Microbiological validation for the quality assurance of hygienic and aseptic filling plants
High microbiological requirements are often put on hygienic and aseptic filling plants used by the food and pharmaceutical industries. These microbiological requirements depend on the specific product and the desired shelf-life. We can assist you with plant/machinery selection, classification in accordance with VDMA, and contractual agreements with suppliers and customers.
In addition to the technical qualification of plants/machinery, the effectiveness of hygienic and sterile processes must be validated. We can assist you with factory acceptance tests (FATs), site acceptance tests (SATs), and carry out any necessary microbiological tests. We measure the effectiveness of sterilization systems for machines, products, and packaging using challenge tests, media-fills, and stand tests in accordance with the applicable regulations (VDMA, GMP, and FDA). We also undertake periodic re-validations.
If you require assistance with carrying out microbiological validations for process development, process optimization, or machine/plant procurement, then please get in touch with us.

Designing recyclable packaging using shelf-life models
What is the shelf-life of a food product packed in a given, recyclable packaging? In order to answer this question quickly and decisively we develop shelf-life simulation models. These models are especially helpful against the background of the new German Packaging Act and the need for companies to change to different packaging materials. The simulation models obviate the need for time-consuming tests and show the required barrier properties for the respective food product. Important chemical spoiling processes such as autoxidation, photooxidation, and water absorption/loss can also be taken into account. We can reliably predict the shelf-life of your products in new and improved recyclable packaging for differing packaging scenarios. You are welcome to contact us! We can help you design recyclable packaging specifically tailored to your products.

Prof. Dr. Jessica Freiherr appointed professor at the Friedrich-Alexander Universität Erlangen-Nürnberg
Prof. Dr. Jessica Freiherr was appointed W2 Professor of Neuroscience of Sensory Perception at the University Clinic of the Friedrich-Alexander-Universität Erlangen-Nürnberg on 1 January 2019. At the Fraunhofer IVV she will continue to lead the MultiSense group. In contrast to conventional sensory analytics with the focus on odor, taste, and texture, she and her team study the holistic perception of products. The combination of multisensory parameters enables the customized optimization of product properties. In addition, the acceptance of and preference for staple and luxury foods and cosmetics and the initial decision to purchase is investigated based on the product packaging.
As an expert in the interdisciplinary research area of multisensory perception, Prof. Freiherr will continue to help shape our Campus of the Senses initiative and the digitalization of human sensory perception.

Cleaning 4.0 in the meat processing industry – higher efficiency using robots and simulation software
Visit us at the leading international fair of the meat industry IFFA from 4 to 9 May 2019 in Frankfurt. We will be demonstrating how machinery used for meat processing can be efficiently cleaned using new technologies. A versatile, mobile cleaning robot accomplishes this, with simultaneously time and cost savings. Innovative simulation software is also allowing the rapid and effective design of spray cleaning systems. It guarantees effective and precisely targeted cleaning. It saves time-consuming tests in the plant design phase.
Both technologies will be presented in the VDMA Technology Lounge in Hall 11.1, Stand B41. You are also welcome to contact us before or after IFFA. Do arrange an appointment with us!

Technofunctional proteins from plant processing residues
Our industrial extraction and fractionation processes expand the utilization of protein-containing byproducts. Large quantities of such byproducts arise when processing plant raw materials, but up until now these have remained largely unused. The residues from the recovery of rapeseed oil, for example so-called rapeseed meal and rapeseed press-cake, are in part used for animal feed. However, this use is limited due to bitter substances and poor digestibility.
The collaborative TeFuProt project is investigating the recovery of proteins from residues from rapeseed oil production and their use in a variety of products. The aim is to use a combination of different extraction and modification processes to produce protein preparations having customized technofunctional properties for specific applications. We are also investigating how to optimally incorporate these proteins into formulations for different industries. For example, proteins are being incorporated into paints, lacquers, cleaning agents, lubricants, adhesives, and polymers as either a base component or additive.
