Embodiment 1

[0036] A method for recycling aquatic product processing leftovers, comprising the following steps:

[0037](1) Chop the leftovers of red fish, crush them with a beater, add water and add sweet potato skins, wheat flour, and corn husks, based on the weight of sardine leftovers, the amount of water added is 35%, and the amount of sweet potato skins added is 2.5%, the addition amount of wheat flour is 0.5%, the addition amount of corn bran is 2%, and then treated in water bath at 60°C for 30min, and sterilized at 121°C for 30min to obtain the fermentation substrate;

[0038] (2) Add 7.5% of the weight of the fermentation substrate in an organic solution (sterilized at 121°C for 15 minutes), wherein the content of glucose in the organic solution is 150g / L, β-hydroxy-β-methylbutyrate calcium The content is 25g / L, and then the staged fermentation method is adopted; the shaking table speed is 140r / min, based on the weight of the fermentation substrate, the fermentation substrate is ...

Embodiment 2

[0042] A method for recycling aquatic product processing leftovers, other steps are the same as in Example 1, and the difference from Example 1 is:

[0043] In step (1), chop the leftovers of red fish, crush them with a beater, add water and add sweet potato skins, wheat flour, and corn husks, based on the weight of sardine leftovers, the amount of water added is 40%, and the amount of sweet potato skins The addition amount was 1.5%, the addition amount of wheat flour was 1.5%, and the addition amount of corn bran was 2.5%, and then treated in a water bath at 60°C for 30 minutes, and sterilized at 121°C for 30 minutes to obtain a fermentation substrate.

Embodiment 3

[0045] A method for recycling aquatic product processing leftovers, other steps are the same as in Example 1, and the difference from Example 1 is:

[0046] In step (2), add 7.5% of the weight of the fermentation substrate in an organic solution (sterilized at 121°C for 15 minutes), wherein the content of glucose in the organic solution is 200g / L, β-hydroxy-β-methylbutyl The content of calcium acid calcium is 45g / L, adopts staged fermentation mode then; Wherein the rotating speed of shaker is 150r / min, by fermentation substrate weight, first inoculate 5.5% Clostridium butyricum culture liquid in fermentation substrate, in 37 It was fermented at ℃ for 6h, then inoculated with 4.5% Pseudomonas stutzeri culture solution, and fermented at 32°C for 48h to obtain the product.

Abstract

The invention discloses a recycling method for aquatic product processing leftovers. Belongs to the technical field of aquatic product processing. The method comprises the following steps: (1) chopping aquatic product processing leftovers, adding water for water bath treatment, and sterilizing to obtain a fermentation substrate; (2) adding an organic solution into the fermentation substrate, and inoculating a strain culture solution for fermentation culture; the strain culture solutions are respectively a clostridium butyricum culture solution and a pseudomonas stutzeri culture solution. The obtained fermentation product has high protein content, total amino acid content, unsaturated fatty acid content and non-protein nitrogen content.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a method for recycling aquatic product processing leftovers. Background technique [0002] my country is a large fishery country, and at the same time, my country is also the main base for processing trade of aquatic products in the world. During the processing of aquatic products, 20%-40% of waste (fish head, viscera, fish skin, fish bones, etc.) will be generated. These leftovers are rich in protein, fat, minerals, etc. If they are not utilized, it will cause a great waste of resources. Therefore, making full use of fish processing waste can not only increase the added value of fish products, but also has important practical significance in reducing the discharge of pollutants in the processing industry and protecting the environment. [0003] The disposal of leftovers is a common problem in aquatic product processing enterprises. Taking the mo...
