Principles of electrospraying: A new approach in protection of bioactive compounds in foods

Abstract

Electrospraying is a potential answer to the demands of nanoparticle fabrication such as scalability, reproducibility, and effective encapsulation in food nanotechnology. Electrospraying (and the related process of electrospinning) both show promise as a novel delivery vehicle for supplementary food compounds since the process can be carried out from an aqueous solution, at room temperature and without coagulation chemistry to produce matrices or particulates in the micro- and nano-range. The presentation of core materials at the nanoscale improves target ability to specific areas of the digestive tract and gives improved control of release rate. Adoption of these electrohydrodynamic atomization technologies will allow the industry to develop a wide range of novel high added value functional foods. To optimize production conditions and maximize throughput, a clear understanding of the mechanism of electrospraying is essential. This article presents a comprehensive review of the principles of electrospraying to produce nanoparticles suitable for food technology application, particularly for use in encapsulation and as nanocarriers.

Electrospun curcumin-loaded protein nanofiber mats as active/bioactive coatings for food packaging applications

“…include the feasibility of obtaining dry, food-grade, nanostructured materials in a one-step process at mild temperature conditions (suitable for labile ingredients) with high encapsulation efficiencies. Moreover, by changing the solution properties and process parameters, the morphology of the obtained materials can be varied (Alehosseini et al, 2017;Echegoyen et al, 2017;Kriegel, Arrechi, Kit, McClements, & Weiss, 2008), allowing, for instance, the production of continuous layers in the form of fiber mats. Electrospun nanofibers present particular benefits for the production of food packaging coatings, such as higher crack resistance as compared to conventional films, absence of negative impact in the flexibility and mechanical properties of the packaging material to be coated and their good adhesion properties due to their large surface to volume ratio (Fabra, Busolo, Lopez-Rubio, & Lagaron, 2013).…”

“…It is a simple, efficient, versatile, cost-effective and scalable technology to produce dry nano-and microencapsulation structures in the form of fiber mats (electrospinning) or particulate powders (electrospraying), by subjecting a polymeric fluid to an external high-voltage electric field (Bhushani & Anandharamakrishnan, 2014;Echegoyen, Fabra, Castro-Mayorga, Cherpinski, & Lagaron, 2017). Due to its great potential, a number of review papers about the electrohydrodynamic processing technology (Bhattacharjee & Rutledge, 2017;Xie, Jiang, Davoodi, Srinivasan, & Wang, 2015;Zong et al, 2018) and its specific applications in the food sector (Alehosseini, Ghorani, Sarabi-Jamab, & Tucker, 2017;Bhushani et al, 2014;Echegoyen et al, 2017;Mendes, Stephansen, & Chronakis, 2017) have been very recently published, to which the readers are directed for further information about its basic principles and functioning.…”

Development and Characterization of Electrospun Nanostructures Using Polyethylene Oxide: Potential Means for Incorporation of Bioactive Compounds

“…Electrospinning is a method that was developed in the early 20th century, and it is known to be a versatile and economical fiber formation technique that is suitable for the production of In this sense, electrospinning can be considered an excellent technique for the formation of bioactive compounds carriers since the process occurs in a closed working system, which allows for a faster, secure and efficient production. Most of all, the procedure does not require specific solutions and can be executed under ambient temperature [2]. Although the electrospinning technique has already been applied to obtain nanostructures using PEO as the basis [22][23][24][25], none of the consulted manuscripts have simultaneously evaluated the main parameters of the electrospinning process.…”

Preparation and Characterization of Quercetin‐Loaded Zein Nanoparticles by Electrospraying and Study of In Vitro Bioavailability

“…Then, the liquid entering in the needle forms a cone ending in a jet through its apex. Finally, the highly charged liquid droplets disperse radially on the collector plate, due to Coulomb's repulsion of charges (Alehosseini, Ghorani, Sarabi-Jamab, & Tucker, 2017;Jayaraman et al, 2015). The parameters that exert an influence on the control of particle size are equipment parameters (applied voltage, flow rate, and distance of the collector), parameters of the polymer solution (concentration, viscosity, density, conductivity, and surface tension), and environmental parameters (humidity and temperature; Jaworek, Sobczyk, & Krupa, 2018;Tapia-Hernández, Rodríguez-Félix, & Katouzian, 2017).…”
