Ultra-processed foods are industrially formulated products that are not typically found in home kitchens, often containing ingredients such as artificial additives, stabilizers, emulsifiers, and preservatives. Examples of ultra-processed foods include:

Not *homes*. *Kitchens* and normal people who don't always try to pot stir know what was meant.

[Jamestown1630]

That may be what they meant; but I think it’s poor writing.
