Emulsion-coaxial electrospinning: The role of zein as a shell layer in multicore-shell structured nanofibers for bioactive delivery.

Summary: Imagine a microscopic sandwich wrapper designed to keep food fresh and healthy. Scientists have developed a new way to make ultra-thin fibers using a "multicore-shell" technique. Think of it like a microscopic cable: the inner core is made of gelatin holding a healthy ingredient called curcumin (the active compound in turmeric), while the outer shell is made of zein, a protein found in corn. This corn-protein shell acts like a tough shield, making the fibers stronger and preventing the curcumin from washing away too quickly. The result is a smart material that releases its bacteria-fighting power slowly over time, making it a promising technology for advanced food packaging or delivering nutrients.
