Application of Natural Deodorant and Preservative in the Preservation of Fresh Grass Carp(Ctenopharyngodon idellus)

Deodorant effect of yellow wine,aqueous extraction of ginger,onion and garlic and yellow wine together with extraction of ginger,onion and garlic were compared in fresh grass carp deodorization,and the most effective deodorant,yellow wine together with extraction of ginger,onion and garlic was used to keep the preservation quality of grass carp fillets. The effects on preservation quality were determined by biochemical (pH,total volatile basic nitrogen,thiobarbituric acid),microbiological (total bacterial count) and sensory determinations during storage at 4℃. The extraction exhibited a beneficial effect on inhibiting lipid oxidation and bacterial growth in the fillets. Increases of pH,total volatile basic nitrogen,thiobarbituric acid and total bacterial count in fillets during storage were significantly reduced by the extraction.
