I use to run a method to analyse all the aminoacids in a food sample. For that I have to hydrololyse the sample and in the last stage of the method I read the amino acids with a ion exchange chromaotgraphy. However, when using this method, due to the hydrolysis, the glutamine transforms into glutamic acid, thus in my result I get a big peak fot glutamic acid and I cannot read glutamine.
My question is if there's a method to quantify glutamine in a food sample.
