Embodiment 1
[0047] The preparation method of a kind of fish protein peptide in embodiment 1 is basically as attached figure 1 As shown, the specific steps are as follows:
[0048] Raw material preparation steps: Prepare raw materials, raw materials include marine low-value small miscellaneous fish and aquatic product scraps, among which marine low-value small miscellaneous fish mainly include anchovy, shrimp, plucked headfish, crane needle fish and sea dragon fish; aquatic products Offals include fish heads, skins, tails and viscera;
[0049] Crushing step: mix the frozen low-value marine fish and aquatic product scraps with water, and the mass ratio of raw materials to water is 1:2, thaw the raw materials with water, and remove them after they are thawed and dispersed; The final raw material is put into the pulverizer, and the pulverizer is started to pulverize to form fish paste, and the mesh number of the fish paste is less than or equal to 10, and then the fish paste is placed in the...
Embodiment 2
[0058] The difference between embodiment 2 and embodiment 1 is that, as figure 2 As shown, in the microbial fermentation step, the fermentation time used is 36h. After this period of microbial fermentation and hydrolysis, the mass of fish protein peptides obtained from the hydrolysis of raw materials is 31% of the total mass of raw materials. Compared with Example 1 The degree of hydrolysis of raw materials has been improved.
Embodiment 3
[0060] The difference between embodiment 3 and embodiment 1 is that, as figure 2 As shown, in the microbial fermentation step, the fermentation time used is 30h. After this period of microbial fermentation and hydrolysis, the mass of fish protein peptides obtained from the hydrolysis of raw materials is 32% of the total mass of raw materials. Compared with Example 1 The degree of hydrolysis of raw materials has been improved.
