Preparation And Research On An Antioxidant Phycocyanin/Collagen Composite Hydrogel
Keywords
Phycocyanin, Collagen, Composite Hydrogel, Antioxidant
Abstract
Type I collagen extracted from tilapia skin was mixed with different concentrations of phycocyanin, and a composite hydrogel was prepared using the self-assembly properties of collagen. The air permeability, micromorphology, and infrared spectrum of the composite hydrogel were investigated. , swelling rate and antioxidant properties. The results showed that the air permeability of the composite hydrogel increased significantly. As the phycocyanin content increased, the micromorphological pores and swelling properties of the hydrogel increased. The infrared spectrum showed that the preparation method did not destroy the characteristic absorption peaks of the two proteins. In the antioxidant experiment, the composite hydrogel has DPPH free radical and hydroxyl radical scavenging ability, showing excellent antioxidant ability.
