Abstract

This study investigated the use of various solvents to improve the encapsulation efficiency and preserve the bioactivity of resveratrol, addressing the challenge of encapsulating hydrophobic polyphenols. Nanofiber films composed of gelatin, carboxymethyl cellulose, and resveratrol were fabricated by an electrospinning technique. The incorporation of an acetic acid/ethanol mixed solution augmented the solubility of resveratrol, intensified its interaction with gelatin, and elevated its encapsulation efficiency. The diameter of the nanofibers grew from 111 ± 12.32 nm to 287 ± 10.65 nm. The antioxidant activity augmented by around 14%, whilst the antibacterial activity enhanced by about 11%. The spoilage rate of strawberry was reduced significantly by using electrospun nanofiber films containing an acetic acid/ethanol solvent mixture. The weight loss at day 6 was reduced by 50%. This research offers theoretical insights into the advancement of effective and stable active packaging materials.
