Sodium citrate: Sometimes known as “sour salt”, this sodium salt of citric acid stabilizes emulsified fat and provides a salty, sour taste that you often find in club soda.
Salt: Also known as sodium chloride, it’s added for taste as well as preservation — but it’s worth noting that one gram of salt per kilogram of body weight will kill a human. High salt intake can give you muscle cramps and dizziness, as well as neurological issues, stomach cancer, renal disease, strokes and high blood pressure.
Colour: Food colouring can be derived from seeds (annatto E160b red-orange), algae (chlorophyll E140 green), vegetables (Betanin), spices (carotenoids E160a) and even insects (Cochineal E120). One of the colours in the A&W shake is tartrazine (FD&C Yellow #5), which is a coal tar derivative that the U.K. Food Standards Agency says increases hyperactive behaviour in children and inflames the stomach lining of rats. Norway, Austria and Germany have tried to have it banned in Europe.
Calcium sulphate: An industrial chemical coagulant that comes from gypsum, this tasty white rock can be found in Plaster of Paris, fat spreads, beer and mustards, among hundreds of other things.
Quillaia: Used in vaccines for foot and mouth disease, this substance is the milled inner bark and branches of the soapbark tree and serves to keep food products moist by pulling moisture in from the air. It’s also used in plastics, cosmetics, hair conditioner and as a foaming agent in soft drinks.
Caramel: Made by, essentially, burning the water out of sugar, industrial caramel comes in many forms, such as a dark bitter liquid, or in candy form when boiled into cream, butter and vanilla flavouring.
Sodium benzoate: A preservative usually found in salad dressings, soft drinks and medicines. When you hear fireworks make a loud whistling sound, that’s sodium benzoate burning.
Potassium sorbate: Known as “wine stabilizer”, this salt comes from berries and inhibits mould and yeast.
Water: When A&W adds their root beer to the shake, this makes up the majority of it. But at least it’s good for you! If you prefer the diet root beer option, include aspartame, malic acid and dimethylpolysiloxane (a silicone used in contact lenses, shampoo and caulking). |
