Overview

Kinetic modeling reveals enhanced phenolic recovery in strawberry guava leaves via ultrasound-assisted extraction, indicating improved mass transfer dynamics.

Key Points

  • To unveil the mechanisms of ultrasound-assisted extraction for phenolic recovery from Psidium cattleianum leaves.
  • Utilized pseudo-second-order kinetic modeling for extraction analysis.
  • Conducted thermodynamic and mass transfer analyses to compare ultrasound-assisted extraction with conventional methods.
  • Measured parameters including saturation concentration, extraction rate, diffusion coefficient, and mass transfer coefficient.
  • Identified a biphasic extraction mechanism with rapid initial release followed by diffusion-controlled mass transfer.
  • Ultrasound-assisted extraction demonstrated superior performance in phenolic recovery compared to conventional shaking extraction.
  • The process was characterized as spontaneous and endothermic, with significant increases in kinetic parameters.
