Description

Stachyose is a naturally occurring tetrasaccharide, a member of the raffinose family of oligosaccharides (RFOs), with the CAS registry number 54261-98-2. This compound serves as a valuable functional ingredient and a critical standard for analytical research, prized for its prebiotic properties and role in plant physiology. It is essential for manufacturers and researchers in the nutraceutical, food science, and pharmaceutical industries seeking high-purity ingredients for product development and quality control.

Application

• Prebiotic & Nutraceutical Formulations: Utilized as a functional food ingredient to selectively promote the growth of beneficial gut microbiota (e.g., bifidobacteria).
• Pharmaceutical Reference Standard: Serves as a high-purity analytical standard for HPLC, LC-MS, and other chromatographic methods in quality control and research laboratories.
• Food & Beverage Industry: Incorporated as a low-calorie sweetener and texturizing agent in specialized dietary products and functional beverages.
• Biochemical & Physiological Research: Used in studies of carbohydrate metabolism, plant biology (as a transport sugar), and intestinal health.
• Cosmetic & Personal Care: Employed in skincare formulations for its humectant and moisturizing properties.
• Animal Feed Additive: Applied in premium feed to improve gastrointestinal health and nutrient absorption in livestock.

Quality Control

Our Stachyose is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. We offer grades suitable for food, nutraceutical, and research applications, with specifications aligning with industry standards. A comprehensive Certificate of Analysis (COA), detailing purity, identification, and impurity profiles, is provided with each shipment to guarantee product integrity and traceability.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider desiccated conditions to prevent moisture uptake and caking.
