Description

Fructooligosaccharides CAS NO 308066-66-2 are a class of prebiotic oligosaccharides derived from fructose units. They are valued for their functional properties as soluble dietary fibers and selective substrates for beneficial gut microbiota. This product is essential for manufacturers in the nutraceutical, functional food, and animal feed industries seeking to enhance the nutritional profile and health benefits of their formulations.

Application

• Functional Food & Beverage Ingredient: Used as a prebiotic fiber and sugar substitute in dairy products (yogurt, milk drinks), baked goods, cereals, and health beverages to promote digestive health.
• Dietary Supplement Formulation: Incorporated into capsules, tablets, and powder blends as a key prebiotic component to support gut microbiome balance and immune function.
• Infant & Clinical Nutrition: Applied in specialized infant formula and medical nutrition products to mimic the bifidogenic effects of human milk oligosaccharides.
• Animal Feed & Pet Food Additive: Utilized as a zootechnical additive to improve gastrointestinal health, nutrient absorption, and overall performance in livestock and companion animals.
• Pharmaceutical Excipient: Serves as a functional carrier or stabilizer in certain probiotic and synbiotic pharmaceutical preparations.

Quality Control

Our Fructooligosaccharides are produced and tested to meet stringent quality standards suitable for food, nutraceutical, and feed applications. Quality assurance protocols align with principles of Food Chemical Codex (FCC) and Good Manufacturing Practice (GMP). Each batch is supported by a comprehensive Certificate of Analysis (COA) verifying key parameters such as purity, oligosaccharide profile, and microbiological safety.

Storage

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