Most consumers recognize the iconic round blue package of Morton salt, but few know the specific ingredients beyond sodium chloride. The simple truth is that while some specialty salts from the brand contain no additives, the standard table salt you find on most shelves does. These additives serve specific purposes related to functionality, stability, and nutrition, making the salt a consistent and reliable kitchen staple.
The Additives in Morton Iodized Table Salt
Anti-Caking Agents
One of the most common issues with salt is that it can clump together in humid conditions due to its natural moisture-absorbing properties. To prevent this and ensure the salt pours freely from a shaker, manufacturers add anti-caking agents. For Morton's iodized table salt, the ingredient used is typically Calcium Silicate. In other variations or commercial products, alternatives like yellow prussiate of soda may be used. These agents are added in very small, food-safe quantities and are largely insoluble.
Iodine Supplementation
To address iodine deficiency in the population, Morton has been adding iodine to its table salt for decades. For its standard iodized salt, the brand uses Potassium Iodide. Iodine is a necessary nutrient for proper thyroid function, and adding it to a common food item proved to be an effective public health measure.
Iodine Stabilizer
Adding potassium iodide to salt presents a problem: iodide can oxidize and evaporate over time, reducing its nutritional benefit. To combat this, Morton adds a small amount of Dextrose, a sugar, to its iodized salt. Dextrose acts as a stabilizer, preventing the oxidation of the iodide and ensuring the salt retains its nutritional content throughout its shelf life.
Comparison of Common Morton Salt Products
| Product | Anti-Caking Agent | Iodine Added | Other Additives | Notes |
|---|---|---|---|---|
| Iodized Table Salt | Calcium Silicate | Yes (Potassium Iodide) | Dextrose (stabilizer) | All-purpose, free-flowing, enriched |
| Plain Table Salt | Calcium Silicate | No | None | All-purpose, free-flowing, not enriched |
| Kosher Salt (Coarse) | Yellow Prussiate of Soda | No | None | Rolling process creates large flakes, minimal processing |
| Natural Sea Salt | No | No (some varieties are) | None | Derived from evaporated seawater, naturally free of additives |
The Role of Additives in Your Salt
Here are the key takeaways regarding the additives in Morton salt:
- Free-Flowing Salt: Anti-caking agents are essential for preventing clumping, a common issue with salt, which ensures it can be easily poured from a shaker.
- Nutritional Fortification: The addition of potassium iodide helps prevent iodine deficiency disorders like goiter, a public health initiative that began in the 1920s.
- Stability and Consistency: Dextrose serves to stabilize the added iodine, ensuring the nutritional value remains consistent over time.
- Varies by Product: Not all Morton salts are the same. Their natural sea salt is additive-free, and plain table salt lacks iodine, so checking the label is important.
- Quantity is Trace: The concentration of these additives is extremely low, present in minute amounts necessary to perform their function without impacting the flavor or safety of the product.

Conclusion
In conclusion, the question "does Morton table salt have additives?" is best answered by specifying the product. Standard iodized Morton table salt does contain additives, including calcium silicate to prevent caking, potassium iodide for nutrition, and dextrose to stabilize the iodide. These additives are intentionally included for specific functional and health-related purposes. If you prefer salt without these additions, Morton offers other products like their natural sea salt, which contains no additives. The safety and benefits of these trace-level additives have been well-established, but personal preference for pure, unadulterated salt leads many to choose alternatives like kosher or plain salt. Ultimately, reading the product label is the best way to know exactly what is in your shaker.
