1. 21. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

   Författare :Mursalin Sajib; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; separation; silage; pilot-scale; lipid oxidation; Herring Clupea harengus ; protein hydrolysis; ensilaging; antioxidants; fish oil; valorization; by-products;

   Sammanfattning : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. LÄS MER
