| Die Nachfrage der Konsumenten nach gesunden, sicheren Lebensmittel hoher Qualität steigt. Der ökologische Landbau umfasst die gesamte Prozesskette vom Feld zur Gabel; während aber die EU-Richtlinie (EU 2091/92) den Anbau detailliert beschreibt, fehlen Angaben zur Verarbeitung von Lebensmitteln. Daher müssen Prozessschritte auf ihre Auswirkung auf Lebensmittelsicherheit und vor allem –qualität untersucht werden. Dazu eignet sich eine Analyse kritischer Kontrollpunkte (QACCP). Das Projekt Core-Organic QACCP bringt diese Fragen zusammen. An einem ausgewählten Produkt wird die gesamte Prozesskette vom Feld zur Gabel untersucht. Das Ziel ist es, sowohl den Anbau als auch die Verarbeitung zu überprüfen und die Produkte auf Sicherheit, Qualität und Gesundheit zu... |

| The content of secondary plant compounds in plants is influenced by various environmental factors. Cultivation and fertilization are factors which are characteristic for the farming system organic or conventional. Within a german governmental funded project (BÖL02OE170/F) carrot, maize and wheat samples from different farming systems (defined trials and farm pairs) are differentiated and classified using their polyphenolic and carotenoid contents and profiles, respectively. The samples from organic farming could be differentiated from samples which were conventionally grown as statistical significant for carrot and wheat samples in a two year repetition. The samples could be classified by both, polyphenolic as well as carotenoid profiles. The sum... |

| 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... |

| Background: According to the European regulation N°834/2007, processing of organic food should preserve the essential qualities of the fresh raw material. Thus, assessment of processed food quality should include verification of the absence of additives and contaminants and preservation of the sensorial, nutritional and health values of the raw material. In this paper, a quantifiable concept of naturalness measuring global quality loss due to processing and storage of raw organic material is proposed. This indicator is based on Front face fluorescence; a global and sensitive technique able to assess in real time and non-destructively these various dimensions of the food quality. Results: A strong relationship between the naturalness levels estimated... |

| Microencapsulation is a technique by which sensitive ingredients are entrapted in thin polymeric matrix or coats. Microcapsule contents or „core“ materials are generally protected from adverse environmental conditions. Microencapsulation in the food industry can be used by every class of food ingredient. The microencapsulation of probiotics, the live microbial food supplements, is developing since the past decade. However many promised positive effects of probiotics are not yet proved scientifically. Furthermore research on the effects of the probiotic bacteria and the microencapsulation techniques is needed. This work aimed at just observing the adverse effects of the microencapsulation techniques (e.g. by probiotics). Due to this, there is a... |

| 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. |

| Nanotechnology, the science of the ultra small, is up-and-coming as the technological platform for the next wave of development and transformation of agri-food systems. It is quickly moving from the laboratory onto supermarket shelves and our kitchen tables (Scrinis and Lyons, 2007). Therefore we investigated in a literature review and a comparison of the findings with the EU regulation of organic farming to what degree nanotechnology can be applied in organic food production. The regulations do not restrict the use of nanotechnology in general. Because little is known about the impact on environment and human health, precaution should be taken when it comes to applying this technology in organic food production. |

| 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... |

| Quality traits are highly focused upon in the marketing of organic food products. There is a need to define and measure quality as consumers seem to have preconceived notions about the superior health value and taste of organic compared to non-organic products. A commonly held opinion among many consumer groups is that organic farming guarantees optimum quality, despite the fact that this remains unproven. The aim of this paper is to contribute to a better understanding of the complexity of quality traits in a plant-based food product, using carrots as an example. Selected designated quality aspects are presented to describe the complexity of quality and discuss the challenges of using these aspects in differentiating between organic and conventional... |

| Background: In the frame of the QACCP (Quality Assessment of Critical Control Points)project of the Core Organic platform, the potential of front face fluorescence for assessment of carrot quality and critical points in processing was demonstrated. The impact of processing on quality loss of organic baby food puree manufacturing was analyzed, including the different steps of the process. The impact of the raw material preprocessing was also studied. Attention was especially paid on potential neoformed contaminants produced during heat treatments. Material and Methods: Two assays were analyzed among others: one at industrial level to study the different steps of the process; the other at pilot plant to compare different raw material preprocessing.... |

| 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... |
