to optimize processes and products. The spectrum of isomalt applications is broad<br />

and listed below:<br />

• High-boiled candies<br />

• Pan-coated products<br />

• Chewing gum<br />

• Low-boiled candies<br />

• Compressed tablets/lozenges<br />

• Chocolate<br />

• Baked goods and baking mixes<br />

• Ice cream<br />

• Jams and preserves<br />

• Fillings, fondant<br />

• Marzipan, croquant, and nougat<br />

• Cereal extrudates<br />

• Pharmaceutical applications<br />

• Technical applications<br />

All these products can be made with isomalt-ST. The new isomalt types,<br />

however, are specifically designed to improve certain characteristics in finished<br />

products and/or to simplify production processes. The new isomalt types will be<br />

discussed together with their main applications.<br />

A. High-boiled Candies<br />

High-boiled candies made with isomalt can be stamped, filled, pulled, combed,<br />

or molded. Hard candies with a very good shelf-life will be obtained if the water<br />

content in the finished product is less than 2%. These candies are very stable<br />

against water absorption. Compared with candies based on sucrose/corn syrup,<br />

only minor changes in the production process (batch or continuous) are required.<br />

The minor changes are necessary because the following characteristics of isomalt<br />

differ from sucrose/corn syrup (9, 30–34):<br />

• Lower solubility<br />

• Higher boiling point<br />

• Lower viscosity of the melt<br />

• Higher specific heat capacity<br />

Recently, a new type, isomalt-HB, has been specially designed, for example,<br />

for the manufacture of hard candies. Like isomalt-ST, isomalt-HB is an odorless,<br />

white, crystalline powder. The storage conditions of both isomalt types are<br />

the same, namely at 20 10°C and 40–70% rh. They differ slightly in composition,<br />

for example, in content of mannitol and sorbitol.
