About taste can ever known argue, but about ingredients not. On the list of "Ingredients" I can not find monosodium glutamate. Also on the website of Vegemite is only of Potassium Chloride-called "flavor enhancer" is mentioned, but that is potassium chloride and approved in the EU without maximum limit. Otherwise you could get excited yet about the dye E150d, which is ammonium sulfite caramel and a brown dye, which is also used in soft drinks and other beverages. Sorry, but of monosodium I have found nothing here. And the delivery went smoothly, the goods were fresh and you can say what you like, the stuff is (in small portions) but simply delicious ...
