DL-2-OXOTETRAHYDROFURAN-4,5-DICARBOXYLIC ACID - Introduction
DL-Isocitric acid lactone(DL-Isocitric acid lactone) is an organic compound. It is a white crystalline solid, sparingly soluble in water and soluble in organic solvents such as ethanol and acetate.
DL-Isocitric acid lactone is widely used in the food industry as a sour agent and acidulant. It can enhance the taste and flavor of food, and is used to make fruit juice, beverage, candy, jelly, bread and other food.
The preparation of DL-Isocitric acid lactone is usually carried out by citric acid hydrolysis reaction. First, citric acid is hydrolyzed by heating under acidic conditions to produce isocitric acid. Then, isocitric acid is converted to DL-Isocitric acid lactone by lactonization reaction through acid catalysis.
Regarding safety information, DL-Isocitric acid lactone is a food additive and is generally considered safe. In the process of food processing, it should be used according to the amount of use to ensure safety. However, for people with allergies, excessive intake of DL-Isocitric acid lactone may cause adverse reactions such as digestive tract discomfort, so it is necessary to pay attention to appropriate use.
