“…The water content of high alcohol concentration was low. This led to create high driving force between the system and more beads were formed in shorter time [19]. Similar result was reported by Zilberboim et al who found higher alcohol concentration as a dehydrating medium increase yield of encapsulation of oleoresin and aromatic esters of paprika.…”

“…High concentration of alcohol led to rapid bead formation due to low water content in the medium. This reduced the possibility of iron loss during beading [19]. This result supported by Gupta et al which confirmed that the increase in alcohol concentration in bead forming of encapsulated iron could improve the efficiency of iron encapsulation [6].…”

“…There are various techniques of bead forming in encapsulation process including spray drying, spray chilling or spray cooling, and extrusion coating [18]. An extrusion or dripping method is one of the simple method to obtain the bead [1], [19]. This process requires a dehydrating medium to obtain the desired bead of the encapsulated compound.…”

“…Ethanol have been reported as a dehydration medium in iron encapsulation [19], [22] but no report isopropyl alcohol (IPA) as dehydrating medium, even though IPA has potential for dehydrating medium. However, to the best of our knowledge, there is lack of information in comparing both dehydrating medium in iron encapsulation using deacetylated GM (DGM).…”

The success of encapsulation to protect iron from inhibitor degradation or oxidation depends on many factors including the excipient characteritics. Glucomannan, a neutral heterosaccharide, has a potential for the excipient. To improve the excipient performances, glucomannan is deacetylated to remove the acetyl groups by reacted with Na2CO3. This deacylated glucomannan is subject to bead formation after iron loading. The alcohol solution is commonly used in bead forming as dehydration medium during the encapsulation process. The objective of this work was to study the effect of alcohol on the bead performance of encapsulated iron using deacetylated glucomannan. The bead forming was conducted by dropping the excipient into ethanol and isopropyl alcohol (IPA) solution at various concentrations (50, 60, 70, 80 and 90%) and two condition temperatures (27-30° and 7-10°C). The encapsulation samples were subject to yield (YE) and efficiency of encapsulation (EE). The concentration of alcohol showed a positive impact on the yield and efficiency of encapsulation. Ethanol has a better performance compared with that of IPA regarding yield and efficiency of encapsulation. The optimum of yield bead formation (69.67%) and highest EE (66.80%) were obtained at 90% ethanol. Temperature of dehydration did not affect the YE and EE significantly.

“…The proteinaceous materials and methoxyl groups are present in both fractions of GT, albeit in smaller amounts (Verbeken et al, 2003;Weiping, 2000). The remarkable structural and functional properties of GT have recently been exploited in many non-food applications, such as tunable drug delivery systems, hydrogels, cryogel and xerogel blends, micro-encapsulations, nanocomposites for heavy metal ions removal, bioplastics, edible blend films and coatings and grafting copolymer flocculants for destabilization of carbon nano-tubes (Asghari-Varzaneh et al, 2017;López-Castejón et al, 2016;Mallakpour et al, 2018;Mostafavi et al, 2016;Niknia and Kadkhodaee, 2017;Pal et al, 2017; Sharma, 2017, 2014a).…”

The prospective uses of tree gum polysaccharides and their nanostructures in various aspects of food, water, energy, biotechnology, environment and medicine industries, have garnered a great deal of attention recently. In addition to extensive applications of tree gums in food, there are substantial non-food applications of these commercial gums, which have gained widespread attention due to their availability, structural diversity and remarkable properties as 'green' bio-based renewable materials. Tree gums are obtainable as natural polysaccharides from various tree genera possessing exceptional properties, including their renewable, biocompatible, biodegradable, and non-toxic nature and their ability to undergo easy chemical modifications. This review focuses on non-food applications of several important commercially available gums (arabic, karaya, tragacanth, ghatti and kondagogu) for the greener synthesis and stabilization of metal/metal oxide NPs, production of electrospun fibers, environmental bioremediation, bio-catalysis, biosensors, coordination complexes of metal-hydrogels, and for antimicrobial and biomedical applications. Furthermore, polysaccharides acquired from botanical, seaweed, animal, and microbial origins are briefly compared with the characteristics of tree gum exudates.

In this study, for the first time, calcium oxide (CaO)/polylactic acid nanoscaffolds were synthesized by co‐precipitation assistant reverse micelles method. The physical and chemical (physicochemical) properties of the structures as dental resin composites were also studied. Nanocomposite materials as primary and basic dental compounds can be conveniently applied as dental filling materials with a high esthetic quality. In this research nanoscaffolds act as a bed for nanoparticles and improve the mechanical and chemical (mechanochemical) properties, CaO nanoparticles were loading in polylactic acid nanoscaffold as a bioactivity polymer for usage in the dental resin composites. Mechanical properties of the dental resin composite containing CaO/polylactic acid nanoscaffold were calculated: the flexural strength (137.2 MPa), modulus (12.9GPa) and compressive strength (344.2 MPa). Potential of the basic nanoparticle and the products were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), dynamic light scattering (DLS), ultraviolet‐visible spectroscopy (UV‐visible) and atomic force microscopy (AFM) showed the size of the optimized nanostructures was about 85 to 120 nm. According to TGA results of polylactic acid nanofibers with thermal stability below 300°C these high thermal stability materials can be used as dental resin composites.
