Stability and Storage Conditions
Tagatose is stable under pH conditions typically encountered in foods (pH > 3). It is a reducing sugar and undergoes the Maillard reaction. Tagatose is stable under typical storage conditions. It caramelizes at elevated temperature.
Source and Preparation
Tagatose is obtained from D-galactose by isomerization under alkaline conditions in the presence of calcium.
Applications
Tagatose is used as a sweetening agent in beverages, foods, and pharmaceutical applications. A 10% solution of tagatose is about 92% as sweet as a 10% sucrose solution.It is a low-calorie sugar with approximately 38% of the calories of sucrose per gram. It occurs naturally in low levels in milk products.Like other sugars (fructose, glucose, sucrose), it is also used as a bulk sweetener, humectant, texturizer, and stabilizer, and may be used in dietetic foods with a low glycemic index.
Safety
Tagatose is safe for use in food and beverages. It has been used in pharmaceutical products.
Incompatibilities
A Maillard-type condensation reaction is likely to occur between tagatose and compounds with a primary amine group to form brown or yellow-brown colored Amidori compounds. Reducing sugars will also interact with secondary amines to form an imine, but without any accompanying yellow-brown discoloration.
