Description

4'-Galactosyllactose is a complex, prebiotic oligosaccharide derived from lactose. This compound is of significant commercial interest for its role as a key human milk oligosaccharide (HMO) analog, mimicking the beneficial biological functions found in natural sources. It is primarily utilized by manufacturers in the infant formula, nutraceutical, and functional food industries seeking to enhance product nutritional profiles and support digestive health.

Application

• Infant Formula Fortification: As a critical HMO, it is added to formula to more closely replicate the composition and prebiotic benefits of human breast milk, supporting a healthy gut microbiome in infants.
• Dietary Supplements & Nutraceuticals: Incorporated into probiotic and prebiotic supplements to promote the growth of beneficial gut bacteria (e.g., Bifidobacteria) and support overall digestive wellness.
• Functional Food & Beverage Production: Used in products like yogurts, dairy drinks, and health bars to add prebiotic fiber content without significantly altering sweetness.
• Pharmaceutical Research & Development: Serves as a standard or intermediate in R&D for studying gut health, immunomodulation, and the development of new therapeutic agents.
• Microbiological Culture Media: Employed as a selective substrate in laboratory settings for the cultivation and study of specific bacterial strains.
• Cosmeceuticals: Investigated for potential applications in skincare formulations for its purported skin microbiome-balancing and moisturizing properties.
