“…The polynomic polymer solution of sodium alginate and soy protein isolate in aqueous solution containing a suitable divalent counter cation like Ca 2+ has the tendency to form hydrogel beads. Accomplishing smooth and more spherical microbeads can be obtained by enhancing the total solid content as earlier reported (Zaeim, Sarabi‐Jamab, Ghorani, Kadkhodaee, & Tromp, 2018). Size of the microbead is also affected by the viscosity of the hydrogel materials (Kruif & Tuinier, 2001; Maltais, Remondetto, & Subirade, 2008).…”

The present study was designed with the objective to compare the viability and stability of free and encapsulated probiotics under simulated technological and human gastrointestinal conditions. L. acidophilus was encapsulated using two wall materials (sodium alginate, soy protein isolate, and SA-SPI) by extrusion method for enhanced viability under stressed conditions. Free and encapsulated probiotics were subjected to some simulated technological and gastrointestinal conditions. Furthermore, free and encapsulated probiotics were also incorporated in dairy dessert to evaluate the viability and stability during storage. Encapsulation using sodium alginate and SPI as a coating materials significantly (p < .05) improved the survival of probiotics under simulated gastrointestinal and thermal conditions. The buffering effect of microbeads prolonged their survival and stability of under simulated conditions. The number of surviving probiotic cells encapsulated with sodium alginate, SPI, and SA-SPI over 120 days of product storage was 7.85 ± 0.39, 7.45 ± 0.37, and 8.50 ± 0.43 cfu/ml, respectively. In case of free cells, the surviving cells were just 3.5 ± 0.18 cfu/ml over the period of storage. In short, the study depicted that encapsulation provides protection during exposure to various hostile conditions.

“…The grooves on the surface of the beads could be attributed to incomplete evaporation of the solvent and unentanglement of biopolymer chains which made the unsolidified part liable to deformation when hitting the collector. 21 The polar monomers, which improved the conductivity and increased the entanglement of the molecules, eliminated some grooves on the beads. Thirdly, the average diameter of SBS/pitch decreased because more polar molecules were introduced when the grafting temperature was increased; hence the conductivity of the solution was increased and finally resulted in a stronger electric field force to draw thinner fibers out.…”

“…According to Wenzel and Cassie models, 21,22 the roughness and low surface energy of the solid surface would improve the hydrophobic performance of the solid. This is because the increase in graft reaction temperature affected the surface roughness, indicating that the contact angles were proportional to the graft reaction temperature.…”

To develop a fluorine-free material of acidproof and breathable fabric, styrene–butadiene–styrene (SBS) blended with pitch was directly deposited on polyester/cotton blended fabric through electrospinning to fabricate a nanofibrous membrane composite fabric. Acrylic acid (AA) and methyl methacrylate (MMA) were used to graft SBS to improve compatibility between SBS and pitch, and the modified temperatures were set at 40°C, 60°C and 80°C. The effects of different grafting monomers and temperatures on the properties of SBS/pitch membrane composite fabrics were explored by Fourier transform infrared spectral analysis; morphological structures, acid-resistant properties and breathability (vapor permeability and air permeability) were also examined. The results showed that modified SBS/pitch membrane composite fabrics possessed good acid resistance and modest breathability. SBS-g-MMA/pitch (means SBS grafted by MMA) exhibited the highest acid resistance due to more evenly distributed beads than original SBS/pitch membrane composite fabrics and higher roughness than SBS-g-AA/pitch (means SBS grafted by AA) membrane composite fabrics. By systematically changing the grafting temperature, SBS-g-MMA/pitch membrane composite fabrics for which SBS was grafted by MMA at 80°C presented appropriate air permeability (120.5 mm/s), modest water vapor transport rate (13,656.45 g/(m2·d)), good tensile strength (1203 N) and bursting strength (616 N), and the best acid resistance (143°); meanwhile the acid penetration level reached level 3, which was attributed to the low surface energy caused by the fused ring from the pitch and the rough surface caused by the micro-beads in the nanofibers. The obtained modified SBS/pitch membrane composite fabric could be potentially applied in acidproof fabrics.

“…Nonetheless, some of them have been successfully used to generate encapsulation structures through this technique too. That is the case of Alyssum homolocarpum seed gum [69] or gum arabic [70], whose electrosprayabilities were enhanced by adding non-ionic surfactants and modulating their solution properties by strategies such as autoclaving the biopolymer solutions or using different methods to prepare the emulsions.…”

The electrospraying technique, which consists of electrohydrodynamic atomization of polymeric fluids, can be used to generate dry nano- and microparticles by subjecting a polymer solution, suspension or melt to a high voltage (typically in the range of 7-20 kV) electric field. This potential can be exploited for developing nano- and microencapsulation structures under mild temperature conditions. Thus, it constitutes a promising alternative to conventional microencapsulation techniques for sensitive ingredients, like most plant-derived bioactive compounds, especially for their application in the food sector. Given the importance of plants as one of the major sources of dietary bioactive compounds, significant attention has been recently paid to research the encapsulation of phytochemicals through novel techniques such as electrospraying, aiming to provide new tools for the development of innovative functional food products and nutraceuticals. In this review, the latest advances in the application of electrospraying for nano- and microencapsulation of phytochemicals are discussed, with a focus on their potential use in the food sector.
