Fumaric acid is also an essential ingredient in plant life.Fumaric acid is the strongest organic food acid in titratable acidity and in sourness.umaric acid acts as an instant flavouring agent for rye and sourdough breads. Fumaric acid is simply added to the dough ingredients during the dry blending step. Flavour intensity is easily controlled by the amount of Fumaric acid added to the recipe.
