A possibility of determining the authenticity of organic wheat using GC-MS
Krulj, Jelena A. ...
Qualitative analysis of liposoluble wheat extract from conventional, integrated, organic, biodynamic and control farming systems was performed by gas chromatography with mass spectrometry (GC-MS). ...Organic and biodynamic farming systems were cliose to each other versus conventional and integrated which are similar in fertilization and plant protection. In the control treatment no fertilization or plant protection was used. Cluster analysis (CA) was aaplied to classify the samples according to lipid profiles in wheat from different farming systems. The obtained results showed the better discrimination of wheat samples was achieved by analyzing the peak area after 18 min retention time (non-saponifiable lipid fraction), than used the peak area for the whole chromatogram. The study has found that this method can be a potentially used for making a distinction between organic and non-organic wheat production.
