In this study, carboxymethyl cellulose (CMC) films containing 1%, 2%, and 3% Chinese fir essential oil (CFEO) were prepared. The mechanical, optical, physical, microstructural, thermal stability and antimicrobial properties of the films were studied. A traditional steam distillation method was applied for CFEO extraction, in which 35 volatile components were identified. The research results showed that the CMC film mixed with 1% CFEO had the highest tensile strength (TS) and elongation at break (EB), whereas the flexibility was decreased under higher concentrations of CFEO. However, the film’s degree of transparency under controlled humidity did not decrease with an increase in CFEO concentration; thus, the sensory evaluation was not adversely effect. Furthermore, the thickness and the water solubility (WS) of film increased after the addition of CFEO. The thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) results indicated that the thermal stability of the CMC-CFEO films improved. Moreover, the composite films showed excellent inhibitory effects toward Gram-positive bacterias and Penicillium citrinum. The treatments of grapes with CMC + 1% CFEO resulted in the best properties during storage. CMC-CFEO film can be a candidate for food packaging due to its excellent performances.

Physicochemical Features

The current research presents the physicochemical, antioxidant, mechanical, and antimicrobial features of biocomposite films on the basis of carboxymethyl cellulose (CMC) combined with essential oil (EO) of Mentha pulegium (MEO) (1, 2, and 3% v/v). Adding EOs enhanced the penetrability of water vapor and the solubility of films in water, while decreased absorption of moisture and level of moisture. Incorporation of MEO enhanced opacity, total color differences, and whiteness index. Generally, adding MEO into the CMC biocomposite reduced considerably young modulus and tensile strength, while enhanced elongation at the composite films break ( p < 0.05). The films incorporating MEO had excellent total phenolic and antioxidant features; this impact was significantly developed when the MEO was enhanced. Films comprising MEO controlled the microorganism’s growth efficiently. Fourier-transform infrared spectroscopy was used to determine the physicochemical features of the films and the features of the films were corresponded to their microstructure, which was found using scanning electron microscopy.

<span class="fontstyle0">This research focused on the study of the capability of cinnamon essential oil as antibacterial<br />agent, when it is made as a microemulsion solution. The study occupied further research on<br />specific type, concentration, and amount of emulsifier needed to make the cinnamon essential<br />oil miscible in water without causing destruction in its antibacterial activity. Four different<br />emulsifiers were tested, namely Tween 20, Tween 80, soya lechitin, and carboxymethyl cellulose<br />(CMC) to stabilize the essential oil in water. The emulsifiers were used at 2% w/w, while the<br />essential oil concentrations were varied at 0.5%, 1%, and 1.5%. In this study, the antibacterial<br />activity of the microemulsion solution of cinnamon essential oil was tested against two types of<br />pathogenic bacteria commonly found in foods, namely Staphylococcus aureus and Escherichia<br />coli. Among the four types of emulsifiers, which are used, CMC showed the best results as an<br />emulsifier. The results of this study indicated that microemulsion solution has antibacterial<br />activity best is a combination between the CMC and the essential oil of cinnamon</span>
