# Crystalline Maltitol: Properties and Applications

## Introduction to Crystalline Maltitol

Crystalline maltitol is a sugar alcohol commonly used as a sugar substitute in various food and pharmaceutical products. With its sweet taste and low glycemic index, it has gained popularity among manufacturers and consumers alike. This article explores the properties and applications of this versatile ingredient.

## Chemical and Physical Properties

Maltitol crystallizes as a white, odorless powder with several distinctive characteristics:

– Molecular formula: C12H24O11
– Sweetness: Approximately 90% as sweet as sucrose
– Caloric value: 2.1 calories per gram (compared to 4 calories for sugar)
– Solubility: Highly soluble in water
– Melting point: 145-150°C
– Hygroscopic nature: Absorbs moisture from the air

## Health Benefits

Crystalline maltitol offers several advantages over regular sugar:

Dental Health

Unlike sucrose, maltitol doesn’t promote tooth decay as it’s non-cariogenic. Many sugar-free chewing gums and candies use maltitol for this reason.

Blood Sugar Management

With a glycemic index of 35 (compared to 65 for sucrose), maltitol causes a slower rise in blood glucose levels, making it suitable for diabetics when consumed in moderation.

Lower Caloric Content

The reduced calorie count makes maltitol attractive for weight management products.

## Industrial Applications

### Food Industry

Maltitol finds extensive use in various food products:

– Sugar-free chocolates and confectionery
– Baked goods
– Ice creams and frozen desserts
– Chewing gums
– Diabetic-friendly products

### Pharmaceutical Applications

In the pharmaceutical sector, maltitol serves as:

– A sweetener in syrups and chewable tablets
– A bulking agent in powder formulations
– A coating material for pills

## 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 to form maltitol
4. Purification and crystallization
5. Drying and packaging

## Safety and Regulatory Status

Maltitol is generally recognized as safe (GRAS) by the FDA and approved for use in many countries worldwide. However, excessive consumption may cause gastrointestinal discomfort due to its incomplete absorption in the small intestine.

## Future Prospects

With increasing demand for sugar alternatives, the market for crystalline maltitol is expected to grow significantly. Ongoing research focuses on improving its functional properties and developing new applications in the food and pharmaceutical industries.

## Conclusion

Crystalline maltitol represents an excellent sugar substitute with numerous benefits and applications. Its favorable properties make it a valuable ingredient for manufacturers seeking to create healthier products without compromising on taste or quality.
