Amino acids are the basic substances that constitute proteins required for animal nutrition, and have two functional groups: amino and carboxyl. Essential and non-essential amino acids in the human body are mainly derived from the digestion and absorption of food, so it is very important to determine the content of amino acids in the food. Amino acids that meet the standard conditions can be used as certified reference materials for the development of chromatographic test methods, instrument correction, qualitative and quantitative analysis.
In the industrial field, chromatographic technique is mainly used for qualitative and quantitative analysis of amino acids in products. In addition to the application in the food industry, amino acids are also widely used in the pharmaceutical, additive and cosmetic industries. Many industries involve the use of amino acid certified reference materials for chromatographic analysis.
Food industry: In the food industry, amino acids are usually used as seasonings. For example, the sweet dipeptide synthesized by aspartic acid and phenylalanine, glycine and lysine are mostly used in soft drinks, coffee, dairy products, etc. In addition, glycine can be used as an antibacterial agent, food spice and others. The content of additives in food is an important indicator to determine whether the food meets the standard, which requires the use of standard amino acids with high purity as a reference for chromatographic analysis.
Pharmaceutical industry: In the pharmaceutical industry, amino acid products can be used as nutrients and metabolic modifiers, with anti-ulcer, anti-radiation, antibacterial, cancer, hypnotic, and painful effects. At present, the use of peptide drugs is also increasing. In the pharmaceutical industry, the amount of amino acids used is huge, and the determination of the degradation products of drugs in the metabolic process requires the use of standard amino acids for qualitative analysis.
Feed additives: The main effect of adding amino acids in animal feed is to promote animal growth and development, improve meat quality, increase livestock and poultry production capacity, increase milk and egg production, save protein feed, and reduce costs. The commonly used amino acids in the feed additive industry are mainly methionine and lysine. Methionine could promote the synthesis of choline and epinephrine lipotropic. Lysine can enhance the origin of livestock and poultry, improve disease resistance, and promote the healing of trauma. The use of standard methionine and lysine is usually for chromatographic quantitative analysis when researching feed formulations.
