# Crystalline Maltitol: Properties and Applications
## Introduction to Crystalline Maltitol
Crystalline maltitol is a sugar alcohol commonly used as a sugar substitute in various food products. With its sweet taste and low glycemic index, it has become a popular choice for manufacturers looking to create reduced-sugar or sugar-free alternatives.
## Chemical and Physical Properties
Maltitol crystallizes in a white, odorless powder form with the following characteristics:
– Molecular formula: C12H24O11
Keyword: maltitolo cristallino
– Sweetness: Approximately 90% as sweet as sucrose
– Caloric value: 2.1 kcal/g (compared to 4 kcal/g for sugar)
– Solubility: Highly soluble in water
– Melting point: 145-150°C
– Hygroscopicity: Lower than other polyols
## Manufacturing Process
The production of crystalline maltitol involves several steps:
1. Extraction of starch from corn or wheat
2. Enzymatic hydrolysis to produce maltose syrup
3. Hydrogenation of maltose under high pressure
4. Crystallization and purification
5. Drying and packaging
## Applications in Food Industry
### Confectionery Products
Crystalline maltitol is widely used in sugar-free candies, chocolates, and chewing gums due to its:
– Similar texture to sucrose
– Good heat stability
– Non-cariogenic properties
### Baked Goods
In bakery applications, maltitol offers:
– Bulk similar to sugar
– Browning capability
– Moisture retention properties
### Pharmaceutical Applications
The pharmaceutical industry utilizes crystalline maltitol for:
