Collagen is the most abundant structural protein in humans. Thanks to its properties, it is one of the most widely used biomaterials in health-related sectors. The industrial production of collagen mostly relies on its extraction from mammals. However, immune reactions triggering, zoonosis transmission risks, cultural and religious issues limited its use. In this perspective, in the last two decades marine organisms attracted interest as safe, abundant and alternative sources for collagen extraction. Every year fish processing industry discards account for about 70-85% of the total catch weight and raise significant environmental pollution. The possibility to valorize fish byproducts as collagen sources makes fish collagen eco-friendly and attractive in terms of profitability and cost effectiveness. Additionally, fish byproducts harvesting from eco-sustainable aquaponics systems allows to obtain fish biomass with controlled properties over time. In this work, the physical, chemical, structural and biological properties of type I collagen isolated from Nile Tilapia skin raised in a pilot aquaponic system were assessed and compared with those of a commercially available isoform.

Abstract
Collagen is the most abundant structural protein in humans. Thanks to its properties, it is one of the most widely used biomaterials in health-related sectors. The industrial production of collagen mostly relies on its extraction from mammals. However, immune reactions triggering, zoonosis transmission risks, cultural and religious issues limited its use. In this perspective, in the last two decades marine organisms attracted interest as safe, abundant and alternative sources for collagen extraction. Every year fish processing industry discards account for about 70-85% of the total catch weight and raise significant environmental pollution. The possibility to valorize fish byproducts as collagen sources makes fish collagen eco-friendly and attractive in terms of profitability and cost effectiveness. Additionally, fish byproducts harvesting from eco-sustainable aquaponics systems allows to obtain fish biomass with controlled properties over time. In this work, the physical, chemical, structural and biological properties of type I collagen isolated from Nile Tilapia skin raised in a pilot aquaponic system were assessed and compared with those of a commercially available isoform.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
