International Workshop “Safe Feed for Healthy Food“

On 24 November 2011, the international workshop “Safe Feed for Healthy Food” took place at the Research Institute which was organised by by Prof. J. Zentek, Freie Universität Berlin, Germany, Prof. P. Häggblom, National Veterinary Institute (SVA), Uppsala, Sweden, and Dr. Alexander Feil, IFF, Braunschweig, Germany. 23 participants and 11 speakers took active part in the event.

From the view of the compound feed production especially mycotoxins and salmonella represent a significant risk for the animal health and because of the carry over effects also for the human health. Cases of damages may lead to essential economic losings for the compound feed producer. Optimised operative strategies concerning the handling with these contaminants require beside the early identification an efficient decontamination. This assumes an effective system of control and monitoring including suitable methods of analysis, an adapted information management and founded knowledge in procedural possibilities and limits.

The workshop includes the following findings of the FP6 research project “BIOTRACER IP”, presented by international accepted experts:

•    Hazard assessment for imported and local raw materials concerning the contamination by aflatoxines, ochratoxines and salmonella
•    Improved measures of sampling and analytics during the process for these contaminants.
•    Development of a simulation tool for salmonella.

The workshop was supplemented by the experiences of the Research Institute of Feed Technology concerning the effects of technological decontamination methods including the acid application.

The participants were especially impressed by the video “Sampling For Contaminants In Animal Feed” which was established in the frame of the research project. It illustrates the latest findings on the sampling of mycotoxins and salmonellae. The video can be found at YouTube.

Besides the presentation of the newest scientific knowledge the workshop offers the opportunity of important and informative networking and exchanging of ideas between industry, monitoring devices and science.

IFF Practical Course "Basic steps of industrial compound-feed production"

Also in this year, the two-day practical course “Basic steps of industrial compound-feed production” met a good resonance. The course took place at the Research Institute of Feed Technology on 11 and 12 October in German language. 27 participants from the national and international feed industry and the machinery industry learnt not only the performance of the receiving control but also basics of the processing fundamental processes comminution, mixing and dosing. Also essential measuring and inspection methods for characterizing relevant material properties were imparted. In practical trainings the participants could deepen the imparted subjects for a more intensive understanding.

After this practical course, participants will be aware of the major parameters and thus be able to better control the basic steps in compound-feed production.

IFF Workshop "Appropriate storage and use of liquids in the compound-feed production”

On 27 September 2011 the IFF Workshop concerning the subject “Storage and use of liquids” took place. Because of the various common but also alternative liquids as well as different process and plant parameters, it arises a wide range of subjects and applications concerning the use of liquids in the compound feed production: Beginning with the receipt and storage of liquids and ending with their application on finished products.
Furthermore, measures are required to ensure the quality in the production of liquid single feed stuff. These measures should guarantee a traceable documentation of purchase of the raw materials, the production and processing until dispatch and vice versa.
To cover this range of subjects, the workshop had been designed by contributions of well-respected speakers of the economy, who gave important advices of the daily work to the 34 participants about the following subjects:

•    Planning and building of plants for storage purposes
•    Dosing of liquids
•    Material properties
•    Management of production and quality
•    Technological aspects of applications of liquids in mixers
•    Possible applications of a continuous vaccum coater

The workshop was completed by the presentation of the results of the IFF-research project regarding the addition of liquids in the main mixer as well as the property of glycerin concerning the technological handling in compound-feed formulations.
Additionally, the Fraunhofer Institut for Process Engineering and Packaging IVV presented their research results concerning use of emulsions in alternative applications.

Her short review

As a part of the project “FEED-TO-FOOD” (FP7-REGPOT-2007-3 "Reinforcement of Feed to Food Research Center at Institute for Food Technology of the University of Novi Sad") which includes the exchange of research experience, the first longer visit to IFF was from August 16^th to September 11^th. In the period of the visit, I was introduced with the works and almost all activities of the institute, including laboratory work and some pilot plant work which are carried out under current projects. I felt all the time as a member of the collective because I had opportunity to be present at all institute meetings concerning work at last and future weeks. Also I got an opportunity to present my research work as well as the work of my institute, particularly the department of Feed and Animal Products. All the time, we discussed about possibilities of further cooperation and possible results which can be published in some journals to get references for future European projects. Main topics were methods used in determination of homogeneity and working accuracy, as well as about some investigations in the area of feed pelleting process and liquid addition. We also talked about the contribution in the current FP7 proposal in area of feed safety and quality and made some comments and suggestions. In the period of the stay, I visited the Friedrich Loeffler Institute (FLI), their facilities and introduced their field of research and also AGRAVIS, local feed producer, who is a part of the Raiffeisen Company. A one-day visit to Hanover Messe on September 8^th was aimed to meeting with Dr. Steinkamp from the Deutsches Institut für Lebensmitteltechnik (DIL) and after discussion we established a good base for future cooperation.  

Finally, I can say that my visit was successful and fruitful and that our two institutes can do more in future in the field of feed technology not only as a part of the project “FEED-TO-FOOD” but in the other kind of projects.

Four young researchers from Novi-Sad (Serbia) visited IFF

Within the project FP7-REGPOT-2007-3 "Reinforcement of Feed to Food Research Center at Institute for Food Technology of the University of Novi Sad" four young researchers visited the Research Institute of Feed Technology of IFF. A short summay of the 14-day stay as well as impressions and experiences of the young scientists are compiled as follows: 

With this article we would like to share our impressions about IFF Institute in Braunschweig. We are Bojana Kokic, Radmilo Colovic, Djuro Vukmirovic and Dusica Ivanov, young researchers from Institute for Food Technology in Novi Sad, Serbia, department for Animal Products and Feed Technology. IFF Institute is our associate institute on FEED-TO-FOOD FP7 project, funded by European Commission.

The reason for this two week visit was to participate on basic course “Fundamentals and new developments in feed-compounding technology“, but also introducing with all equipment and physical analysis that are conducted on IFF Institute. The least that we can say is that this visit was useful and that it fulfilled all our expectations.

The course was very well organized. The lectures were focused on practical issues and supported by scientific data that was originally from IFF experiments. We also got some new information about legislations and EU laws, which will help us to understand functioning of European Union better. The lecturers had great knowledge in their areas and they were ready to answer on all of participants´ questions.  

In second week we were introduced with all process equipment, such as extruders, expanders, pellet machines, various types of mills, etc. That was especially interesting for us because of the fact that we have the same devices in our pilot plant, and that we are planning cooperation on same frame work projects in future.

We were also shown physical laboratory equipment and methods which will help us to improve our laboratory and to implement some new analysis. A lot of literature and scientific papers that we also got would show us in which direction our experiments should proceed.

At the end, we could not forget visits to the “Friedrich-Loeffler-Institut (FLI)”, “Burg Warberg”, “Feed Mill Agravis Braunschweig”, “DMSB” International Technical School for Process Construction and Process Engineering, “MEGA Haldensleben” and “Schaumann Eilsleben”. Not less important are contacts that we made with a lot of our colleagues from areas related to feed production.

We would like to express our gratitude to our hosts for hospitality and well organised visit to Braunschweig and we are inviting them to visit our institute!

Substance data base on the dust-formation behaviour of single feeds, additives and feed mixtures

In the frame of the research project “Explosion hazards”, that was made possible with funding from the Federal Ministry of Economics and Technology via the German Federation of Industrial Cooperative Research Associations “Otto von Guericke” e.V. (AiF), a material data base was developed in which investigation results are made available on the dust-formation behaviour under different conditions on basis of the relevant identification of the substances used in the grain cultivation and feed industry.

The selection of the materials are geared to the already available data base (BIA GESTIS-STAUB-EX data base, BGIA - BG-Institute for Occupational Safety and Health) and is a supplementation to the fire and explosion characteristics.

The data base is available with immediate effect and can be supplemented dynamically.
