Soybean oil deacidification by liquid¨Cliquid extraction using
This alternative deacidification process by liquid¨Cliquid extraction uses ethanol, a generally recognized as safe (GRAS) solvent, which allows minimizing the losses of nutraceutical compounds present in the oil. In fact, this study provides data that can be used to design a renewable solvent©based soybean oil deacidification process.

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 use in

Perspectives for using green solvents in soybean oil extraction. Disregarding the information about reuse, recovery, and technical-economical, which has a considerable lack of literature, the replacement of hexane in the industrial processes with a green solvent seems to be the best alternative for soybean oil extraction.

As with soybean oil extraction, the economic feasibility of alternative green extraction methods for other seeds were demonstrated to be dependent on their co-products. The values of the co-products (rapeseed meal and molasses) compensated for the higher crushing costs resulting from ethanol extraction compared to the hexane extraction of rapeseed oil [ 37 ].

Mechanisms of Aqueous Extraction of Soybean Oil | Journal
Aqueous extraction processing (AEP) of soy is a promising green alternative to hexane extraction processing. To improve AEP oil yields, experiments were conducted to probe the mechanisms of oil release. Microscopy of extruded soy before and after extraction with and without protease indicated that unextracted oil is sequestered in an insoluble matrix of denatured protein and is released by
