“…This class of materials is listed as Generally Recognized as Safe (GRAS) by the FDA USA in 21 e-CFR (electronic Code of Federal Regulation) part 182.20 [4][5][6]. There are various essential oils already used, and the cinnamon EO has more than 160 separate and identified components, such as terpenoids and phenylpropanoids, with cinnamaldehyde being the most representative component [7,8].…”

Cinnamon Essential Oil Nanocellulose-Based Pickering Emulsions: Processing Parameters Effect on Their Formation, Stabilization, and Antimicrobial Activity

et al. 2021

This work aimed to prepare nanocellulose-based Pickering emulsions using cinnamon essential oil. Different formulations were investigated by varying the preparation time, homogenization speed, oil and nanocellulose concentration, and morphology. The emulsions were first characterized by droplet size, morphologies, and storage stability. The Design of Experiments (DoE) was used to evaluate the parameter’s effects on the emulsions’ stability, and the emulsions with optimum particle size and stability were evaluated by antimicrobial activity. The more stable emulsions required higher energy in the system to obtain efficient emulsification. The cellulose nanocrystal (CNC) emulsions showed a 30% oil volume as a constant to obtain a low creaming index (34.4% and 42.8%) and zeta potential values around −29 mV, indicating an electrostatic stabilization. The cellulose nanofiber (CNF) emulsions showed 100% stability after a month using a 20% oil volume as a constant and Zeta potential values around −15 mV, indicating a steric stabilization. CNF-emulsions’ inhibition halos for Bacilus subtilis were 30.1 ± 3.7% smaller than those found in CNC-emulsions (65 ± 2.9 mm), while Pseudomonasaeruginosas almost do not present differences in the inhibition halos. These results suggest that the nanocellulose morphology may promote a regulation on the EO migration to the medium, as well that this migration ratio does not affect the bacteria.

“…Para as amostras com extrato de cravo e canela dentro do prazo vigente, não houve crescimento de microrganismos para as mesmas condições experimentais, mostrando a ação antimicrobiana provocada pela adição dos extratos aquosos das especiarias empregadas. A barreira ao crescimento aparente de microrganismos pode ser atribuída ao eugenol (cravo) e cinamaldeído (canela), conforme descrito na literatura, [15][16][17][18] presentes nos óleos essenciais das especiarias adicionadas aos filmes, corroborando como os resultados obtidos neste trabalho. O mecanismo de inibição do eugenol acontece a partir da inativação do crescimento microbiano, já para o cinamaldeído, ocorre através da inibição da captação de glicose.…”

“…O mecanismo de inibição do eugenol acontece a partir da inativação do crescimento microbiano, já para o cinamaldeído, ocorre através da inibição da captação de glicose. [16][17][18] Já nos filmes com infusão de especiarias vencidas, o crescimento foi aparentemente mais rápido e volumoso, quando comparado ao controle, comprovando que o prazo de validade deve ser respeitado para obter as propriedades desejadas. Uma provável explicação para que não tenha ocorrido a inibição de crescimento de microrganismos, é a degradação dos óleos essenciais presentes na canela e no cravo, levando ao comprometimento de seus princípios ativos como o cinamaldeído e o eugenol.…”

“…Alguns estudos demonstram que o efeito bactericida do cinamaldeído deve-se à inibição da captação de glicose pela bactéria, interferindo assim no metabolismo energético do microrganismo. 18 O experimento proposto nesse artigo utiliza materiais de fácil acesso e baixo custo como o amido de milho e a glicerina, ambos de uso doméstico, a fim de produzir filmes termoplásticos. Através da incorporação dos extratos aquosos de especiarias alimentícias no preparo dos filmes, foi possível identificar a ação antimicrobiana do cravo e da canela de forma comparativa e visual.…”

The proposed experiment studies the antimicrobial properties of spices, cloves and cinnamon. Materials of easy access and low cost were used, aiming that the experimental procedure can be applied in laboratory classes of undergraduate courses. In this context, corn starch films were produced with infusions of spices. To facilitate the handling of the film, a plasticizer, glycerol, was added. The films were prepared from solutions and dried at room temperature. The visual analysis, documented by photos, was performed daily for 7 days. The visual comparison of the films was performed with the control (without spices), cloves and cinnamon within the expiration date, and with the same expired spices. The total duration of the experiment was one week, with the preparation of the films made in the first class, followed by the daily monitoring of the samples and the closing of the experiment in the next week's class. It was possible to observe the gradual growth of microorganisms in the control films and those prepared with extracts of cloves and cinnamon out of date. While for films prepared with cloves and cinnamon within the current validity period, microbial formations were not observed.

“…Cinnamaldehyde is the major compound of cinnamon ( Cinnamomum zeylanicum ) essential oil. Its antimicrobial activity has been widely reported, as well as its anti-inflammatory, angiogenic, and healing action [ 28 ]. Among its mechanisms of action are changes in the cell membrane by altering the lipid profile, inhibition of ATPase, inhibition of cell division, inhibition of gram-negative wall porins, inhibition of motility, inhibition of quorum sensing and biofilm formation, as well as synergistic action with antibiotics [ 29 ].…”

Background Natural products represent important sources of antimicrobial compounds. Propolis and compounds from essential oils comprise good examples of such substances because of their inhibitory effects on bacterial spores, including bee pathogens. Methods Ethanol extracts of propolis (EEP) from Apis mellifera were prepared using different methods: double ultrasonication, double maceration and maceration associated with ultrasonication. Together with the antimicrobial peptides nisin and melittin, and compounds present in the essential oils of clove ( Syzygium aromaticum ) and cinnamon ( Cinnamomum zeylanicum ), assays were carried out on one Bacillus subtilis isolate and Paenibacillus alvei (ATCC 6344) against vegetative and sporulated forms, using the resazurin microtiter assay. Synergism with all the antimicrobials in association with tetracycline was verified by the time-kill curve method. Potassium and phosphate efflux, release of proteins and nucleic acids were investigated. Results EEPs showed the same MIC, 156.25 µg/mL against B. subtilis and 78.12 µg/mL against P. alvei . The peptides showed better activities against B. subtilis (MIC of 12 µg/mL for melittin and 37.50 µg/mL for nisin). Antimicrobials showed similar inhibitory effects, but cinnamaldehyde (39.06 µg/mL) showed the best action against P. alvei . Melittin and nisin showed the greatest capacity to reduce spores, regarding B. subtilis there was a 100% reduction at 6.25 and 0.78 µg/mL, respectively. Concerning P. alvei , the reduction was 93 and 98% at concentrations of 80 µg/mL of melittin and 15 µg/mL of nisin. EEPs showed the highest effects on the protein release against B. subtilis and P. alvei . Nucleic acid release, phosphate and potassium efflux assays indicated bacterial cell membrane damage. Synergism between antimicrobials and tetracycline was demonstrated against both bacteria. Conclusion All antimicrobials tested showed antibacterial activities against vegetative and sporulated forms of P. alvei and B. subtilis , especially nisin and melittin. Synergism with tetracycline and damage on bacterial cell membrane also occurred.
