Prebiotics & Dietary Fiber
Natural Water-Soluble Prebiotic Dietary Fiber Focused on Intestinal Microecology Regulation
Fructo-oligosaccharides (abbreviated as FOS) are functional oligosaccharides enzymatically synthesized by microbial fructosyltransferase with sucrose as the substrate, classified as natural polymeric water-soluble dietary fiber. They mainly consist of kestose, nystose and 1F-fructofuranosylnystose.
Compliance codes for food additives: CNS No. 20.008, INS No. 955, CAS No. 308066-66-2. Manufactured in accordance with GB 2760 and GB 1903.15-2016 National Food Safety Standard: Food Additive Fructo-oligosaccharides. It is categorized as a prebiotic, sweetener modifier and dietary fiber fortifier, also recognized worldwide as a premium intestinal prebiotic raw material.
Main Components: Mixture of kestose, nystose and 1F-fructofuranosylnystose (fructooligosaccharides)
Core Indicators: Total FOS content ≥95% (customizable specifications including 55%/90%/95% available), controllable degree of polymerization DP2~DP5
Appearance: White to pale yellow crystalline powder or granules, odorless, fresh and sweet taste similar to sucrose, free of visible impurities
Stability: Excellent stability under weak acid to neutral conditions, good tolerance to high-temperature short-time processing. Shelf life: 24 months when sealed, protected from light and stored in cool & dry environment
Solubility: Freely soluble in cold and hot water with clear aqueous solution; pH value of 5% aqueous solution ranges from 4.5 to 7.0, featuring strong compatibility with various food matrices
➢ Comprehensive Global Regulatory Approval
Compliant with China national standard GB 1903.15 and permitted for use as required by production in GB 2760. Approved by global leading authorities including FDA GRAS, JECFA, EFSA, MFDS (South Korea) and CAC, supporting hassle-free export to Europe, America, Southeast Asia, Japan, South Korea and other regions.
➢ Excellent Processing Adaptability
Superior water solubility for rapid dissolution; thermally stable under neutral and weakly acidic environments, compatible with multiple manufacturing processes such as sterilization, spray drying, baking and boiling with consistent batch-to-batch physical and chemical indicators.
➢ Outstanding Health Benefits
Produced via natural enzymatic hydrolysis, low-calorie, low-GI and purely prebiotic with no digestion and absorption in the small intestine of human body.
➢ Clean Label Friendly
Can be labeled directly as "Fructo-oligosaccharides", "Water-Soluble Dietary Fiber" or "Prebiotic", fully aligning with the clean label trend for natural and healthy consumer products.
➢ Excellent Formulation Synergy
Compatible with natural high-intensity sweeteners such as erythritol, allulose, steviol glycosides and monk fruit extract to optimize flavor profile. High compatibility with whey protein, plant hydrocolloids and milk powder without altering the intrinsic flavor of raw materials.
Undegradable by human digestive α-amylase and barely absorbed in the small intestine, with a calorific value of approximately 1.2 kcal/g, far lower than 4 kcal/g of sucrose. An ideal sweetening and bulking ingredient for low-sugar and sugar-free formulations.
Extremely low GI value avoids sharp postprandial blood glucose spikes and does not require insulin for metabolism, suitable for diabetics, blood glucose control population and weight-loss groups.
Reaches the large intestine intact and is selectively fermented exclusively by beneficial intestinal flora including Bifidobacterium and Lactobacillus, selectively boosting the proliferation of good bacteria and inhibiting colonization of harmful pathogens such as Escherichia coli and Clostridium perfringens to precisely rebalance intestinal microecology, delivering higher targeting performance than broad-spectrum dietary fibers.
Fast dissolution rate with clear and transparent solution; resistant to thermal degradation and discoloration during baking, pasteurization and UHT ultra-high temperature instantaneous sterilization under neutral and weakly acidic conditions, ensuring stable shelf-life performance of finished products.
Cannot be fermented by oral microorganisms to produce organic acids, preventing enamel erosion and dental caries, ideal for children’s snacks, chewing gums and oral care products.
Generates abundant short-chain fatty acids (SCFAs) via flora fermentation to lower colonic pH, soften stool and increase fecal volume for regular intestinal peristalsis, alleviating constipation and irregular defecation. Strengthens intestinal epithelial mucosal barrier, reduces intestinal leakage and the risk of chronic intestinal inflammation.
Creates satiety in the stomach to delay gastric emptying and prevent overeating. Short-chain fatty acids participate in systemic metabolic regulation to improve lipid metabolism and support weight management programs.
Acidified intestinal microenvironment facilitates dissociation of calcium, magnesium, iron, zinc and other mineral ions, boosting their absorption in the small intestine, beneficial for bone development and trace element supplementation for infants, the elderly and pregnant & lactating women.
Stimulates the activity of immune cells in gut-associated lymphoid tissue and downregulates inflammatory factors through stable intestinal flora and intact intestinal mucosa, building the first line of systemic immune defense starting from the gut.
Binds partial bile acids in the intestinal tract for excretion, promoting reverse cholesterol transformation in the liver and assisting in the reduction of total serum cholesterol and low-density lipoprotein to support cardiovascular metabolic health.
