D-Tagatose

D-Tagatose is a high-purity sugar-units supplied for industrial and specialty chemical applications. Contact our team for specifications, packaging options and lead times.

1. Food & Beverage Industry

Low-Calorie Sweetener:

D-Tagatose is used as a sugar alternative in dietary foods, sugar-free products, and beverages due to its similar sweetness and physical properties to sucrose but much lower caloric content.

Diabetic and Keto-Friendly Products:

Because it has a very low glycemic index (~3) and does not significantly raise blood glucose or insulin levels, it is ideal for diabetic and ketogenic foods.

Functional Food Additive:

D-Tagatose is a prebiotic that promotes beneficial gut flora. It also exhibits anti-hyperglycemic properties, enhancing its value in health-oriented formulations.

Dairy & Baked Goods:

It is heat stable and can undergo Maillard reactions, giving browning and flavor development in baked goods, dairy desserts, and cereals.

2. Pharmaceutical and Nutraceutical Uses

Antidiabetic Adjunct:

D-Tagatose has shown potential in improving glycemic control in type 2 diabetes by reducing postprandial glucose spikes and enhancing hepatic glycogen synthesis.

Weight Management:

Its low caloric value, satiating effect, and non-stimulatory impact on insulin make it suitable for weight control supplements and functional foods.

Antioxidant & Anti-inflammatory Potential:

Emerging studies suggest D-tagatose may help reduce oxidative stress and inflammatory markers, aiding in metabolic syndrome management.

3. Oral Health Products

Unlike sucrose, D-Tagatose is non-cariogenic - it does not promote tooth decay because oral bacteria cannot effectively ferment it. This makes it suitable for use in sugar-free gums, mints, and toothpaste.

4. Biotechnology and Research

Enzymatic Substrate:

D-Tagatose is a useful substrate in the study of ketohexose isomerases and sugar metabolism enzymes, and in biocatalysis research.

Raw Material for Rare Sugar Synthesis:

It is used in the biosynthesis of rare sugars, which are gaining importance in pharmaceuticals and nutraceuticals for their bioactivity.

✅ Low-Calorie Sweetening Power

Offers ~92% the sweetness of sucrose with only 1.5 kcal/g, helping reduce overall calorie intake while maintaining palatable sweetness.

✅ Low Glycemic Index

With a GI around 3, D-tagatose is safe for diabetics, as it does not lead to blood sugar spikes or large insulin responses.

✅ Promotes Gut Health

Acts as a prebiotic, selectively supporting the growth of beneficial bacteria like Lactobacillus and Bifidobacterium, contributing to gut and immune health.

✅ Non-Cariogenic

Does not promote dental caries or acid production by oral bacteria, making it safe for use in dental-friendly products.

✅ Supports Weight Management

Its low energy content and minimal impact on blood glucose/insulin levels help manage hunger and body weight, making it ideal for diet plans.

✅ Heat Stability

D-Tagatose maintains thermal stability, allowing it to be used in cooked and baked goods without degradation or loss of sweetness.

✅ Metabolic Benefits

Demonstrated effects in reducing triglycerides, improving insulin sensitivity, and lowering post-meal glucose levels in clinical studies.

D-Tagatose (CAS 87-81-0) is a rare sugar with the taste and texture of sucrose but with far fewer calories and major health benefits. It supports blood sugar control, weight management, oral health, and gut microbiome balance. Its stability and sweetness make it an excellent alternative in a wide range of food, health, and pharmaceutical applications. As consumer demand for healthy, functional, and low-calorie foods increases, D-tagatose offers an ideal natural solution.
