Is Salad Dressing Ultra Processed?
Yes — Ultra-Processed
Most bottled salad dressing is Level 3-4. Commercial dressings typically contain soybean oil, sugar or HFCS, xanthan gum, EDTA (calcium disodium), potassium sorbate, and "natural flavors." The majority of bottled dressings are significantly more processed than a simple vinaigrette.
Key Findings
- •The core processing challenge in bottled dressing is maintaining oil-water emulsion stability for months rather than minutes
- •EDTA chelates metal ions that catalyze rancidity, extending shelf life from weeks to over a year
- •Homemade vinaigrette (oil, vinegar, mustard, salt) is Level 1 — the widest processing gap of any condiment category
Why Is Salad Dressing Ultra-Processed?
The fundamental challenge in commercial salad dressing is emulsion stability. Oil and water (or vinegar) naturally separate — in a restaurant or home kitchen, you shake the bottle and use it immediately. Commercial dressings must remain emulsified for months on a shelf, which requires industrial emulsifiers (polysorbate 60, soy lecithin), stabilizers (xanthan gum, propylene glycol alginate), and preservatives (EDTA, potassium sorbate). EDTA is particularly notable: it is a chelating agent that binds metal ions which would otherwise catalyze oxidation and rancidity. This single additive extends shelf life from weeks to a year or more. The irony is that the simplest salad dressing — olive oil and vinegar — requires zero processing and no emulsification.

How to Read Salad Dressing Labels
- 1
Soybean oil as the first ingredient is ubiquitous in commercial dressings — it is the cheapest option, not the most flavorful
- 2
EDTA (calcium disodium EDTA) is a chelating agent that extends shelf life dramatically but signals industrial processing
- 3
Xanthan gum and propylene glycol alginate are stabilizers that prevent separation over months of shelf time
- 4
Olive oil-based dressings with vinegar and minimal additives are the least processed bottled option
Frequently Asked Questions
Is bottled salad dressing ultra-processed?
Most are Level 3-4. Standard brands contain 15-20 ingredients including industrial emulsifiers, EDTA, artificial flavors, and added sugars. The simplest option — oil and vinegar — requires zero processing.
What is the least processed salad dressing?
Plain olive oil and vinegar (Level 1). For bottled options, look for dressings listing olive oil first with minimal additives. Primal Kitchen and some Whole Foods 365 dressings have simpler formulations at Level 2-3.
Why does salad dressing have so many ingredients?
The main challenge is keeping oil and water from separating during months on store shelves. This requires emulsifiers (polysorbate 60), stabilizers (xanthan gum), and preservatives (EDTA, potassium sorbate) that a shake-before-use homemade dressing does not need.
Is Italian dressing ultra-processed?
Most commercial Italian dressing is Level 3-4. Despite its simple-sounding name, brands like Wish-Bone contain soybean oil, sugar, EDTA, xanthan gum, and calcium disodium. A homemade version with olive oil, vinegar, and dried herbs is Level 1.
