Switching curing ingredients starts with understanding their strength. Different products require different amounts to deliver approximately the same ingoing nitrite.
For recipes that support a nitrite-only curing system, the practical conversion covered here is:
Replace Cure #1 or Cure #2 used at 0.25% with VegCure 30k used at 0.52%.
This matches approximately the same initial nitrite addition. When replacing Cure #2, it does not replace that product’s nitrate component.
There are two separate numbers to understand:
Usage percentage: How much curing product you add compared with the starting meat weight.
Ingoing nitrite: How much nitrite that curing product contributes, expressed in parts per million, or ppm.
For example, adding VegCure 30k at 0.52% means adding 5.2 grams of powder per kilogram of meat. Its labeled strength of 30,000 ppm delivers 156 ppm ingoing nitrite at that rate. The 156 ppm refers to the nitrite supplied by the powder—not the amount of celery powder itself.
For sausage, use the combined starting weight of the meat and fat. These percentages are not based on the finished weight after drying or cooking.
Using the product strengths specified here:
| Curing product | Nitrite strength | Sodium nitrate content | Usage rate | Product per 1 kg meat | Calculated ingoing nitrite |
|---|---|---|---|---|---|
| Cure #1 | 6.25% sodium nitrite | None | 0.25% | 2.5 g | 156.25 ppm |
| Cure #2 | 6.2% sodium nitrite | 6.4% | 0.25% | 2.5 g | 155 ppm |
| VegCure 30k | Standardized to 30,000 ppm nitrite | None, for the product described here | 0.52% | 5.2 g | 156 ppm |
These are approximately equivalent initial nitrite additions, rather than three mathematically identical amounts.
Cure #2 also supplies 160 ppm ingoing sodium nitrate at its 0.25% usage rate. That nitrate is separate from its 155 ppm nitrite contribution.
Always check the package: Cure #2 formulations and vegetable curing powders can differ between suppliers. These calculations apply to the strengths shown above and assume the nitrite specifications use a comparable reporting basis.
When a suitable recipe calls for either Cure #1 or Cure #2 at 0.25%, calculate VegCure 30k directly from your meat weight:
Meat weight in grams × 0.0052 = grams of VegCure 30k
For example, a batch containing 5 kilograms of meat and fat weighs 5,000 grams.
The original curing-salt amount is:
5,000 × 0.0025 = 12.5 grams of Cure #1 or Cure #2
The replacement amount is:
5,000 × 0.0052 = 26 grams of VegCure 30k
Remove the original curing ingredient and use the replacement amount. Do not add both full doses.
If your recipe already lists the curing salt in grams, the shortcut for these stated usage rates is:
Original Cure #1 or Cure #2 weight × 2.08 = VegCure 30k weight
For example, 10 grams × 2.08 = 20.8 grams of VegCure 30k.
This shortcut converts the specified 0.25% rate to 0.52%; it does not make the three exact nitrite values identical.
| Starting meat and fat weight | Cure #1 or Cure #2 at 0.25% | VegCure 30k at 0.52% |
|---|---|---|
| 1 kg | 2.5 g | 5.2 g |
| 2 kg | 5 g | 10.4 g |
| 5 kg | 12.5 g | 26 g |
| 10 kg | 25 g | 52 g |
| 20 kg | 50 g | 104 g |
Choose the appropriate curing product for the recipe. The columns are alternatives, not ingredients to combine.
Nitrite supplies the active curing chemistry. Nitrate can serve as a reserve that certain bacteria convert into additional nitrite during processing.
Nitrate is not a universal requirement for dry curing. FSIS explicitly states that nitrite may be used alone or with nitrate in fermented products. Its guidance for salt-curing also recommends nitrite over nitrate because nitrate conversion depends on bacteria and processing conditions.
That means a properly developed dry-curing process can use a nitrite-only ingredient such as VegCure 30k.
However, optional does not mean removable from every established recipe without review. Replacing Cure #2 removes its nitrate reserve. A home producer should use a tested recipe that supports nitrite-only curing, or obtain a reviewed adaptation. Matching the initial ppm alone does not establish that the revised process is safe.
Likewise, Cure #1 and Cure #2 are not automatically interchangeable merely because both are used at 0.25%.
Curing blends also contribute ordinary salt. Changing products can therefore change your recipe’s total salt level.
For example, if the remainder of the blend is salt:
2.5 grams of Cure #1 contributes approximately 2.34 grams of salt.
2.5 grams of the specified Cure #2 contributes approximately 2.19 grams of salt.
VegCure 30k also contains sea salt, but its ingredient list alone does not establish the salt percentage. Use the supplier’s specification to calculate its contribution.
The adjustment is:
New separately added salt = original separately added salt + salt from the old cure − salt from the replacement cure
Do not subtract the entire increase in curing-powder weight from your salt. Some of that powder is cultured celery and other components.
Weigh in grams. Use a scale accurate enough for the quantity; teaspoons are unsuitable for comparing powders with different densities.
Use the specified product. Ordinary celery powder, celery salt, and other cultured celery products do not necessarily have VegCure 30k’s standardized strength.
Keep the full curing process in view. Salt, curing time, temperature, fermentation where applicable, and drying controls remain essential. Matching nitrite does not replace those controls.
Treat brines separately. The 0.52% rate here is based on meat weight. It is not a universal percentage of brine water.
Do not apply this chart automatically to bacon. Bacon has separate curing requirements, including a prohibition on added nitrate.
For professional processors: Confirm the supplier’s nitrite assay basis and specifications, applicable ingredient limits, labeling, and support for the revised process. FSIS expects changes from the curing ingredients and amounts used in scientific support to be justified.
