Threitol

Threitol

Threitol is a type of sugar alcohol that is commonly used in the food industry as a sweetener and humectant. It is a diastereomer of erythritol and is also known as D-threitol due to its D-configuration.

Chemical Structure and Properties

Threitol is a four-carbon sugar alcohol with the chemical formula C4H10O4. It is a white, crystalline solid at room temperature and is soluble in water. Threitol has two chiral centers, giving it four possible stereoisomers. However, only the D- and L- forms are naturally occurring.

Production and Uses

Threitol can be produced synthetically through the hydrogenation of threose, a four-carbon monosaccharide. It is used in the food industry as a sweetener and humectant due to its sweet taste and ability to retain moisture. It is also used in the pharmaceutical industry as an excipient in the formulation of certain drugs.

Health Effects

Like other sugar alcohols, threitol is not fully absorbed by the body and therefore does not raise blood sugar levels as much as regular sugar. This makes it a popular choice for diabetic foods and sugar-free products. However, excessive consumption of threitol can lead to digestive issues such as bloating and diarrhea.
