Key findings
- 1Commercial muffins add emulsifiers, preservatives, and dough conditioners to achieve multi-week shelf life; a homemade muffin goes stale in 2-3 days because it lacks these industrial additives
- 2Bakery-chain muffins are often far larger than a homemade muffin, and the emulsifiers help an oversized portion hold together
- 3Baking muffins at home takes about 30 minutes for a batch of 12, with a short list of recognizable ingredients
Why is Muffins ultra-processed on average?
The gap between a homemade muffin and a commercial one is significant. A home recipe uses flour, sugar, butter or oil, eggs, milk, baking powder, salt, and perhaps vanilla, about 8 ingredients. Commercial muffins (from grocery store bakeries and coffee chains) often replace butter with vegetable oil blends, add mono- and diglycerides (emulsifiers for moisture retention), sodium stearoyl lactylate (a dough conditioner), modified food starch (texture), polysorbate 60 (another emulsifier), and calcium propionate (mold inhibitor). These additives enable a muffin to sit in packaging for weeks instead of going stale in 2-3 days. In our analysis, muffin products average a Processing Score of 11.4, which is Level 4. The other commercial muffin issue is portion size: many bakery-chain muffins are far larger than a homemade one, and the emulsifiers help an oversized muffin hold its structure.

Frequently asked questions
Are store-bought muffins ultra-processed?
Most commercial muffins list emulsifiers, preservatives, and modified starches, and some add artificial flavors and colors. In our analysis, muffin products average a Processing Score of 11.4, which is Level 4. Homemade muffins from basic ingredients are far less processed.
Are bakery muffins healthier than packaged muffins?
Grocery store bakery-counter muffins are usually made from industrial mixes and contain similar additives to packaged varieties. True bakery muffins made fresh on-site with simple ingredients are less processed, but calorie counts can still be very high due to portion size.
How many calories are in a Costco muffin?
It varies by flavor, so check the store's nutrition information. Bakery-chain muffins are often far larger than a standard homemade muffin, and the emulsifiers and stabilizers in a commercial formulation help an oversized portion hold together.
