| Organic food-processing standards generally prohibit the use of synthetic chemicals, many preservatives and other food additives that are widely used in the processing of conventional foods. However, there are frequent discussions about the underlying rationales, principles and criteria used to allow some processing methods and additives but other ones not. Consumers of low-input and organic food have specific expectations regarding quality characteristics of processed food. Organic processed products should therefore be sustainable and fulfil consumers’ expectations as much as possible. Our study reviewed current approaches and concepts in organic food processing, based on the results of a literature survey and a two-step Delphi expert survey focusing on... |

| The expert group for technical advice on organic production (EGTOP; thereafter called „the Group‟) in replying to point a) of the mandate concerning substances assessment concludes on the basis of the knowledge available in the group and information provided with the dossiers and by the Commission that: E 535 Sodium ferrocyanide anti-caking material, should be approved for use as a feed additive in salt for organic animal feed, subject to: - a maximum dose rate of 20 mg/kg NaCl (the maximum defined for human food) and - a limited time period, in order to provide a legal basis for current practice in the short term and to encourage the adoption of preferred carbonate alternatives longer term. E 566 Natrolite-Phonolite anti-caking material should be... |

| 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... |

| 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 -... |

| The aim of this review is to provide an update on factors contributing to quality of carrots, with special focus on the role of pre- and postharvest factors and processing. The genetic factor shows the highest impact on quality variables in carrots, causing a 7–11-fold difference between varieties in content of terpenes, β-carotene, magnesium, iron and phenolics as well as a 1–4-fold difference in falcarindiol, bitter taste and sweet taste. Climate-related factors may cause a difference of up to 20-fold for terpenes, 82% for total sugars and 30–40% for β-carotene, sweet taste and bitter taste. Organic farming in comparison with conventional farming has shown 70% higher levels for magnesium and 10% for iron. Low nitrogen fertilisation level may cause up to... |

| QLIF researchers have quantified effects on food quality and health of products such as wheat, forage, apples, milk and meat. The workshop identifies factors which cause variation of the product quality for different commodities. Experimental findings on quality of organic and low input foods will be compared with consumer expectations and attitudes. For selected quality improving measures their economic impact will be analysed. Furthermore, the role of processing in maintaining or improving specific ‘organic’ qualities will be examined. |

| A consumer as well as a processor survey has been carried out in order to identify awareness, expectations and demands on the quality of organic processed vegetable baby food. In this paper we present the preliminary results for German and Italian consumers when purchasing vegetable baby purees. In contrast to vegetable baby puree in general, organic vegetable baby puree is considered additionally under aspects of its processing, safety, health benefits and sustainability. Ideas about the processing of baby purees turn out to be rather fuzzy. The processor survey showed no differences between organic and conventional processing. Nevertheless there are possibilities to optimise the process quality and differentiate the organic processing from ordinary... |

| The overall objective of the subproject on processing, where the Delphi expert survey was an important task, is “to develop of a framework for the design of “minimum” and “low input” processing strategies, which guarantee food quality and safety.” It should support the overall aim of the integrated QLIF Project (Quality of Low-Input Food) in improving quality, ensuring safety and reducing costs along the European organic and “low input” food supply chains through research, dissemination and training activities. The method chosen was the Delphi method. The work was carried out in the form of a two step Delphi survey. In the first round 250 experts in 13 countries in Europe were involved, and were asked to respond to a standardised questionnaire in October... |

| Four concept papers outline parameters for the further development of organic food processing. They are based on other work already executed in the subproject 5 Processing in the QLIF-project, in particular the literature survey on “Underlying Principles in Organic and "Low-Input Food“ Processing – Literature Survey” published in 2004 by Schmid, Beck and Kretzschmar, as well as the “Approaches used in Organic/Low Input Food Processing - impact on food quality and safety” results of a Delphi survey from an expert consultation in 13 European countries.“ (Kretzschmar, Schmid, 2006). The four crucial topics highlighted in concept papers that have been chosen are summarised below: - 1rd Concept paper on the chances for a concept of “quality of origin” and on... |
