“…For the CH/SC film, the absorption peaks dominated by the amide I band of CH at 1640 cm − 1 and 1560 cm − 1 decreased to 1635 cm − 1 and 1538 cm − 1 , confirming that there were electrostatic interactions between the amino groups of CH and the negatively charged carboxyl groups of the CS in the complex films (Volpe et al, 2017;Khwaldia, Basta, Aloui & El-Saied, 2014). Regarding REO, an evident peak at 1744 cm − 1 was related to a keto group of camphor, and two peaks at 1214 cm − 1 and 984 cm − 1 were related to the epoxy ring of 1.8-cineole, as confirmed by Stramarkou, Oikonomopoulou, Missirli, Thanassoulia, and Krokida (2020).…”

Characterization and Antibacterial Activity of Encapsulated Rosemary Essential Oil within Amylose Nanostructures as a Natural Antimicrobial in Food Applications

Rosemary essential oil (REO) is a natural phenolic compound with high antimicrobial activity. However, its application is limited due to the poor solubility in water, instability, and high volatility. In this study, REO is incorporated into the high amylose corn starch (HACS) nanostructures by inclusion complexation. The characterization of the obtained nanostructures is done by SEM, TGA, FTIR, and XRD. Encapsulation efficiency, loading capacity, stability, release, and antibacterial activity of encapsulated REO are analyzed. The nanostructures show spherical nanoparticles with an average size lower than 200 nm. The results of XRD and FTIR confirm the incorporation of REO into the amylose nanostructures. Thermogravimetric analysis indicates that the inclusion complex of REO and HACS increases the thermal stability of REO significantly. The solubility and antibacterial activity of REO are enhanced after complexation with amylose nanostructures. Minimum inhibitory concentration (MIC) of free REO is 3.52 mg mL−1 or 0.39% v/v and for encapsulated REO is decreased to 2.5 mg mL−1. The results suggest that HACS can be used as a potential carrier for sensitive and hydrophobic compounds to enhance their application in the pharmaceutical and food industries.

“…The peak at 987 cm −1 and 1217 cm −1 was due to the ether function of an epoxy ring of 1, 8-cineole. The peak at 1082 cm −1 was related to the asymmetric stretching of the C-O bond [52,53]. The FTIR spectrum of nisin showed that the peak at 3284 cm −1 was due to the axial tensile vibration of O-H and N-H.…”

Edible nanoparticles containing antibacterial agents are one of the effective strategies to control foodborne diseases. Herein, novel ternary nanoparticles (TNP) were prepared from rosemary essential oil (REO), nisin and Lycium barbarum polysaccharides (LBP) through hydrophobic and electrostatic interaction. The average particle size of TNP was 211.5 nm, and its encapsulation efficiency reached 86.6%. After the addition of LBP, the physical stability, thermal stability and storage stability of TNP were significantly improved. In vitro, compared with the control group, the population of S. aureus and E. coli O157:H7 in the TNP-treated group was reduced by 2.386 log CFU/mL and 1.966 log CFU/mL, respectively, on the fifth day. The free radical scavenging rate of TNP was 63.15%. The application of TNP on beef presented favorable preservation effects without affecting its color and texture. Therefore, the synthesis strategy of TNP has important reference significance for the research and development of new food antibacterial agents.
