Firming agent

Firming agents are food additives that are designed to ensure a higher or longer lasting strength, for example, the pulp of fruits, simultaneously therewith, but pretend freshness.

Are salts, typically lactates or phosphates, salts of calcium or aluminum sulfates.

They are mainly used in ( fresh ) fruits and vegetables. For example, can be sprayed with a solution of the salt with sliced ​​into columns sold fruit pulp. Are salts which react with an ingredient of the product, such as for example the pectin in the fruit.

The following additives are permitted for strengthening of food in the European Union:

  • Calcium (E 263)
  • Sodium lactate (E 325)
  • Potassium lactate (E 326)
  • Calcium lactate (E 327)

  • Potassium orthophosphate (E 340; potassium dihydrogen phosphate, dipotassium hydrogen phosphate and potassium phosphate);
  • Calcium phosphates ( E 341, calcium dihydrogen phosphate, calcium hydrogen phosphate and calcium phosphate);
  • Calcium tartrate (E 354)
  • Diphosphate (E 450),
  • Triphosphates (E 451; triphosphate and triphosphate ),
  • Polyphosphates ( E 452 ),
  • Potassium chloride (E 508)
  • Calcium chloride (E 509)
  • Magnesium chloride (E 511)
  • Sodium sulphate ( E 514, sodium sulfate and sodium bisulfate ),
  • Potassium sulfate ( E 515),
