Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Ultrasonic cavitation in microspace

Chemical Communications, 2004
Ultrasound was irradiated to a micro-1D and -2D space having a characteristic length of 200 microm, and the presence of cavitation was confirmed from video images, and the generation of OH radicals, which was quantitatively evaluated with fluorometry.

Ultrasonic Cavitation at Solid Surfaces

Advanced Materials, 2011
AbstractIn spite of the great potential of applying high‐intensity ultrasound, which enables high‐temperature and high‐pressure chemistry with a reactor near room temperature and ambient pressure, sonochemistry at solid surfaces is at a weak stage of understanding with regards to the development of new materials and composite nanostructures.

Cavitation dynamics and flow aggressiveness in ultrasonic cavitation erosion

International Journal of Mechanical Sciences, 2021
Abstract The mechanisms of cavitation erosion have been the subject of numerous studies, but the cavitation dynamics and flow aggressiveness thereby produced are less known. We develop a new numerical model to capture the cavity evolution and pressure pulsation, which are related to cavitation erosion.

Ultrasonic cavitation for disruption of microalgae

Bioresource Technology, 2015
Challenges with mid-stream fractionation steps in proposed microalgae biofuel pathways arise from the typically dilute cell density in growth media, micron scale cell sizes, and often durable cell walls. For microalgae to be a sustainable source of biofuels and co-products, efficient fractionation by some method will be necessary.

Ultrasonic cavitation to prepare ECM hydrogels

Acta Biomaterialia, 2020
Hydrogels composed of extracellular matrix (ECM) have been used as a substrate for 3D organoid culture, and in numerous preclinical and clinical applications to facilitate repair and reconstruction of a variety of tissues. However, these ECM hydrogel materials are fabricated using lengthy methods that have focused on enzymatic digestion of the ECM with

Cavitation produced by Ultrasonics

Proceedings of the Physical Society. Section B, 1950
The problem of cavitation produced by ultrasonic vibration is examined theoretically. Equations are developed which describe the motion of a gas-filled cavitation bubble in a liquid medium subjected to alternating pressure; the case of an empty cavity is also considered Information is obtained concerning the distribution of fluid pressures and ...

The effect of ultrasonic cavitation on protein antigenicity

The Journal of the Acoustical Society of America, 1976
The antigenicity and enzyme activity of dilute solutions of RNAse exposed to ultrasonic cavitation have been measured as a function of exposure time. The rate of decrease of antigenicity was one-eighth of the rate of enzyme activity loss.

Evidence for ultrasonically induced cavitation in vivo

Physics in Medicine & Biology, 1981
The possibility of stable bubbles being produced during ultrasonic irradiation of a guinea-pig hind limb, has been examined using a pulse echo ultrasonic imaging technique, that can visualise, within a cross-section of the limb, both moving and stationary bubbles of diameters down to 10 mu m (Beck et al. 1978).
