Description

Garlicin-loaded antibacterial packaging film and preparation method thereof
Technical Field
The invention belongs to the technical field of active food packaging materials, and particularly relates to an allicin-loaded antibacterial packaging film and a preparation method thereof.
Background
With consumers focusing more and more on the quality, safety and freshness of food products, research on active food packaging has been rapidly progressing. The unique characteristic of the active package is that natural antibacterial factors (such as cinnamon essential oil, eugenol and the like) obtained by adding functional active factors (such as antibacterial agents) are usually nontoxic and have strong antibacterial activity, and a good choice is provided for the development of the antibacterial active package.
Allicin is an organic sulfur compound extracted from garlic bulbs. It has strong antibacterial effect, and can inhibit various gram-positive and gram-negative bacteria at very low concentration. Allicin can interact with thiols such as glutathione and L-cysteine in bacterial cells to form S-allylmercaptoglutathione and S-allylmercaptocysteine, respectively, potentially leading to detrimental structural changes in bacterial proteins. However, there is no report on the preparation of antibacterial food packaging films using allicin.
At present, solvent casting, extrusion, thermoforming and other methods have been applied to the encapsulation of active factors to develop active packaging. However, the commonly used methods involve high temperature/high pressure processes, which may destroy the activity of the heat-sensitive active factors. Electrospinning has been recognized as a convenient and versatile method of encapsulating sensitive bioactive factors. It is based on the preparation of nanofibers by electric forces, can be performed at room temperature, and allows efficient encapsulation and functional retention of active factors. In addition, the electrospun nanofiber membrane has a large specific surface area and extremely high porosity, is favorable for enlarging the contact area with the surface of food, and also is favorable for realizing high surface activity due to the nanometer size effect, thereby being favorable for packaging active food.
Polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), polyethylene oxide (PEO), and the like have excellent spinnability and high safety, and are often used for food packaging by electrospinning alone or blending with food materials. However, they are highly hydrophilic and poorly water stable, and are not suitable for use in high moisture content food samples. Currently, cross-linking of electrospun nanofiber membranes is a common approach to solving this problem. However, most cross-linking agents are harmful. For example, Glutaraldehyde (GA) is a common cross-linking agent, has high toxicity, easily penetrates into food samples of packaging materials, and is harmful to food safety and consumer health. Some researchers also used genipin as a non-toxic cross-linking agent, but it is expensive and not suitable for food packaging. Therefore, there is a need to develop safe and economical methods to make these hydrophilic materials more suitable for food packaging. In the research, under the condition of not using any toxic and harmful toxic solvent (only using ethanol as a solvent) and a cross-linking agent, the hydrophilic PVP nano-fiber membrane is successfully converted into hydrophobicity by adding the nontoxic polymer PVB for blending electrostatic spinning. In addition, the PVP/PVB nanofiber membrane prepared has larger water absorption capacity due to the PVP.
The PVP/PVB-Allicin (PB64-A) nanofiber membrane is prepared by an electrostatic spinning method, and the prepared fiber membrane has broad-spectrum antibacterial activity, good hydrophobicity, stronger water absorption stability and good light blocking capability, has wide application prospect in the field of food active packaging materials, and is particularly suitable for meat foods.
