چکیده

14 Regulatory, safety, and environmental issues have prompted the development of aqueous 15 enzymatic extraction (AEE) for extracting components from oil-bearing materials. The 16 emulsion resulting from AEE requires de-emulsification to separate the oil; when enzymes 17 are used for this purpose, the method is known as aqueous enzymatic emulsion de18 emulsification (AEED). In general, enzyme assisted oil extraction is known to yield oil 19 having highly favourable characteristics. This review covers technological aspects of 20 enzyme assisted oil extraction, and explores the quality characteristics of the oils obtained, 21 focusing particularly on recent efforts undertaken to improve process economics by 22 recovering and reusing enzymes. 23 24

Methods Used for Extraction of Maize (zea Mays, L.) Germ Oil-a Review

Maize oil is high in polyunsaturated fat, which is a heart-healthy fat, and low in saturated fat. Extraction of oils from oilseeds is a key step for their commercialization. The extraction process has a direct effect on the quality and quantity of protein and oils obtained. Various methods like cold pressing, solvent, super-critical fluid and aqueous extractions are in practice for oilseed extr...

Green solvents and technologies for oil extraction from oilseeds

Oilseeds are crucial for the nutritional security of the global population. 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 solven...

(31)P NMR phospholipid profiling of soybean emulsion recovered from aqueous extraction.

The quantity and composition of phospholipids in full-fat soybean flour, flakes, and extruded flakes and in the cream fraction recovered after aqueous extraction (AEP) and enzyme-assisted aqueous extraction (EAEP) of these substrates were studied with (31)P NMR. Extruded flakes had significantly more phosphatidic acid (PA) than flakes and flour prior to aqueous extraction. The PA content of the...

Microwave Assisted Extraction of Olive Oil Pomace by Acidic Hexane

In this study, Microwave-Assisted Solvent Extraction (MASE) was used to recover oil residues from pomace olive using acidic hexane. Results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. For both radiation powers used (170 and 510W), the optimal extraction time and most interesting content of acetic acid in hexan...
