Enzyme-assisted extraction of oil (soybean, rapeseed, corn

The oil extraction process assisted by enzymes is of two types: (1) aqueous extraction and (2) cold pressing. In the former process, to enhance the recovery of oil, the enzymatic action is required, which degrades the cell wall of the seeds and also causes breakage of protein-polysaccharide colloid leading to emulsion formation and low yield is ...

This study presents enzyme-assisted aqueous extraction (EAAE) method for oil extraction from soybean. Parameters for EAAE of oil with 1398 neutral protease were optimized through single-factor and orthogonal test. Soybean oil (yield, 80.2% w/ w) was achieved under following optimized conditions: enzyme (conc., 840 IU / g soybean; pH, 7.0); enzymatic hydrolysis (temp., 45°C; time, 1.5 h ...

Destabilization of the emulsion formed during the enzyme

Soybean oil extraction from soybean flour by a neutral metallo-endopeptidase enzyme-assisted aqueous extraction process, optimized for effectiveness in reducing oil content of the solid residue, yields a small fraction of the oil as free oil whereas most is emulsified in a cream layer.

Oil Flotation and Extraction. One milliliter of the reaction mixture of the enzymatically treated or untreated soybean paste was filled to 5 mL with water, mixed, and then centrifuged at 3000 rpm for 10 min. The oil extraction from the floating oil was quietly done by twice adding 2.5 mL of n-hexane. Quantification of Oil Content in Enzyme ...

Economic Feasibility of Soybean Oil Production by Enzyme

The solvent extraction method is a common extraction method for oilseeds with low oil content (less than 20%), such as soybean. This process is thought to be one of the most efficient in terms of extracting vegetable oil, as it leaves little residual oil in the cake or meal [7], [8].

Study on enzyme-assisted aqueous extraction of oil from soybean

Enzyme (Protizyme)-assisted aqueous extraction of peanut was carried out by Sharma [23] to get the oil recovery of about 90%, whereas Qian [24] used neutral protease to extract oil from soybean to ...

in achieving high oil extraction recovery from extruded flakes. Aqueous extraction of extruded full-fat soy flakes gave 68% re-covery of the total available oil without using enzymes. A 0.5% wt/wt protease treatment after flaking and extruding dehulled soy-beans increased oil extraction recovery to 88% of the total avail-able oil.

  • What are the applications of enzymatic methods in oil extraction?
  • Applications of enzymatic methods in oil extraction from oilseeds, crude oil refining, protein recovery from defatted meal, and enzymatic reactions for modification of the extracted oil to improve quality and functional and nutritional properties are assessed.
  • Why is enzyme selection important in aqueous enzymatic oil extraction?
  • Appropriate enzyme selection is the key to efficient aqueous enzymatic oil extraction. Suitability of an enzyme or enzyme mixture is governed by the chemical composition of the seeds.
  • Why are enzymes used in oil extraction?
  • Enzymes have been used as processing aids to break up very complex physical seed structure and oil/protein assemblies referred to as oleosomes and release oil for easy recovery 8, 9, 10, 11, 12, potentially reducing the amount of water needed for oil extraction as compared with the aqueous oil-extraction method.
  • What are the disadvantages of enzymatic oil extraction?
  • Major disadvantages of the enzymatic oil-extraction processes are the high cost of enzymes, limited enzyme recycling options, and residual wet meal/defatted seed material that needs to be dried for storage and further reuse.
  • Is enzyme-aided oil neutralization effective for high FFA-content oils?
  • However, the process is energy-intensive. Although enzyme-aided oil neutralization has been examined 21, 22 the process is still at research and development stage, not commercial yet. The latter process is beneficial for high FFA-content oils.
  • Is enzyme-aided oil refining a viable alternative technology?
  • Hence, enzyme-aided oil refining can be an alternative technology to enhance sustainability of the refining process. Degumming is the first step in crude oil refining.
