Fish gelatin: The novel potential applications

Fish gelatin is a class of biopolymers acquired from the hydrolysis of fish collagen, and it contains abundant amino acids for nutritive uses as dietary products. The natural characteristics of fish gelatin mean that fish gelatin products are relatively harmless to the body compared with clinical therapies and drugs. Thus, the dietary use of fish gelatin can potentially have excellent benefits for people with chronic diseases such as hypertension, osteoporosis, and diabetes. Moreover, researchers have found multiple routes for the administration of fish gelatin products such as external use or injection. In this review, we summarize the new usage of fish gelatin products and provide an update on the latest research on other properties and applications of fish gelatin. These new applications will provide multiple uses for fish gelatin products in the future, though further research is still needed.
