Óleo Essencial De Orégano (Origanum Vulgare L.) Na Produção De Filmes Ativos Biodegradáveis

Antifungal activity of essential oils of tea tree, oregano, thyme, and cinnamon, and their components

“…The antifungal activity of oregano essential oil has already been verified against the most varied microorganisms, such as B. cinerea, Penicillium italicum, and P. digitatum (Vitoratos et al, 2013). Such activity is related to specific components of this oil, such as carvacrol and thymol, that is their main active compounds (Paulo et al, 2021). Table 2 shows the components found in greater quantities in O. vulgare oil in different studies.…”

“…In Brazil, it is found mainly in the South and Southeast regions. The essential oil of O. vulgare is characterized by having a high content of phenolics and is also composed of monoterpene hydrocarbons, sesquiterpenes, and oxygenated monoterpenes (Paulo et al, 2021). Essential oil extraction is traditionally performed by steam distillation of leaves or buds but can also occur by hydrodistillation, CO 2 extraction, and supercritical fluid extraction.…”

“…Furthermore, its effectiveness against food-deteriorating bacteria has been highlighted in many studies (D'agostino et al, 2019). However, there are certain limitations regarding its use since it is degraded when exposed to high temperatures, pressure, light, and oxygen during food processing and can alter sensory characteristics depending on the concentration used (Paulo et al, 2021).…”

Advances and perspectives on the application of essential oils in food packaging films, coatings, and nanoencapsulated materials

“…The concentration of oregano EO used in the formulation of the films has been quite variable, depending on the type and concentration of biopolymers and plasticizer, which influences the antimicrobial and antioxidant activity by increasing shelf life, without altering sensory characteristic and functional properties of the films. The oregano EO also acts as a plasticizer, reducing hardness and increasing the elongation of the films (Paulo et al 2021).…”

“…Biodegradable films have the same function as conventional films used as packaging. They protect food against external agents and provide a barrier against the permeability of water, gases, and light (Paulo et al 2021). The presence of natural antimicrobial agents can confer antimicrobial activity to these films (Silva, R. S. et al 2020, Hamann et al 2021.…”
