E211 is not a Product unless being sold by a chemical company to other large coompanies; but there are Products that may contain E211! It is a complete lie to say that a substance which occurs naturally in certain fruits contains pork fat! Unless of course the fruit were grown on pork fat.
Sodium benzoate (E211) has the chemical formula NaC6H5CO2. It is the sodium salt of benzoic acid and exists in this form when dissolved in water. It can be produced by reacting sodium hydroxide with benzoic acid. Sodium benzoate is produced by the neutralization of benzoic acid with sodium hydroxide.
Benzoic acid is detectable at low levels in cranberries, prunes, greengage plums, cinnamon, ripe cloves, and apples.[wikipidia] Though benzoic acid is a more effective preservative, sodium benzoate is more commonly used as a food additive because benzoic acid does not dissolve well in water.
