“…The fragrance release experiments were carried out at room temperature according to the previously reported procedure. 9 At regular intervals, ∼5 mg of sample was taken out from a desiccator with a small air outlet to analyze the fragrance residues by TGA. Each cumulative release percentage of fragrance was derived from three independent measurements and was expressed as the mean ± standard deviation.…”

“…The chemical barrier is based on the concept of profragrance, which is only applicable to fragrant compounds with functional groups. As for the physical barrier, there are concerns that the most commonly applied resinous-type capsules may cause microplastic contamination, resulting from the limited degradability of wall materials. , Recently, inorganic porous materials such as mesoporous silica spheres − and metal–organic frameworks (MOFs) − have been considered to be a promising matrix to encapsulate fragrance, flavor, and essential oils, in which the hosts can stabilize and slow down the evaporation of active ingredients due to the pore/channel confinement effect.…”

Volatility is an inherent fragrance attribute and typically implies a reduced perception over time. One possibility to elongate odor perception is utilizing controlled fragrance-delivery systems. Herein, the Y type of faujasite with different extraframework cations (abbreviated as ZY, where Z represents Na + , Ca 2+ , or La 3+ ) was examined as potential carriers for fragrance entrapment and delivery. D-Limonene (Lim) and linalool (Lol) as model fragrances were loaded in the pore space of Y zeolites, yielding composites FG@ZY (FG = Lim, Lol). It was found that the fragrance release profiles correlate highly with the cationic species located in the nonframework. The retention of fragrances in matrices increases in the order NaY < CaY < LaY for either limonene or linalool. Interestingly, the release rate of limonene was significantly slower than that of linalool when encapsulated in the same zeolite, although neat limonene has a much higher saturated vapor pressure than linalool. For instance, the total fraction of aroma released from Lim@LaY over 30 days was about 10%, while the value was ∼20% for Lol@LaY. Based on the density functional theory calculations, the above results could be well rationalized by the electrostatic attraction and shape selectivity of microporous matrices to the dopant molecules.

“…In addition to azobenzene, additional light-stimulating responsive materials and approaches are applied to encapsulation. Wang, Jiang, et al (2020) used situ polymerization of dopamine to encapsulate, and surface-functionalize nanosilica previously adsorbed with aromatic substances under an alkaline environment. The surface coating of PDA acts as a controlled-release switch, triggered by light, which converts light energy into thermal energy to release the fragrance.…”

Essential oils (EOs) are volatile aromatic compounds derived from spice plants and fragrant animals. Its insecticidal, antioxidant, and antibacterial properties, among others, have a significant research value. However, the unstable components severely restrict the applications of essential oils. Therefore, selecting the appropriate encapsulating material and the controlled-release mechanism is crucial to provide the best bioavailability and stability of essential oils. At present, it has been reported that several encapsulating materials are being employed to release essential oils to alleviate the issue of instability and volatility. This study will summarize the frequently utilized encapsulating materials and controlled-release methods for essential oils in recent years and give insight into the further design of encapsulating systems, development of bioactivity, and expansion of essential oil application sectors. Novelty impact statement:1. Mesoporous silica and zeolites are being studied for use as encapsulating materials for essential oils.2. Natural encapsulating materials have applicability in the food industry.3. Light and temperature-stimulating responses are suitable for sustained controlled-release for essential oils.
