Ultrasound emulsification energy strategies impact the encapsulation efficiency of essential oils in colloidal systems

Ultrasound-Assisted Extraction and the Encapsulation of Bioactive Components for Food Applications

“…The encapsulation efficiency and emulsion kinetic stability was assessed through an acoustic power and process time binomial approach, and it was found that emulsions had kinetic stability even after 72 h of storage except for orange oil nanoemulsions and high encapsulation efficiency. Thus, it was concluded that HIUS has the capability to produce stable emulsions for further use in various matrices [163]. Ultrasonic-assisted eucalyptus oil nanoemulsion was performed by using response surface methodology wherein the optimal sonication parameters were standardized.…”

Novel naturally derived encapsulation agents in the ionic liquid form for sustainable emulsion-based products

“…Therefore, ILs performed as promising encapsulating agents at low concentration affording high EE values which are quite competitive when compared to those observed using traditional commercial additives, such as gum acacia, chemically modified starches (e.g., snow-flake, Hi-cap), among others 20 . Previously, rosemary EO emulsions obtained by HIU using gum Arabic as encapsulation agent at 10% (w/w) presented EE of eucalyptol from 83% to 97%, depending on the ultrasound energy strategy 21 . Moreover, soy lecithin and hydrolyzed whey protein have been shown to be as alternatives to polysaccharides 22 .…”

“…In fact, affording NEO-based emulsions with high kinetic stability with some traditional commercial encapsulating agents could be a challenge, and bioactive compounds are better retained in highly stable emulsions. In these cases, higher concentration of some commercial encapsulating agents can be used to achieve the desire performance 20,21 , unlike the proposed ILs used at 1% (w/w) with possibility of being used at much lower concentrations. To understand the similarity in EE of ILs, we investigated the emulsifying properties of ILs by emulsion characterization.…”
