Why is Quiche Lorraine classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The product is made from multiple processed ingredients, including refined wheat flour, cured meats and dairy, and includes three food additives: sodium nitrite (E250) as a preservative, sodium erythorbate (E316) as an antioxidant, and citric acid (E330) as an acidifier, which place it in the ultra‑processed NOVA 4 category.

How does the salt content of this quiche affect a hypertensive or low‑sodium diet?

With 0.92 g of salt per 100 g, the quiche contributes a moderate amount of sodium; for someone on a low‑sodium or hypertension‑focused diet, it should be counted toward daily limits and balanced with lower‑salt foods throughout the day.

Is Quiche Lorraine suitable for consumers avoiding gluten, dairy, or eggs?

No. The quiche contains wheat flour (gluten), eggs, cream, emmental cheese and milk powder, making it unsuitable for gluten‑free, dairy‑free, or egg‑free diets.
