The invention discloses a method for three-stage type fast
fermentation of fish gravy. The method carries out
fermentation of fish gravy by three stages of insulating
fermentation with
low salt in early stage at the temperature of 40 to 60 DEG C according to the weight ratio of 20:1 to 4:1 of fish and salt, natural fermentation in middle stage and insulating fermentation with high salt in
late stage at the temperature of 40 to 60 DEG C according to the weight ratio of 3:1 to 2:1 of fish and salt; not only the increase of the content of total
soluble nitrogen,
amino acid nitrogen and free aminoacid thereof is faster, the content thereof exceeds national first-class fish gravy standard when carrying out fermentation for 15 days, and the
flavor, body state and color thereof are better afterhigh-salt insulation in the
late stage; and compared with the traditional method, the method can shorten the fermentation time of the fish gravy from 2 to 3 years to 1 to 1.5 years.
