Description

Stachyose Tetrahydrate is a naturally occurring tetrasaccharide belonging to the raffinose family of oligosaccharides (RFOs). This compound serves as a crucial functional carbohydrate with significant prebiotic activity, selectively promoting the growth of beneficial gut microbiota. It is primarily utilized in the nutraceutical, pharmaceutical, and food science industries for its role in digestive health, as a low-calorie sweetener, and in advanced biochemical research. Its high purity and consistent quality make it an essential ingredient for formulators and researchers seeking reliable, bioactive components.

Application

• Prebiotic & Nutraceutical Formulations: Used as a functional food ingredient to stimulate the growth of bifidobacteria and lactobacilli, supporting gut health and immune function.
• Pharmaceutical Research: Employed as a standard or intermediate in metabolic studies, glycobiology research, and the development of diagnostic reagents.
• Food & Beverage Industry: Acts as a natural, low-calorie sweetener and texturizing agent in specialized dietary products, including infant formula and health foods.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its humectant and moisturizing properties, helping to improve skin hydration.
• Agricultural & Animal Feed: Investigated as a feed additive to improve intestinal health and nutrient absorption in livestock.
• Biochemical Standard: Serves as a high-purity reference standard for analytical laboratories in chromatography (HPLC, HPAEC-PAD) and spectroscopy.

Quality Control

Our Stachyose Tetrahydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for research and industrial applications. Certificates of Analysis (COA) detailing purity, identity, and specific impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a low-humidity environment to prevent absorption of water and caking.
