Natural Antioxidants in Salmon Aquaculture: Processing Fate, Tissue Deposition, and Oxidative Protection.

ABSTRACT: The use of natural antioxidants (NAOXs) to prevent feed oxidation and reduce oxidative stress in fish is gaining momentum in the aquafeed industry. As sustainable alternatives to synthetic antioxidants like ethoxyquin (banned) and butylated hydroxytoluene (BHT)/butylated hydroxyanisole (BHA) (under scrutiny), NAOX (particularly polyphenols) require assessment for their stability during feed production and their biological effects on fish. This study followed four natural polyphenols (NPs) in a plant-based ingredient, which was then incorporated into a standard feed. The polyphenols were tracked through various processing stages (ingredients, diet mix, extrusion, drying, and storage) and in fish tissues (liver and muscle) using liquid chromatography mass spectrometry.
