Abstract
The manufacture of composites with bioactive compounds represents a promising strategy for developing advanced materials in biomedical, food, and industrial applications. However, challenges such as stability, bioactivity retention, and controlled release hinder their effectiveness. Electrospinning emerges as a viable technique for encapsulating bioactive compounds, offering advantages such as high surface area, porosity, and gradual release, which are critical for maintaining the bioactivity of embedded compounds. Regarding bioactive composition, propolis has been highlighted as a potential source and has great potential as a biopolymer ingredient due to its antioxidant and antimicrobial properties. This study analyzed the composition and antioxidant activity of three commercial propolis extracts to select the most suitable extract for fiber composite production using zein and polyethylene oxide (PEO), both recognized as safe. The characterization of the electrospun fibers, including morphology, thermal properties, and antioxidant release, was conducted through various analytical techniques. The findings highlight the effectiveness of electrospinning for developing composite materials with bioactive compounds, paving the way for innovations in antioxidant technologies across multiple sectors.
