Almond oil is a kind of functional edible oil with rich nutrition and high medicinal value. This paper reviews the various functional properties of almond oil such as antioxidation, hypoglycemic effect and cardiovascular disease prevention, as well as the extraction and microencapsulation technology at home and abroad. The benefits and drawbacks of all these technical methods are made clear by comparing various extraction techniques, such as mechanical expression, solvent extraction, and water extraction of almond oil, as well as microencapsulation techniques, such as spray drying, complex coacervation, extrusion, and freeze-drying. The study provides a feasible, quick, effective, and secure technology for the industrial production and preparation of almond oil and might serve as a theoretical reference for its stable preparation and rational utilization.
