In this paper the application of ultrasound was investigated as a method for improving mass transfer during the first stage of a process of osmosis combined with dehydration drying to obtain grapes reduced in high calorie ...

The objective of this work was to develop egg white (EW) nanoparticles by application of high intensity ultrasound (HIUS) at different solution pHs and treatment temperatures. At pH 7 HIUS without heating decreased the ...

A sample preparation method based on ultrasound assisted-extraction (UAE) of Ca, Mg and P from swine feed has been described. The experiment was performed to cover the variables influencing the sonication process and, the ...
