1.Raw material preparation: First, prepare the olive pomace raw material.
2.Ultrasonic assisted extraction: Add n-hexane to the olive pomace raw material, and use ultrasound assisted extraction to obtain olive pomace crude oil.
3.Deacidification: The olive pomace crude oil is subjected to waterless long mixed deacidification treatment to obtain deacidified olive pomace oil.
4.Dehydration: The deacidified olive pomace oil is dehydrated to obtain dehydrated olive pomace oil.
5.Decolorization: The dehydrated olive pomace oil is subjected to primary and secondary decolorization treatment to obtain secondary decolorized olive pomace oil.
6.Deodorization: The secondary decolorized olive pomace oil is deodorized to obtain finished olive pomace oil.
The principles and advantages of ultrasonic extraction:
Ultrasonic extraction is a mature extraction technology that uses the cavitation, mechanical and thermal effects of ultrasonic waves to accelerate the target components into the solvent and promote extraction. Ultrasound waves can produce strong cavitation, rupture plant cell walls, and release effective intracellular substances. In addition, the mechanical vibration and disturbance effects of ultrasonic waves can also significantly improve extraction efficiency.
The application effect of ultrasonic extraction in olive oil extraction:
The method of ultrasonic-assisted extraction of olive oil has the advantages of simple process, safety and environmental protection, high efficiency and rapidity, good oil quality, and high oil yield. It is especially suitable for the production of small batches of olive pomace oil. In addition, ultrasonic extraction can significantly improve the extraction efficiency, shorten the crushing time, and complete the rupture of plant cell walls and the entire organism in an instant.
