Why is Knorr Sauce Hollandaise with Lemon classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The sauce is made from many industrially refined ingredients such as modified starch, skimmed milk powder, fish powder, flavorings and emulsifiers, which place it in NOVA group 4; it lists three additives: a generic E14xx additive, citric acid (E330) as an acidifier, and xanthan gum (E415) as a thickener.

How does the sugar and salt content in this sauce affect a diabetic or hypertensive diet?

With 1.6 g of sugar and 1 g of salt per 100 ml, the sauce is low‑sugar but contains a moderate amount of sodium; it can fit into a diabetic meal plan if portion sizes are controlled, while hypertensive individuals should use it sparingly because the salt contributes to daily sodium intake.

Based on its ingredients, is this sauce suitable for vegan, keto, halal, or gluten‑free diets?

The sauce contains butter, milk powder, egg yolk powder and fish, so it is not vegan and may not meet strict halal standards that exclude dairy; its very low carbohydrate content makes it keto‑friendly, but it is not guaranteed gluten‑free because wheat traces are possible, and the presence of fish and dairy means it is unsuitable for vegans.

Product Insights

Knorr Sauce Hollandaise with Lemon is a pre‑packed, ready‑to‑use Hollandaise sauce marketed under the fat and sauces family (PNNS groups: Fat and sauces, Dressings and sauces). It carries a Nutri‑Score of D and is classified in NOVA group 4, indicating an ultra‑processed product; while it is low in sugar (1.6 g/100 ml) and salt (1 g/100 ml) and provides modest calories (~149 kcal/100 ml), it is high in saturated fat (8.6 g/100 ml) and contains three food additives (E14xx, E330 citric acid, E415 xanthan gum). The sauce also lists allergens such as eggs, milk and fish and may contain traces of wheat, celery, crustaceans, molluscs, mustard and soy, so consumers with these sensitivities should avoid it.
