Summary: Edible films (EFs) functionalized with essential oils, especially those encapsulated in β-CD, show great potential as bioactive packaging systems for food due to their antimicrobial and antioxidant activities. In this study, EFs containing thyme essential oil (TEO) encapsulated in β-CD were developed in three different formulae and their properties were investigated. The EF/ICs exhibited better moisture barrier properties, comparable antimicrobial activities, and strong antioxidant activities compared to EF/TEO.

Summary: In this study, temperature-regulated lavender oil (LavO)-@-nanocellulose (NC) microcapsules (LavO@NCms) were prepared and their properties were studied. The LavO@NCms showed net-like cross-linking patterns and high encapsulation efficiency. The release of LavO followed specific models and LavO@NCms exhibited prolonged toxicity against Sitophilus granaries. LavO@NCms have the potential to be a safe natural insecticide.

Summary: In this study, antibacterial microcapsules of cinnamon essential oil (CEO) were prepared using a complex condensation method. Chitosan quaternary ammonium salt (HACC) combined with gum arabic (GA) was used as the coated wall material. The optimal preparation conditions for the microcapsules were determined, and their morphology, size, composition, and thermal stability were characterized. The microcapsules showed slow release and prolonged antibacterial effect, making them potentially useful in the food, cosmetics, and medicine industries.

Summary: We developed PNIPAm-co-PEGDA hydrogel shelled microcapsules with a thin oil layer for tunable thermo-responsive release of small hydrophilic actives. By using a microfluidic device integrated with a temperature-controlled chamber, we were able to consistently produce the microcapsules using triple emulsion drops as capsule templates. The presence of an interstitial oil layer between the aqueous core and the hydrogel shell allowed for controlled release of the encapsulated substances upon reaching a critical temperature. Additionally, the incorporation of gold nanorods in the hydrogel shell enables spatiotemporal regulation of the active release using near infrared light.

Summary: This study aimed to develop an antimicrobial food preservation material based on kaolin (KL) encapsulated with thyme essential oil (TEO). The release of TEO in the TEO/KL composite was controlled by the relative humidity inside of food packaging. The antimicrobial results illustrated that the activity of Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Botrytis cinerea (B. cinerea) remarkably reduced after treating with the TEO/KL composite (1.0, 1.5 and 2.0 mg), and the inhibition rate reached over 99%. The cytotoxicity assays demonstrated good biocompatibility and biosafety of TEO/KL applied to food preservation. This composite also exhibited a desirable preservation effect on strawberries and grapes and displayed great potential in food industry.

Summary: The Maillard reaction products (MRPs) of whey protein and flaxseed gum prepared by ultrasonic assisted wet-heating have enhanced functional properties with higher grafting degree and expanded structures. These MRPs improve the water holding capacity, encapsulation efficiency, and stability of emulsion gels, leading to increased bioaccessibility of loaded astaxanthin. This highlights the potential of MRPs in enhancing protein functionality and serving as delivery carriers for bioactive compounds in the food industry.
