The invention discloses a color-adjustable edible collagen membrane and a production method thereof. The method comprises the following steps: reacting animal collagens dissolved in an acetic acid solution with glutamine transaminase, removing bubbles, carrying out film formation drying to obtain a white transparent collagen membrane, immersing the white transparent collagen membrane in a buffer solution of colored tannin extract to carry out a reaction, flushing the obtained membrane with water after the reaction is finished, and drying the flushed membrane to obtain the color-adjustable edible collagen membrane. The collagen membrane has greatly improved tensile strength and various colors, and exogenous substances introduced in the cross-linking process are food levels, are natural andhave no pollution, so the collagen membrane can be used food packaging in various occasions as an environmentally-friendly packaging material to substitute plastics and paper.
