Shelf Life Extension and Improvement of the Nutritional Value of Fish Fillets through Osmotic Treatment Based on the Sustainable Use of Distillation By-Products.

The objective of this work is the comparative study of different osmotic treatments at 37 °C on the quality and shelf life of chilled sea bass fillets. Fish fillets were treated using osmotic solutions consisting of oligofructose (40%-50%-60%) and 5% NaCl with (BP/OT) and without (OT) former antioxidant enrichment by using distillation by-products. Water activity decreased to approximately 0.
