Hello! Let's start the cooking section... for freaks. Or not so freaks, but we cannot always write on Spanish omelette - can we?
To begin with, I will review an ingredients' list... that we usually don't buy. But my wife is quite worried about them, because of our daughter's feeding: Food additives.
In Europe, those are indicated with an "E" letter and three numbers (and, sometimes, small cap letters) in prepared or coocked products ingredients' list.
Basically, there are six additive families:
1 - Colours
2 - Preservatives
3 - Antioxidants
4 - Sweeteners
5 - Emulsifiers, stabilisers, thickeners and gelling agents
6 - Other
For example, first one in the list is E100, Curcumin, a yellow colour. Or E150a, which is natural caramel (it should be produced out of burnt sugar...). If you see a label or product claiming no colour or preservative, it should not list any E1xx or E2xx. But it could contain antioxidants, such as E300 - citric acid, which could mean lemon juice...
Interestingly, sweeteners' list was ammended with numbers starting with nine, so that E951 corresponds to Aspartame, E954 to Sacarine. E967 is Xilitol, nowadays very common in chewing gum and candy... Dangerous - it's your choice...
Anyway, the official listing of additives can be downloaded from http://www.eufic.org/upl/1/default/doc/e-numbers_eufic(2).pdf
