“…This result and those previously reported [17,40,41] justify the interest in neem oil extracts as an active additive for obtaining bioactive films. According to the lack of notable antifungal activity of the rest of tested extracts, active films were formulated with neem oil and with oregano essential oil with proved antimicrobial activity [19,22]. …”

“…Films with the highest content of neem oil (S-PVA-2NO) reached the equilibrium value after 1 storage week. The different behavior of the films could be related with the specific interactions between the oil components and the matrix depending on the concentration [19,23]. Oil components could be linked to hydroxyl groups available in starch and PVA limiting polymer–water interactions, by hydrogen bonding, thus resulting in a decrease of the film moisturizing rate [43].…”

“…They are constituted by hydrophobic, volatile compounds with low molecular weight [18]. Among them, the oregano essential oil is one of the most effective antimicrobial oils and its active properties have been demonstrated in numerous studies [19,20,21]. These have been mainly attributed to carvacrol, thymol, γ-therpinene and p-cymene [22,23,24].…”

In this work, active films based on starch and PVA (S:PVA ratio of 2:1) were developed by incorporating neem (NO) and oregano essential oils (OEO). First, a screening of the antifungal effectiveness of different natural extracts (echinacea, horsetail extract, liquid smoke and neem seed oil) against two fungus (P. expansum and A. niger) was carried out. The effect of NO and OEO incorporation on the films’ physical and antimicrobial properties was analyzed. Only composite films containing OEO exhibited antibacterial and antifungal activity. Antibacterial activity occurred at low OEO concentration (6.7%), while antifungal effect required higher doses of OEO in the films. Incorporation of oils did not notably affect the water sorption capacity and water vapor barrier properties of S-PVA films, but reduced their transparency and gloss, especially at the highest concentrations. The mechanical response of the S-PVA films was also negatively affected by oil incorporation but this was only relevant at the highest oil ratio (22%). S-PVA films with 6.7% of OEO exhibited the best physical properties, without significant differences with respect to the S-PVA matrix, while exhibiting antibacterial activity. Thus, the use of OEO as a natural antimicrobial incorporated into starch-PVA films represents a good and novel alternative in food packaging applications.

“…Of the essential oils, oregano has been found to be one of the most effective against microbial growth, as demonstrated in numerous studies (Aguirre et al, 2013;Emiroǧlu et al, 2010;Zivanovic et al, 2005). Carvacrol, thymol, γ-therpinene and p-cymene are its principal constituents (Benavides et al, 2012;Jouki et al, 2014;Kuorwel et al, 2011;Sadaka et al, 2014;Sánchez-González et al, 2011b) and the antimicrobial activity is I.…”

“…The antimicrobial effect of EOs against bacteria has been extensively studied and reported (Smith-Palmer et al, 1998;Sivakumar & BautistaBaños, 2014;Rivera Calo et al, 2015). Gram-positive bacteria have been reported to be slightly more sensitive to EOs than Gram-negative (Aguirre et al, 2013;Corrales et al, 2014;Martucci et al, 2015;Smith-Palmer et al, 2001). This difference is related to the presence of an additional, relatively impermeable, outer membrane surrounding the cell wall in Gram-negative bacteria, which restricts the diffusion of hydrophobic compounds through its lipopolysaccharide covering Sánchez-González et al, 2011b).…”
