Preparation and Characterization of Ginger Essential Oil Microcapsule Composite Films

Abstract

New food packaging has shown research significance in the face of increasing demand for high-quality foods and growing attention paid to food safety. In this study, ginger essential oil microcapsule composite films were prepared by combining microcapsules prepared by a complex coacervation method with gelatin films, and the mechanical properties and active functions of the composite films were analyzed. Fourier-transform infrared spectroscopy and differential scanning calorimetry confirmed the successful encapsulation of ginger essential oil. The scanning electron microscopy of the composite films showed the microcapsules and gelatin film matrix were highly compatible. During the entire storage period, the antioxidant capacity of the ginger essential oil microcapsule films weakened more slowly than ginger essential oil microcapsules and could be maintained at a relatively high level for a long time. The microcapsule films had excellent inhibitory effects on Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. Therefore, the direct addition of microcapsules to a film matrix can broaden the application range of microcapsules and increase the duration of the release of active ingredients. Ginger essential oil microcapsule films are potential biodegradable food packaging films with long-lasting activity.

Preparation and antibacterial and antioxidant ability of β‐cyclodextrin complexes of vaporized Illicium verum essential oil

“…Compared with 10 min, the reducing power of β-CD-IvEO-ICs increased substantially in 1 h reaction time, which could be due to the controlled release of IvEO in inclusion complexes, resulting in stronger antioxidative activities as the reaction time was extended. This phenomenon was in line with those observed in studies (Khatibi et al, 2021;Wang et al, 2021).…”

“…Conversely, PEO in the PEOM must be penetrated the wall of GE, and gradual release under the same conditions. The results of comparison showed that the antioxidant activity of PEOM was found to be more sustainable than PEO, results consistent with those of Wang et al ( 32 ).…”

“…Sample pretreatment of PEOM was carried out as described by Wang et al ( 32 ). Briefly, antioxidant capacity and antibacterial activity were measured every 1 day, during 5 days.…”

“…The compositions, structures, and functional groups of essential oils play a role in determining their antibacterial activity [11] . However, it is known that the effectiveness of the GEO as an antibacterial activity is poor due to its instability in the environment, high volatility, and susceptibility to temperature, humidity, or oxidation, thus limiting its application [12] …”
