraulic and screw) are a good technology to obtain high quality almond oils, with a low content of free fatty acids and peroxides, leading to the production of a virgin oil that can be consumed directly, without refining.
What is almond oil obtaining process?
Almond oil obtaining process is much related to the processes for obtaining other nut oils. The nut is harvested previously to the autumn rains start (August-September). After harvesting, the next step is de-hulling, consisting of the removal of the mesocarp that appears to adhere to the nut & has not been lost by falling from the tree.
