Technologies for extraction of oil from oilseeds and other
The traditional methods of oil extraction are exhaustive and have low efficacy, while conventional method of mechanical pressing is simple and involves low cost but considered as an inefficient method because of low oil recovery when compared with chemical extraction methods. Due to higher oil recovery and economic gains, chemical methods of

Edible vegetable oils from oil crops: Preparation, refining
Compared with traditional extraction methods, these novel methods have the advantages of a higher oil extraction rate, less extraction time and less solvent consumption. In addition, the refining process of oil is also continuously optimized to meet the requirements of consumers for higher levels of oil quality [19].

Methods of Extraction for Vegetable (Carrier) Oils
CO2 extracted oils are extracted using fluid carbon dioxide as the solvent. Carbon dioxide is converted to liquid using high pressure making it a safe and effective solvent that allows all the desirable active constituents of a plant to be collected without the risk of heat degradation. Once the extraction is complete, the pressure is released

Understanding Hexane Extraction of Vegetable Oils
The solvent extraction of vegetable oils like soybean oil dominates the oilseed industry as the most popular extraction method used around the world. Most large-scale solvent plants use hexane extraction to chemically separate oilseeds into liquid fat and solid protein¡ªpopular ingredients in the food industry and many other market sectors.

Solvent Extraction for Vegetable Oil Production: National
This industry comprises facilities that produce crude vegetable oil and meal products by removing oil from oilseeds through direct contact with an organic solvent. The extraction process is the same for all eight types of oilseeds subject to this rule (soybean, cottonseed, canola, corn germ, sunflower, safflower, peanuts, and flax).

Vegetable Oils and Animal Fats : Sources, Properties and Recovery
Vegetable oils are a group of fats extracted from the plant sources such as seeds, nuts, cereal grains and fruits (Hammond 2003 ). The use of vegetable oils has been practised by the Ancients thousands of years ago. They collect the oil exuded from the plant by slowly heating up the oily plant products.
