# Maltitol Crystals: Properties and Applications

Introduction to Maltitol Crystals

Maltitol crystals are a popular sugar substitute derived from maltose through hydrogenation. As a polyol (sugar alcohol), maltitol offers similar sweetness to sugar while providing fewer calories and a lower glycemic index. The crystalline form of maltitol is particularly valued in food manufacturing for its stability and ease of use.

Physical and Chemical Properties

Maltitol crystals exhibit several distinctive characteristics:

• Appearance: White, crystalline powder
• Sweetness: Approximately 90% as sweet as sucrose
• Solubility: Highly soluble in water (about 60% at 20°C)
• Melting point: 145-150°C
• Hygroscopicity: Lower than other polyols like sorbitol
• Caloric value: 2.1 kcal/g (compared to 4 kcal/g for sugar)

Advantages of Maltitol Crystals

Maltitol crystals offer several benefits that make them attractive for various applications:

• Reduced calorie content compared to sugar
• Lower impact on blood glucose levels
• Non-cariogenic (doesn’t promote tooth decay)
• Good thermal stability for cooking and baking
• Minimal aftertaste compared to some other sweeteners

Food Applications

Maltitol crystals find extensive use in the food industry:

Confectionery

Widely used in sugar-free chocolates, hard candies, and chewing gums due to its similar melting profile to sugar.

Baked Goods

Functions well in cookies, cakes, and pastries where bulk and texture are important.

Pharmaceuticals

Used as an excipient in chewable tablets and syrups to improve palatability.

Dairy Products

Added to ice creams and yogurts as a sugar replacement that doesn’t compromise texture.

Considerations and Limitations

While maltitol crystals offer many advantages, there are some considerations:

• May cause digestive discomfort if consumed in large quantities
• Not completely calorie-free
• Still affects blood sugar, though less than regular sugar
• More expensive than regular sugar

Conclusion

Maltitol crystals represent an excellent sugar alternative for many applications, particularly in products targeting reduced-calorie or diabetic-friendly markets. Their physical properties closely mimic sugar while offering significant metabolic advantages. As consumer demand for healthier sweeteners grows, maltitol crystals are likely to see continued growth in food and pharmaceutical applications.
