Description

D(+)-Raffinose Pentahydrate is a high-purity trisaccharide sugar derived from natural sources, widely recognized for its role as a prebiotic and a stable biochemical reagent. Its value lies in its ability to selectively promote beneficial gut microbiota and serve as a precise standard in analytical and research applications. This product is essential for manufacturers and researchers in the pharmaceutical, nutraceutical, food science, and life science research industries seeking a reliable and well-characterized carbohydrate.

Application

• Prebiotic Formulations: Used as a functional food ingredient and in dietary supplements to stimulate the growth of beneficial bacteria like bifidobacteria in the gut.
• Pharmaceutical Research: Serves as a standard, reference material, or excipient in drug development and quality control laboratories.
• Microbiology & Cell Culture: Employed as a carbon source in selective media for microbial cultivation and in various cell biology studies.
• Food Science: Acts as a mild sweetener, texture modifier, and humectant in specialized food products, leveraging its low glycemic index.
• Diagnostic Reagents: Utilized in the formulation of biochemical kits and reagents for clinical diagnostics and enzymatic assays.
• Biochemical Studies: Functions as a substrate for enzymes like α-galactosidase in metabolic pathway research and enzymology.
