# 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 increasingly popular in the food industry, particularly in products marketed as “sugar-free” or “low-calorie.”

## Chemical and Physical Properties

Maltitol crystallizes in a white, odorless form with the following characteristics:

– Molecular formula: C12H24O11
– 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: Around 150°C
– Hygroscopicity: Lower than other polyols

## Production 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

## Advantages Over Other Sweeteners

Crystalline maltitol offers several benefits compared to other sugar substitutes:

– Better taste profile than many artificial sweeteners
– Minimal aftertaste
– Good heat stability for baking applications
– Does not promote tooth decay
– Suitable for diabetics (when consumed in moderation)

## Common Applications in Food Industry

This versatile sweetener finds use in numerous products:

### Confectionery

– Sugar-free chocolates
– Hard candies
– Chewing gums
– Gummies and jellies

### Baked Goods

– Cookies and biscuits
– Cakes and pastries
– Cereal bars

### Dairy Products

– Ice cream
– Yogurts
– Flavored milks

### Other Applications

– Pharmaceutical syrups
– Nutritional supplements
– Oral care products

## Health Considerations

While crystalline maltitol is generally recognized as safe, consumers should be aware of:

– Potential laxative effects when consumed in large quantities
– Lower glycemic response compared to sugar, but not completely carb-free
– May cause bloating or gas in sensitive individuals
– Not suitable for individuals with rare hereditary fructose intolerance

## Storage and Handling

Proper storage conditions for crystalline maltitol include:

– Keep in a cool, dry place
– Maintain in sealed containers
– Avoid exposure to high humidity
– Shelf life of approximately 2 years when stored properly

## Future Trends

The market for crystalline maltitol continues to grow due to:

– Increasing demand for reduced-sugar products
– Rising health consciousness among consumers
– Expansion of diabetic-friendly food options
– Technological advancements in production methods

As food manufacturers seek better sugar alternatives, crystalline maltitol remains a popular choice for its balanced properties and wide range of applications.
