Extraction Methods of Oils and Phytochemicals from Seeds and

Expeller pressing and organic solvent extractions are common methods for oil extraction in the food industry. However, these two methods come with some concerns, such as lower yields for expeller pressing and environmental concerns for organic solvents.

The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several ...

Recent advances in green soybean oil extraction

According to USDA [1], the production of soybeans worldwide in 2020/2021 was about 360,000 thousand metric tons. The soybean seeds are mainly destined for protein, edible oil, and biodiesel production. The main components of the seeds are proteins (40 wt%), lipids (20 wt%), carbohydrates (15 wt%), and ashes (5 wt%).

Oil extraction is one of the most critical steps in seed oil processing because it determines the quality and quantity of oil extracted. Optimization of the extraction conditions for each extraction method enhances yield and quality meanwhile a carefully chosen optimization process equally has the potential of saving time and heat requirements ...

Enzymatic processes provide opportunities and alternative approaches to traditional methods. This article reviews various enzymatic processes that are currently adapted by the industry at commercial scale and ongoing research and development efforts in the field.

Soybean Oil Extraction and Processing

Abstract. Soybeans are the dominant oilseed in both U.S. and world markets. During a typical year soybean production comprises over half the worldwide oilseed production ( Anonymous 1995 ). However, according to Dutton (1981) in the early 1940s, soybean oil was considered a poor quality oil, not suitable for food use, and more appropriate for ...

Oilseed processing and oil extraction processes are designed to obtain high quality oil with minimal undesirable components, achieve high extraction yields and produce high value meal. There are several techniques for extracting oil from oilseeds. Two common oilseed extraction processes are solvent extraction and mechanical extraction using a ...

Their Environmental and Economic Impacts

Historically, oil has been pressed out of seeds by indigenous communities for centuries, and the mechanical pressing of soybeans dates back to the 1940s [14]. There are two broad categories of equipment for oil extraction: expeller press and extruder (Figure2). Expeller pressing is often limited to small scale, on-farm seed grinding operations.

Edible oil extraction is a large and well-developed sector based on solvent assisted extraction using volatile organic compounds such as hexane. The extraction of oil from oilseeds generates large volumes of oilseed by-products rich in proteins, fibres, minerals and secondary metabolites that can be valued. This work reviews the current status and the bio-macro-composition of oilseeds, namely ...
