Metabolite profiling on wheat grain to enable a distinction of samples from organic and conventional farming systems

Abstract

Based on individual cultivars, metabolite profiling showed promising results for the categorization of organic and conventional wheat. Further investigations are necessary with wheat from more growing seasons and locations before definite conclusions can be drawn concerning the feasibility to evolve a combined set of biomarkers for organically grown wheat using metabolite profiles.

Using metabolomics to describe food in detail

“…In a more recent study, Bonte et al (2014) used GC-MS profiling to compare 11 wheat cultivars grown in controlled conventional and organic conditions, and they found significant differences in the concentration of specific metabolites in winter Using metabolomics to describe food in detail 209 cultivars. Only a few metabolites were identified.…”

Research on organic food quality needs a system approach

“…One of the methods, metabolite profiling, is successfully applied for organic food authentication. This is demonstrated in the paper from Bonte et al for wheat samples derived from different farming systems …”

“…This is demonstrated in the paper from Bonte et al for wheat samples derived from different farming systems. 4 Organic food quality research, as a new research field, gets its first critical analysis of the status-quo in relation to concepts, definitions and methodological approaches. Zał ȩcka et al identify gaps and future research challenges, 5 while two research articles deal with the influence of farming (Bodroza-Solarov et al) 6 and processing (Kazimierczak et al) 7 on the quality of organic food products.…”

Foodomics: A new tool to differentiate between organic and conventional foods

“…Using orthogonal projections to latent structures discriminant analysis (OPLS-DA), differences in the chemical composition at the metabolome level of the two types of white cabbage were observed. Another untargeted study, based on GC-MS metabolite profiling followed by a PCA, analyzed 11 wheat cultivars grown under highly controlled conditions in a conventional versus organic farming system, and they reported significant differences in concentrations of both identified and nonidentified metabolites in different winter wheat (Triticum aestivum L.) cultivars [21]. The occurrence of myoinositol was higher in organic wheat grains.…”
