Low oil emulsion gel stabilized by defatted Antarctic krill (Euphausia superba) protein using high-intensity ultrasound

Effect of high-intensity ultrasound on the physicochemical properties, microstructure, and stability of soy protein isolate-pectin emulsion

“…ζ-potential can characterize the degree of electrostatic attraction or repulsion between adjacent particles in an emulsion system, and it is also a key indicator of emulsion stability. Compared with the untreated emulsion, the absolute value of the ζ-potential increased significantly after HIU treatment, and reached the maximum at 450 W. The increase in the absolute value of the ζ-potential would enhance the electrostatic repulsion between protein and inhibit aggregation, thereby promoting emulsion stability [27] . This was also one of the reasons for the improved emulsifying properties.…”

Effect of high intensity ultrasound on the structure and solubility of soy protein isolate-pectin complex

“…However, the absolute potential value decreased when the HIU was performed with higher power (600 W). Hu et al [43] believed that this phenomenon could be due to the formation of protein aggregates, which masked the polar sites on the protein surface. This is consistent with the results of this study.…”

Production of Sacha Inchi oil emulsions by high‐shear and high‐intensity ultrasound emulsification: Physical properties and stability

“…Probably, the oil droplets become more ordered along the flow field as the shear rate increases, offering less resistance to flow (Erçelebi & Ibanoğlu, 2009). Besides, during the high-shear process, the oil droplet clusters may suffer disintegration, and the shear-thinning behavior could be related to the non-Newtonian behavior of the continuous phase (Hu et al, 2021).…”

“…Ultrasoundassisted emulsification has been recently investigated, because stable emulsions with narrow particle size distributions in the micro or submicrometer range are produced by the cavitation phenomena caused by the acoustic fields (Meirelles et al, 2020). Moreover, ultrasound attracts attention for preparing emulsions because of its ease of operation, high energy efficiency, cost-saving, and ecofriendliness (Hu et al, 2021). Studies aiming to apply ultrasound emulsification to encapsulate, solubilize, and incorporate bioactive compounds in aqueous matrices have been reported (Lago et al, 2019;Meirelles et al, 2020).…”
