“…However, their applications in foods are limited because of some distinctive properties such as strong smell, high unpredictability, poor water dissolvability, and instability [ 19 ]. Furthermore, while EOs are unstable in the presence of light, heat, oxygen, and humidity, their volatile nature and hydrophobicity restrict their direct use in foods [ 205 , 206 ]. These problems could be solved by enhancing the water solubility and bioavailability, protecting bioactive compounds from extrinsic and intrinsic factors, and removing unpleasant odor and taste in order to use EOs in the food system [ 207 ].…”

The interest in using natural antimicrobials instead of chemical preservatives in food products has been increasing in recent years. In regard to this, essential oils—natural and liquid secondary plant metabolites—are gaining importance for their use in the protection of foods, since they are accepted as safe and healthy. Although research studies indicate that the antibacterial and antioxidant activities of essential oils (EOs) are more common compared to other biological activities, specific concerns have led scientists to investigate the areas that are still in need of research. To the best of our knowledge, there is no review paper in which antifungal and especially antimycotoxigenic effects are compiled. Further, the low stability of essential oils under environmental conditions such as temperature and light has forced scientists to develop and use recent approaches such as encapsulation, coating, use in edible films, etc. This review provides an overview of the current literature on essential oils mainly on antifungal and antimycotoxigenic but also their antibacterial and antioxidant activities. Additionally, the recent applications of EOs including encapsulation, edible coatings, and active packaging are outlined.

“…A wide variety of applications using complexes composed of CD and essential oils have been recently reviewed [ 119 , 120 ]. Still, the extensive research of CD/essential oil complexes has been conducted to improve the properties of essential oil [ 121 , 122 , 123 , 124 , 125 , 126 ]. For example, Abril-Sánchez et al presented the improved efficacy of the essential oil, citronellal, by encapsulating it using HP-β-CD [ 121 ].…”

Cyclodextrins (CDs) have drawn a lot of attention from the scientific communities as a model system for host–guest chemistry and also due to its variety of applications in the pharmaceutical, cosmetic, food, textile, separation science, and essential oil industries. The formation of the inclusion complexes enables these applications in the condensed phases, which have been confirmed by nuclear magnetic resonance (NMR) spectroscopy, X-ray crystallography, and other methodologies. The advent of soft ionization techniques that can transfer the solution-phase noncovalent complexes to the gas phase has allowed for extensive examination of these complexes and provides valuable insight into the principles governing the formation of gaseous noncovalent complexes. As for the CDs’ host–guest chemistry in the gas phase, there has been a controversial issue as to whether noncovalent complexes are inclusion conformers reflecting the solution-phase structure of the complex or not. In this review, the basic principles governing CD’s host–guest complex formation will be described. Applications and structures of CDs in the condensed phases will also be presented. More importantly, the experimental and theoretical evidence supporting the two opposing views for the CD–guest structures in the gas phase will be intensively reviewed. These include data obtained via mass spectrometry, ion mobility measurements, infrared multiphoton dissociation (IRMPD) spectroscopy, and density functional theory (DFT) calculations.

“…Both the PBAT film and the composite film had two weightlessness stages, namely, a slow decomposition stage and a severe decomposition stage. The presence of clear endothermic peak at the critical point of the two stages, and the fastest weight loss at 404.5 and 405.9 • C, with a difference of 1.4 • C confirmed the good compatibility of microcapsules and films [45].…”

“…At 70% and 50% RH, CA release reaches equilibrium on the 7th and 9th days, respectively, which means that SiO 2 -CA microcapsules exhibit a longer release time under low humidity conditions. Balaguer et al and Herrera et al found similar results control release of CA in gliadin films [44,45]. The effect of humidity on the release performance of SiO 2 -CA microcapsules might be explained by the presence of a large number of hydroxyl groups on the surfaces of SiO 2 -CA microcapsules.…”

The mesoporous silica wall materials can achieve controlled load and sustained-release of active agents. An antimicrobial nanoscale silica microcapsule containing cinnamaldehyde (CA) was prepared by the sol-gel method and applied in poly (butyleneadipate-co-terephthalate) (PBAT) film. The surface morphology, physical and chemical properties, and antibacterial properties of microcapsules and films were studied. The effects of different temperatures and humidities on the release behavior of microcapsules were also evaluated. Results showed that CA was successfully encapsulated in silica microcapsule which had a diameter of 450–700 nm. The antibacterial CA agent had a long-lasting release time under lower temperature and relative humidity (RH) environment. At low temperature (4 °C), the microcapsules released CA 32.35% in the first 18 h, and then slowly released to 56.08% in 216 h; however, the microcapsules released more than 70% in 18 h at 40 °C. At low humidity (50%RH), the release rates of microcapsules at the 18th h and 9th d were 43.04% and 78.01%, respectively, while it reached to equilibrium state at 72 h under 90% RH. The sustained release process of CA in SiO2-CA microcapsules follows a first-order kinetic model. Physicochemical properties of PBAT films loaded with different amounts of microcapsules were also characterized. Results showed that the tensile strength and water vapor transmission rate (WVTR) of the composite film containing 2.5% microcapsules were increased by 26.98% and 14.61%, respectively, compared to the raw film, while the light transmittance was slightly reduced. The crystallinity of the film was improved and can be kept stable up to 384.1 °C. Furthermore, microcapsules and composite film both exhibited distinctive antibacterial effect on Escherichia coli and Listeria monocytogenes. Therefore, SiO2-CA microcapsules and composite films could be a promising material for the active packaging.
