Almond oil extraction using supercritical fluids (CO2) & pressing (both hydraulic & screw press) provides a product that is fit for human consumption with the pleasant sensorial characteristics that belong the primary product (the almond), consequently, no refining is needed, making the product a virgin oil.
How do you make almond oil?
The oil is obtained generally through a cold-pressing process; however, sweet almonds can be pressed warmly. First, the almonds clean of impurities & loosed from their shells. The pre-cleaned seed is then lightly warmed to the press temperature and subsequently fed into a screw press.
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.
How are almond oil yields formed?
Almond oil yields were formed with asymptotic values at large extraction times that were close to the values obtained by Soxhlet extraction. An extraction model based on the physical evidence of broken & intact oil cells has been developed. It accounts for a former equilibrium regime & a latter finite mass transfer regime.
