  • Applications

    Maltotetraose (CAS 34612-38-9) is used as a substrate in enzymology and as a reference standard for carbohydrate analysis, especially for α-amylase and related glycosidases; it can serve as a carbohydrate ingredient in food formulations and contribute to texture with moderate sweetness; in pharmaceutical development, it may function as an excipient or bulking agent; in industrial biotech, it can act as a carbon source in fermentation media or microbial culture; and in cosmetics/personal care, it may be used as a humectant or conditioning carbohydrate additive in formulations.
