Is INS 334 vegetarian?

INS 334 is from plants, so it does not by itself make a food non-vegetarian. The green or brown mark on the pack is still the declaration to go by, because it covers every other ingredient too.

Counted from the 58 packs in Zabel's catalogue that list INS 334, 46 of which have a food category so far. Counted 4 Nov 2026.
