“…Composite polymer nanofibers have attracted a lot of interest for use in various biomedical and food packaging applications in the last decade [ 24 , 25 ]. Owing to the abundance and low cost of polysaccharides, the composite nanofibers, made out of these natural polymers (e.g., cellulose, chitosan) together with biodegradable synthetic polymers (e.g., PLA, PVA), are suitable to be used in food packaging materials [ 26 , 27 ]. For instance, Jenab et al fabricated kefiran/polyethylene oxide nanofibers for food packaging [ 28 ]; however, to the best of our knowledge, other composite nanofibers of kefiran have not been fabricated so far.…”

Graphical abstract This study aimed to investigate parameters affecting the electrospinning of poly (vinyl alcohol) (PVA)/kefiran composite nanofibers. Accordingly, PVA/kefiran composite nanofibers were produced using the electrospinning of PVA, kefiran blend solutions under various electrospinning parameters (such as applied voltage, nozzle-to-collector distance, and polymer injection rate), and solution parameters (such as the ratio of polymers). PVA and kefiran solutions were prepared in 8% and 6% w/w, respectively. Kefiran was blended with PVA solution in different proportions: 70:30, 60:40, 50:50, 40:60, and 30:70. According to the scanning electron microscope (SEM) images, kefiran mixed with PVA in 40:60 ratios produced the best result in nanofiber production. Then, device parameters such as voltage (12, 15, 18, and 20 kV), distance (120, 150, 170, and 200 mm), and polymer injection rates (1, 1.5, 2, and 2.5 mL/h) were changed. The investigation of SEM images showed that the optimal condition for the fabrication of nanofibers was 18 kV, 200 mm, and 1 mL/h. The nanofibers produced in the optimal condition were uniform without knots or adhesion in a small diameter. It was also found that concentration can be regarded as the most effective parameter affecting the diameter of nanofibers. Moreover, the transmission electron microscopy (TEM) image proved that phase separation did not occur between the two polymers. Kefiran biopolymer extracted from fermented milk was used in fabrication of PVA/kefiran composite nanofibers using the electrospinning method.

“…The presence of amino and hydroxyl groups in the polymer backbone allows the chelation of metals and their adsorption from the water phase [1,6,16]. Among the chitosan-based materials (nanoparticles, gel beads, membranes, mats, sponges, fibers or hollow fibers) [17,18], chitosan nanofiber mats obtained by electrospinning are an attractive way to remove pollutants from aqueous solutions. This is mostly due to the nanometric diameter size of the resulting fibers providing structural advantages [9,19].…”

“…There are two types of collectors, rotating and static [21]. At laboratory scale, when using these collectors, an aluminum foil is wrapped over the collector which is removed at the end of the process along with the nanofibers [5,18,[21][22][23][24][25][26]. However, the nanofibers remain attached to the aluminum foil, making it difficult to recover them.…”

Electrospun chitosan-polyethylene oxide nanofiber mats were fabricated using a new collector design. Besides being reusable, it allows to assess the desired morphology of the mat in a quicker way. To test its efficiency, nonwoven mats designed for water treatment applications were prepared using conditions never been reported before. Under these conditions, continuous and flawless nanofibers of 151 ± 36 nm in diameter were achieved. Adsorption capacity of the mats for copper ions in aqueous solutions were investigated. Results showed that sorption equilibrium was achieved within 150 min with a homogenous distribution of copper ions within the nanofibrous mats. The pseudo-second order kinetic model best fitted the experimental data. The Langmuir isotherm best described the sorption process with a maximum adsorption capacity of 124 mg/g for trial temperatures ranging from 25 to 60 °C. Thermodynamic parameters (ΔG°, ΔH° and ΔS°) demonstrate that the adsorption was feasible, endothermic and spontaneous. The desorption potential and mat's reusability were also studied. Results reveal that the electrospun chitosan mats can be desorbed and reused up to 5 cycles without significant loss in adsorption performance.

“…Bioactive lipids can be directly or indirectly trapped within the biopolymer solution used to form the nanofibers prior to the electrospinning process. Nanochitin, nanocellulose, and nano-starch delivery systems have been produced using this method for food processing and packaging applications [ 48 , 49 ].…”

Bioactive lipids, such as fat-soluble vitamins, omega-3 fatty acids, conjugated linoleic acids, carotenoids and phytosterols play an important role in boosting human health and wellbeing. These lipophilic substances cannot be synthesized within the human body, and so people must include them in their diet. There is increasing interest in incorporating these bioactive lipids into functional foods designed to produce certain health benefits, such as anti-inflammatory, antioxidant, anticancer and cholesterol-lowering properties. However, many of these lipids have poor compatibility with food matrices and low bioavailability because of their extremely low water solubility. Moreover, they may also chemically degrade during food storage or inside the human gut because they are exposed to certain stressors, such as high temperatures, oxygen, light, moisture, pH, and digestive/metabolic enzymes, which again reduces their bioavailability. Nanotechnology is a promising technology that can be used to overcome many of these limitations. The aim of this review is to highlight different kinds of nanoscale delivery systems that have been designed to encapsulate and protect bioactive lipids, thereby facilitating their handling, stability, food matrix compatibility, and bioavailability. These systems include nanoemulsions, solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), nanoliposomes, nanogels, and nano-particle stabilized Pickering emulsions.
