“…The fish oil encapsulated into the zein fibers showed higher oxidative stability than the unprotected oil at different storage conditions. Yang et al encapsulated fish oil into zein-polyvinylpyrrolidone fibers by coaxial electrospinning, obtaining a fiber medium diameter of 560 nm, a loading capacity of 14.5% and an encapsulation efficiency of 97% [20]. García-Moreno et al used the emulsion electrospinning process to encapsulate cod liver oil into zein, pullulan and poly(vinyl) alcohol (PVA) fibers [21][22][23].…”

Long chain polyunsaturated omega-3 fatty acids (PUFAs), namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are important functional ingredients due to their well-documented health benefits, but highly susceptible to oxidation. One of the most promising approaches to preserve bioactives is their encapsulation within protective matrices. In this paper, an innovative high throughput encapsulation technique termed as emulsion electrospraying assisted by pressurized gas (EAPG) was used to encapsulate at room temperature nanodroplets of algae oil into two food hydrocolloids, whey protein concentrate and maltodextrin. Spherical encapsulating particles with sizes around 5 µm were obtained, where the oil was homogeneously distributed in nanometric cavities with sizes below 300 nm. Peroxide values under 5 meq/kg, demonstrated that the oil did not suffer from oxidation during the encapsulation process carried out at room temperature. An accelerated stability assay against oxidation under strong UV light was performed to check the protective capacity of the different encapsulating materials. While particles made from whey protein concentrate showed good oxidative stability, particles made from maltodextrin were more susceptible to secondary oxidation, as determined by a methodology put forward in this study based on ATR-FTIR spectroscopy. Further organoleptic testing performed with the encapsulates in a model food product, i.e., milk powder, suggested that the lowest organoleptic impact was seen for the encapsulates made from whey protein concentrate. The obtained results demonstrate the potential of the EAPG technology using whey protein concentrate as the encapsulating matrix, for the stabilization of sensitive bioactive compounds.

A porous hollow fiber membrane using polylactide (PLA), a representative bio‐derived polymer, was successfully fabricated. The use of high surface area fabrics can effectively absorb liquids, making it possible to impart selective absorbency to fabrics made of hydrophobic PLA. In this study, a porous PLA fabric was developed by applying the porosity of the fiber surface depending on the solvent, and the change was confirmed by morphological image analysis. To increase the total surface area effectively, hollow fibers were fabricated with coaxial electrospinning to maintain the pores of the surface while having a hollow space, and the changed oil absorption based on the fiber structure was measured. To enhance the selective absorption of the fabric to the oil, a coating process using nanoparticle was added. Dodecyltrichlorosilane‐treated silica became superhydrophobic by attaching special functional groups to the surface of the particles. The treated silica was coated on the surface of the fabric to provide the functionality. To confirm the selective absorbency of the coated fabric, changes in oil and water absorption were analyzed, and the performance of the fabric was demonstrated. The fabricated PLA porous hollow fiber membranes are expected to replace existing products in the fields of tissue engineering, biofilters, and environment‐friendly fabrics.

“…16,17 In the past few years, electrospinning has been well established for encapsulating bioactive compounds. [18][19][20] It can be even used to develop a colon-targeted delivery system to achieve slow and sustained release of protein. 21 In order to improve its stability and bioavailability, a novel colon-specic delivery system for SCT was developed by electrospinning in this study.…”
