One of my customers gave me some of this today...said it's a wonder product to use - many applications. Guess it was created back in 1958 in Croatia and Poland and now sold in 40 countries worldwide.
According to Wiki here's the ingredients:
salt max. 56%
dehydrated vegetables 15.5% (carrot, parsnip, onions, celery, parsley leaves)
flavour enhancers (MSG max. 15%, disodium inosinate)
sugar
spices
cornstarch
riboflavin (for yellow coloring)
Seems like basically a sodium-based seasoning.
