| A broad screening programme, covering the most general phytochemical groups of compounds, was developed on the basis of Thin Layer Chromatography (TLC). A total of 46 TLC systems, comprising 26 derivatization reagents, 3 stationary phases, and 4 mobile phases, were included. The TLC systems were classified according to the groups of phytochemical compounds detected: Alcohols and phenolic compounds; Carbohydrates; N-containing compounds; Organic acids and lipids; P-containing compounds; S-containing compounds, and Terpenoids. Furthermore, one group of TLC systems detected compounds from several of the mentioned groups. The screening programme was applied in the screening of potatoes (S. tuberosum L.), peas (P. sativum L.), kale (B. oleracea L.), carrots... |

| On the way to a new systemic research approach for organic food quality and health More than 50 researchers and supporters of the organic food sector met at the 1st scientific FQH conference from November 28th to 29th at the FQH research member institution FIBL in Frick (Switzerland). The two days were filled with presentations of latest research results of well-named scientists from across Europe covering topics from farm to table such as quality parameters of organic food, human health, the definition of quality and consumer expectations and legal legislation for organic food. The conference was embedded in two scientific discussions about the scientific future of organic quality research chaired by Hardy Vogtmann (president of the German Federal... |

| Auf der ersten wissenschaftlichen Konferenz über „Organic Food Quality and Health Research“ im Mai 2011 in Prag resümierte eine Wissenschaftlerin über die Bioqualitätsforschung, es gäbe tausende von Untersuchung über wertgebende und wertmindernde Substanzen, nur wenige Dutzend über Biomarker (z. B. Tierversuche) und fast keine über Gesundheitswirkungen. Ein anderer Forscher stellte auf der Tagung fest, dass von den 140 Tagungsbeiträgen kaum einer verarbeitete Lebensmittel behandelte. Diese Aussagen sind sinngemäß auch auf die Forschung über die Qualität biologisch dynamischer Lebensmittel zu übertragen. Einige Besonderheiten der Forschung über biodynamischer Qualität kommen hinzu: - Es gibt nur wenige wissenschaftlich begutachtete... |

| Based on investigations with samples of a fertilization trial started in 1980, some parameters of storage ability are evaluated. Microbial infestation of the product during incubation seems to be the most reliable parameter. But the circumstances of infestation are as unknown as the optimal test conditions. There is no reliable correlation between results of degradation tests, storage tests under optimal conditions and chemical contents of the product. The quality concept of product vitality (product-oriented), i.e. a product full of vigour, based on results of degradation tests is discussed. Ultimately, food quality standards are based on human priorities (human-oriented). Therefore, not only product characteristics, but also social, psychological,... |

| In dem wachsenden Markt ökologischer Lebensmittel werden Methoden zur produktorientierten Qualitätserfassung gefordert. Dabei geht es u.a. um die Unterscheidung von Produkten aus unterschiedlichen Anbauverfahren. Die Ziele des Projektes waren daher: 1. ausgewählte ganzheitliche Methoden gemäß ISO 17025 zu validieren, d.h. Laborprozesse festzulegen, sowie Einflussgrößen und Verfahrensmerkmale zu bestimmen, 2. zu testen, ob diese Verfahren eine Differenzierung von definierten Proben statistisch abgesichert zeigen können. . Diese Ziele konnten erreicht werden. Es wurde bestätigt, dass einige der Methoden auf Grundlage dokumentierter Prozeduren Lebensmittel aus definierten Anbauversuchen (u.a. aus dem DOK-Versuch am FIBL/CH) reproduzierbar unterscheiden... |
