Unveiling the mechanism of ultrasound-assisted phenolic extraction from Psidium cattleianum leaves: Kinetic, mass transfer, and thermodynamic insights.

ABSTRACT: Strawberry guava leaves (Psidium cattleianum) are an attractive phenolic-rich byproduct for food and pharmaceutical production, with potential benefits for human health due to their exceptional antioxidant activity among plant-based resources. However, there are no systematic studies on sonochemical phenolic extraction from this material. Therefore, the goal of this study was to unveil the mechanism of ultrasound-assisted extraction (UAE) for phenolic recovery from Psidium cattleianum leaves. Pseudo-second-order kinetic modeling, Biot number, and thermodynamic analysis were introduced to describe the extraction mechanisms and then kinetic parameters such as saturation concentration (C_s), extraction rate (k), diffusion coefficient (D_eff), and mass transfer coefficient
