Description

D-Tagatose is a naturally occurring ketohexose monosaccharide, an isomer of fructose, with the CAS registry number 87-81-0. It serves as a versatile, low-calorie sweetener with a clean, sugar-like taste and significant prebiotic functionality, making it a valuable ingredient for modern food and health product formulations. This compound is primarily sought after by manufacturers in the food & beverage, nutraceutical, and pharmaceutical industries seeking to develop reduced-sugar, diabetic-friendly, and gut-health-promoting products.

Application

• Food & Beverage Sweetener: Used as a bulk, low-calorie sweetener in baked goods, cereals, soft drinks, and dairy products, offering approximately 92% of the sweetness of sucrose.
• Prebiotic & Dietary Supplement: Functions as a prebiotic to selectively promote the growth of beneficial gut bacteria (e.g., Bifidobacteria), supporting digestive health and immune function.
• Diabetic-Friendly Formulations: Ideal for sugar-free and low-glycemic index (GI) products, as it has a minimal impact on blood glucose and insulin levels.
• Pharmaceutical Excipient: Employed as a taste-masking agent and a carrier in chewable tablets, syrups, and other oral dosage forms.
• Cosmetic & Personal Care: Acts as a humectant and skin-conditioning agent in moisturizers, lotions, and other skincare formulations.
• Chemical Intermediate: Serves as a chiral building block in organic synthesis for the production of more complex bioactive molecules.

Quality Control

Our D-Tagatose is produced and tested to meet stringent quality standards suitable for food, nutraceutical, and pharmaceutical applications. We ensure compliance with relevant specifications, including Food Chemicals Codex (FCC) and other recognized industry guidelines. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters, which is available upon request to guarantee supply reliability and product consistency for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
