For years, the reduction of nitrifying agents<\/strong> (nitrates and nitrites) in the meat industry has been a topic of discussion. Finally, on October 9, 2023<\/strong>, the European Union published Regulation 2023\/2108<\/a><\/strong>, which came into effect on October 29, 2023<\/strong>, and will require many meat product manufacturers to modify their formulations.<\/p>\n

Although companies have a two-year adaptation period<\/strong> (until October 9, 2025), this regulation will bring significant changes to the formulation of numerous meat products in Spain<\/strong>. The permitted levels of nitrites (E-249: potassium nitrite and E-250: sodium nitrite<\/strong>) and nitrates (E-251: sodium nitrate and E-252: potassium nitrate<\/strong>) will be reduced. Additionally, for the first time in the EU<\/strong>, mandatory regulation of residual nitrite levels<\/strong> and indicative nitrate levels<\/strong> has been established.<\/p>\n

It is important to note that these new nitrate and nitrite limits<\/strong> will be mandatory starting October 9, 2025<\/strong>. However, meat products marketed before this date can remain on the market until the end of their shelf life<\/strong>.<\/u><\/p>\n

Below, we will detail the changes in the maximum permitted levels of nitrifying agents and the natural alternatives<\/strong> offered by Amerex Ingredientes<\/strong>.<\/p>\n

What Is the Technical Functionality of Nitrites and Nitrates in Meat Products?<\/h2>\n

To understand this regulation, it is essential to know the technological function<\/strong> of nitrifying agents in meat products, as nitrites and nitrates play a key role in the food safety of meat products.<\/p>\n

Their main function is to inhibit the growth of pathogens such as Clostridium botulinum, preventing the development of dangerous toxins. In addition, they contribute to the stability of the colour, aroma and flavour of meat products, thanks to their antioxidant and technological properties. This dual function (preservation and sensory quality)<\/strong> makes them difficult to replace, especially considering the risk of contamination by Clostridium<\/strong>, one of the most dangerous bacteria<\/strong> in the food industry.<\/p>\n

As a result, nitrifying agents are widely used in the meat industry<\/strong>.<\/p>\n

What New Reference Does the Reform Introduce for Residual Levels of Nitrites and Nitrates?<\/h2>\n

Initially, the European Commission proposed mandatory residual values for both nitrites and nitrates. However, in the final version of the regulation only nitrites have mandatory residual limits<\/u><\/strong>, since nitrates have indicative values only<\/p>\n

If indicative nitrate values<\/strong> are exceeded, meat companies must investigate the cause<\/strong>. This could create conflicts with health authorities<\/strong>, as the application of penalties or requirements<\/strong> will depend on the criteria of each regional authority<\/strong> in Spain<\/strong>.<\/p>\n

 <\/p>\n

What Are the New Permitted Levels of Nitrates and Nitrites?<\/h2>\n

 <\/p>\n

Below, we indicate what the new nitrate and nitrite levels will be for the different meat products, in this case, meat companies will be able to choose between two mutually exclusive options for use:<\/p>\n

1.\u00a0\u00a0\u00a0\u00a0\u00a0 General Use of Nitrifying Agents in Meat Products and Certain Meat Preparations<\/h3>\n

The authorised uses and maximum quantities of nitrites that may be added during processing are as follows:<\/p>\n\n\n\n\n\n\n\n\n\n

As mentioned above, it should be borne in mind that the residual values are mandatory.<\/u><\/strong><\/p>\n

As far as nitrates (E-251 – 252) are concerned, their use is still limited in several categories:<\/p>\n\n\n\n\n\n\n\n\n\n

Residual values for nitrates are only indicative. However, if exceeded, companies must investigate the cause.<\/p>\n

2.\u00a0\u00a0\u00a0\u00a0\u00a0 Use of nitrifiers in traditional meat products (Category 08.3.4):<\/h3>\n

Derogations exist for traditional cured products (In Category 08.3.4 \u2018Traditional cured meat products with specific provisions for nitrites and nitrates\u2019), such as cured ham, cured shoulder, cured loin, cured beef jerky, chorizo and salami. The new regulation allows flexibility with the mention of \u2018and other similar products\u2019.<\/p>\n

Here are the new limits:<\/p>\n

<\/h2>\n

Why has it been decided to modify the nitrifiers regulation and reduce their use?<\/h2>\n

As we mentioned at the beginning of this blog, the need to reduce the use of nitrifiers has been discussed for several reasons.<\/p>\n

Firstly, already in 2017 the European Food Safety Agency (EFSA) assessed the safety of nitrates and nitrites in food, concluding that the permitted levels were safe. However, it identified that certain population groups could exceed the Acceptable Daily Intake (ADI) for nitrites<\/strong>. This, coupled with concerns about the formation of nitrosamines, prompted the European Commission to reduce the permitted levels.<\/p>\n

European countries such as Denmark already applied stricter limits, which made it difficult to export Spanish meat products to these markets. Pressure from these countries prompted the revision of the regulations, culminating in the publication of Regulation 2023\/2108.<\/p>\n

In the case of the Spanish meat sector, intensive work has been carried out with the Spanish Agency for Food Safety and Nutrition (AESAN) and the European Commission to achieve a balance between food safety and industrial viability, as the microbiological risk of contamination by Clostridium<\/em> is not a minor issue and it is essential to ensure consumer safety.<\/p>\n

As a result of these negotiations, the limits set in the final regulation were more reasonable and adaptable to the needs of the industry.<\/p>\n

Nevertheless, with the entry into force of Regulation 2023\/2108<\/a>, Annex II of Regulation 1333\/2008 and the Annex of Regulation 231\/2012 have been amended, establishing new limits for nitrifiers in meat products within the EU.<\/p>\n

What Nitrite Substitutes Does Amerex Offer?<\/h2>\n

At Amerex<\/strong>, we are experts in natural preservation<\/strong> and have developed alternative solutions<\/strong> to reduce or replace nitrifying agents.<\/p>\n

In our case, our technology is based on the use of starters. Our product Biamex NC<\/u><\/strong>, has a very innovative technology<\/em> for the generation of the typical colour that nitrifiers would provide. In this way, thanks to a fixation reaction of the meat\/fish protein itself, you can achieve an optimal replacement of nitrates, nitrites and\/or nitro salts. In addition, this product incorporates another of our strains of ferments specialised in the action against sporogens such as clostridium botulinum.<\/em><\/p>\n

We have several success stories of this product together with other preservatives that can help you to reduce the use of nitrifiers in order to adapt to legislation. We have both preservation and organoleptic technology so that your product is safe and organoleptically optimal for the consumer.<\/p>\n
