| 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 quality of dried meat products and the drying kinetics significantly depends on the status of the raw material going into the drying process. The aim of this study was the determination of the impact of meat status (fresh, mature, frozen-thawed) on the drying kinetics and the resulting quality in terms of colour changes and spectrally deductible information. Drying tests were conducted using meat from organically raised bulls. In fresh meat, freezing leads to a decrease of the drying rate, whilst for matured meat the opposite is true. Aging and freezing have little effect on the end product quality in terms of final product colour. However, water content can be detected hyperspectrally and resolved spatially for all stages of the pro-cess. With... |

| Tomatoes (Solanum lycopersicum) are one of the most consumed vegetables worldwide. However, tomato allergies in patients suffering from birch pollen allergy occur frequently. Due to highly similar protein structures of the tomato allergen Sola l 4 and the major birch pollen allergen Bet v 1, patients cross-react with allergenic proteins from tomato as well as other fruits or vegetables. The aim of this study was to quantify Sola l 4 in various tomatoes differing in color, size and shape for identification of varieties with a reduced allergen level. Therefore, an indirect competitive ELISA using a specific polyclonal Sola l 4 antibody was developed. In addition, two varieties, both cultivated either conventionally or organically and furthermore... |

| Consumer trust in the food industry is heavily reliant upon accurate labelling of meat products. As such, methods which can verify whether meat is correctly labelled are of great value to producers, retailers, and consumers. This paper illustrates two approaches to classify between, fresh and frozen thawed, and in a novel manner matured and matured frozen-thawed, as well as fresh and matured beef using the 500-1010 nm waveband, captured using hyperspectral imaging, and CIELAB measurements. The results show successful classification based upon CIELAB between 1) fresh and frozen-thawed (CCR = 0.93), and 2) fresh and matured (CCR = 0.92). With successful classification between matured and matured frozen-thawed beef using the entire spectral range (CCR =... |

| Direct heat treatment of two milk types, skimmed and non-standardised, was performed by instant steam infusion and compared with indirect heating. Infusion conditions were temperatures of 72-120°C combined with holding times of 100-700 ms, and indirect heat conditions were 72°C/15s and 85°C/30 s. The activity of indigenous enzymes; alkaline phosphatase, lactoperoxidase, xanthine oxidase and -glutamyl transpeptidase was evaluated. Mainly the infusion temperature was determinant for inactivation. Whey protein denaturation represented by -lactoglobulin increased significantly with infusion temperature. The non-standardised milk had a higher denaturation rate than skimmed milk. The effect of instant infusion on pH and milk fat globule size in relation to... |

| The effect ofdipping and vacuum impregnation (VI) pretreatments with lemon juice solution on the quality and stability of organic and conventional frozen apples was investigated. Fresh apples were characterized; organic apples showed, at equal starch and ripeness index, a lower sugar content, and higher acidity than conventional ones. The polyphenol content was slightly higher in organic apples than in conventional ones while polyphenoloxidase activity was similar. No differences in color and firmness were evidenced. Dipping affected organic and conventional apples’ color by determining an increase of lightness (!L∗ ! 4) and h° (!h° ! 6) parameters. VI reduced the lightness of apples (!L∗ ! −3) but the addition of lemon juice counterbalanced the lightness... |

| Ziel des Projektes ist die Entwicklung ökologischer Zutaten aus der Yamswurzel Dioscorea batatas. Durch die Verwendung der D. batatas können Mehlmischungen in ihren sensorischen, physiologischen und gesundheitlichen Eigenschaften aufgewertet werden. In der Bio Branche gibt es eine Vielzahl an Mehlmischungen für Back- und Teigwaren aus Mais, Kartoffel, Reis, Soja und Buchweizen, hier werden oft Zusätze wie Johannisbrotkern- und Guarkernmehl verwendet. Die D. batatas wird bereits in Deutschland nach den Richtlinien des ökologischen Landbaus im Freiland angebaut. Um das neu entwickelte Produkt sowohl im handwerklichen als auch industriellen Bereich einführen zu können, wurde der Einfluss der Verarbeitungsschritte auf die Qualitätsparameter untersucht. Zur... |

| Die Eignung aus Japan stammender Möhren (Daucus carota L. var. Nutri Red) für ökologischen Anbau und Bio-Saftherstellung nach gewerblichen/industriellen Standardverfahren wurde im Rahmen des Projektes geprüft. Diese Möhren enthalten das gesundheitsfördernde Carotinoid Lycopin, das sonst fast ausschließlich in Tomaten vorkommt. Die Carotinoidgehalte der frischen Möhren (Lycopin, Beta-Carotin, Phytoen, Phytofluen) bleiben während der Saftherstellung nach einem Standardverfahren weitgehend erhalten; cis-Isomere des Lycopins entstehen nicht. Wasserlösliche Inhaltsstoffe mit einem hohen antioxidativen Potential und damit möglicherweise gesundheitsfördernder Wirkung reichern sich im Saft an. Aus ökologisch erzeugten Nutri Red-Möhren kann damit ein... |

| In recent years, the organic sector has put significant efforts in the development of clear definitions for gentle and quality oriented processing of plant based foodstuffs to supplement existing regulations. Concrete quality standards for different types of processing are under development in several CoreOrganic Plus projects. However, there is still a significant need for development of a Code of Practice. Quality of a product and sustainability of production depend on the cumulative impacts of each processing step in the food chain, as well as the quality of the raw material. With increasing demands by the consumers who expect high quality foods produced sustainably and preferably regionally (SusOrganic consumer survey), pressure on the producers is... |
