Brazilian Red loaded Degradable Electrospun Film: Activity and Adjustable Release Study for Intelligent Food Packaging

Research Overview: According to the study published in Volume 58 of Food Packaging and Shelf Life (December 2026), authors Q. Litke, F. Jonidi Shariatzadeh, D.B. Levin, and S. Liu reported a biodegradable electrospun film loaded with Brazil red pigment, which has adjustable release behavior and is targeted for active and intelligent food packaging applications. This study combines natural active ingredients with electrospinning processing, providing a new material solution for the functionalization of packaging materials.

Materials and processing ideas

The study used electrospinning to prepare biodegradable fiber membranes and introduced Brazilian red pigment into the fiber system.

. Electrospun fiber membranes have a high specific surface area and a designable fiber structure, which provides a structural basis for the loading and release regulation of active substances. In research, “adjustable release” is the core performance indicator, which means that the release rate or amount of active ingredients can be adjusted through material and process design, rather than a one-time rapid release. From the perspective of packaging materials, this type of film involves two directions simultaneously: one is active packaging, which exerts antioxidant and other effects by releasing active ingredients; The second is intelligent packaging, which utilizes the response characteristics of active ingredients to transmit information. The research title juxtaposes the two, indicating that the film is positioned as a packaging material system with both activity and intelligent potential.

The significance of this study for the polymer additive industry

The inspiration for the field of packaging materials lies in the synergistic design of biodegradable substrates and functional additives.

. Electrospun films require system stability during processing, and packaging materials may face thermal oxidative aging risks during spinning, film formation, and subsequent storage stages. The selection of processing stabilization aids such as antioxidants can affect the quality of fiber film formation and the retention of active ingredients. For applications targeting food contact, the migration behavior, residue levels, and compliance with food contact requirements of additives and active ingredients must be considered simultaneously in formulation design. Secondly, the design concept of adjustable release has reference value for controlling the release of additives. The migration and release of antioxidants and other additives in packaging materials also affect shelf life performance. The regulation of release rate by electrospun fiber structure can provide reference for the slow-release design of additives in packaging systems. In addition, the compatibility between biodegradable membranes and recycled material systems is also worth paying attention to: with the increasing proportion of recycled materials, how to blend functional membrane materials with recycled materials and how to adapt to stable processing systems are questions that need to be answered for industrial implementation.
