| titleOfInvention | Method for extracting fish collagen from fish skin |
| abstract | The invention provides a method for extracting fish collagen from fish skin. The method comprises the following steps: (1) extracting collagen: adding protease to the fish skin to carry out enzymolysis, then killing the protease to obtain a collagen crude extracting solution; (2) decolorizing: adding pure active carbon to the prepared collagen crude extracting solution from the step (1) while carrying out stirring, then carrying out decolorizing, deodorizing and filtering to obtain a collagen clear solution; (3) removing a heavy metal: carrying out absorbing for the resulting collagen clear solution from the step (2) through a resin for removing arsenic, then washing the resin for removing the arsenic through purified water and collecting eluent; (4) finishing the product: carrying out evaporating, condensing, spray drying for the resulting eluent from the step (3) to obtain the fish collagen having a molecular weight of 2000-3000 dalton. With the present invention, the process for the fish collagen is simple; product quality of the fish collagen is good; toxic and harmful reagents are not remained in the prepared fish collagen product; the heavy metal in deep sea fishes can be removed well so as to effectively control the product quality and provide high safety. |
