“…In order to better ascertain the thermal protection offered by the electrospun PHBV fibers, the mass loss of the samples was determined at 230 • C since, at this temperature, eugenol was completely degraded (mass loss > 98%). This is in agreement with the findings reported by Cao et al (32), who indicated that neat eugenol completely degrades at 225 • C with a weight loss of 96%. Alternatively, it can be observed that PHBV remained highly stable at 230 • C (mass loss < 5%) since this temperature is below its T onset .…”

“…Different studies have reported multiple active and bioactive properties for essential oils, including antibacterial, antimitotic, antisepticise, and antiviral properties, due to the presence of aldehydes and phenols, for instance carvacrol, eugenol, and thymol (31). Among them, eugenol (C 10 H 12 O 2 ) is the main active phenolic compound present in the clove essential oil (32), which shows strong antibacterial activity against a wide range of Gram negative (G-) bacteria, including E. coli, Salmonella typhimurium, Pseudomonas aeruginosa, and also Gram positive (G+) bacteria, including Staphylococcus aureus (S. aureus) and Listeria monocytogenes (L. monocytogenes) (33,34). The action of essential oils against bacteria is based on interfering chemically with the synthesis or function of principal components of bacteria as well as blocking their antimicrobial resistance mechanisms.…”

“…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.…”
