When we talk about fish, we tend to think of it only as food. Whole, in fillets, sliced or prepared; we consider it, mostly, human food. And even though that is true, there is also a fish by-products industry that reuses some of its parts.
In this article, we have already detailed the uses of the different fish by-products.
One is the skin. So, what about fish skin?
Large fish handling companies are forced to remove the skin for the customer’s convenience, but … what is done with this skin?
One of the most common uses is in the cosmetics and dietetics industry.Easy Fish Group
Fish skin, in general, and of some species in particular (Tilàpia, Panga, Cod, etc.), is a very important source of collagen. Collagen is a fibrous protein found mainly in the intercellular layers or connective tissues. It is used in biomedicine and cosmetics as a remedy for wounds and as a dietary supplement for the prevention and treatment of osteoarticular problems.
Through an industrial process, collagen is extracted from the skin through treatments. This collagen is used as a base to produce many cosmetic and dietary products. Moisturizers, food supplements, dressings, and a myriad of utilities make collagen a vital ingredient for this industry.
Chitosan, another element with many applications in biomedicine, dietetics, and agriculture, can also be obtained from flakes. Chitosan helps prevent clots, as well as protects the seeds of plants.
Another use of fish skins has appeared in recent years in the fashion industry. Cured and treated leathers are used to make bags or shoes. Although it is a very young business, its acceptance is growing every day and the revenues are getting more and more significant.
