Acoustic and Ultrasonic Methods for Particle Characterisation have many advantages. They are generally non-invasive, can be non-contact, are safe and often are economic. However, it can be difficult to interpret data, and the expertise and commercial

Ultrasound and light-based measurements were used to monitor changes in agitated and quiescent solution characteristics such as particle size distribution during casein aggregation and redistribution in a model colloidal system. The precipitation of

Low power ( 1 kW m− 2) ultrasound methods are well-known to impact on fat crystallization and structuring, they have many drawbacks, causing off-flavours through product oxidation and a metallic taste probably associated with sonotrode wear. Furthe

Given the increasing pressures on the global food system to produce more from the planet’s diminishing resources, the need to produce food that is safe to consume and reflects the information declared on pack is becoming ever more difficult to achi

In this study, the relationship between microstructure, fracturing behaviour and sound upon breakage was evaluated for four cocoa butter alternatives. Sound emission plays an important role in the sensory perception of snap, a key attribute for many

Crystal nucleation in food colloids is considered in the light of recent developments in classical nucleation theory (CNT); it is shown that CNT remains a sound basis upon which to understand nucleation in colloids and in particular nucleation in lip

A new approach to the monitoring of granulation processes using passive acoustics together with precise control over the granulation process has highlighted the importance of particle-particle and particle-bowl collisions in acoustic emission. The re

Ultrasound spectrometry is one of very few methods that can size particles over the range 10 nm to 1 mm for optically opaque, undiluted materials. It has in-line, non-invasive capabilities which make it a serious contender for use in industrial proce
