OPTIDRYBEEF

Safe and qualitative dry aging of beef

Problem and opportunity

OPTIDRYBEEF is an interdisciplinary project which will focus on process innovation and translation in the development of a specific food processing technology, with the potential to impact a broad range of stakeholders in the meat chain both on a national and international level: safe and qualitative dry aging of meat.

Several questions have arisen in the meat industry regarding dry aging of beef in recent years. These questions generally refer to gaining more insight into the characteristics of dry aged beef, more specifically:

  • the sensory quality, 
  • safety, 
  • the ideal process conditions 

All in order to bring a high quality and safe product into the market. OPTIDRYBEEF focuses on a comprehensive and integrated evaluation of the dry aging process to introduce dry aged beef as a high-quality product into the meat producing chain to strengthen the meat industry at the level of butchers, restaurants, caterers and supplying industry.

Research approach

This project aims at providing a comprehensive review of the dry aging process. Thereby, critical process conditions will be laid down within which it is possible to produce a safe, tasty and economical dry aged product.

  • For this purpose, a variety of dry aging processes will be carried out by the participating partners. Within these experiments, the parameters of dry aging chambers (relative humidity, temperature), the duration of aging and choice of the raw materials (e.g. type of animal, fat cover) will be varied.
  • In addition to the recording of all process parameters, microbiological and sensory monitoring of the meat during the dry aging process will be carried out. The likelihood of pathogens (Salmonella, Shigatoxin-producing E. coli (STEC) and Listeria monocytogenes) to survive and/or grow during the dry aging process and in consumer packaging will be determined for evaluating the safety of the process.
  • Furthermore, for this purpose, the hygienic status of the dry aging chambers will be characterized. To get more profound insights on the impact of dry-aging on aroma formation potential, taste panel analyses will be supported by chemical- analytical measurements of meat composition and quality, and detailed GC-MS analyses of the aroma profile will be conducted.
  • In addition to optimizing the process, further processing of crust is examined to improve the economics of the process.

The overall expected outcome of the present project is to provide the participating companies and the European food sector with data supporting the production of high-quality and safe dry aged meat products.

Market sector targeted and expected results

Dry aged beef is a high-quality and highly priced product with a strongly increasing production rate. This trend will be pushed forward by a change in consumer demand towards high-quality products. The meat and associated supply industry of which the majority is SME´s, will be supported by this proposal to address this demand and to take advantage of this.

  • Due to this project the machine builders will gain more knowledge about the influence of production parameters on safety and quality of the end product and can therefore better advice there customers and set an efficient working regime for their dry aging chambers.
  • The beef/meat producers can use the information, to optimize the production process to achieve a more economical process, or to start the production of dry aged beef or meat in general. 
  • Furthermore, this project will contribute to a better image for the whole meat industry, since a more tender meat product with an exclusive aroma can be produced if the dry aging process is applied correctly.

project partners

OPTIDRYBEEF is a collaboration between 2 associations, Flanders’ FOOD (Belgium) and FEI (Germany). 6 Research and Technology Organisations, all of which have great experience in food science and technology, and meat in particular, will perform the scientific work (UGent, KULeuven, ILVO (Belgium) and DIL (Germany)). A strong industrial leadership will be reflected by the inclusion of 18 companies (12 SMEs) within the UC both from Germany and Belgium.

Flanders' FOOD and FEI (Research Association of the German Food Industry) manage and coordinate the project. The scientific research will be conducted by different research groups:

DIL

The German Institute of Food Technologies (Deutsches Institut für Lebensmitteltechnik e. V. – DIL) has been working as an industrial and research institute for product and process development in food production since its foundation in 1983. It is supported by more than 160 members from the fields of food and compound feeds production, mechanical engineering, metrology and process engineering. It has a staff of more than 170 members who are dedicated to linking science and practice in order to support SMEs in the development of innovative ideas for a successful future.

 

Ghent University, Laboratory of Animal Nutrition and Animal Product Quality (Lanupro)

The Laboratory of Animal Nutrition and Animal Product Quality (Lanupro) has extensive experience in measuring and assessing the quality of fresh meat (composition, sensory and technological properties, physicochemical shelf life and nutritional value) and the influence of biochemical and zootechnical factors. With regard to beef, Lanupro has participated in the past in several national and international projects concerning the influence of the animal type, feeding and slaughter technology on meat quality (e.g. the influence of the dikbilfenotype in the Belgian Blue breed on the tenderness, eating quality, fatty acid composition, color and color stability).

 

KU Leuven - Research for Technology and Quality of Animal Products (KUL–Meat)

The research activities of KUL – MEAT (KU Leuven Technology Campus Ghent) focus on meat, especially processed meat. The lab includes a pilot plant where various types of meat products can be prepared under strictly controlled conditions in accordance with the industrial standard. The laboratory is fully equipped for the analysis of meat and meat products, e.g. microbiology, and (bio) chemical, physical, micro- and macroscopic (quality) aspects of meat. The research group is part of LFoRCe (Leuven Food Science and Nutrition Research Centre). Within the framework of the VIS-TD project “New practices and technologies for innovations in the meat and meat processing industry”, the group acted as the Flemish Advisory Centre on Meat (VLAV).

 

Ghent University, Department of Veterinary Public Health and Food Safety (UGent-V&V)

Prof. De Zutter has extensive experience in the epidemiological investigation with a focus on foodborne pathogens through the production of fresh meat. His laboratory is affiliated to the Department of Veterinary Public Health and Food Safety of the Faculty of Veterinary Medicine of the University of Ghent. The laboratory has great experience in evaluation of methods to quantify and isolate foodborne pathogens.

 

KU Leuven - Research Unit Molecular Odor Chemistry (KUL-Aroma)
