Different production methods also have a great influence on the effect of amino acids. The production methods of amino acids include chemical synthesis, enzymatic conversion, microbial fermentation, and hydrolysis. At present, the main methods of agriculture are hydrolysis and microbial fermentation. The acid hydrolysis method has low production cost and relatively simple production process. Most of the hydrochloric acid is hydrolyzed, and the amino acid content of the produced amino acid is high, but dechlorination treatment can also be carried out. The amino acid in the acid hydrolysis process is easily destroyed, especially the tryptophan of the auxin precursor is completely destroyed, but it is not so unpleasant, and the reasonable selection and application are also very good.
Enzymatic hydrolysis and microbial fermentation have relatively comprehensive amino acid species retention, high oligopeptide content and less harmful substances. These two production methods are undoubtedly the most suitable for use in agriculture, especially enzymatic hydrolysis. Some advanced technologies can be based on molecular weight. The orientation is sheared to obtain the desired molecular weight range, such as the molecular weight of the oligopeptide below 1000 Daltons. Although there are few fertilizer companies using enzymatic amino acids in China, it does not mean that the level of enzymatic amino acid technology in our country is not up to date, just because most domestic fertilizer companies have insufficient knowledge of amino acids and high raw material costs. Less in agriculture.
