Firstly, it can enhance the stability of food products, particularly in preventing spoilage caused by microorganisms that thrive in specific pH environments. Secondly, it affects the texture and appearance of food. Thirdly, a stable pH can help preserve color and nutritional value in certain food types. By acting as a buffering agent, DSS helps to extend shelf life and maintain the quality of food over time. Common applications include canned goods and beverages.
Potential Antioxidant Capabilities
While not the primary function, there is some research suggesting succinate itself might have potential antioxidant activity. Antioxidants are important for counteracting the damaging effects of free radicals, which can contribute to spoilage and deterioration. In food, this can help to maintain the freshness and extend the shelf life of products. Disodium succinate’s potential antioxidant properties might further contribute to its use in preserving the quality of food. The presence of antioxidants in food products helps to protect against oxidative damage, which leads to rancidity, discoloration, and a decline in nutritional value. This protection becomes important, especially for products containing fats and oils, which are prone to oxidation.
Other Applications
Although its primary application is in food, disodium succinate may find use in other fields. For example, it could be used in animal feed, contributing to the palatability and shelf life of those products, too. However, the food-grade version is solely designed for applications in food and is manufactured with the utmost care and quality controls.
