Marine life is not only one of the important food sources for human beings, but also contains many unique physiologically active substances. It is a treasure house of resources to be developed and utilized in human survival and development. So far, there are more than a thousand types of marine gods that have been studied and utilized, covering almost all categories, including algae, crustaceans, shellfish, jellyfish, hemichordates, and echinoderms. , puffer fish, sharks and fatty fish and other marine life.

Chitin is widely distributed in nature and is the second largest type of organic resource on the earth after cellulose. Chitin and its derivatives are nitrogen-containing polysaccharides, natural bioactive substances, and are widely used in many fields such as industry, agriculture, medicine, food, environmental protection, chemical industry, and national defense.

There are more than 20,000 crustaceans living in the ocean. Shrimp and crab shell waste is the main raw material for the industrial production of chitin and its derivatives. Coexisting with the shell waste are proteins, calcium carbonate, pigments and a small amount of fat. These coexisting substances can also be comprehensively utilized and processed into a variety of different products.

Fish sperm is a kind of reproductive cell that exists in the testes of male fish. Nucleic acid and protein are one of its important components. Because it contains more basic amino acids such as arginine and , it has a certain fishy smell and is generally discarded as waste in aquatic product processing. With the advancement of technology and in-depth research, people have found that both nucleic acids and protamine have certain nutrients and functionality, and are active substances that can be reused.

Due to the special chemical composition and structure of algae organisms, it has become an important resource for the isolation and extraction of marine biological active substances and the production of functional foods.

Xunyu Note: Although active substances have many benefits, they should be consumed in moderation.
