Discrimination of conventional and organic white cabbage from a long-term field trial study using untargeted LC-MS-based metabolomics Organic Eprints
Mie, Axel; Laursen, Kristian Holst; Aberg, K. Magnus; Forshed, Jenny; Lindahl, Anna; Thorup-Kristensen, Kristian; Olsson, Marie; Knuthsen, Pia; Larsen, Erik Huusfeldt; Husted, Søren.
The influence of organic and conventional farming practices on the content of single nutrients in plants is disputed in the scientific literature. Here, large-scale untargeted LC-MS-based metabolomics was used to compare the composition of white cabbage from organic and conventional agriculture, measuring 1,600 compounds. Cabbage was sampled in 2 years from one conventional and two organic farming systems in a rigidly controlled long-term field trial in Denmark. Using Orthogonal Projection to Latent Structures-Discriminant Analysis (OPLS-DA), we found that the production system leaves a significant (p = 0.013) imprint in the white cabbage metabolome that is retained between production years. We externally validated this finding by predicting the production...

The OrgTrace project: Content, Bioavailability and Health Effects of Trace Elements and Bioactive Components of Food Products Cultivated in Organic and Conventional Agricultural Systems Organic Eprints
Husted, Søren; Laursen, Kristian Holst; Larsen, Erik Huusfeldt; Kapolna, Emese; Knuthsen, Pia; Søltoft, Malene; Bügel, Susanne; Mark, Alicja Budek; Lauridsen, Charlotte; Jacobsen, Maja; Jørgensen, Henry; Halekoh, Ulrich; Kristensen, Kristian.
Trace elements, bioactive secondary metabolites and vitamins are among the most important quality parameters in plants. Yet, very little information is available on their content, bioavailability and health effects in organically grown plant food products. The main objective of OrgTrace is to study the impact of different agricultural management practices relevant for organic farming on the ability of cereal and vegetable crops to absorb trace elements from the soil and to synthesize bioactive compounds (secondary metabolites, antioxidant vitamins and phytates) with health promoting effects. Based on different plant products produced in OrgTrace, diets were composed and the bioavailabilities of health promoting substances were analyzed in a human...
