“…The EP‐1 and EP‐6 extract showed an endothermic peak in a temperature range from 50 to 65°C in cycles 1 and 3 (Figure 2). This temperature, according to Chen et al 28 corresponds to the fusion of the polyisoprenes and lipophilic compounds present in the extracts. This is because these authors analyzed trans ‐polyisoprenes and identified an endothermic peak in the temperature range from 40 to 60°C.…”

Jackfruit latex is a residue from the agricultural production of this fruit, which does not have an application in the food or pharmaceutical industry. The objectives of the study were to (1) extract the polyisoprenes from jackfruit latex using the surfactant sodium lauryl sulfate, and (2) characterize their physicochemical and techno-functional properties. The chemical composition, foaming and emulsifying capacity, and thermal behavior. According to the proximal chemical analysis of the extracts, the major content were lipophilic compounds (89%), including polyisoprenes. Regarding the emulsifying properties, the concentrates extracts showed intermediate values for the emulsifying activity index (32-59 m 2 /g) and stability times from 15 to 95 min. The thermal analysis showed endothermic events (50-65 C) associated with the melting of the concentrate, as well as exothermic events related to the crystallization of the polyisoprenes. The FTIR spectra indicates the presence of the polyisoprenes in the extracts, the stretching of the C═C bonds in 1704 at 1712 cm À1 are characteristic of cis-1,4 polyisoprene bonds, and at 980 cm À1 the C H bending. The physicochemical and techno-functional properties of polyisoprene extracts indicate that they could be used in emulsions or electrohydrodynamic encapsulation processes.

Polymeric nanofibers have appeared as unique one-dimensional nanomaterials. Nanofibers possess exceptionally high specific surface area and essential properties. Various polymeric nanofibers and nanocomposite nanofibers have been developed using thermoplastic and thermosetting matrices and organic and inorganic nanoparticles. This review documents the worth of nanofiber technology regarding the synthesis, morphology, physical properties, and applications of the nanostructures. The nanofiber surface morphology and diameter directly influence the physical characteristics such as electrical conductivity, mechanical properties, and thermal stability. Fiber processing techniques and related parameters also affect their texture and properties. In this regard, electrospinning is frequently used to form polymeric nanofibers and nanocomposite nanofibers. Electrospun nanofibers having large surface area and excellent fiber orientation, alignment, and morphology. The polymer nanocomposites with different nanofillers (carbon nanotube, graphene, carbon nanofibers, and other nanoparticles) have been processed into high performance electrospun nanofibers. Electrospun nanomaterials have been applied in engineered structures, nanofibrous membranes, electronic devices, tissue engineering, drug delivery, antibacterial materials and other biomedical applications. Henceforth, this is a comprehensive review on physical characteristics, morphology, processing aspects, and application areas for polymeric and nanocomposite nanofibers.
