Additives in meat

It's incredibly difficult to find completely clean meat in stores anymore. The list of additives is getting long, and here we're looking specifically at meat products like cured meats, sausages, bacon and the like, which you would think would be fairly clean.

But the industry always manages to put in something extra, whether it's for durability, or texture, or to trick your eye into thinking it looks fresh and lively, and thus tempt us.

Cured foods, whether cured ham, salami, or other varieties, combine tradition and modern technology. Additives are used strategically to ensure shelf life, enhance flavor, and provide the right consistency, but there are also discussions surrounding some of them. Here's a deep dive into the most commonly used substances.

Sodium nitrite and sodium nitrate (E250/E251)

These are perhaps the most controversial additives in cured meats. Sodium nitrite (and nitrate, which is converted to nitrite) are absolutely essential in preventing the growth of Clostridium botulinum, the bacteria that can cause the deadly disease botulism. They also give meat the appetizing pink color that we associate with products like salami and cured ham.

Why it is used:

• Prevents dangerous bacteria from developing.
• Preserves the characteristic red color in meat.
• Gives cured meats the typical flavor that we love.

Discussions: The biggest sticking point in the discussion about nitrite is that it can form nitrosamines when it reacts with proteins in meat, especially at high heat (e.g. fried bacon). Nitrosamines can be carcinogenic, but the amount of nitrite used in cured meats is carefully regulated, and the addition of antioxidants (such as ascorbic acid) reduces the risk.

However, we produce large amounts of nitrite ourselves when we eat vegetables – more about that in a new article in a bit.

Salt

Salt is the cornerstone of curing. It has been used for thousands of years to preserve meat, and it is just as important today. Salt draws moisture out of the meat, creating an environment where bacteria cannot thrive.

Why it is used:

• Prevents bacterial growth and ensures long shelf life.
• Enhances flavor and provides the classic "savory" profile that cured meats are known for.
• Important for electrolyte balance, especially on a carnivorous diet.

Discussions: Salt has often been unfairly criticized as a health hazard, but for those who eat a meat-based diet, salt is essential for fluid balance, nerve function, and general health. Salt also starts to taste toxic very quickly if you ingest too much, so this tends to regulate itself in terms of both over- and underdosing.

Ascorbic acid (vitamin C) and sodium ascorbate

These antioxidants play a discreet but important role in cured meats. They are often added along with nitrites to stabilize color and prevent oxidation of fats.

Why it is used:

• Reduces the risk of nitrosamines by blocking unwanted chemical reactions.
• Helps preserve the fresh red color of the meat.
• Improves product durability and quality.

Discussions: Ascorbic acid is considered safe and natural, and there is little controversy surrounding its use, especially since it is also found naturally in many foods in both the animal and plant kingdoms.

Sugar (dextrose, sucrose, glucose)

Sugar is not used to make cured meats sweet, but to feed the good bacteria that drive the fermentation process in products like salami.

Why it is used:

• Food source for lactic acid bacteria, which lowers pH and makes products safe to eat.
• Contributes to the development of the sour taste in fermented cured meats.
• Balance the taste and tone down the salty impression.

Discussions: For many people who avoid sugar, this may seem unnecessary. However, it is worth noting that the amount of sugar in finished cured meats is minimal, as most of it is consumed during fermentation.

Lactic acid bacteria (starter cultures)

These are the little heroes of fermented cured meats. Bacteria that Lactobacillus og Pediococcus added to ensure a controlled and safe fermentation process.

Why it is used:

• Produces lactic acid, which lowers pH and inhibits harmful microorganisms.
• Gives cured meats their characteristic sour taste.
• Ensures consistent quality and taste in every batch.

Discussions: This is considered a safe and natural method, and many traditional producers use natural bacterial cultures from the environment instead of added starter cultures.

Phosphate

Phosphates are often used in emulsion sausages and spreads to bind water and improve texture.

Why it is used:

• Retains moisture and prevents products from drying out.
• Gives a smooth and juicy consistency.

Discussions: Phosphates have been controversial because they can affect the calcium balance in the body when consumed in high amounts, but the amounts in cured meats are low and considered safe.

Paprika extract and carmine (E120)

These natural dyes are used to give cured meats an appealing red color.

Why it is used:

• Gives a visual impression of freshness and quality.
• Used especially in spicy products such as chorizo.

Discussions: Paprika is a nightshade, a fruit from the nightshade family. Many people have reactions to peppers and other nightshade plants, and an extract is by definition a highly concentrated version of a plant.

Liquid smoke

Liquid smoke is a modern substitute for traditional smoking and is added to give cured meats a smoky flavor.

Why it is used:

• Effective for imparting smoke flavor without time-consuming smoking processes.
• Can be more consistent than traditional smoking.

Discussions: Some people prefer traditional smoking because it adds more depth and complexity to the flavor.
