[0022] Example 1
[0023] Preparation of mixed lactic acid bacteria liquid: using MRS solid medium plates to activate low-temperature stored Bifidobacterium lactis and Lactobacillus acidophilus at 25°C. Inoculate the fermentation medium (each milliliter of medium containing 10 grams of sodium chloride, 15 grams of lactose, 30 grams of mackerel homogenate supernatant, 0.22 micron filter membrane filter sterilization) to cultivate first-level seeds and second-level seeds, The secondary seeds are cultivated to a pH less than 4.0, and the filtered fermentation medium is used to dilute the two bacterial liquids to a density of 10 7 cfu / mL, mix in equal volume before inoculation.
[0024] Fermentation of mackerel: Wash 5 kilograms of mackerel, remove the internal organs, head and tail, wash, and drain; add 500 grams of salt, mix well, and divide them into two equal portions, and place them in a crock pot. One part without adding starter, directly cover the tank, seal it, and ferment at ...

[0031] Example 2
[0032] Preparation of mixed lactic acid bacteria fermentation broth: using MRS solid medium plates to activate low-temperature stored Lactobacillus plantarum and Bifidobacterium lactis at 25°C. Inoculate the fermentation medium (each milliliter of medium containing 10 grams of sodium chloride, 20 grams of sucrose, 25 grams of small yellow croaker homogenate supernatant, 0.22 micron membrane filter sterilization) to cultivate first-level seeds and second-level seeds, second-level seeds Until the end of the culture to pH less than 4.0, use the filtered fermentation medium to dilute the two bacterial liquids to 10 7 cfu / mL, mixed with equal volume before inoculation as a compound starter.
[0033] Fermentation of small yellow croaker: Remove the internal organs and heads of 5 kg of small yellow croaker, wash and drain; add 500 grams of salt, mix well and place in a porcelain pot. Divide equally into three parts and place them in a crock pot. One part without addin...
