NUTRIENTS IN SALMON AND RED GROUPER FILLETS AS AFFECTED BY CHLORINE DIOXIDE (CLO2) TREATMENT

The effect of chlorine dioxide (ClO2) treatment on nutrients of seafoo d was studied using Atlantic salmon (Salmo salar) and red grouper (Epi nephelus morio) with five volumes (1:5, w/v) of aqueous ClO2 at 20, 40 , 100, and 200 ppm ClO2 in 3.5% brine for 5 min. Compared to nontreate d controls, treatment of salmon and red grouper with ClO2 solutions in brine did not significantly change the contents of protein, fat, mois ture, niacin, calcium, iron, phosphorus, or potassium. However, such t reatment with brine or ClO2 solutions in brine caused a significant re duction in thiamin content in both species, but only riboflavin was re duced significantly in red grouper, possibly due to the solubilization effect of salt on the vitamins.
