Abstract: The embedding, adsorption, organic solvent extraction, chemical covering and fermentation method for deodorizing the freshwater fish surimi were optimized respectively by orthogonal tests, with sensory evaluation and secaline content as analysis indexes. The combination of chemical covering and fermentation method shows the optimal deodorizing effect. And the optimal conditions are as follows: adding yeast 2.00%, 1% citric acid and 0.2% CaCl 2 at the same time, and then fermenting for 30 min at pH value 6.65 and temperature 35 ℃. The quality evaluation results of the surimi product deodorized accord with China national standard.

Key words: surimi product, fishy odor, deodorization
