Example Embodiment

[0034] Example 1

[0035] (1) Cut 50kg catfish into 2~3cm pieces of fish, add 2.50kg of sea salt (the weight ratio of fish salt is 20:1), mix well, and ferment at 30°C for 1 day, which is the early low-salt insulated fermentation;

[0036] (2) After 1 day of heat preservation and fermentation, add 14.17kg of sea salt (the weight ratio of fish salt is 3:1 at this time), mix well, and continue to ferment for 6 months under natural conditions (25±5°C), stirring once every 5 days , Is the mid-term high-salt natural fermentation;

[0037] (3) After 6 months of fermentation, heat preservation and fermentation at 40°C for 5 days to promote the formation of its color and flavor, for the later high-salt heat preservation fermentation;

[0038] (4) After 5 days of heat preservation and fermentation in the later stage, the fermented fish sauce is obtained by filtration and packaging.

[0039] After fermentation, the total soluble nitrogen, amino acid nitrogen, free amino acid content and pro...

[0040] Example 2

[0041] (1) Cut 50 kg of blue trevally into pieces of fish with a length and width of about 2 to 3 cm, add 12.5 kg of sea salt (the weight ratio of fish to salt is 4:1), mix well, and ferment at 60°C for 3 days, which is low in the early stage. Salt insulation fermentation;

[0042] (2) After 3 days of heat preservation and fermentation, add 12.5kg of sea salt (the weight ratio of fish salt is 2:1), continue to ferment for 12 months under natural conditions (25±5℃), and stir once every 10 days, which is the mid-term High-salt natural fermentation;

[0043] (3) After 12 months of fermentation, heat preservation and fermentation at 60°C for 15 days to promote the formation of its color and flavor, for the later high-salt heat preservation fermentation;

[0044] (4) After 15 days of heat preservation and fermentation in the later stage, the fermented fish sauce is obtained by filtration and packaging.

[0045] After fermentation, the total soluble nitrogen, amino ac...

[0046] Example 3

[0047] (1) Cut 50 kg of horse-noodle fish into pieces with a length of approximately 2 to 3 cm in width, add 10 kg of sea salt (the weight ratio of fish to salt is 5:1), mix well, and ferment at 60°C for 3 days, which is the early stage of low salt. Insulation and fermentation;

[0048] (2) After 3 days of heat preservation and fermentation, add 15kg of sea (the weight ratio of fish salt is 2:1), mix evenly, continue fermentation under natural conditions (25±5°C) for 18 months, and stir once every 5 days. Natural fermentation for mid-term high-salt;

[0049] (3) After 18 months of fermentation, keep it at 50°C for 10 days to promote its color and flavor formation, for the later high-salt insulation fermentation;

[0050] (4) Fermented fish sauce can be obtained by filtration and packaging after 10 days of heat preservation and fermentation in the later stage.

[0051] After fermentation, the total soluble nitrogen, amino acid nitrogen, free amino acid content an...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of rapid fermentation of fish sauce, in particular to a three-stage rapid fermentation method for fish sauce. Background technique [0002] Fish sauce, also known as fish sauce, is made of low-value marine fish as the main raw material, mixed with a certain proportion of sea salt (usually the weight ratio of fish and salt is 3:1-2:1), and the fish body itself is used Various enzymes such as cathepsin contained in it, and under the joint action of various microorganisms, decompose the protein, fat and other components of the raw fish, and ferment the liquid condiment with strong aroma and bright brown-red color. It is delicious and contains essential amino acids and taurine, as well as a variety of vitamins and trace elements. It is a traditional condiment loved by people in coastal areas of my country, Japan and Southeast Asian countries. [0003] The traditional fermentation process of fish sauce is to fully mix fish ...
