In the framework of the REFISHEIN project, researchers from Leitat and LEF Ingenieros created a method that extracts, purifies, and recovers the protein present in the stickwater thanks to a hybrid process.<\/p>\n
Laura P\u00e9rez Meg\u00edas, Sandra Balsells, S\u00edlvia Junc\u00e0, Camilo Aveda\u00f1o, Edxon Licon-Bernal, Xavier Sim\u00f3n Font, Montse Jorba, and Julia Garc\u00eda-Monta\u00f1o, from Leitat and LEF Ingenieros, both entities from Barcelona (Spain), published a technical paper entitled \u00abValorization of the protein fraction of the stickwater of the fishmeal production process through enzymatic hydrolysis and ceramic filtration.\u00bb AZ Ingenier\u00eda (Spain) and M\u00e1quinas Ltda (Chile) also participated in the project.<\/p>\n
The analysis focuses on the fact that during the production of several foods and food products in the fishing sector, an inevitable loss of protein occurs due to the production of fishmeal. Most of these losses of valuable products are found in water, for example, when dehydration is carried out by centrifugation. The aqueous by-product in these facilities is known as stickwater and may contain 8-10% solids with an important protein content.<\/p>\n
\u00abDue to this protein content, stickwater is of particular importance from a technical, environmental, and economic point of view. In addition, the wastewater produced by the fishing industry is the main source of pollution on the seabed and seawater when it spills into the ocean where these types of industrial plants are established. Therefore, it is important to create a viable route to treat the stickwater correctly and, in turn, to recover valuable substances present in it,\u00bb argue the signatories of the technical article.<\/p>\n
