| 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... |

| Hops are a key ingredient for beer brewing due to their role in the creation of the foam characteristics, bitterness of the beers and aroma. Whilst in the past foam and bitterness were the key characteristics sought by the market, the last decade has seen a steep increase in demand of aroma hops for the production of crafts beers. Color of the final product plays a major role in quality perception of traders and brewers. Therefore, color changes were investigated to estimate the impact of bulk weight and thus drying time and conditions on the upper surface of the bulk. A calibrated imaging system consisting of a CCD camera and illumination was integrated into the dryer. Further, changes of and ß acid contents were investigated. Hops of the variety... |

| The Federal Organic Farming Scheme (FOFS): This scheme is a temporary funding source (2002 – 2007/2008) especially to support the whole organic farming sector (incl. research) in Germany. In the summer of 2001, the Federal Ministry of Consumer Protection, Food and Agriculture commissioned a project team comprised of representatives from associations and science and headed by the Federal Agricultural Research Centre to develop a proposal for a package of measures to foster organic farming in Germany. A hearing of representatives from trade and industry, associations, consultancy, science and administration laid the foundation for the team's work. Based on this work, the Federal Minister of Consumer Protection, Food and Agriculture Renate Künast decided to... |

| 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... |

| Instant infusion technology has been suggested as a gentle method for pasteurization of milk, and the overall aim of the research presented in the current PhD thesis was to investigate this suggestion. The effects of instant infusion pasteurization (IIP) was studied by characterization of the microbial inactivation and selected physical-chemical and functional properties of milk subjected to IIP at different temperatures in the range from 72°C to 120°C and holding times < 1s. Standard high temperature short time (HTST) pasteurization at 72°C for 15 s was used as reference treatment. It was found that IIP provided high inactivation of microorganisms, even at 72°C the total aerobic counts were almost equal to those of milk subjected to HTST... |

| BACKGROUND The potential of hyperspectral imaging (500–1010 nm) was evaluated for monitoring of the quality of potato slices (var. Anuschka) of 5, 7 and 9 mm thickness subjected to air drying at 50 °C. The study investigated three different feature selection methods for the prediction of dry basis moisture content and colour of potato slices using partial least squares regression (PLS). RESULTS The feature selection strategies tested include interval PLS regression (iPLS), and differences and ratios between raw reflectance values for each possible pair of wavelengths (R[λ1]–R[λ2] and R[λ1]:R[λ2], respectively). Moreover, the combination of spectral and spatial domains was tested. Excellent results were obtained using the iPLS algorithm. However,... |

| The present report is a part of the ERA-NET project SusOrganic: Development of quality standards and optimised processing methods for organic produce. The superchilling concept and the state-of-art of the technology are summarized with focus on potential implementation for small scale organic production. Production of processed organic food is mostly carried out by small and medium enterprises in demanding, competitive market conditions due to competition from highly cost-efficient large scale producers of conventional products and producers of locally grown food without certification requirements. The superchilling concept can be applied for organic meat and fish products, hereby helping the producer to supply the market with high-quality organic... |

| Thermal properties of selected organic products were investigated using novel DSC technique and methods of determination. The report includes determination of freezing temperatures, glass transition temperatures, amount of ice, and end of freezing point, heat capacity and thermal conductivity for selected cases. One part of the experimental work was devoted to investigate the difference between oils extracted from organic and conventional salmon. The main aim of the investigation was to understand if the organic food requires any special treatment during processing, when compared with industrially produced foods. For the investigated organic products (carrots, apples, salmon fillets and pork chops) no significant difference was found compared to... |

| Two types of milk, skim milk and non-standardized raw milk, were heat treated using direct heating by instant infusion pasteurization with treatment temperatures in the range from 72°C to 120°C and with holding times of less than 1 second. Indirect heating by HTST pasteurization (72°C for 15 seconds) was used for comparison. The inactivation of microorganisms reached at least the same level when using instant infusion pasteurization compared to HTST pasteurization. Changes in the physical-chemical properties were observed in the skim milk fractions of instant infusion pasteurized non-standardized milk, whereas for instant infusion pasteurized skim milk less influence from the treatments was observed. |

| The processing of meat products is regulated by a wide range of different national standards and regulations. Some countries have very strict regulations on additives for organic meat products. Standard setting often involves a balance between maintaining the purity and integrity of the organic system and ensuring that certain quality demands are met. Especially for meat this dilemma has been clearly recognized. Currently the most urgent challenge for the organic meat sector is to offer products with a high microbiological quality and safety without using critical additives like colouring agents or nitrite. The search for alternatives and alternative approaches to the use of nitrite in processed meat should be continued. Furthermore the discussion... |

| The drying behavior of fresh, matured, and frozen beef, marinated with 0.5% salt, 1% salt, salt and vinegar, and blind samples, dried at 70°C, was investigated. Weight and color (CIELAB) were measured and images of the samples were created with a hyperspectral imaging camera. Results show that the marinade and the type of beef influences the drying behavior of beef, but not the final color. Results from the hyperspectral imaging show that it is possible to build good fitting prediction models resulting in high R2 (min. 0.81, max. 0.98) and low RMSE (min. 0.08, max. 2.35) for moisture content, a* and b* values. |
