Peter Muranyi, Senior Scientist and Business Unit Manager for “Food“, has a PhD in Food Engineering and a M. Sc. Degree in Food Technology and Biotechnology. He has been working at Fraunhofer IVV (Institute for Process Engineering and Packaging) for over 14 years and his research focus is on food shelf life prolongation by developing product-specific preservation approaches and packaging solutions.
Dr. Muranyi is specialised in food and packaging microbiology as well as food quality assessment and has long lasting experiences in the field of sterilization of packaging material by various physical (e.g. gas plasma, pulsed light) and chemical methods (e.g. hydrogen peroxide, peracetic acid) and the development of microbiological validation methods. His current field of work is dedicated to antimicrobial active packaging with natural preservatives.
Dr. Muranyi was involved in various National and European research projects concerning the topics active/intelligent packaging and surface sterilization.
What will you adress att Packbridge Research Forum?
What are you currently working on at Fraunhofer?
- “That packaging is a very important part in the food value chain is hardly a surprise. Much of it is made from fossil-based plastics, which the general public unfortunately often associates with a negative environmental impact. Bioplastics are being considered in this context but, so far, it has mostly been about mono-materials which don’t meet the standards required for food.
- We are working to find solutions with biomaterials and trying to develop product-specific packaging solutions using various models. Currently we are looking at modified biopolymers based on starch and wheat proteins, with which we want to achieve oxygen barriers comparable with fossil materials”.
How far have you come in this work?
- “We have just developed a material based on wheat protein which we have tested as a coating on film, and the laminate we have created can be used for a variety of packaging solutions. Interestingly, this barrier material can be removed by enzyme based cleaners which means that the package can be reused.
- “So, via a by-product of the food industry, we have created an opportunity for the packaging industry, and I hope to tell you more about it on 23 May”.
