Enhanced crystallisation kinetics of edible lipids through the action of a bifurcated streamer

Abstract

The type of environment generated by an ultrasonic source is shown to alter the crystallisation of an oil. In particular a bifurcated streamer, with its unusual dual cluster, is surprisingly efficient at accelerating crystallisation.

Probing the mechanisms of enhanced crystallisation of APS in the presence of ultrasound

“…However, further insight is possible. The bifurcated streamer (BiS) system which can be generated in these oil systems was shown 18 to be highly active in the acceleration of APS crystallisation, in excess of what would be expected on a power basis alone (compared to other clusters). The reasons for this are now, perhaps, more apparent.…”

“…The effective attenuation coefficient of the crystallising media (see ref. 18 for details) was calculated by fitting the hydrophone positive envelope to a second order model. Table 2 shows how the attenuation coefficient changes in response to the time at which HIU was applied to the sample.…”

“…The cluster characteristics have been detailed before and are generated at a set power level. 18 These clusters are denoted by f /N where f is the PLE frequency and N an integer value. 16 The OTS was positioned with respect to the PLE tip using micrometers and stages (Thor labs).…”
