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

The sauce is made from concentrated extracts, starches and added sugars, which require multiple industrial steps, placing it in the ultra‑processed NOVA 4 category; its only listed additives are caramel colour (E150) and xanthan gum (E415) used for colour and thickening.

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

With 23 g of sugars and 11 g of salt per 100 g, the sauce can raise blood glucose levels and increase sodium intake, making it unsuitable as a regular ingredient for people managing diabetes or high blood pressure; it should be used sparingly or omitted.

Is the oyster extract in this sauce a concern for people with shellfish allergies?

Yes, the sauce contains oyster and mussel extracts, which are mollusc proteins; individuals with shellfish allergies should avoid it as it can trigger allergic reactions.
