Abstract: The experimental results in this study showed that contents of protein and fat in sturgeon muscle are higher, and content of Glu is the highest among 17 amino acid, but that of Cys is the lowest. Essential amino acid composition is higher than adult requirement pattern of WHO. The fat, which is critical to flavor of dried fish floss, can be removed by 90% effectively by extraction method. The best formula of dried sturgeon floss is salt 1.5%, sugar 2.5%, ginger sauce 5%, yellow wine 2.5% , sauce 0.5%, monosodium glutamate 1% and peanut oil 3%.
