Food

Forward-looking management in the food and nutrition industry is closely bound up with an ecological approach to of the value chain as a whole. This extends from environmentally sound agricultural production through food processing, packaging, transportation, and all the way to the consumer.


Technological innovations from Germany in this area have contributed to
• making the fullest possible use of raw materials,
• reducing water and energy consumption in foodstuff manufacture and finding valuable uses for the byproducts and waste products,
• optimizing the amount of material used and recycling options for food packaging,
• the use of energy-saving or climate-friendly cooling systems in transportation vehicles and supermarkets.
“White” biotechnology is an important factor in research and development in the food industry. This database contains a wide range of illustrative projects e.g.:
• Recovery of material from pomace from fruit and vegetable processing for use in functional foods.
• Production of egg products in which cholesterol-containing saturated fats are replaced by unsaturated vegetable oils.
Technical process optimizations are also covered:
• Application of a high-pressure process for careful, energy-saving food preservation.
• Reduction in the downtime of technical plant by using sensor systems to monitor coating buildup in machines.
• Development of methods of heat use and energy saving in sugar processing, bakeries and the meat processing industry.

Link-IconBagasse/Biomass project using combined heat and power with a total capacity of 26 MW in India
This cogeneration project with a total capacity of 26 MW aims at the expanded use of the by-product “bagasse” obtained in the manufacture of sugar. It is planned to utilize waste products as fuel from the own production site but also from another sugar cane mill. The project will provide the steam and the electricity needed for the sugar production including adjoining houses. The surplus is feeded into the national network. The project is viewed as exemplary test for future CDM projects.

Project-IconCoating sensor to reduce environmental pollution in production lines of food industry
In order to reduce downtimes for technical installations in the German milk and beer industries, a sensor system for the monitoring of the formation of deposits in production units and the identification of appropriate cleaning measures has been developed and successfully tested. The system comprises interdigital sensors and a multivariate signal evaluation facility. Expand…

PDF-IconCoatings for environmentally friendly drying systems in the foodstuffs industry
The German language brochure contains information on the development of a coating for the interior walls of drying installations used in the foodstuffs industry. The coating system reduces the tendency of products to adhere to these walls, thereby reducing both costs and environmental pollution. Environment-friendly agents can be used for cleaning purposes – this generates savings in energy use, waste production and water consumption.

Project-IconCoatings for plants for environmentally sound drying in the foodstuff industry: materials development (Part 1)
The production of anti-sticking coating materials based on inorganic-organic nanocomposites that can be applied with wet chemical application methods to stainless steel surfaces, and adhere very well to these substrates, was successful. High-fat whey was even able to be removed nearly completely from coated lab samples with very smooth anti-sticking surfaces using compressed air. Expand…

Project-IconConcentration and isolation of high quality lacto- and phytoproteins in dairy product waste and various starch-containing residues by means of preparative isoelectrically focussed foam concentration
Isoelectrically focussed foam concentration is an effective technique for concentrating proteins in aqueous solutions. After minor modification, the technique can also be used for the isolation of enzymes and antibodies and for protein purification. Expand…

Project-IconConstruction and operation of a plant for anaerobic preliminary treatment of wastewater from the fruit juice industry
With the help of an anaerobic pre-treatment plant, the process wastewater of Lindavia Fruchtsaft AG could be purified to concentration levels of municipal wastewater in an economical and stable operation. Important factors were the reduction of COD-charge and the reduction in quantities of sludge passed on to the purification plant. The selected design of the equipment has a methane reactor designed as an UASB-reactor with a separate acidification stage. Expand…

PDF-IconConstruction of a plant for the biological treatment of highly loaded waste water and model application in a viticultural enterprise
Principal purposes of the project were the development of an adapted technical solution and the testing of a new catalyst material from the Siberian Angarsk, which would possibly permit a higher degradation of the COD at purification plants.

Project-IconContinuative utilisation of the material potential of molasses and molasses draff for the production of natural flavourings - here 2-Phenylethanol: Bioprocess optimisation - Focus on Pervaporation (Part 2)
In membrane screening, a composite membrane was found to be the most suitable for product separation. Further, the mathematical model that has been developed allows the quantitative description of pervaporation at laboratory and pilot scales. The overall process composed of the pervaporation and the bioprocess, can also be described reliably in the lab scale. Expand…

Project-IconContinuative utilisation of the material potential of molasses and molasses draff for the production of natural flavourings - here 2-Phenylethanol: Bioprocess optimisation – Focus on Biology (Part 1)
An integrated bioprocess for the microbial production of 2-phenylethanol (2-PE) from L-phenylalanine with in-situ product removal (ISPR) by organophilic pervaporation was developed. The technology has been tested successfully at laboratory scale. Insight into the product spectrum and profitability analysis was obtained. Expand…
