  • How span 20 is used to demulsify walnut oil?
  • Demulsification mechanism using Span 20 at acidic pH during SAAE was discovered. Highest walnut oil yield (90.74%) was obtained at sugar solution of 1 mol/L, solvent-to-sample ratio of 4:1, and extraction temperature of 85 °C, extraction time of 60 min, 1.9 g/100 g Span 20, and pH 6.0.
  • How does span 20 affect extraction yield?
  • However, the effect of Span 20 on extraction yield illustrate a key difference in extraction mechanisms ( Fig. 4 d), effectively destabilizing the emulsion formed and increasing yield from 60.56% to 90.74% during extraction of walnut. Span 20 possesses lower molecular mass and diffuses rapidly to the interface than protein.
  • Does span 20 destabilize the emulsion?
  • The oil yields of AEP, SAAE and SSAE were 44.7%, 55.3% and 91.2%, respectively. This difference further validated the fact that Span 20 could effectively destabilize the emulsion and improve oil recovery during extraction of walnut. Fig. 5.
  • Does span 20 increase oil yield?
  • The obtained high oil yield of Span 20 was mainly attributed to its stronger adsorption than protein at the interface and slight oil solubility at acidic pH. Span 20 significantly improved oil yield by allowing the release of oil and decreasing the emulsion fraction, without evident change in the walnut protein.
