Investigation of physical, antioxidant, and antimicrobial properties of chitosan film with cinnamon affected by oleic acid showed that the presence of oleic acid increased the surface area and dispersion of the particles in the film formation and helped to preserve the film during drying. Water vapor permeability was greatly reduced in chitosan films containing oleic acid compared to the film containing cinnamon alone. The results showed that the cinnamon-containing film showed good antioxidant and antifungal effects (Perdones et al., 2014). In addition, the physical and antibacterial properties of alginate film with cinnamon and soy oil were investigated and it was found that the presence of cinnamon oil improved uniformity and transparency of film, as well as increasing elasticity and reducing water vapor permeability. Soy oil also helped to improve the antibacterial effect of film (Zhang et al., 2015).

Packer and Luz (2007) observed a fungistatic activity for the Rosmarinus officinalis L. essential oil through the solid medium diffusion technique, identifying inhibition halos greater than 60 mm. The Cinnamomum cassia essential oil, together with 74 samples from other natural products, was evaluated against Aspergillus niger using the agar diffusion technique, and a 40 mm inhibition halo value was obtained with this essential oil against the fungus (Pawar and Thaker 2006). Nuryastuti et al. (2009) observed that the cinnamon essential oil possesses antimicrobial activity against clinical S. epidermidis planktonic and biofilm cultures, including those with gentamicin resistance.

A PSA system produced from a mixture of Natural rubber (NR), cinnamon oil (CO) and xyloglucan(XG) by the help of two roll mixer was found to be suitable for food packaging applications (Figure 9). They could be applied on various packaging materials like nylon film, aluminium foil, kraft paper, polypropylene films etc. Peel strength values and shear strength of the prepared NR-CO/PSA with all the different types of substrates were found to be in the range of 0.24 × 104–9.50 × 104 N/m2 and 0.03 × 102–5.64 × 102 N/m, respectively. Xyloglucan was found to play the role of a tack enhancer which was evident from the results as peel strength was found to increases with increase in XG content. Cinnamon oil was incorporated due to its anti-microbial properties and is known to help in prolonging the shelf-life of packaged foods.[49]

The presence of curcumin in Curcuma longa is responsible for the antioxidant activity. The turmeric reduces the formation of peroxides and also increases the shelf life of oils [10]. Cinnamon has an effective antioxidant potential used in preventing oxidative stress. The flavonoid compounds present in the cinnamon is responsible for the antioxidant activity. The essential constituents present in cinnamon include cinnamaldehyde, eugenol, and linalool reducing lipid peroxidation. Due to the toxicity problems associated with synthetic antioxidants, there is an increasing trend in the research of natural antioxidants. Experimental results show that oxidation of palm oil is greatly reduced by the cinnamon extract and effectively replaces the synthetic antioxidants [11]. Cinnamon commonly referred to as Cinnamon cassia and Cinnamomum zeylanicum belongs to the Lauraceae family found all over the world. Cinnamon primarily used in aroma and essence industries for fragrance in foodstuffs, perfumes, and medicinal products contain resinous compounds with cinnamaldehyde, cinnamate, cinnamic acid and other essential oils [12]. In spite of its aroma and pungent activity, black pepper is important among the spice category. The ethanol extracts of black pepper have high antioxidant and radical scavenging activity. The antioxidant activity of black pepper can be attributed to the strong hydrogen donating ability, metal chelating ability and their effective scavenging activity of hydrogen peroxides and free radicals due to the presence of phenolic compounds in antioxidants [13]. Black pepper is known as Pipernigrum L., belongs to the family of Piperaceae traditionally used in Indian ayurvedic medicine, prevents oxidative stress [14].

Cinnamomum zeylanicum (cinnamon) is a plant characterized by high antioxidant activity which is used in traditional medicine (13). Additionally, cinnamon extract revealed effective reduction of the lipid oxidation of palm oil, thus, can be used instead of synthetic antioxidants (14). Cinnamon could be a source of natural antioxidant therapeutic agent which opens new window for the progress of science of food materials in the biomedical and health fields (15). However, there is evidence suggesting that despite cinnamon is safe, it might cause significant adverse effects in medicinal uses in case of increase in doses or period of use (16).
