“…For the biofilm-inhibitory or biofilm-degrading capacity of EOs or active compounds, the classical crystal violet staining assay, performed in 96-well microplate format, is most commonly used [ 66 , 72 , 73 , 74 ]; however, other methods, such as the TEMPO system (bioMérieux), VIDAS system (bioMérieux), or the discrete element method (DEM), have also been suggested [ 75 ]. Polystyrene, polypropylene, polyethylene, glass, and stainless steel are typically tested abiotic surface materials [ 31 , 45 , 72 ].…”

“…Considering the tests, we have to emphasize again that the effect of EOs can be strain-dependent. A good example demonstrating this was a recent study in which the EO of Melissa officinalis was tested on three strains of L. monocytogenes (LMG 13305, 16779, and 16780), and three different inhibition zone diameters were found: 38.4 ± 4.2 mm, 54.6 ± 1.3, mm and 48.6 ± 1.7 mm, respectively [ 74 ]. In the case of Schinus terebinthifolius Raddi, EOs were produced from both ripe and unripe fruits.…”

Listeria monocytogenes is a foodborne pathogen, the causative agent of listeriosis. Infections typically occur through consumption of foods, such as meats, fisheries, milk, vegetables, and fruits. Today, chemical preservatives are used in foods; however, due to their effects on human health, attention is increasingly turning to natural decontamination practices. One option is the application of essential oils (EOs) with antibacterial features, since EOs are considered by many authorities as being safe. In this review, we aimed to summarize the results of recent research focusing on EOs with antilisterial activity. We review different methods via which the antilisterial effect and the antimicrobial mode of action of EOs or their compounds can be investigated. In the second part of the review, results of those studies from the last 10 years are summarized, in which EOs with antilisterial effects were applied in and on different food matrices. This section only included those studies in which EOs or their pure compounds were tested alone, without combining them with any additional physical or chemical procedure or additive. Tests were performed at different temperatures and, in certain cases, by applying different coating materials. Although certain coatings can enhance the antilisterial effect of an EO, the most effective way is to mix the EO into the food matrix. In conclusion, the application of EOs is justified in the food industry as food preservatives and could help to eliminate this zoonotic bacterium from the food chain.

“…), juniper ( Juniperus communis L.), mint ( Mentha piperita L.), rosemary ( Rosmarinus officinalis L.), sage ( Salvia officinalis L.), clove ( Syzygium aromaticum L.), thyme ( Thymus vulgaris L.), lavender ( Lavandula angustifolia L.), and lemon balm ( Melissa officinalis L.) have demonstrated the ability to extend the shelf life of various food products. These extracts and oils exhibit bacteriostatic and fungistatic effects, attributed to the presence of biologically active compounds such as phenols, aldehydes, ketones, and terpenes [ 41 , 74 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ]. The application of these natural extracts has been explored for the preservation of cheeses, mousses, cereals, fruit and vegetable juices, mayonnaise, and meat products (see Table 3 ).…”

Ensuring the microbiological safety of food products is a pressing global concern. With the increasing resistance of microorganisms to chemical agents and the declining effectiveness of synthetic preservatives, there is a growing need for alternative sources of natural, bioactive compounds with antimicrobial activity. The incorporation of probiotics and plant extracts into food formulations not only enriches foodstuffs with microorganisms and phytochemicals with biologically active compounds, but also provides a means for product preservation. The current review considers the importance of the process of biological preservation for providing safe foods with high biological value, natural origin and composition, and prolonged shelf life, thereby improving consumers’ quality of life. To accomplish this goal, this review presents a series of examples showcasing natural preservatives, including beneficial bacteria, yeasts, and their metabolites, as well as phenolic compounds, terpenoids, and alkaloids from plant extracts. By summarizing numerous studies, identifying research challenges and regulatory barriers for their wider use, and outlining future directions for investigation, this article makes an original contribution to the field of biopreservation.

“…Plant essential oils (EOs) are natural products including the active constituents obtained from aromatic plants or medicinal plants by distillation, extraction, pressing and other methods, consistently praised as "liquid gold". They are rich in terpenes, aromatics and aliphatic active constituents, which have antioxidant, antibacterial, antiviral, antitumor and antidepressant effects, [1][2][3] extensively used in biopharmaceuticals, food additives, daily chemicals, biopesticides and other fields. [4][5][6][7] Compared to synthetic chemicals, natural plant EOs are playing increasingly important roles in the rehabilitation of fatigue, emotional disorders, insomnia and other sub-health, as well as in the treatment of chronic diseases.…”

The compound of essential oils (EOs) is a key approach to achieving the superimposed efficacy of plant EOs. In this article, grey correlation analysis was applied for the first time to explore the compound ratios and contribution between constituents and the bioactivity of the compound EOs. There were 12 active constituents shared in rosemary and magnolia EOs prepared by negative pressure distillation. With different proportions, these two EOs were blended and analyzed for the antioxidant, bacteriostatic and antitumor effects. According to the results of the inhibition circle, minimum bactericidal and inhibitory concentration, the most obvious inhibition effect of the compound EOs on different strains of bacteria was shown in Staphylococcus aureus. The results of antioxidant test showed that single EO from rosemary had the best antioxidant effect, and its EO content was directly proportional to the antioxidant effect. The cytotoxicity results showed that, there was a significant difference in the lethality of the compound EOs between tumor cells Mcf-7 (human breast cancer cells) and SGC-7901 cells (human gastric cancer cells). Furthermore, single EO from magnolia had an obvious inhibitory effect on the growth of Mcf-7 cells and SGC-7901 cells, and the cell lethality rate was as high as 95.19 % and 97.96 %, respectively. As the results of grey correlation analysis, the constituents with the maximal correlation of inhibitory effects on bacteria were as follows: S. aureus -Terpinolene (0.893), E. coli -Eucalyptol (0.901), B. subtilis -α-Pinene (0.823), B. cereus -Terpinolene (0.913) and Salmonella -α-Phellandrene (0.855). For the ABTS and DPPH scavenging effects, the constituents with the maximal correlation were (À )-Camphor (0.860) and β-Pinene (0.780), respectively. In terms of the effects of the active constituents of compound EOs on the inhibitory activities of tumor cells Mcf-7 and SGC-7901, the three active constituents of γ-Terpinene, (R)-(+)-β-Citronellol and (À )-Camphor were in the top three, and their correlation were Mcf-7 (0.833, 0.820, 0.795) and SGC-7901 (0.797, 0.766, 0.740). Our study determined the contribution degree of active constituents in the antibacterial, antioxidant, and antitumor bioactivities of rosemarymagnolia compound EOs, and also provided new insights for the research of EOs combination formulations.
