I know Maggi has a few different variations depending on what region of the world you're in but from what I can find, none of them contain any sort of fish or meat products.

Ingredients: Water, salt, wheat gluten, wheat, and less than 2% of wheat bran, sugar, acetic acid, artificial flavor, disodium inosinate, disodium guanylate, dextrose, caramel color.
I use self-raising flour instead of plain flour! It work in most recopies except choux pastry
Add a few drops of yellow food colouring to a batter to give it a creamy colour.
I just found out about Maggi Seasoning after 40 years of cooking. Its like a soy sauce you can add to western dishes.
I keep "French onion soup" mix in the fridge & add as a seasoning if a dish is bland
I now make gravy with pan juices + flour + stock cube + 2 teaspoons butter + some dried herbs + tablespoon of of wine, heat in microwave til boiling, blend with a stick blender & pass through a medium sieve. It makes a nice complex smooth gravy.
Try Maggi. I used it once when I was out of Worcestershire, and it was passable.
Maggi's looks like liquid MSG and salt. Is it this? Thanks btw.

Just wondering, do you have a link for information about vegan heme? My understanding is that heme comes from animal sources, and non-heme doesn't (I mean, until we get synthetic-media grown lab-grown meat). I'd be interested to read more about it, though.
As far as savory goes I love Liquid Smoke and Maggi Sauce to flavor my foods.
