“…During the dispersion process, 10 µL of OEO (5.0% v/v doTERRA Intl. CAS number 8007-11-2, O. vulgare) and 0.1% w/w VT-Pro bovine collagen were added (Makimat, CAS number 9007-34-5) (Cheng et al, 2022;Hernández et al, 2023;Wang et al, 2020;Zhong et al, 2023). Once a homogeneous dispersion was achieved, the freezing process was carried out following the protocol described by Coria- Hernández et al (2021) to form the cryogels until completing three freeze-thawing cycles.…”

“…Among its bioactive components stand out carvacrol and thymol, which given their nature could alter the permeability of the cell membrane and show good antibacterial activity against Gram‐negative bacteria. Therefore, promoting its use in edible coatings and films could lead to improvements in the mechanical, barrier, and solubility properties of products added with the oil (Hernández et al., 2023; Plati & Paraskevopoulou., 2022; Valle‐Garcia et al., 2019; Zhong et al., 2023).…”

Cryostructured gels, better known as cryogels, are a very important emerging class of biomaterials that have diverse applications in food preservation. This work shows a novel alternative to prepare a cryostructured composite coating made from a blend of xanthan, bovine collagen, and oregano essential oil. The composite coating was suitably applied onto the surface of preservative‐free biscuits which were stored for 15 days at 25 ± 2°C and 52% ± 1% relative humidity. The evaluation focused mainly on the changes in the physicochemical, textural, and microbiological characteristics of the biscuits. It was found that the coated samples significantly (p < 0.05) decreased moisture absorption, water activity, and fungal growth. However, the composite coating minimally impacted the quality of biscuits in terms of color, texture profile, and surface microstructure. Overall, the cryostructured composite coating constitutes an advance in technological strategies aimed at the preservation of baked products. This will allow, in the future, the development of novel coatings on bakery products to generate new trends in the conservation of their properties and extension of shelf life. This could be achieved through the implementation of new technologies in the food industry, with the aim of making them more environmentally friendly and contributing to the generation of less plastic waste.Practical ApplicationThe study and application of cryogels, as innovative systems in the food industry, allow to expand and diversify the materials that can function as coatings to maintain some quality characteristics, in this case in bakery products, so it is important to analyze their effects and consider them to improve conservation processes.

“…Traditional intervention strategies, such as synthetic chemical additives and antibiotics, focus on attenuating pathogenic bacteria while ignoring the hazardous toxins secreted by them; moreover, these methods are replete with many unsatisfactory application bottlenecks, such as potential side effects and antimicrobial resistance. , Fortunately, research has increasingly indicated that natural compounds represented by dietary polyphenols (e.g., tea polyphenols) possess superior pharmacological properties, long-term biosafety, and environmental-friendliness and thus are promising candidates around which novel intervention strategies can be developed. ,, Epigallocatechin gallate (EGCG), the most abundant polyphenol in tea, has attracted considerable attention for its multifunctional nature, such as antibacteriotoxin, anti-inflammatory, antitumor, and antioxidant activities. , These properties make EGCG a promising candidate for preventing foodborne diseases caused by bacterial toxins. According to a previous study, EGCG could ameliorate dextran sulfate sodium (DSS)-induced colitis in mice via gut microbiota modulation .…”

Natural phytochemicals have attracted increasing attention because of their promising ability to tackle bacteriotoxin-induced public safety concerns. However, it is unclear how natural phytochemicals regulate the intestinal barrier dysfunction caused by bacteriotoxin, such as staphylococcal enterotoxin A (SEA). This study aims to illustrate the in vitro and in vivo protective mechanism of epigallocatechin gallate (EGCG) on SEA-triggered intestinal barrier damage and inflammation. Results show that EGCG alleviates intestinal barrier damage by effectively inhibiting SEA-induced intestinal permeability increase, tight junction protein and mucin loss, and intestinal cell apoptosis. EGCG also reduces intestinal inflammation by suppressing the TLR4-NF-κB/MAPKs-NLRP3 pathway. Importantly, EGCG reverses gut microbiota dysbiosis and short-chain fatty acid (SCFA) content decrease induced by SEA. It is worth noting that this study also detects the direct interaction between the phytochemical and virulence factors and finds that EGCG effectively not only inhibits the secretion of SEA but also binds with the secreted SEA to attenuate its toxicity. Taken together, EGCG mitigates SEA-induced intestinal barrier dysfunction via gut microbiota SCFA-mediated TLR4-NF-κB/MAPKs-NLRP3 inflammatory cascade inhibition. Overall, this research provides enlightening insight into the application of bacteriotoxin-targeting natural compounds in the field of food safety and human wellness.

“…Recently, the oregano plant has gained significant recognition as an herbal medicine, supported by robust scientific evidence. Oregano plant is very influential against Gram-positive and Gram-negative bacteria (Zhong et al, 2023). The most common compounds in the oregano plant are carvacrol, thymol, tannins, phenols, and flavonoids (Chevallier, 2016).…”

Klebsiella pneumonia (K. pneumonia) and Staphylococcus aureus (S. aureus) are pathogenic bacteria causing various infectious diseases in humans and animals. Currently, herbal ingredients are widely used as antibacterial agents to combat bacterial infections due to their lower side effects, compared to chemical drugs. One such plant with medicinal promise as an antibacterial agent is the oregano plant (Oregano vulgare). It contains substances, such as tannin, flavonoids, carvacrol, thymol, and saponin. Therefore, the current study was conducted to regularly compare the in vitro antibacterial potential of ethanol extract essential oil oregano (Oregano vulgare) on K. pneumonia and S. aureus. In this research, the diffusion method using discs was employed to observe the inhibition zones, while the dilution tube method was utilized to determine the minimum inhibitory concentration (MIC) of the ethanol extract and essential oil of oregano against the test bacteria. The bacterial treatment group received the test material at concentrations of 100%, 50%, 25%, and 12.5%. The obtained data were analyzed descriptively in terms of zone inhibition and MIC values. According to the disc diffusion test, the essential oil of oregano demonstrated greater efficacy as an antibacterial agent against K. pneumoniae at a concentration of 100%, resulting in an average inhibition zone of 18 mm. Conversely, for S. aureus, a concentration of 1.5% of the essential oil exhibited higher effectiveness, yielding an average inhibition zone of 30 mm. Based on the MIC values, the essential oil was more effective as an antibacterial for K. pneumonia at a concentration of 0.2% (2 mg/mL), while for S. aureus it was more effective at a concentration of 0.19% (1.9 mg/mL).
