Preparation and Properties of BHT/HPβCD Inclusion Complex Nanofibers
Dibutylhydroxytoluene is a food additive that meets national safety standards and has good antioxidant properties,but its poor water solubility limits its application.Dibutylhydroxytoluene/hydroxypropyl-β-cyclodextrin(BHT/HPβCD)inclusion complex nanofibers were prepared by electrospinning technology and characterized by Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),scanning electron microscope(SEM),thermo-gravimetric analysis(TGA),phase solubility experiments and OH radical scavenging experiments.The FT-IR,XRD,and SEM tests showed that uniform and smooth BHT/HPβCD inclusion complex nanofibers were formed.TGA results showed that the temperature at which the inclusion complex nanofibers began to decompose was higher than the temperature at which the BHT raw material begins to decompose,and the BHT/HPβCD inclusion complex nanofibers could effectively improve the thermal stability of BHT.The results of phase solubility showed that the formation of BHT/HPβCD inclusion complex nanofibers could significantly increase the water solubility of BHT,and the OH radical scavenging activity of BHT/HPβCD inclusion complex nanofibers was higher than that of BHT raw material,showing good antioxidant activity.
