title: Effect of different production systems on chemical profiles of dwarf French bean (Phaseolus vulgaris L. cv. Top Crop) pods.
abstract: The chemical composition of dwarf French bean (Phaseolus vulgaris L.) cv. Top Crop was compared among five production systems: conventional, integrated, organic, and biodynamic production systems and the control. Determination of sugars and organic acids was performed with a HPLC system, and identification of individual phenolic compounds using HPLC-MS. The chemical composition of the beans was unaffected by the production systems; however, the content levels of individual compounds were changed. The pods from integrated production contained the lowest levels of glucose and sucrose and the highest levels of catechin, procyanidin dimers, and a vanillic acid derivative. The control treatment, as well as organic and biodynamic productions, positively affected the levels of sugar content and caused a lower content of catechin and trans-p-coumaroylaldaric acids. Beans from the conventional production system contained the lowest levels of fructose, glucose, ascorbic acid, and many phenolics from various groups.
