Ultrasonic treatment on physicochemical properties of water-soluble protein from Moringa oleifera seed

Recent innovations of ultrasound green technology in herbal phytochemistry: A review

“…Ultrasound treatment affects the protein structure in herbs due to its modifying effect on some secondary bonds of β-sheets and β-turns, which affects the protein's hydrophilic groups and the hydrophobic core [ 91 ]. A study on arrowhead ( Sagittaria sagittifolia ) herbal protein showed that US treatment (28–40 kHz, 30–50 °C) caused unfolding of the protein structure, decreased α-helix and β-turn contents, and increased β-sheet and random coil contents.…”

Effect of ultrasonic pretreatment on eliminating cyanogenic glycosides and hydrogen cyanide in cassava

“…Hou et al [37] reported that ultrasonic treatment resulted in a decrease in the fluorescence emission value of chitinase. Both the increased and decrease intrinsic fluorescence intensity of water-soluble protein when treated with the increasing ultrasonic power (0–650 W) were found by Tang et al [39] . There was a relative difference of the changes of the intrinsic fluorescence intensity after sonication.…”

“…There was a relative difference of the changes of the intrinsic fluorescence intensity after sonication. The reason was possibly related to the different structure of the protein, in which the chromophoric groups exposed in a different way [39] . But all those results reflected the increase of enzymatic activity was induced by the stretch of the protein molecular.…”

“…The characteristic peak at 1648 and 1654 cm −1 from FTIR spectra was identified as amide Ⅰ band of the untreated and sonication samples, respectively. The increased wavenumber of amide Ⅰ band indicated the hydrogen bond was reduced after sonication [39] . The reason was likely involved in the disruption of hydrogen network by ultrasonic shearing force [38] .…”

High-power Terahertz Waves for a Recycle System of Amyloid Fibrils

“…Regarding the physical stimulation methods, external electric and magnetic fields 28 , microwaves 29,30 , and ultrasonication 31,32 have been investigated for the specific modification of proteins. Nonetheless, these approaches have merits and demerits in terms of versatility, conveniences, and economical aspects, and more efficient approaches will be desired for the construction of sustainable recycle system of the persistent biomaterials.…”
