Isomalt, a popular sugar substitute, has been gaining traction in the food and pharmaceutical industries due to its unique properties and benefits. But have you ever wondered how this versatile sweetener is made? In this article, we will delve into the world of isomalt production, exploring the raw materials, manufacturing process, and applications of this fascinating substance.
What is Isomalt?
Before we dive into the manufacturing process, let’s take a brief look at what isomalt is and its characteristics. Isomalt is a disaccharide sugar substitute derived from sucrose. It is composed of glucose and mannitol molecules, which are bonded together through a hydrogenation process. This unique structure gives isomalt its distinct properties, including:
- Low glycemic index
- Low calorie count
- High sweetness intensity
- Resistance to caramelization and browning
- Stability in high-temperature and high-humidity environments
These characteristics make isomalt an ideal sweetener for various applications, including food, pharmaceuticals, and cosmetics.
Raw Materials and Manufacturing Process
The production of isomalt involves a multi-step process that requires specific raw materials and equipment. Here’s an overview of the manufacturing process:
Raw Materials
- Sucrose (table sugar)
- Hydrogen gas
- Nickel catalyst
- Water
- Activated carbon
Step 1: Hydrogenation
The first step in isomalt production is the hydrogenation of sucrose. This process involves the reaction of sucrose with hydrogen gas in the presence of a nickel catalyst. The reaction takes place at high temperatures (around 100°C) and pressures (around 50 bar). The resulting product is a mixture of glucose and mannitol molecules.
Step 2: Crystallization
The glucose and mannitol mixture is then cooled and crystallized to form a solid mass. This process involves the gradual cooling of the mixture, allowing the crystals to form and grow.
Step 3: Centrifugation and Washing
The crystallized mass is then centrifuged to remove excess water and impurities. The resulting crystals are washed with water to remove any remaining impurities.
Step 4: Drying and Milling
The washed crystals are then dried in a rotating drum or fluidized bed dryer to remove any remaining moisture. The dried crystals are then milled into a fine powder, which is the final form of isomalt.
Applications of Isomalt
Isomalt has a wide range of applications in various industries, including:
- Food and beverages: Isomalt is used as a sugar substitute in foods such as baked goods, candies, and ice cream. It is also used as a sweetener in beverages such as energy drinks and sports drinks.
- Pharmaceuticals: Isomalt is used as an excipient in pharmaceutical applications, such as tablets, capsules, and syrups.
- Cosmetics: Isomalt is used in cosmetics and personal care products, such as toothpaste, mouthwash, and skincare products.
Benefits of Isomalt
Isomalt has several benefits that make it an attractive alternative to sugar and other sweeteners. Some of the benefits of isomalt include:
- Low calorie count: Isomalt has a low calorie count, making it an ideal sweetener for weight management and calorie-restricted diets.
- Low glycemic index: Isomalt has a low glycemic index, which means it does not raise blood sugar levels. This makes it an ideal sweetener for people with diabetes or those who are trying to manage their blood sugar levels.
- High sweetness intensity: Isomalt is a highly sweet substance, which means it can be used in small quantities to achieve the desired level of sweetness.
- Stability: Isomalt is stable in high-temperature and high-humidity environments, making it an ideal sweetener for applications where stability is critical.
Conclusion

Its unique properties and benefits make it an attractive alternative to sugar and other sweeteners. The manufacturing process of isomalt involves a multi-step process that requires specific raw materials and equipment. Understanding the manufacturing process and benefits of isomalt can help you make informed decisions about its use in your products or applications.
What is Isomalt and where is it commonly used?
Isomalt is a low-calorie sugar substitute commonly used in the food industry, particularly in the production of sugar-free candies, chocolates, and baked goods. It is also used in the pharmaceutical industry as an excipient in tablets and capsules. Isomalt is a disaccharide composed of glucose and mannitol, which are derived from sucrose.
Isomalt has several benefits that make it a popular choice in the food and pharmaceutical industries. It has a low glycemic index, which means it does not raise blood sugar levels, making it suitable for people with diabetes. Additionally, isomalt is non-cariogenic, meaning it does not contribute to tooth decay. Its low calorie count and sugar-like taste also make it an attractive alternative to sugar in many applications.
What is the manufacturing process of Isomalt?
The manufacturing process of isomalt involves several steps, starting with the production of sucrose, which is derived from sugarcane or sugar beets. The sucrose is then converted into a syrup, which is mixed with a small amount of acid to break down the sucrose molecules into glucose and fructose. The mixture is then heated and concentrated to produce a crystalline substance.
The crystalline substance is then further processed to produce isomalt. This involves a series of steps, including crystallization, centrifugation, and drying. The resulting isomalt is a white, crystalline powder with a sugar-like taste and texture. The entire manufacturing process is carefully controlled to ensure the production of high-quality isomalt that meets the required standards for use in the food and pharmaceutical industries.
What are the different types of Isomalt available?
There are several types of isomalt available, each with its own unique characteristics and applications. The most common types of isomalt are isomalt DC, isomalt GS, and isomalt ST. Isomalt DC is a crystalline powder with a high purity level, making it suitable for use in pharmaceutical applications. Isomalt GS is a granulated form of isomalt, which is commonly used in the food industry. Isomalt ST is a syrup form of isomalt, which is used in applications where a liquid form is required.
The different types of isomalt are produced using different manufacturing processes, which affect their physical and chemical properties. For example, isomalt DC is produced using a crystallization process, while isomalt GS is produced using a granulation process. The choice of isomalt type depends on the specific application and the required characteristics of the final product.
What are the benefits of using Isomalt in food products?
Isomalt has several benefits when used in food products, including its low calorie count, non-cariogenic properties, and sugar-like taste.
