Product feature
Lysine is one of the essential amino acids of human beings and mammals,which cannot be synthesized by the body itself and must be supplemented from food. Lysine has positive nutritional significance in promoting human growth and development, enhancing body immunity, antiviral, promoting fat oxidation, relieving anxiety and other aspects, but also can promote the absorption of some nutrients, can work synergistically with some nutrients,and better play the physiological functions of various nutrients.
Application fields
It is used in pharmaceutical industr y. Lysine can be used to prepare complex amino acid infusion, which is better than hydrolyzed protein infusion and has fewer side effects. Lysine can be mixed with various vitamins, made into nutritional supplements, easy to be absorbed by gastrointestinal af ter oral. Lysine can also imp rove the pe rfo rmance of some d rugs, improve the efficacy of drugs.
Used in food industr y. Lysine is one of the important components of protein. It is one of the eight amino acids which can not be synthesized by human body itself but is very needed. It is an excellent food fortifying agent.
Advantage
Step 1: Fermentation
At present, the commonly used lysine production strains mainly include Escherichia coli, mutant streptococcus, clostridium and so on. Fermentation conditions include temperature, pH, oxygen supply, etc., which need to be adjusted differently for different strains and processes.
Step 2: Purification
The purification of lysine is a key step in the production process, which directly affects the quality and cost of the product. At present, the common purification methods include ion exchange, gel filtration, dialysis and so on.
Third, the advantages and application prospects of lysine production process
Step 1: Advantages
The advantages of the lysine production process are mainly reflected in the following aspects:
High efficiency: the use of the latest technology can improve production efficiency and reduce costs.
Environmental protection: the production process will not produce pollutants, in line with environmental requirements.
Quality stability: The use of advanced production technology can ensure the quality and stability of products.
