Embodiment Construction

[0034] The present invention is accomplished in the following manner:

[0035] 1. A method for producing deep-sea amino acids from fresh, non-polluting fish juice discharged from a fishmeal factory. First, the fish oil in the fish juice is separated and removed, and the aqueous solution after the fish oil is separated is concentrated, added acid, refluxed and hydrolyzed, cooled, and neutralized. To PH6.0-7.0, filter to obtain the filtrate, which is the deep-sea amino acid solution, which is characterized in that it is concentrated to a protein content of 10-15%, and food-grade hydrochloric acid containing 35% Hcl is added until the concentration of Hcl in the reaction system is 1.0-2.0mol , The reflux hydrolysis time is 3-5 hours.

[0036] 2. A method for producing deep-sea amino acids from fresh, pollution-free fish juice discharged from a fishmeal factory, concentrated to a protein concentration of 12.5%, hydrochloric acid concentration of 1.5mol, and reflux hydrolysis time ...

Abstract

The fish meal factory uses fresh small miscellaneous fish to produce fish meal through cooking, pressing, drying, crushing and other processes. The squeezed fish juice is directly discharged without treatment, seriously polluting coastal beaches and offshore waters. The invention utilizes the fresh fish juice discharged from the fishmeal factory, concentrates it, and hydrolyzes it with edible grade hydrochloric acid to eliminate the pollution of the fish juice discharged from the fishmeal factory to coastal tidal flats and near seas, and simultaneously produces nutritious deep-sea amino acids.

Description

technical field [0001] The invention relates to a method for preparing deep-sea amino acids from fresh fish juice discharged from a fishmeal factory. Background technique [0002] The existing commercially available polypeptides and amino acids are prepared from hydrolyzed soybeans, soybean meal, silkworm chrysalis, casein, blood fibrin and animal bones. Its disadvantages are high production cost and unbalanced or incomplete amino acid composition. The fish meal produced by the fish meal factory is to cook fresh, non-polluting small miscellaneous fish, and then squeeze, dry, crush and other processes to obtain the finished fish meal. The fish juice after pressing is discharged directly without treatment. The discharge of these nutrient-rich fish juices has caused serious pollution of water sources in my country's coastal areas, and is one of the main reasons for the frequent occurrence of red tides in the Bohai Sea, the Yellow Sea, the East China Sea and the South China Se...
