The antimicrobial activity of essential oils (EO) is associated with the presence of secondary metabolites synthesized by plants. Its mechanism of action involves the interaction of its hydrophobic components with the lipids present in the cell membrane of microorganism, resulting in metabolic damages and cell death. Spoilage and pathogenic microorganisms are contaminants in meat and meat products with considerable impacts on food quality and safety. Research shows the potential of applying essential oils in the preservation of meat food systems as compounds of low toxicity, extracted from a natural source, and as an alternative to consumer demand for healthy foods with a more natural appeal. In addition, there is a great diversity of plants from which essential oils can be extracted, whose antimicrobial activity in vitro and in meat and meat products has been proven.

Thyme and oregano essential oils (EOs) and their components have numerous applications in the pharmaceutical, food, and cosmetic industries owing to their antioxidant, antibacterial, antifungal, anti-inflammatory, antiviral, and immunological properties. We attempted to create new chemotypes through the hybridization of thyme and oregano for functional EO research and product development. Here, we used interspecific hybridization to create new thyme and oregano germplasms with new EO chemotypes.

Essential fatty acids (EFAs) in edible oils are crucial for human nutrition. However, their high unsaturation renders edible oils susceptible to oxidation during storage and processing. The addition of lipophilic antioxidants is an effective strategy to inhibit oxidation and safeguard the nutritional integrity of edible oils.

Characterization of key flavor compounds in cinnamon bark oil extracts using principal component analysis.

Food Res Int

January 2025

State Key Laboratory of Food Science and Technology, Jiangnan University, Wuxi, Jiangsu 214122, China. Electronic address:

Cinnamon is a widely used spice, known for its distinctive flavor and aromatic properties. Due to its lignified structure, the release of flavor components typically requires prolonged stewing (1-2 h). To simulate the release of flavor components during stewing, this study employed corn oil for extraction, avoiding the use of organic solvents.

The study investigated the perceptual interaction between two types of Rose damascena essential oil and two types of Angelica dahurica root essential oil. Using gas chromatography-olfactometer (GC-O) and gas chromatography-mass spectrometer (GC-MS), 24 and 25 aromatic compounds in Rose damascena essential oil and Angelica dahurica root essential oil were identified and quantified, respectively. Based on flavor dilution (FD) values and odor activity values (OAVs), 10 important aroma compounds in Rose damascena essential oil and 6 in Angelica dahurica root essential oil were identified.
