1. Fumaric Acid used as a seasoning, because E297 is the organic acid sourest taste. Fumaric Acid three parts are as sour as the five parts of citric acid.
2. Fumaric Acid but also as an antioxidant, mordant (a substance that helps the dye adhere to fabric), and as a buffer (to help maintain a particular acidity or alkalinity).
3. Fumaric Acid is used to lower the pH (acid to make more things, which taste more sour). This helps to a certain degree of anti-microbial agents, such as better work. Fumaric Acid itself to kill bacteria.
4. Fumaric Acid break the bread dough the elastic protein gluten of the sulfur-sulfur bond. This makes the dough more machinable. Fumaric Acid is in the use of rye bread and yeast, making them more acid.
5. Fumaric Acid combined with leavening agent (carbon dioxide gas produced carbin to make bread rise) to create slow. Because Fumaric Acid is only dissolved in warm water, leavening action postponed to start baking bread.
6. Fumaric Acid also used to produce unsaturated polyester resins, fumaric acid fumaric acid formula HO2CCH = CHCO2H compounds. This white crystalline compound of two isomers of the unsaturated dicarboxylic acid, maleic acid, the other one, which carboxylic acid groups of the CIS [= (Z)]. Fumaric Acid with fruit flavor. Added to food, Fumaric Acid is an acidity regulator, said via e-mail number Fumaric Acid.

Erythorbic Acid is vitamin C a stereoisomer, and thus the chemical nature of vitamin C similar. Erythorbic Acid white to light yellow or crystal powder, odorless, acid taste, melting point 166-172 ℃, and decomposition, Erythorbic Acid gradually darken when exposed to light. Dry state, Erythorbic Acid fairly stable in the air, and in solution when exposed to air and rapidly degenerate, E315 almost no role in the physiological activity of ascorbic acid, Erythorbic Acid antioxidant properties than ascorbic acid, but the Erythorbic Acid poor heat resistance, reduced intensity, decomposition of heavy metal ions can promote Erythorbic Acid, Erythorbic Acid soluble in water at room temperature solubility of 40g/100ml, soluble in ethanol, 5g/100ml, insoluble in glycerin, insoluble in benzene, 1% aqueous solution of the PH value of 2.8. Antioxidant sodium erythorbate, far more than the antioxidant capacity of vitamin C, no vitamin C to strengthen the role, but the Erythorbic Acid will not hinder the bodys absorption and utilization of ascorbic acid. Human intake of E315, the body can be transformed into vitamin C. U.S. Food and Drug Administration (1980) Erythorbic Acid is generally recognized as safe substances.
