Nanofibercontrol in beef with mononucleosis.

Electrostatic spinning method is an effective means to prepare micro-nanoscale continuous fibers, its unique advantage is that the preparation of fiber film than the surface area, small pores and high porosity, not only similar to the structure of the extracellular matrix, but also can load drugs, so in the biomedical field has a wide range of applications. Lin Lin, of the School of Food and Bioengineering at Jiangsu University,
, designed electrostatic spinning gelatin-glycerin-polylysine nanofibers to improve the mechanical properties of nanofibers and extend food preservation performance.
by analyzing the physical properties of electrostatic spinning solutions and nanofibers, gelatin: glycerin: the optimal ratio of glycerides-polylysine is 25:6:10 (m/V/V).
added glycerin, the tensile strength of the nanofibers reached (1.63 x 0.04) MPa.
observations of Fourier's transformation infrared spectroscopy, scanning electron mirror and atomic force microscope, the nanofibers were prepared in a uniform diameter of about 204 nm.
thermal reanalysis and differential scanning heat analysis results show that the thermal stability of nanofibers is stronger than pure components.
finally, the beef storage experiment using nanofibers showed that the nanofibers had significant antibacterial activity on mononucleosis in beef during the storage of 10 d and 12 degrees C, and had no effect on the color and sensory properties of beef.
, electro-spinning gelatin-glycerin-polylysine nanofibers can be used as an ideal packaging material in the food industry.
