Maltotriose丨CAS 1109-28-0

Maltotriose丨CAS 1109-28-0 is a naturally occurring trisaccharide composed of three glucose units linked by α-1,4 glycosidic bonds. It is the second most abundant sugar in malting and brewing processes (after maltose) and plays a vital role in carbohydrate metabolism, fermentation, and nutritional science.

 

Applications

1. Brewing and Fermentation Industries

Maltotriose丨CAS 1109-28-0 is a significant fermentable sugar derived from enzymatic hydrolysis of starch in malting. It is the third most common sugar in wort (after glucose and maltose). In brewing:

Yeast strains (like Saccharomyces cerevisiae or Saccharomyces pastorianus) ferment maltotriose to produce ethanol and CO₂

Its utilization affects attenuation, alcohol yield, and flavor profile

Breweries often select or engineer yeast strains based on their ability to metabolize maltotriose efficiently

This sugar is essential for producing:

Beer

Distilled spirits

Alcoholic kombucha and fermented teas

2. Food Industry (Functional and Nutritional Ingredients)

Maltotriose is used as:

A mildly sweet carbohydrate in low-calorie or low-sugar formulations

A prebiotic or digestible oligosaccharide

A controlled-release energy source in sports nutrition and diabetic foods

It also serves as a building block in maltodextrins and glucose syrups, contributing to:

Improved texture and mouthfeel

Lower glycemic response compared to pure glucose

Gradual energy release for sustained activity

3. Prebiotics and Gut Health

Though digestible in the small intestine, some maltotriose may escape digestion and act as a prebiotic, selectively promoting the growth of beneficial gut bacteria like:

Bifidobacterium

Lactobacillus

This contributes to:

Better gut flora balance

Enhanced intestinal barrier function

Potential support for immune health

4. Pharmaceutical and Nutraceutical Formulations

Maltotriose is used in:

Controlled-release matrices due to its stability and solubility

Infant and clinical nutrition as a safe, mild carbohydrate source

Formulations for athletes or post-operative recovery diets

Its slow absorption profile helps avoid spikes in blood glucose, making it favorable in metabolic nutrition.

5. Biotechnology and Microbiology

In research and industrial microbiology, maltotriose is used as:

A carbon source in media for studying sugar metabolism

A substrate in enzymatic assays (e.g., testing α-amylase or glucoamylase activity)

A model trisaccharide in carbohydrate transport and fermentation studies

It helps evaluate yeast strain efficiency and optimize microbial performance.

6. Ingredient in Functional Beverages and Foods

Used in:

Sports drinks for sustained energy

Meal replacements

Protein shakes to enhance caloric content without sharp sweetness

Baked goods where it contributes to browning, texture, and moisture retention

 

Benefits

1. Sustained Energy Source

Compared to glucose or maltose, maltotriose:

Is digested more slowly

Releases glucose into the bloodstream gradually

Provides longer-lasting energy, reducing blood sugar spikes

Ideal for:

Athletes

Diabetics

Long-duration physical activity

2. Mild Sweetness and Low Glycemic Impact

With a sweetness level lower than sucrose, maltotriose:

Can reduce overall sweetness in formulations

Offers a lower glycemic index

Provides a balanced taste profile for health-conscious products

3. Prebiotic Potential

Some studies suggest maltotriose can support gut health by:

Feeding selective beneficial microbes

Enhancing short-chain fatty acid (SCFA) production in the colon

Contributing to microbiome diversity

4. Supports Efficient Fermentation

In brewing and fermentation:

Yeast's ability to consume maltotriose improves alcohol yield

Impacts flavor, mouthfeel, and final attenuation

Ensures complete sugar utilization and reduces residual sweetness

 

Conclusion

Maltotriose丨CAS 1109-28-0 is more than just a minor sugar-it's a functional, fermentable, and health-conscious carbohydrate. It supports key processes in brewing, enhances nutritional formulations, and offers prebiotic and metabolic benefits. Whether you're optimizing a fermentation system, formulating a sports beverage, or designing a low-GI snack, maltotriose is a versatile ingredient with scientifically backed advantages.
