Embodiment 1
[0074] S1. Pretreating the biological raw material;
[0075] The biological raw material is cowhide; the pretreatment includes the following steps: cut the cowhide into pieces, rinse with clean water after cutting and drain, then soak in ethanol for 2 hours, and soak in 1mol / L sodium hydroxide for 2 hours after draining, and then Drain and rinse with clean water.
[0076] S2. Slicing the biological raw material to obtain thin slices;
[0077] The diced cowhide is sliced, and the thickness of the thin slices obtained by slicing is 0.8mm, and the thin slices are sprayed with 3 wt% hydrogen peroxide aqueous solution.
[0078] S3. Put the slice under the condition of 60-70°C, and use ultraviolet light to irradiate the upper and lower surfaces of the slice at the same time; the heating time is 1h, and the ultraviolet light intensity is 300uw / cm 2 , the ultraviolet light is long-wave ultraviolet light with a wavelength of 320-400nm. The thermal denaturation of the flakes is carri...
