“…However, this method had the added advantage of good control over the microcapsules' morphology, size, and wall thickness. [66] Sonication-aided methods have also recently been reported for the encapsulation of fragrances. Siva et al encapsulated cumin aldehyde and isoeugenol within a methyl-𝛽-cyclodextrin inclusion complex using ultrasonication followed by freeze-drying to produce an inclusion complex which increased the stability of the volatile core materials as well as improved antioxidant and antibacterial activity.…”

Fragrances are ubiquitously and extensively used in everyday life and several industrial applications, including perfumes, textiles, laundry formulations, hygiene household products, and food products. However, the intrinsic volatility of these small organic molecules leaves them particularly susceptible to fast depletion from a product or from the surface they have been applied to. Encapsulation is a very effective method to limit the loss of fragrance during their use and to sustain their release. This review gives an overview of the different materials and techniques used for the encapsulation of fragrances, scents, and aromas, as well as the methods used to characterize the resulting encapsulation systems, with a particular focus on cyclodextrins, polymer microcapsules, inorganic microcapsules, block copolymer micelles, and polymersomes for fragrance encapsulation, sustained release, and controlled release.

“…TGA is employed to determine the encapsulation efficiency of hybrid nanofibers, the stability, and the solvents evaporation of formulations by measuring material weight (loss or gain) as a function of altering the heating temperature ( Waghmare et al, 2018 ; Islam et al, 2019 ; Ye et al, 2021 ).…”

Nanotechnology is one of the most promising technologies available today, holding tremendous potential for biomedical and healthcare applications. In this field, there is an increasing interest in the use of polymeric micro/nanofibers for the construction of biomedical structures. Due to its potential applications in various fields like pharmaceutics and biomedicine, the electrospinning process has gained considerable attention for producing nano-sized fibers. Electrospun nanofiber membranes have been used in drug delivery, controlled drug release, regenerative medicine, tissue engineering, biosensing, stent coating, implants, cosmetics, facial masks, and theranostics. Various natural and synthetic polymers have been successfully electrospun into ultrafine fibers. Although biopolymers demonstrate exciting properties such as good biocompatibility, non-toxicity, and biodegradability, they possess poor mechanical properties. Hybrid nanofibers from bio and synthetic nanofibers combine the characteristics of biopolymers with those of synthetic polymers, such as high mechanical strength and stability. In addition, a variety of functional agents, such as nanoparticles and biomolecules, can be incorporated into nanofibers to create multifunctional hybrid nanofibers. Due to the remarkable properties of hybrid nanofibers, the latest research on the unique properties of hybrid nanofibers is highlighted in this study. Moreover, various established hybrid nanofiber fabrication techniques, especially the electrospinning-based methods, as well as emerging strategies for the characterization of hybrid nanofibers, are summarized. Finally, the development and application of electrospun hybrid nanofibers in biomedical applications are discussed.

“…Under the conditions of simulated saliva pH 6.8 and temperature 32 °C, the drug release characteris- tics of menthol powder were investigated, and the results showed that the drug release rate of menthol was higher than eugenol. Ye et al [23] successfully applied the coaxial electrostatic atomization technique to encapsulate volatile fragrances in a silk fibronectin matrix using L-menthol as the core material and modulating its structural properties by varying the ratio of components in the core shell and matching it to the process parameters. Ades et al [9] encapsulated menthol and menthone in pure straightchain starch, corn starch, and waxy corn starch and found that menthol inclusion complexes were incubated in simulated saliva and completely released after 4 h of 𝛼-amylase hydrolysis.…”

Menthol is a well‐known antibacterial, anticancer, and cooling agent, but its low water solubility, poor stability, and high volatility have limited its applications. In the present study, octenyl succinate starches (OSAS) are hydrolyzed using pullulanase to acquire glucans with different molecular weights and substitution degrees. They are used to encapsulate menthol by formation of inclusion complexes (Enzymatically hydrolyzed OSA Starch complex with Menthol [E‐OSAS‐MEN]). Thermogravimetric analysis (TGA) shows the inclusion complexes have higher thermal stability than those of glucans. The smaller the particle size and polydispersity index of the menthol inclusion complexes, the larger the absolute value of the zeta potential. Gas chromatography‐mass spectrometry shows that E40‐OSAS‐MEN possesses the highest encapsulation efficiency and loading capacity of all inclusion complexes. The inclusion complex is stable against pH and temperature (4°C–100°C), and the released menthol in inclusion complexes ranges from 5% to 25%. The inclusion complex is released faster in simulated saliva containing α‐amylase, and menthol is completely released 5 h after enzymolysis. In contrast, only 18% of menthol is released in the absence of α‐amylase in simulated saliva. The present study provides valuable information as a guidance to develop chewing gums for controlled release of menthols.
