Understanding the Additives in Your Salt
When you see a box of salt in the supermarket, it's easy to assume it contains only sodium chloride. However, many common table salts, including products from Morton, contain additives to serve specific purposes. The most common types of additives are anti-caking agents, iodine, and stabilizers like dextrose.
Anti-caking agents prevent the salt granules from sticking together, especially in humid conditions. Iodine is added for public health reasons to prevent iodine deficiency, which can cause thyroid issues. When iodine is added, a stabilizer like dextrose is also included to keep the iodine from oxidizing. Knowing what's in your salt allows you to make a more informed decision for your cooking and health.
Morton Salt Product Ingredients and Additives
Morton offers a variety of salts, and the presence of additives depends entirely on the specific product. Below is a breakdown of some of their most popular options.
Morton Iodized Table Salt
This is perhaps the most well-known product from the brand. Its ingredients are more complex than just salt. The label typically lists: salt, calcium silicate (an anti-caking agent), dextrose, and potassium iodide.
- Potassium Iodide: Provides the essential mineral iodine.
- Dextrose: A type of sugar that acts as a stabilizer to prevent the potassium iodide from oxidizing and losing its effectiveness.
- Calcium Silicate: A food-safe additive that absorbs moisture to prevent clumping.
Morton Plain Table Salt
This product is similar to the iodized version but without the added iodine. It does, however, contain an anti-caking agent to ensure it pours smoothly. Some variants may use different anti-caking agents like yellow prussiate of soda.
Morton Natural Sea Salt
According to the company, this product is 100% natural and contains no additives. As a result, it may be more prone to caking together in humid environments.
Morton Kosher Salt
Morton's Kosher salt is known for its larger, squared flake crystals. It is often treated with an anti-caking agent, such as sodium ferrocyanide. Unlike table salt, it does not contain added iodine.
Comparison Table: Morton Salt Additives by Type
| Feature | Morton Iodized Table Salt | Morton Natural Sea Salt | Morton Kosher Salt |
|---|---|---|---|
| Contains Additives? | Yes | No | Yes |
| Iodine Added? | Yes | No | No |
| Anti-caking Agent? | Yes (Calcium Silicate) | No | Yes (Sodium Ferrocyanide) |
| Grain Texture | Fine, uniform crystals | Fine, natural crystals | Coarse, flaky crystals |
| Caking Potential | Low | High (natural) | Low |
| Dietary Consideration | Source of Iodine | Additive-free | Additive-free (no iodine) |
Why Are Additives Used in Salt?
- Preventing Deficiency: The most historically significant reason for adding iodine to salt is to combat iodine deficiency, which can cause serious health problems like goiter.
- Convenience: Anti-caking agents ensure a product that pours freely, making it easier for consumers to use in shakers and industrial settings.
- Stability: Dextrose stabilizes the iodine in iodized salt, preventing it from degrading and losing its nutritional value over time.
Should You Choose a Salt with or Without Additives?
The decision to use a salt with or without additives depends on your dietary needs and cooking preferences.
-
Iodine Intake: If your diet lacks other iodine sources (like seafood, dairy, and fortified cereals), iodized salt is an effective way to meet your daily requirements. However, if you already get enough iodine, you might prefer a non-iodized option to avoid excess intake.
-
Health Concerns: The anti-caking agents used by Morton are generally recognized as safe (GRAS) by regulatory bodies like the FDA, but some individuals may prefer to avoid any added chemicals. In such cases, products like Morton Natural Sea Salt or other additive-free brands are a good choice.
-
Taste and Cooking: While salt is primarily sodium chloride, some people notice a subtle difference in taste between iodized and non-iodized salts. Kosher salt's larger crystal structure also means less sodium per teaspoon compared to finer table salt, which can influence how you season food.

Conclusion
In summary, it's incorrect to assume all Morton salt is additive-free. While products like Morton Natural Sea Salt contain no additives, the company's well-known iodized table salt includes an anti-caking agent, iodine, and a dextrose stabilizer. Other salts, like kosher varieties, typically include an anti-caking agent but no iodine. By reading product labels and understanding the function of common additives, you can easily choose the right Morton salt for your health and cooking needs.
