Amino acids are the basis of protein and the smallest unit of protein after digestion and absorption. Scientists believe that there are 22 important amino acids, and the human body must have 9 amino acids, they are: leucine, valine, isoleucine, lysine, histidine, phenylalanine, tryptophan, threonine, methionine.
At present, the main production methods of amino acids are as follows:
① Fermentation method: direct fermentation method and added precursor fermentation method.
② Extraction method: protein hydrolysis, extracted from hydrolysate. Cystine, cysteine and tyrosine.
③ Enzymatic method: The use of enzymes produced by microbial cells (microorganisms) to produce amino acids.
④ Synthesis method: DL-methionine, alanine, glycine, phenylalanine.
In the production process of the above amino acids, the second one related to ammonium bicarbonate is the extraction method. The following is a brief introduction to this process.
The main raw materials of amino acid extraction are: animal hair, hydrochloric acid, ammonium bicarbonate and so on.
The main production process is:
Cleaning: the animal hair purchased in the market is initially washed with water.
Protein hydrolysis: The concentrated hydrochloric acid solution is mixed with the cleaned animal hair, so that the protein in the animal hair is hydrolyzed to: cystine, cysteine and tyrosine and other amino acids.
Amino acid fractional extraction: through the extraction agent to extract the amino acid fractional extraction.
Acid containing wastewater treatment: after extracting amino acids, the aqueous solution is acidic, and mixed with the ammonium bicarbonate solution dissolved in advance, the double decomposition reaction occurs, so that the acidity of the solution is reduced, and ammonium chloride is produced again.
In the process of amino acid production by extraction method, ammonium bicarbonate is mainly used to treat acidic wastewater, which can reduce acidity and purify water quality.
Desenlai Chemical currently has ammonium bicarbonate packaging specifications of 50kg/1000kg, customers can flexibly choose according to demand. In addition, Desenlai Chemical base Dezhou new planning part of the ammonium bicarbonate capacity, is expected to put into operation in the second half of this year, Dezhou base put into operation, Desenlai chemical ammonium bicarbonate will form a north-south echo supply pattern, welcome customers consultation and cooperation.
