Abstract

The present invention discloses a nanocomposite fiber co-loaded with probiotics and antioxidants, wherein polyvinyl alcohol is dissolved in sterile deionized water to obtain a polyvinyl alcohol spinning solution; a natural antioxidant is added to the polyvinyl alcohol spinning solution, and the solution is stirred to obtain a polyvinyl alcohol / antioxidant spinning solution; a probiotic resuspension is added to the polyvinyl alcohol / antioxidant spinning solution, and the solution is stirred to obtain a polyvinyl alcohol / antioxidant / probiotic spinning solution; and the obtained spinning solution is electrostatically spun to prepare a functional nanofiber film co-loaded with probiotics and antioxidants. The nanofiber provided by the present invention can improve the survival rate of probiotics and protect the biological activity of antioxidants. At the same time, the addition of probiotics and antioxidants greatly improves the thermal stability and antioxidant properties of the functional nanofiber, and has the potential to be developed in the application of functional materials.
