https://www.chinesestandard.net, 26 Oca 2018 - 12 sayfa
This Standard specifies using the amino acid analyzer (ninhydrin post-column derivatization ion exchange chromatography) to determine the amino acid in foods. This Standard is applicable to determine the amino acid hydrolyzed by acid in foods, there are totally 16 kinds of amino acids such as aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, histidine, lysine, and arginine.
