Yes — Mayonnaise is ultra-processed.
The mayonnaise is ultra-processed because it contains industrial ingredients and additives such as modified maize starch and flavouring (contains mustard), which are characteristic of NOVA ultra-processed foods. Other ingredients like rapeseed oil, egg yolk, vinegar, sugar, salt, and lemon juice are basic culinary ingredients and do not by themselves make the product ultra-processed.

The classification is based on the NOVA system used by researchers and dietitians worldwide.
