Prebiotics & Dietary Fiber
Marine-Derived Bioactive Oligosaccharides Empowering Health & Diversified Applications
Alginate Oligosaccharides (AOS) are small-molecule linear oligosaccharides manufactured from natural brown algae such as kelp, giant kelp and bladderwrack through directional enzymatic degradation, membrane separation and purification, decolorization and desalination, concentration and spray drying. They are linearly linked alternately by β-D-mannuronic acid (M) and α-L-guluronic acid (G) via 1,4-glycosidic bonds.
Food-grade Alginate Oligosaccharides complies with the national standard GB 1903.31-2018 National Food Safety Standard – Food Additive: Alginate Oligosaccharides, CNS No.: 18.030, CAS No.: 9005-32-7. Classified as thickener, stabilizer and humectant under GB 2760, it is also a marine-derived functional prebiotic and natural immunomodulatory polysaccharide derivative with multiple biological activities.
Main Components: Low-molecular-weight alginate oligosaccharides formed by alternating polymerization of mannuronic acid and guluronic acid, Degree of Polymerization (DP): 2～10
Core Indicators: Total content of alginate oligosaccharides ≥90.0%, molecular weight ≤2000 Daltons, moisture ≤8.0%, ash ≤10.0%
Appearance: White to light yellow homogeneous powder with a faint inherent marine algae odor, free of peculiar smell, caking and visible impurities. Its 10% aqueous solution is pale yellow clear liquid with low viscosity
Stability: Excellent acid, alkali and heat resistance, hardly decomposed under conventional food processing temperature and pH range. Sealed and stored in cool, dry and dark environment, shelf life reaches 24 months
Solubility: Rapidly soluble in cold water with outstanding water solubility; pH value of 10% aqueous solution ranges from 5.0 to 7.5, featuring good dispersibility and high compatibility with protein, colloids, probiotics and oil systems
➢ Regulatory Compliance: Legally applicable in China in accordance with GB 1903.31-2018 and permitted for use as needed per production requirements under GB 2760. Approved by international authoritative safety authorities including FDA GRAS, JECFA, EFSA and South Korea MFDS, with compliant application pathways in feed and agriculture sectors and zero allergenic risk.
➢ Processing Performance: Superior water solubility, resistant to high-temperature sterilization and acidic environments. Mild solution viscosity will not alter the original texture of finished products. The powder boasts good flowability, fully compatible with tableting, extrusion, boiling, fermentation and other processes, with highly stable physicochemical indicators across batches.
➢ Health Benefits: Hardly digested and absorbed by human body, low-calorie and nearly glycemic-neutral. It delivers potent prebiotic activity with multiple physiological functions including intestinal repair, antioxidation, immune regulation, bacteriostasis and anti-inflammation, suitable for broad consumer groups.
➢ Clean Label Friendly: Can be directly labeled as "Alginate Oligosaccharides" on ingredient lists with clear natural marine algae source, perfectly aligning with the development trend of clean labels for natural healthy foods, organic diets and functional health foods.
➢ Synergistic Effect: Can be compounded with inulin, polydextrose, resistant dextrin, FOS, GOS, various sweeteners, plant extracts and probiotic strains to generate synergistic effects, improving the overall antioxidant capacity and intestinal care efficacy of formulations.
Alginate Oligosaccharides can barely be degraded and absorbed by digestive enzymes in human stomach and small intestine, and only slowly fermented and utilized by intestinal flora upon reaching the large intestine. It has extremely low calorific value and scarcely participates in human energy metabolism, serving as an ideal active filler for calorie-controlled, fat-loss and low-energy formulations.
Fully soluble in both cold and hot water, yielding clear, low-viscosity and non-sticky aqueous solution. Its molecular structure remains stable under harsh processing conditions such as acidic juice environments, high-temperature baking, UHT sterilization for meat products and high-shear extrusion puffing, without precipitation, stratification or turbidity, adapting to most deep food processing scenarios.
Extremely low absorption rate in the small intestine will not cause sharp fluctuations in blood glucose after ingestion, with GI value close to zero and no burden on pancreatic insulin secretion. It can be safely and long-term added for diabetics, people with impaired glucose tolerance and those pursuing sugar control and weight loss.
Upon intact arrival at the colon, it acts as exclusive carbon source to selectively proliferate beneficial flora including Bifidobacteria and Lactobacilli, inhibit colonization of pathogenic bacteria such as Escherichia coli, Clostridium perfringens and Salmonella, rectify intestinal flora imbalance and build a healthy intestinal microecological barrier.
It possesses strong water molecule binding and water retention capacity. When added to baked pastries and grain products, it binds free water, delays starch retrogradation and aging, and maintains soft texture of cakes and breads. In meat products and sauces, it enhances water retention and cooking yield, while delivering auxiliary bacteriostatic and preservative effects.
Salivary amylase in oral cavity cannot break down Alginate Oligosaccharides, and oral cariogenic bacteria fail to metabolize it to produce acid that erodes tooth enamel. Applied in sugar-free candies, chewing gums and lozenges, it effectively reduces the incidence of dental caries.
As a rare marine-derived functional active oligosaccharide, Alginate Oligosaccharides provides comprehensive and systematic physiological care for populations with intestinal damage, low immunity, metabolic disorders, sub-health and age-related physical decline in the elderly:
It absorbs water and expands in the large intestine to increase stool volume, accelerate colonic peristalsis and improve slow-transit intractable constipation. Fermentation by gut flora generates abundant short-chain fatty acids to lower intestinal inflammation, repair damaged intestinal villi, relieve diarrhea caused by irritable bowel syndrome and flora disturbance, and restore normal intestinal peristaltic rhythm.
It absorbs water in the stomach to form hydrated gel substances, delay gastric emptying and continuously trigger satiety signals to reduce calorie intake from main meals and snacks. It physically encapsulates partial dietary fat and cholesterol in the intestine to lower lipid absorption, facilitating steady body fat and weight control.
It slows down the absorption rate of free glucose from food in the small intestine and flattens postprandial blood glucose peaks. It adsorbs bile acids in the intestine for excretion via feces, accelerates hepatic cholesterol catabolism, and helps reduce serum triglyceride and low-density lipoprotein (LDL-C) levels.
Short-chain fatty acids produced by beneficial bacteria acidify the colonic microenvironment, dissolving mineral ions including calcium, iron, zinc and magnesium to boost their transintestinal transport and absorption efficiency, assisting in alleviating senile osteoporosis and iron-deficiency anemia in females.
Butyrate-dominant short-chain fatty acids supply energy for colonic epithelial cells, close gaps between intestinal epithelial cells and ameliorate leaky gut syndrome. A complete and stable intestinal mucosal barrier activates gut-associated lymphoid tissues, enhances innate and adaptive immunity of the body, reduces the occurrence of seasonal allergies and recurrent respiratory inflammation, and delivers inherent antioxidant, free radical scavenging and anti-inflammatory activities.
