What Is Fumaric Acid?

Fumaric acid is used in a wide variety of foods often to add or intensify the sour flavor of a food In addition it is also helpful to increase the acidity levels of food which then helps to prevent mold growth and keep the food safe to eat for longer periods of time The presence of fumaric acid in a food always depends on the brand that creates that food but you might find the additive

why maleic acid is more acidic than fumaric acid

Maleic acid is more stronger acid as compared to the fumaric acid because in maleic acid after the loss of 1 proton cis anion is formed which is stabalised by intramolecular hydrogen bonding while in case of fumaric acid no such stabalisation of anion occur Structure of maleic acid is given below : Structure of fumaric acid is given below
