Summary: This study successfully formulated highly stable and water-dispersible litsea cubeba essential oil nanoemulsions using ultrasonic emulsification, medium-chain triacylglycerol (MCT) and phosphate-buffered saline (PBS). The nanoemulsions showed improved water solubility, stability, and bioactivities (antibacterial, antioxidant and antibiofilm properties) after emulsification, making them a potential novel food preservative.

Summary: This study aimed to evaluate the microbiological quality of deer meat treated with Litsea cubeba essential oil (dissolved in rapeseed oil at concentrations of 0.5% and 1%) and vacuum packaging. The results showed that no coliform bacteria were detected in the samples treated with 1% Litsea cubeba essential oil throughout the storage period. The most frequently isolated bacteria from deer meat were Pseudomonas ludensis, Pseudomonas corrugata, Pseudomonas fragi, Bacillus cereus, Staphylococcus epidermidis, and Sphingomonas leidyi.

Summary: Incorporating Litsea cubeba essential oil into soft lining materials inhibited the growth of Candida albicans and Streptococcus mutans without affecting cytotoxicity and surface hardness. The higher the concentration of LCEO, the greater the inhibitory effect on oral pathogens without compromising the integrity of the materials.

Summary: This study found that Litsea cubeba essential oil (LC-EO) has antimicrobial activity against Cronobacter sakazakii strains, and its mechanism involves increasing reactive oxygen species production, compromising cell membrane integrity, and causing cellular damage. Additionally, LC-EO effectively inhibited C. sakazakii biofilms and showed potential as a natural antimicrobial agent in the dairy industry.

Summary: This study aimed to prepare active and biodegradable methylcellulose films and assess their properties after incorporating cinnamon and litsea cubeba essential oils. The addition of essential oils modified the properties of the methylcellulose films, resulting in smooth and homogeneous surfaces. The film with cinnamon oil demonstrated higher antibacterial activity against Staphylococcus aureus and Escherichia coli, while the film with litsea cubeba oil showed higher antioxidant activity against ABTS radical. Both films biodegraded within 20 days in black sand and beach soil. The film with litsea cubeba oil as an antioxidant packaging and the film with cinnamon oil as an antibacterial packaging displayed the highest potential as active packaging.

Summary: The purpose of this experiment was to investigate the effects of Litsea cubeba essential oil (LCO) on the growth performance, blood antioxidation, immune function, apparent digestibility of nutrients, and fecal microflora in fattening pigs. The results showed that adding 250 mg/kg LCO in the diet of pigs improved their growth performance, blood physiological and biochemical indicators, antioxidant level, and nutrient digestibility. LCO also showed potential as a replacement for chlortetracycline (CTC).

Summary: This study aimed to determine the effects of dietary Litsea cubeba essential oil (LEO) supplementation on various aspects of weaned piglets. The results showed that high-dose LEO supplementation improved growth performance, immune function, antioxidant level, intestinal morphology, and microbial composition. LEO supplementation also increased the concentration of short chain fatty acids in the cecum and colon.

Summary: This research developed a new, efficient, and safe antimildew for postharvest storage of peanut kernels. The antimildew, cinnamon-Litsea cubeba compound essential oil (CLCEO) microcapsule (CLCEOM), was synthesized using CLCEO as the core material and beta-cyclodextrin as the wall material. The experiments showed that CLCEOM had significant antifungal effects on Aspergillus spp. strains even after 2 months of storage at 4 degrees Celsius. It also reduced the number of fungal colonies, the abundance of Aspergillus spp., and aflatoxin B1 content in peanut kernels, and had positive effects on slowing down the increase in acid value of peanut oil without causing any adverse effects on viability and sensory properties during storage.

Summary: This study developed a novel xanthan-gum-based edible coating embedded with nano-encapsulated Litsea cubeba essential oil (LC-EO) for salmon preservation. The results showed that LC-EO displayed potent antibacterial activity against Vibrio parahaemolyticus (V. parahaemolyticus) and the coating treatment performed the best preservative properties, delaying oxidation and controlling the growth of V. parahaemolyticus.

Summary: This study demonstrated that Poly-L-aspartic acid (PASP) can damage Staphylococcus aureus (S. aureus) biofilms by affecting bacterial adhesion, metabolic activity, and extracellular polymeric substances. The generation of eDNA was reduced by 49.4% after treatment with PASP. Nanoparticles prepared by PASP and hydroxypropyl trimethyl ammonium chloride chitosan showed long-lasting anti-biofilm activity and significant permeation and dispersion effects on biofilms. The sensory properties of chicken breast were not affected by these nanoparticles.

Summary: This study demonstrates the potential of Litsea cubeba essential oil (LC-EO) and its main component, citral, as anti-virulence agents targeting listeriolysin O (LLO) of Listeria monocytogenes. The results show that citral can significantly decrease the hemolytic activity of LLO by inducing conformational changes and forming covalent bonds with specific residues. This research provides a new approach for the development of LLO-targeting anti-virulence agents and expands the application of LC-EO in food microbiological safety.

Summary: Environmental issues caused by plastic packaging materials have become increasingly serious, leading to extensive research on environmentally friendly active packaging materials. In this study, Litsea cubeba essential oil loaded soy protein isolate nanoparticles (LSNPs) were successfully fabricated with appropriate particle size, high storage stability, and salt solution stability. These LSNPs were then added to lentinan edible films. The results showed that the lentinan film with LSNPs in the volume ratio of 4:1 had excellent physical properties and exhibited antibacterial, oxidation resistance, and thermal stability effects.
