Is INS 575 vegetarian?
It depends on the maker. INS 575 can be made from plant or animal sources and the label does not say which, so the code tells you nothing either way. The green or brown mark on the pack is the declaration to go by.
Too few packs in our catalogue list INS 575 for a breakdown by food to mean anything yet. We print one once at least 20 categorised packs carry it.
What does the evidence say about INS 575?
We grade an additive by the evidence about it, not by whether it sounds like a chemical, and we make no claim about whether a pack complies with FSSAI rules.
No numerical limit and no identified concern at food levels.
Does Zabel mark INS 575 down?
No. On the evidence we hold it takes nothing off the score (method 1.0.0). Read the method.
