Determination of the Physiological Amino Acid Status for Identification of the Culture System of Wheat and Carrots - Method and Validation

摘要

Wheat and carrots produced by organic or conventional farming have been investigated by chemical analysis to estimate potential effects on their physiological amino acid status. The samples came from scientific field trials. The methods used are basedon precise chemical analysis of substances of the N-metabolism of the plant. The approach for the differentiation and identification of samples of carrots and wheat and its validation are described. It is shown, that the significant differentiation andthe correct identification of coded samples of different production conditions were possible. This was achieved by optimizing the precision and accuracy of measurement and by a view of the plant organism, which is oriented on the N-metabolism and its functions.
