AB - Biological enzyme is a kind of substance, which can catalyze specific reaction. In our work, sericin
membranes are prepared under the catalysis of tyrosinase, which promoting protein molecules crosslinking
through tape casting method. Taking the water solubility of sericin membranes as the evaluation index,
the optimal preparation conditions are determined as follows: the dosage of tyrosinase 1000 U/g, the
reaction temperature 45 °C, for 90 min, 2% glycerol and drying temperature at 45 °C. The results of
infrared spectra indicate that the structure of amide I is changed in crosslinked sericin membranes. The
XPS results indicate the O atom content is increased in crosslinked sericin membrane. This verifies the
crosslinking of sericin protein by tyrosinase.
