An innovative approach for the production of bio-micro/nanostructures with high-value compounds from agricultural by-products was studied. This research aimed to valorize bioactive compounds existing in the by-products of the plants of (wild strawberry). The particle characteristics, morphology, size, release properties, and antioxidant activity of micro/nanostructures containing the extract of by-products of the plants of or quercetin (one of the main polyphenols in the plant) were analyzed.

- EGCG is a beneficial antioxidant and vitamin B12 is essential for health, but both can lose effectiveness during processing due to stability issues.
- Microencapsulation using a biological polymer called zein was explored to protect these compounds, with various concentrations tested via an electrospinning technique.
- The study found high encapsulation efficiency, particularly with 1% active substance and 30% zein, and the release profiles were best explained by the Weibull model during controlled release tests.
