The techniques involved in successfully separating and quantifying the amino acids vary from instrument to instrument. However, the processes for amino acid analysis are similar, involving hydrolysis, labeling, separation, and detection followed by data analysis.
The techniques involved in successfully separating and quantifying the amino acids vary from instrument to instrument. However, the processes for amino acid analysis are similar, involving hydrolysis, labeling, separation, and detection followed by data analysis.In the traditional method for breaking down proteins for amino acid analysis, the protein or peptide sample is first hydrolyzed in a vacuum or inert atmosphere. A gradient of buffers elutes the sample, which then passes through a resin-packed ion-exchange column. The ninhydrin reagent is applied turning the primary amino acids a bluish color and the secondary amino acids brownish-yellow.
2006 Amino Acid Analyzers Market Demand by Product Type
The ramifications of this automated technique, which was first pioneered by Nobel laureates Stanford Moore and William Stein in 1958, have influenced research in areas such as nutritional analysis of animal feed, quality control of pharmaceuticals, and detection of amino acid deficiency disorders.
Amino acid analyzers are used for maintaining high manufacturing standards in the food industry. By testing specific amino acid profiles in fruit juice, for instance, scientists are able to determine not only the origin of the fruit and the conditions in which it was processed, but also the climate in which the fruit grew and how ripe it was when squeezed.In dairy products, analyzers can detect the presence of unwelcome protein compounds, and, as a result, verify the purity and freshness of a batch of milk. A thorough amino acid analysis can also guarantee the safety of products that are particularly susceptible to contamination and for products that consumers demand the highest degree of reliability, such as baby formula.Growth for the AAA market is expected to be moderate and reach nearly $100 million by 2011. This growth is fueled by replacements of legacy systems and continued growth from the food and beverage industry. However, alternative methods like capillary electrophoresis and mass spectrometry techniques are also impacting its growth.
