“…After 28 days, all tomatoes in all experimental groups were contaminated with fungi. These results demonstrate the potential of the gel as a system that may change any regular packaging into active packaging: When the gel is applied to the inner side of the packaging, it releases volatile antibacterial and antifungal compounds that alter the environment inside the packaging, resulting in the extension of postharvest shelf life. , …”

Volatile oils exhibit numerous biological activities including antimicrobial, wound-healing, and antioxidant. The domestic and medical use of these oils is, however, limited by their volatility, hydrophobic nature, and susceptibility to degradation reactions in the presence of air, light, and moisture. Here, we describe a three-dimensional (3D) structured organogel system composed of a polymeric matrix (organogelator) and three volatile oilslinalool, citral, or Mentha arvensis oilserving as the organic phase. Increasing organogelator concentrations led to an increase in both the storage moduli and the loss moduli attributable to a higher degree of interaction between adjacent polymeric chains. Volatile oils were released into the head compartment in a controlled manner, reaching a plateau within 2 h. The antifungal activity of the various organogels against the common dermatophyte Theridion rubrum was evaluated in vitro. While organogels of all sizes showed complete inhibition for citral, a dose-dependent effect was observed for linalool and mentha oil, with the largest disks displaying clear antifungal activity and the smallest ones displaying negligible activity. In a follow-up experiment on an onychomycosis model using infected horse hooves, organogels exhibited marked antifungal activity. The ability of this system to extend the shelf life of fresh food products was also demonstrated. The versatility of the gel, the simplicity of its production, and its effectiveness make this system very attractive as a delivery platform for volatile oils.

Garlic essential oil is one of the natural antimicrobial agents which has a broad spectrum of inhibition against microbes. However, if directly applied to the packaging material, it will affect the tensile strength of the packaging. In order to overcome the weakness, this study has produced an antimicrobial active packaging with the concept of a headspace food system, the principle of this packaging is the adsorption of active compounds on a carrier material that can release them slowly. Garlic essential oil was adsorbed on zeolite nanofiber cellulose tablet composites. The effect of adding cellulose nanofibers to tablets has been investigated. The effectiveness of tablet composites was assessed by conducting a release test which was carried out by calculating the weight reduction of tablet composites every day for six days. Based on the release test, the addition of 3% nanofiber cellulose to the composite has a reliable ability to slow the release of garlic essential oil. Antimicrobial inhibition of e coli and s typhi bacteria was also tested using the agar diffusion method. Tablet composites with the addition of 3% nanofiber cellulose have a very strong inhibitory power against e coli bacteria and have moderate inhibition against s typhi bacteria

“…Currently, polyolefin like LDPE is used as antibacterial and antifungal films for smart packaging when blended with modified clay and carvacrol oil. 4 Rozenblit et al 5 have developed a new volatile antimicrobial oil–polyacrylic acid for prolonging shelf life of fresh foods. However, globally growing plastic consumption-based petroleum raises essential challenges regarding human health and environmental concerns, as these materials are dangerous due to either their production or their disposal in landfill locations and hence their marketability is limited.…”

Natural volatile antibacterial and anti-mycotoxin tea tree oil (TTO) with rice bran (RB) were used as a solid carrier for achieving a sustained release profile with high antimicrobial efficiency in polyethylene films. Acrylic acid (AAc) monomer was grafted onto a low-density polyethylene (LDPE) through melt blending using a Brabender Plasti-Corder. The low-density polyethylene-grafted acrylic acid (LDPE- g-AAc) was thoroughly characterized by attenuated total reflectance–Fourier transform infrared spectroscopy. LDPE and LDPE- g-AAc (80/20) were mixed with different contents of untreated RB and treated TTO/RB using melt blending to obtain sustainable composites, namely LDPE/LDPE- g-AAc/RB and LDPE/LDPE- g-AAc/TTO-RB, respectively. The effect of the addition of untreated and treated RB on the properties of biocomposites was assessed by using mechanical, barrier, and thermal properties. A prominent decrease in water vapor transmission rate occurred when adding 30 wt% of TTO/RB to LDPE/LDPE- g-AAc blend compared to virgin polymer. This decrease was due to the barrier effect of lignocellulosic material, particularly at high bio-filler content. The prepared biocomposites revealed good thermal stability when compared to virgin LDPE. Moreover, the biodegradability and antimicrobial properties of LDPE/LDPE- g-AAc/TTO-RB biofilms were enhanced with increasing TTO/RB contents from 10 phr to 30 phr due to the combination between LDPE- g-AAc and TTO. The obtained data revealed excellent possibility for using biopolymer grafted with antimicrobial TTO by adding RB for food packaging and biomedical purposes.
