I'm grinding the fish visceras to make it silage. Antioxidants are needed to prevent the oxidation of the fish due to its high degree of unsaturation. In this case, I'm using hydroquinone, C6H4(OH)2 . It's in crystal form. I'm confused how much of hydroquinone needed for 500g of fish silage. Do i need to make the hydroquinone in to liquid form? Could anyone help me in this?
Thanks in af advance.
You can dissolve hydroquinone in water and then add the solution to the homogenized viscera. Not much water is needed, so volume change is insignificant. I use an antioxidant mixture of BHA/BHT (1:1) added at a concentration of 200 mg/kg homogenized by-products and it works just fine. I do not know for hydroquinone though. You may have to look into that using different concentrations of the antioxidant.
