Product Details
Products Description
Galactooligosaccharides (GOS) are naturally occurring functional oligosaccharides, hailed as the "gold standard prebiotic" in breast milk. They cannot be broken down by human digestive enzymes but can selectively promote the growth of beneficial gut bacteria such as Bifidobacteria and Lactobacilli. Recognized internationally as one of the safest and most effective prebiotic ingredients, GOS play a key role in supporting gut health.

Applications

1. Infant Formula - Core Application
Adding GOS to infant formula mimics the natural oligosaccharides found in breast milk. It helps establish a healthy gut flora in babies, boosts immunity, and helps prevent constipation. This is its most classic and demanding application.
2. Adult Nutrition & Health Foods
Widely used in adult/elderly milk powder, protein powders, and prebiotic supplements. Its primary role is to regulate gut function, aid digestion, and work synergistically with probiotics (as synbiotics) to enhance the product's health value.
3. Dairy & Beverages - Key Partner
Often added to yogurt and probiotic drinks. Acting as "food" (prebiotic) for probiotics, it significantly increases the survival rate and activity of the beneficial bacteria in the product, making the "promotes gut health" claim more genuine and effective.
4. Functional Enhancement of Everyday Foods
Used in baked goods, confectionery, cereal bars, etc. It adds a "prebiotic" or "dietary fiber" health attribute to traditional foods, meeting market demand for functional snacks. It is easy to incorporate due to its heat stability.
