Monosodium Fumarate: MONOFUMAR™ Monosodium fumarate
- Main Applications
Acidulant (jam, cyder, jelly, pickles, etc.)
- Applications
Basic Information
MONOFUMAR™ (Monosodium fumarate) is widely used as an acidulant mainly for juice, baking powder for bread and cakes, seasoning etc. It is a food additive that sufficiently covers the weak point of fumaric acid, which doesn’t easily dissolve in water.

Features and Properties
Maintains Fresh Flavor
The freshness of the fruit juice contained inside fruit is preserved by shutting out the open air from the liquid cavity and maintaining a suitable oxidation-reduction potential. However, the cell membranes are destroyed during squeezing, concentration, storage and other processes, and oxidation occurs with exposure to open air. This causes the natural flavor to rapidly lose its freshness. When MONOFUMAR™ is added in this state of lost freshness, there is an adequate reduction action as a result of a double bond with MONOFUMAR™. The effect is to preserve the oxidation-reduction potential required for fresh juice and maintain the fresh flavor.
Natural Acidity of Natural Fruit Juice from Buffer Effect
When MONOFUMAR™ is added in this state of lost freshness, there is an adequate reduction action as a result of a double bond with MONOFUMAR™. The effect is to preserve the oxidation-reduction potential required for fresh juice and maintain the fresh flavor. By adding MONOFUMAR™ during the manufacturing of fruit juice, as a method of adding an adequate amount of organic acids, it is easy to preserve the natural and mild acidic taste of natural fruit juice in the end product.
Good Water Solubility Compared to Fumaric Acid
This table shows a comparison of solubility in 100 cc water (g).
| Temperature | 25℃ | 40℃ | 60℃ | 100℃ |
|---|---|---|---|---|
| Fumaric Acid | 0.63 | 1.07 | 2.40 | 5.67 |
| MONOFUMAR™ | 6.86 | 10.74 | 18.15 | 30.20 |
Ordinary fumaric acid does not easily dissolve in water. In comparison, MONOFUMAR™ dissolves 10 times better, making it much more widely used in beverages.
Excellent Acidic Taste When Used with Citric Acid
