Amino acids are the basic units that make up proteins, and they are organic molecules with amino groups (-NH2) and carboxyl groups (-COOH). In living organisms, 20 different amino acids are linked together in a specific order to form proteins, each with a unique three-dimensional structure, which in turn performs various physiological functions, such as catalyzing reactions, transmitting signals, providing structural support, etc.
The development of industrial economy has profoundly improved people's living conditions, while the material life is becoming more and more affluent, people's attention to dietary health is also increasing day by day, and the share of food with nutritional function in the consumer market is gradually expanding. There are at least eight amino acids that are essential for maintaining the physiological activities of the human body, and they are also being taken seriously with the attention of people to health problems. Some essential amino acid components, such as lysine, glutamic acid, aspartic acid, etc., are increasingly valuable in the food industry.
The amino acids are produced by microbial fermentation broth method, which has the advantages of stable quality, high purity and high efficiency. The use of nanofiltration membranes for the treatment of amino acid fermentation broths has many advantages:
1.The dependence of nanofiltration membrane on pretreatment is low, which can effectively save the investment.
2.The small pore size of the nanofiltration membrane can not only remove solid impurities and hyphae, but also remove proteins and inorganic salts, and the resulting bacterial residue can be used as feed, reducing waste liquid pollution and protein pollution of resin;
3.The membrane module has strong anti-pollution ability, can effectively prevent impurities from clogging while ensuring filtration efficiency, is easy to clean and maintain, and has a long service life;
4.It does not rely on high temperature and chemical reaction, and there is no phase change in treatment, which can fully guarantee the molecular activity of amino acids, avoid high-temperature decomposition, and save the consumption of heat energy;
5.It occupies a small area and has strong automation, which can save labor costs.
The application of nanofiltration membranes to produce amino acids has stability and technical reliability, which can bring many benefits to improve production quality and economic benefits.
