Abstract
The invention discloses a preparation method of a spirulina antibacterial peptide composite membrane. The preparation method comprises the following steps: carrying out enzymolysis on spirulina powderby neutral protease to obtain spirulina antibacterial peptide, carrying out low-vacuum variable-frequency ultrasonic mixing on the spirulina antibacterial peptide, nano titanium dioxide, sodium alginate and the like, and drying to obtain the spirulina antibacterial peptide composite membrane. The prepared composite membrane is uniform in thickness, smooth in surface, free of obvious bubbles and good in antibacterial property, the tensile property of the composite membrane is greatly improved, and the composite membrane can be used as a packaging material.
