| Environmental conditions, e.g. pH and the presence of Fe2+ are well known factors that influence the product profile of the myrosinase catalysed hydrolysis of glucosinolates. Depending on the plant genera, the species and tissue of origin myrosinase isoenzymes (thioglucohydrolase EC 3.2.1.147) have different characteristics in terms of MW, subunit composition and pI. However, the influence of these parameters on the outcome of glucosinolate hydrolysis has not been traditionally studied, which hinders the full exploitation of the catalytic potential of these enzymes. In the present experiments the effect of myrosinase type on the products obtained in the hydrolysis of glucosibarin was studied by MECC using two B. carinata myrosinase preparations differing... |

| An Hand verschiedener Beispiele aus dem Bereich der Gentechnologie konnte gezeigt werden, dass molekularbiologische Methoden mit ökologischen Prinzipien nicht vereinbar sind. Der produktbezogene Qualitätsnachweis, der vor allem auf Inhaltsstoffzusammensetzungen, invitro Tests und Akuttoxizitätstests beruht, erscheint nicht ausreichend, um die Qualität von GVNahrungsmittel umfassend zu definieren bzw. eine bessere Qualität dieser Produkte nachzuweisen. Außerdem erscheint die derzeit angewandte Risikokontrolle mangelhaft und revidierungsbedürftig, da die Prozessqualität, die alle Produktionsschritte umfasst, überhaupt nicht in Betracht gezogen wird. Die „Mathematisierung der Natur“ (HUSSERL 1962) bereitete die Grundlage für die technische Naturbeherrschung,... |

| The processor survey shows the general principles and understanding of quality for the processing of organic food from the processors’ point of view. In addition, possible problem areas regarding the question of product quality such as raw material, processing techniques, storage etc. are worked out. The results of the survey support the identification and definition of critical and essential control points as well as product quality parameters. This survey can therefore conclude three points of actions to improve the process quality. - Handling of raw material: transportation, storage, pre-processing - Nutritional, safety and sensory QCCP - Cooking: time and temperature - Nutritional and sensory QCCP - Preserving/ sterilizations -... |

| CONCLUSIONS Organic production systems can make important contributions to food supply stability and farmer livelihoods by establishing soil fertility, providing diversity and, therefore, resilience to food production systems in light of the many uncertainties of climate change. In particular, they contribute positively to food stability in terms of fertile and well structured soils, improved water retention, protection of biodiversity with beneficial side-effects on phytomedical stability and nutrients, and water use efficiency. Agricultural production methods specifically adapted to microclimates, production of diverse products, and cropping methods emphasizing soil carbon retention are most likely to withstand climatic challenges and contribute to... |

| BACKGROUND: Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day−1 per hen of three coloured carrot varieties (orange, yellow and purple) as forage material in comparison with a standard feed control on egg production, egg yolk colour and deposition of carotenoids in the yolk. RESULTS: Carrot supplementation reduced feed intakes significantly, but not on a dry matter basis. Orange carrot treatment significantly reduced egg mass production, whereas yellow and purple carrot treatments did not differ from the control. Egg and yolk weights of all carrot-supplemented treatmentswere significantly lower than those of the... |

| During last decades the consumer trust in food quality has drastically decreased, mainly because of the growing ecological awareness and several food scandals. Consumers started to look for safer and better controlled foods, produced in more environmentally friendly system. Organically produced foods are widely believed to satisfy the above demands; up to now research studies have partly confirmed this opinion. Organic crops contain fewer nitrates and nitrites and fewer residues of pesticides than conventional ones. They contain as a rule more dry matter, vitamin C, phenolic compounds, valuable amino acids and total sugars; however the level of carotenoids is often higher in conventional plant products. Organic crops contain often more mineral... |

| 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... |

| Changes in phytic acid content, activity of phytase and α-amylase in rye breads were determined during rye bread making. The activity of phytase is highest in grain and flour whereas the activity in the sourdoughs is almost the half of the activity in the flour. The activity was unchanged in the dough after mixing and proofing. Degradation of phytic acid (IP6) into lower inositol-phosphates and free phosphate is almost completed during the production of rye bread with long fermentation time whereas the degradation is less completed when whole grains are included in the recipe. In rye bread made from milled rye (DB00), 99% of IP6 is degraded and IP3 becomes the dominating inositol-phosphate in this bread type presumably resulting in a high level of... |

| The objective of this study is to investigate the potential of different durum wheat varieties that could be adapted for organic farming. In this context, four experimental years studies (2001, 2002, 2003 and 2004) were carried out in order to assess fourteen durum wheat varieties including nine old and five improved varieties conducted under organic and conventional cultivation methods and in two cereal growing locations : Kef "Boulifa" : low semi-arid and Bousalem “El Kodia” : higher semi-arid. Studied parameters included (i) grain yield, (ii) yield stability using coefficient of variation, linear regression coefficient, deviations from regression, ecovalence of Wricke, ecovalence of Shukla, ecovalence of Plaisted and Peterson and superiority index of... |

| On most continents food production has surpassed the growth in population (Knudsen et al. 2006). Still it is estimated that approximately 1 billion people are undernourished (FAO 2011) and the greatest number of people suffering from chronic hunger are living in South and East Asia (FAO 2012a). More than half (3.1 billion people) of the developing world’s population live in rural areas. Of these, approximately 2.5 billion derive their livelihoods from agriculture (FAO 2012a). The majority of small scale farmers in the global south lack financial and natural resources to be able to improve production and food security (Knudsen et al. 2006). A United Nations’ report on organic agriculture and food security concludes that organic agriculture increases the... |

| Abstract – The effect of different fertiliser types (cal-cium ammonium nitrate, fresh farmyard manure, composted farmyard manure and nettle extract) on the hygienic quality of fresh and washed lettuce was tested in two trials in summer 2004 and 2005. The hygienic quality was described by total aerobic bacte-rial count and level of coliform bacteria, Escherichia coli, Salmonella Enteritidis, Enterobacteriaceae. No Salmonella Enteritidis was detected in any sample. E. coli was isolated independent of the fertiliser type in low concentrations. The total aerobic bacterial count, the levels of Enterobacteriaceae and coliform bacteria tended to be lower after application of mineral fertil-iser but on a very low level. The washing process had no significant... |
