Everything you need to know about curing meat safely, consistently, and compliantly — from curing salts and fermentation to drying, hygiene, and best practice.
Meat curing combines tradition with science. Whether you’re producing fresh sausages, dry-cured salami, bacon, or whole-muscle products, understanding the fundamentals of curing is essential for food safety, quality, and repeatability.
This Meat Curing FAQ answers the most common questions asked by butchers, curers, and food producers, from beginners to experienced professionals.
What is meat curing?
Meat curing is the process of preserving meat using salt, curing agents, time, and controlled conditions to improve safety, flavour, texture, and shelf life. Curing can be done through dry curing, wet curing (brining), fermentation, smoking, or a combination of methods.
Cured meat products include salami, chorizo, pancetta, bacon, ham, pastrami, and many traditional regional specialties.
Why is curing meat done?
Curing serves several key purposes:
Food safety: limits the growth of harmful bacteria
Preservation: extends shelf life
Flavour development: creates distinctive cured flavours
Colour stability: produces the characteristic cured pink/red colour
Texture improvement: firms meat and improves sliceability
Modern curing combines traditional techniques with controlled ingredients and processes to ensure consistent, compliant results.
What is curing salt?
Curing salt is regular salt blended with a carefully controlled amount of curing agents such as sodium nitrite (E250) or potassium nitrate (E252). It is specifically formulated for meat curing and must not be confused with table salt.
Curing salt helps improve safety, colour, flavour, and shelf life, and should only be used according to precise recipes and manufacturer instructions.
What’s the difference between dry curing and wet curing?
Dry curing: Salt, curing agents, and spices are rubbed directly onto meat. Common for salami, pancetta, and whole muscle cures.
Wet curing (brining): Meat is submerged in or injected with a salt solution. Used for bacon, hams, and pickled meats.
Both methods rely on accurate salt levels and controlled conditions to work safely.
What’s the difference between E250 and E252?
The main difference is how quickly they work.
E250 (sodium nitrite) works immediately
E252 (potassium nitrate) works slowly by converting into nitrite over time
Nitrite is ideal for short cures and cooked products, while nitrate is used for long dry curing and extended maturation.
Do I need curing salt to cure meat?
For commercial production, yes.
Curing salts help control pathogens, ensure predictable fermentation, and produce consistent results. While traditional curing without additives exists, modern food safety standards strongly favour the use of regulated curing salts and starter cultures, especially when products are sold.
What role does salt play beyond preservation?
Salt does more than preserve meat:
Draws out moisture
Firms texture
Enhances flavour
Helps proteins bind (important for sausages)
Supports fermentation by controlling microbial activity
Correct salt levels are essential — too little risks spoilage, too much affects taste and texture.
What are starter cultures and do I need them?
Starter cultures are beneficial bacteria added to fermented products like salami. They:
Lower pH safely and predictably
Improve flavour consistency
Reduce fermentation risks
Support compliance and repeatability
For beginners and commercial producers, starter cultures are strongly recommended.
Can curing salt be used instead of regular salt?
No.
Curing salt and regular salt are not interchangeable. Curing salts contain active curing agents and must be used only for curing applications. Using curing salt as table salt would be unsafe.
How much curing salt should I use?
Always follow:
Manufacturer instructions
Your specific recipe
Applicable regulatory limits
Never guess or estimate. Precision is essential for both food safety and compliance.
Can I use both nitrite and nitrate together?
Yes — this is common in dry-cured sausages like salami.
Using both provides:
Immediate protection during early fermentation (nitrite)
Long-term protection during extended drying (nitrate)
This combination is especially useful for products cured over several weeks or months.
Is curing salt legal in the UK?
Yes.
Both E250 (sodium nitrite) and E252 (potassium nitrate) are approved food additives in the UK and EU when used within regulated limits and declared correctly on labels. Their use is product-specific and tightly controlled.
Do I need to declare curing salts on my label?
Yes.
You must list curing agents by name or E-number (e.g. sodium nitrite (E250) or potassium nitrate (E252)) in the ingredient declaration, in line with UK food labelling regulations.
Is nitrate “old-fashioned” or unsafe?
No — when used correctly.
Nitrate is still widely used in traditional dry curing, especially for long-aged products. It simply works differently than nitrite and requires proper fermentation conditions to be effective and safe.
Should beginners cure meat?
Yes — but start simply.
Beginners should:
Start with short cures
Use nitrite rather than nitrate
Use starter cultures
Keep detailed batch records
Avoid improvising salt levels
As experience grows, longer cures and more traditional methods become easier to manage.
How important are temperature and humidity?
Critical.
Curing relies on:
Correct fermentation temperatures
Controlled drying temperatures
Stable humidity levels
Incorrect conditions can lead to spoilage, texture defects, or safety risks, regardless of ingredient quality.
Can curing salt replace good hygiene?
No.
Curing salts support food safety, but they do not replace:
Proper temperature control
Clean equipment
Correct fermentation and drying
Good manufacturing practices
They work best as part of a controlled, hygienic production process.
How should curing salts be stored?
Clearly labelled
Stored separately from regular salt
Kept dry and sealed
Access limited to trained staff
Good storage practices are part of food safety compliance.
Why should I use pre-mixed curing salts?
Pre-mixed curing salts:
Reduce dosing errors
Improve batch-to-batch consistency
Support regulatory compliance
Are safer than handling pure curing agents
Sanita Spices supplies professionally formulated curing salts, along with spices, starter cultures, and functional blends, to help producers cure meat safely and consistently.
I’m not sure where to start — what should I do?
If in doubt:
Short, cooked, or fast-cured products → E250 (nitrite)
Long, slow dry curing → E252 (nitrate)
Extended dry-cured sausages → E250 + E252
Speaking with an experienced ingredient supplier can help avoid costly mistakes.
