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 fresh aquatic product processing waste and process according to the following processing steps: (1) remove impurity: fresh aquatic product processing waste is removed impurity. (2) Degreasing: degrease the fresh aquatic product processing leftovers 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 2.0:1, pulverize into a slurry of 80-300 mesh (0.18-0.05mm). (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 35-60°C. (6) Concentration and drying: Concentrate the sterilized slurry to a ...

Embodiment 3

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

Abstract

A process for preparing the polypeptide-protein feed from the low-value fish and shrimp and the leftover of aquatic products includes removing impurities, steaming for defatting, oil-water separating, pulverizing, sterilizing, enzymolyzing, deactivating enzyme, concentrating and drying. The obtained feed features high contents of polypeptide and protein, and high reward rate.

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 low-value fish, shrimp and aquatic product processing waste as raw materials for the production of fishmeal. The traditional method of processing fishmeal is to cook the raw materials, press to degrease, separate oil and water, recover fat, discharge turbid water, and degrease the material. After drying at normal pressure and high temperature, drying in the sun, adding preservatives and antioxidants, fish meal of 20-40 mesh is made. 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 low protein and is easy to oxidize and deteriora...
