They're only 42% meat... What the heck the other 58% is, I don't want to know...
Edit: Oh, I found out -
E450 - You wouldn't expect sausages to contain added water but these low-meat sausages are practically dripping with it. The water is held in place by E450, a chemical which solidifies the mixture.
E412 - an emulsifier which helps to hold fat and water together (the meat in these sausages is almost half fat).
E300 and E307 - antioxidant vitamins which stop the fat content turning rancid. This givesthe product a long shelf life before it becomes unpalatable.
E223 - a sulphite preservative which keeps the sausages safe to eat and prolongs their shelf life. Some people find that sulphites provoke shortness of breath and asthma.
E128 - to disguise the low meat content these sausages have been coloured with a synthetic chemical Azo Dye called Red 2G.
Enjoy!
