“…After orange, lime is known as the second-richest source of hesperidin (Gattuso et al, 2007;Esparza-Mart ınez et al, 2016), and in human body, no trace of toxicity is observed at hesperidin (50 mg) intake (Garg et al, 2001). Encapsulation is the process of entrapping the active agents in a covering material (Calvo et al, 2012), for the purpose of the active agent's protection against physicochemical changes during preparation and storage (Hani et al, 2016), accompanied by release of the active compounds in time and avoiding the bitter taste during consumption (Gonc ßalves et al, 2017). One of the most common methods of encapsulation of active compounds is through freeze-drying (Fang & Bhandari, 2010;Nedovic et al, 2011).…”

Summary Polyphenolic extract from lime waste and hesperidin were encapsulated to reduce the bitter taste of flavonoid glycosides, mitigate destruction of nutrients during heat process and increase the nutrition value of orange juice. The properties of polyphenolic extract of lime waste, encapsules, the physicochemical and the sensory factors of enriched orange juice during storage were measured. The value of yield of the process (Y) and encapsulation efficiency (EE) was obtained within the range of 85–90% and 59–71%, respectively. The particle size of samples was reported within the range of 27–41 μm. The physicochemical properties in treatments follow the same pattern when compared with the control sample in 60‐day storage. In the sensory assessment, encapsulated formulas were considered to have the best treatment. If the hesperidin was not encapsulated, 80% of it would have been destroyed during pasteurisation, while when encapsulated, only 18.8–33.18% of hesperidin was destroyed.

“…The low polymer concentration can have caused the formation of beads in electrospun nanofibers which is mainly due to surface tension dominance over viscoelastic forces, resulting in absence of chain entanglement between polymer molecules . In the case of PVA 19.5% with flow rate of 0.25 mL/h, nanofibers have shown a uniform morphology and no beads formation was observed mainly due to significant increase of jet chain entanglement resulting in viscoelastic force dominance over columbic repulsion . However, when the same concentration of PVA used with higher flow rates (0.5 mL/h) as shown in Figure (b) nanofibers partially coalesced and non‐individualized fibers were observed.…”

This study describes the preparation and characterization of nanofibers with poly(vinyl alcohol) (PVA) as the wall matrix to encapsulate montmorillonite (MMT) clay and intercalated MMT‐urea nanocomposite using an electrospinning technique. Nanofibers encapsulated with (1–5%, w/w) MMT clay were successfully produced and characterized in relation to morphological, spectroscopic, structural, surface, and thermal properties. The electrospinning conditions for voltage, flow‐rate, and emitter to collector distance were 20 kV, 0.5, and 0.25 mL/h, and 10 cm, respectively. The surface roughness increased from 43.5 (empty fibers) to 56 nm in the PVA/MMT‐3% and bead‐less nanofibers were formed with the maximum diameter distribution and mean diameter value of 45–80 and 62 nm, respectively. The d‐spacing was increased significantly from 1.004 in MMT to 1.684 nm in MMT‐urea, indicating the intercalation of urea occurred successfully. Furthermore, elemental analysis results showed that the intercalated MMT‐urea contained 30.4% nitrogen. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45957.

“…This process enables sensitive materials to be encapsulated within a polymeric fibrous matrix in a simple, one-step cost effective process [11]. It has already shown great promise in various pharmaceutical [12][13][14][15][16], food applications [17,18] and has recently gained interest in the cosmetic industry in perfumery [19,20] and FMs. For example, Camerlo et al [21] demonstrated the sustained release of limonene oil over 15 days by developing electrospun PVA fibers.…”

Introduction The stratum corneum is the biggest obstacle in cosmetics with respect to skin moisturisation. Many approaches have been taken to overcome the barrier, one of which is incorporating natural cosmeceuticals into cosmetic products to enhance moisturisation effects. Here, a commercial facemask formulation was electrospun to develop dry facemasks capable of hosting cosmeceuticals within the pores of incorporated mesoporous silica. Methods Ethanolic solutions containing 40% w/w of the marketed facemask (7th Heaven Dead Sea peel‐off facemask) and mesoporous silica were prepared and electrically processed at 30 μL min−1 at an applied voltage of 12 ± 2 kV. In vitro characterisation and release studies using fluorescein dye as a model probe were carried out. Results SEM images confirmed the fibrous nature of the resulting matrix; showing an average fiber diameter of 298.32 nm. The electrospun mask was found to be advantageous due to this fibrous nature providing high active loading capacity whilst demonstrating 100% probe release within 60 min. Contact Angle hysteresis, thermal analysis and Fourier Transform Infrared Spectroscopy (FTIR) presented evidence of compatibility and stability of and within the formulation. Conclusion Adapting the formulation of a commercial polymeric facemask into an electrospun facemask has shown the versatility of the electrospinning process; now successfully crossing over into the cosmetic industry.
