Embodiment 1
[0031] Take 100 kg of artificially cultured kelp, wash it with water to remove impurities and foreign matter. Use a shredder to cut the dry-controlled kelp with no moisture on the surface into small pieces of 2-3cm, add 500 kg of 75% ethanol solution, stir and extract at room temperature for 24 hours, then filter with suction, and the filtrate is concentrated and evaporated under reduced pressure Concentrate to dryness, add 10 kg of 0.02mol / L HCl to dissolve and set aside. Add 100 kg of 6 mol / L HCl to the filter residue, extract on a boiling water bath for 24 hours, and filter with suction. The filtrate is concentrated to dryness with a vacuum concentration evaporator, and 10 kg of 0.02 mol / L HCl is added to dissolve it and combine with the above solution. The obtained 20 kilograms of amino acid extracts are first loaded onto column PVPP (10 × 35 cm, polyvinyl polypyrrolidone) and eluted with 10 kg of distilled water, and the pH is adjusted to be 2; continue to go up to 732 ca...
Embodiment 2
[0033] Take 80 kg of artificially cultured kelp, wash it with water to remove impurities and foreign matter. Put the clean kelp in a hanging cage of 1m in length×width×height to control the water for 1 hour, cut the dried kelp into small pieces of 3-5cm with a shredder, put it into a tissue masher and homogenize it for 2- 3min. Collect the kelp homogeneous solution, add 350 kg of 75% ethanol solution in a stainless steel stirring pot, stir and extract continuously at room temperature for 20 hours, then filter with suction, concentrate the filtrate to dryness with a vacuum concentration evaporator, add 0.02mol / L HCL 5 kg was dissolved for later use (solution 1, free amino acid extract). Add 50 kg of 6mol / L HCL to the filter residue, extract on a boiling water bath for 20 hours, filter with suction, concentrate the filtrate to dryness with a vacuum concentration evaporator, add 5 kg of 0.02mol / L HCL to dissolve (combined with the amino acid extract) and mix with the above solut...
Embodiment 3
[0035]Take 50 kg of artificially cultured kelp, wash it with water to remove impurities and foreign matter. Put the clean kelp in a hanging cage of 1m in length x width x height to control the water for 1 hour, cut the dry kelp into 3-5cm small pieces with a shredder, put it into a tissue grinder and homogenize for 1- 2min. Collect the kelp homogeneous solution, add 200 kg of 75% ethanol solution in a stainless steel stirring pot, stir and extract continuously at room temperature for 18 hours, then filter with suction, concentrate the filtrate to dryness with a vacuum concentration evaporator, add 0.02mol / L HCL 3 kg was dissolved for later use (solution 1, free amino acid extract). Add 40 kg of 6mol / L HCL to the filter residue, extract on a boiling water bath for 18 hours, and filter with suction. One merged. The 6 kilograms of amino acid extracts obtained are first loaded onto column PVPP (10 × 35 cm, polyvinyl polypyrrolidone) after elution with 3 kg of distilled water, a...
