      What Makes Fructo Oligosaccharide Unique

      Fructo Oligosaccharide is a short-chain oligosaccharide composed of 3–10 fructose units that functions as a highly effective prebiotic ingredient. Its non-digestible structure allows it to reach the intestines intact, where it selectively nourishes beneficial bacteria such as Bifidobacteria.

      • Naturally occurring prebiotic fiber sourced from plants such as chicory root and bananas
      • Supports the growth of beneficial gut microbiota for digestive balance
      • Low-calorie ingredient with 30–50% the sweetness of sucrose
      • Enhances calcium and magnesium absorption in fortified food products
      • Excellent solubility and stability for food, supplement, and cosmetic formulations

      Advantages of Using Fructo Oligosaccharides

      • Digestive Health Support: Helps improve bowel regularity and promotes a healthier intestinal environment by supporting beneficial bacteria growth.
      • Low-Calorie Sweetness: Provides mild sweetness with reduced caloric impact, making it suitable for reduced-sugar and diabetic-friendly formulations.
      • Functional Food Ingredient: Commonly added to yogurt, bread, cereal, and functional beverages to enhance nutritional value and product appeal.
      • Versatile Formulation Benefits: Works effectively in supplements, pharmaceuticals, and cosmetic products due to its stability and compatibility with other ingredients.
