New Approaches to Safe, High-Quality Meat Products
Research Project Investigates Further Reduction of Nitrite and Nitrate in Meat Products
Advertisement
How can nitrite and nitrate levels in meat products be further reduced without compromising quality and safety? Research teams from Germany and Belgium are addressing this question in a Joint Industrial Research (IGF) project coordinated by FEI as part of the transnational CORNET funding program. Against the backdrop of stricter EU regulations, they are investigating the effects of lower additive levels on color, aroma, taste, and microbiological safety, as well as the formation of potentially carcinogenic nitrosamines. The goal is to develop practical solutions for high-quality and safe meat products with significantly lower levels of nitrite and nitrate.
Less Nitrite and Nitrate: New Approaches for Safe and High-Quality Meat Products
Whether it’s salami, raw ham, or cooked sausage: for many consumers, the typical reddish color and the characteristic cured aroma are integral to these products. Nitrite and nitrate play an important role in this. These additives, which have been used for decades, not only enhance color and flavor but also act as antioxidants and inhibit the growth of pathogenic microorganisms such as Clostridium botulinum. In this way, they contribute to the quality, shelf life, and microbiological safety of meat products. However, under certain conditions, nitrites can form so-called nitrosamines, which are considered potentially carcinogenic. Nitrate can be converted into nitrite by microorganisms in the product or in the human body. Reducing the amounts of added nitrite and nitrate as much as possible without losing their beneficial technological effects is therefore a particular challenge.
Stricter legal requirements for nitrite and nitrate in meat products have been in effect in the EU since October 2025: The permitted levels of addition have been lowered, and at the same time, maximum limits for their residual levels in products have been introduced for the first time. Some EU countries are even aiming for even lower levels. Manufacturers are therefore faced with the question of how much further the use of nitrite and nitrate can be reduced in the future without compromising the color, aroma, taste, or microbiological safety of the products. This is precisely the focus of a current project by the Industrial Joint Research Program (IGF), coordinated by FEI as part of the transnational funding initiative CORNET (Collective Research Networking): Research teams from the University of Hohenheim and the Max Rubner Institute in Kulmbach, as well as KU Leuven and Ghent University in Belgium, are jointly investigating how the levels of nitrite and nitrate in heated and unheated meat products can be further reduced. The focus is explicitly not only on the requirements that will take effect in 2025, but also on reductions well below the maximum levels currently permitted.
To this end, the researchers are closely examining both the recipes and the manufacturing processes of various meat products. They are investigating how lower levels of nitrite and nitrate affect color and appearance, curing aroma and taste, as well as microbiological safety. At the same time, they are analyzing the influence of product composition and processing conditions on the formation of nitrosamines. Based on these findings, approaches will be developed to further reduce nitrite and nitrate levels without compromising the quality and safety of the products. In addition, research is being conducted on the potential health effects during the gastrointestinal digestion of processed meat products, particularly sausages.
Such findings are particularly important for small and medium-sized enterprises in the meat products industry. They can help adapt recipes and manufacturing processes to achieve even lower levels of nitrite and nitrate while maintaining product quality and safety. The industry is closely involved in the project: A total of 15 companies are participating in the project’s advisory committee, including nine small and medium-sized enterprises. They contribute their practical experience and specific questions, thereby supporting the transfer of research results into industrial applications. Manufacturers of ingredients, additives, and starter cultures can also benefit from the results. At the same time, the project provides companies with knowledge that will enable them to respond to potential future regulatory changes and varying requirements in European markets.
