| Consumer demand for healthy, safe and high quality food is increasing. Against this background, the demand for organically grown food has been growing rapidly. Organic farming contains the whole food chain from field to fork. An analyse system to optimise the process needs to be established (QualityAnalysisCriticalControlPoint). The aim of the transnational CORE-Organic QACCP project is a chain analysis which addresses the link between farm and fork and backwards from fork to farm. The objective is to improve product related quality management in farming and processing. The results presented here are dealing with food authenticity on farm level through biocrystallization measurements and food safety through pesticide residue and nitrate... |

| The biocrystallization method was standardised on carrot and wheat. With the standardised method samples from different farming systems could be successfully discriminated. For this paper, we investigated to what degree the standardised method can be adapted to other product classes like apples or Aloe vera. We found, that the sample preparation procedures must be developed for each new product whereas the conditions for the steps evaporation and crystallization as well as the evaluation of the patterns could be directly transferred. The variability as well as the factors of influence could be compared to those found on carrot and wheat samples. |

| Among consumers there is a growing demand for food products with a natural nutritional-physiological advantage over comparable conventional products. As part of an EU funded project, ALP is examining the possible impact of processing on nutritionally valuable milk components, using the example of conjugated linoleic acids (CLA). The extent to which processing influences the CLA content of the end product was determined by literature research and own investigations of organic and conventional butter. Furthermore, new chemical, sensory-based and bio crystallization methods were evaluated by ALP and the University of Kassel to determine the oxidation stability of butter. In a further step the storage stability of CLA enriched and conventional butter was... |

| With the Steigbild technique patterns are produced on thin-layer chromatographic paper and evaluated as a fingerprint of the sample as a whole. To be applied in routine analysis the method has to be standardised according to international standard norms. The operating procedures were documented and a method for the visual evaluation was standardised. Then several factors of influence were tested and the reproducibility was investigated. The method is able to differentiate patterns from samples from different farming treatments and processing steps. Farm pairs of organic and conventional farm management can be distinguished as statistical significant and classified according to the farming system for carrot and wheat samples. This represents a... |

| 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... |
