Embodiment 1

[0007] Embodiment 1. Get fresh low-value fish and shrimp and process according to the following processing steps: (1) remove impurity: fresh low-value fish and shrimp are removed impurity. (2) Degreasing: degreasing fresh low-value fish and shrimp from which impurities have been removed by cooking and pressing to obtain solid materials and oil-water mixtures. (3) Oil-water separation: The oil-water mixture obtained by degreasing is subjected to centrifugation to obtain oil and protein-containing turbid water, and the oil is recycled. (4) Pulverization: after mixing the turbid water containing protein and the solid material obtained after degreasing in a ratio of 0.8:1, pulverize into a slurry of 80-300 mesh (0.18-0.05mm). (5) Sterilization: Add known preservatives and antioxidants to the slurry, adjust the pH value between 6.5-8.0, pasteurize or maintain 10-30 minutes at 80-85°C for sterilization, and then cool to 35-60°C. (6) Enzymolysis: add compound protease according to ...

Embodiment 2

[0008] Embodiment 2. Get the edible part of the leftovers after the processing of fresh aquatic animals and process according to the following processing steps: (1) remove impurities: remove impurities from the edible parts of the leftovers after the processing of fresh aquatic animals; (2) Degreasing: degreasing the edible part of the processed waste of fresh aquatic animals from which impurities have been removed, and degreasing to obtain solid materials and oil-water mixture; (3) oil-water separation: centrifuging the oil-water mixture obtained by degreasing to obtain oil and protein-containing turbid water, oil recycling; (4) crushing: take the protein-containing turbid water and the solid material obtained after degreasing and mix them in a ratio of 2.0:1, and then grind them into 80-300 mesh (0.18-0.05mm ) of slurry. (5) Sterilization: Add known preservatives and antioxidants to the slurry, pasteurize or maintain at 80-85°C for 10-30 minutes to sterilize, then cool to 35...

Embodiment 3

[0009] Embodiment 3. Get the edible part mixture of fresh low-value fish and shrimp and the processed waste of aquatic animals, and process it into polypeptide paste or polypeptide powder according to the processing steps of Example 1.

Abstract

The biotechnological process of producing polypeptide and protein feed is superior to traditional fish meal producing process, which has high protein loss rate, high power consumption, high cost, serious pollution and other demerits. The present invention produces polypeptide paste, polypeptide powder, protein paste or protein powder with fresh low value fishes and shrimp and aquatic animal leftover and through the process including the steps of eliminating impurity, steam to eliminate fat, oil-water separation, crushing, sterilizing, enzymolysis, inactivating enzyme, concentration, drying and others. The present invention has the advantages of high protein content in the products, high bioavailability, no environmental pollution, low power consumption, etc. The products have the effects of promoting animal growth, regulating immunity, preventing and treating diseases, etc. and are used mainly in raising animal and as nitrogen source for biological culture.

Description

technical field [0001] The invention relates to biological products and bioengineering technology, in particular to a polypeptide and protein feed produced by applying bioengineering technology. Background technique [0002] In the past, people used the edible parts of low-value fish and shrimp and the processed waste of aquatic animals as raw materials for the production of fish meal. The traditional method of processing fish meal is to cook the raw materials, press to degrease, separate oil and water, recover fat, and turbid water Discharging, after degreasing, the degreased material is dried under normal pressure and high temperature, air-dried, and preservatives and antioxidants are added to make fish meal of 20-40 mesh. During its processing, protein loss is serious, bioactive components are destroyed, and resources are wasted. A large amount of sewage pollutes the environment during the production process. High energy consumption and high cost. The product contains ...
