“…Nanoencapsulation and nanoimbibition are prominent research directions regarding the sustained and controlled release of essential oils by significantly enhancing physicochemical stability, solubility, and bioavailability of essential oils . For instance, encapsulation using multilayer liposomes, solid lipid nanoparticles (SLNs), and nanoemulsions has been explored. − Zhu et al employed polylactic acid (PLA) modified by octenyl succinic anhydride chitosan (OSA-CS) as shell materials to encapsulate TTO to form long-term antibacterial and pH-responsive microcapsules . These nanocarriers can control the release of essential oils under specific conditions (such as pH changes, temperature shifts, or enzymatic action), thus, increasing their application value in food preservation, drug delivery, and cosmetics.…”

Plant essential oils and pesticides are commonly used methods for preventing and controlling agricultural pests and diseases. To address the challenges of volatility of essential oils and ultraviolet sensitivity of avermectin (AVM), herein, microfibrillated cellulose anchored with ammonium molybdate (MFC-POM) was constructed via the emulsion template method and the ion exchange process and applied as carriers for tea tree oils (TTO) and AVM to protect the active ingredients. The amount by anchoring of molybdenum oxygen cluster ions into cellulose skeleton was ∼29.54%. MFC-POM exhibited a relatively high loading capacity for both TTO and AVM of 52.23 and 42.12%, respectively. Meanwhile, TTO@MFC-POM possessed a long-term sustained release behavior fitting with logistic release kinetics model and held enhanced antibacterial activity compared to pure TTO and MFC-POM. AVM@MFC-POM exhibited pH-responsive release behavior with more AVM release under acidic and alkaline conditions. Furthermore, AVM@MFC-POM presented remarkable ultraviolet light resistance with a half-life nearly 30 times longer. MFC-POM also represented superior wetting properties and a noticeable increase in liquid retention on cucumber foliar surfaces. AVM@MFC-POM retained insecticidal toxicity, provided trace nutrient element Mo, and promoted germination and plant growth, thus exhibiting good biological safety. Overall, MFC-POM could serve as an effective carrier for protecting active ingredients and improving their effectiveness for agricultural disease and pest control.

“…Drying is a common and significant process to convert encapsulated particle emulsions into powders. It widens the application range of encapsulated EOs, increases their shelf life, and reduces the weight of the final product, resulting in a more economical transportation [12,25]. Spray-drying and freeze-drying (also referred to as lyophilization) are common drying methods used in the pharmaceutical and food industries.…”

Efforts to tap into the broad antimicrobial, insecticidal, and antioxidant activities of essential oils (EOs) are limited due to their strong odor and susceptibility to light and oxidation. Encapsulation of EOs and subsequent drying overcome these limitations and extend their applications. This study characterized freeze-dried (lyophilized) emulsions of eugenol (EU) and thymol (TY) EOs, encapsulated by chemically unmodified cellulose, a sustainable and low-cost resource. High-resolution scanning electron microscopy showed successful lyophilization. While the observed “flake-like” structure of the powders differed significantly from that of the emulsified microcapsules, useful properties were retained. Fourier transform infrared spectroscopy confirmed the presence of EOs in their corresponding powders and thermo-gravimetric analysis demonstrated high encapsulation efficiency (87–88%), improved thermal stability and resistance to evaporation, and slow EO release rates in comparison to their free forms. The lightweight and low-cost cellulose encapsulation, together with the results showing retained properties of the dried powder, enable the use of EOs in applications requiring high temperatures, such as EO incorporation into polymer films, that can be used to protect agricultural crops from microbial infections.
