E575-GLUCONO DELTA LACTONE

E575 refers to glucono delta-lactone (GDL), which is a food additive used primarily as an acidulant, sequestrant, and leavening agent. It is a naturally occurring compound and is often used in the food industry for various purposes. 

• Chemical Structure: Glucono delta-lactone is a white, odorless crystalline powder with the chemical formula C6H10O6.
• Acidulant: GDL is a slow-acting acid that is gradually hydrolyzed into gluconic acid in the presence of water. This property makes it useful in adjusting the acidity of food products and in controlling the rate of pH reduction.
• Sequestrant: It functions as a sequestrant, which means it can bind or chelate metal ions. This property is valuable in preventing the discoloration or deterioration of certain foods caused by the presence of metal ions.
• Leavening Agent: GDL is also used as a leavening agent in certain food products. It contributes to the production of carbon dioxide, which helps in the leavening or rising of baked goods.
• Applications: Glucono delta-lactone is commonly used in the food industry in various products such as dairy, meat, beverages, and baked goods. It is often employed in the production of tofu to regulate the coagulation process.
• Slow Hydrolysis: GDL undergoes slow hydrolysis, converting into gluconic acid over time. This gradual acidification is advantageous in certain food processing applications where a controlled release of acid is desired.
• Natural Origin: GDL is derived from glucose and is considered a naturally occurring acidulant. It is often used in products marketed as natural or organic.
• Regulatory Approval: GDL is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. It is approved for use as a food additive in various regions worldwide.
