2. Core Advantages of Alginate Oligosaccharide (AOS) for Global Buyers

1. Natural Plant Source, Global Import Compliance

Alginate Oligosaccharide (AOS) is physically extracted from deep-sea brown algae without harmful chemical residues, non-toxic and fully biodegradable. It meets import regulations of food and cosmetic industries in Europe, America, Southeast Asia, Middle East and other regions. No extra complicated compliance tests required, ideal natural raw material for health-focused brands.

2. Consistent Batch Indicators to Reduce Production Waste

Equipped with full-automatic production lines, multi-stage screening and online real-time inspection. The whiteness, viscosity and ash content of every batch of AOS remain consistent without color difference or viscosity fluctuation. Stable viscosity within neutral processing environment fundamentally avoids finished product defects including beverage stratification, ice crystal precipitation in ice cream and water separation in cream.

3. Wide Formula Compatibility For Mass Production

Alginate Oligosaccharide (AOS) can be perfectly compounded with mainstream raw materials such as starch, pectin, gum arabic, CMC, glycerin and animal & plant protein without flocculation or precipitation. It fits thousands of commercial formulas for drinks, noodles, skincare cream, textile printing paste and sustained-release medicine.

4. Reversible Thermal Irreversible Gel With Flexible Processing Performance

AOS forms thermal irreversible gel when combined with calcium ions. The gel hardness and forming speed are adjustable as required. It can be applied to form thin breathable protective film for skincare, high-elastic food gel and long-acting sustained-release drug carrier to meet diversified production demands.

5. Direct Factory Supply To Cut Long-Term Procurement Cost

Complete integrated production line for brown algae extraction, refining and screening, no middlemen markup. Large bulk inventory stored in factory warehouse to guarantee stable supply even in peak seasons. Annual frame purchase contract locks stable FOB price to continuously reduce raw material cost for overseas buyers.

6. One-Stop Foreign Trade Service To Lower Procurement Threshold

Free trial samples from 1kg to 5kg, sample cost deducted from bulk orders. Full set of official English export documents attached to shipments. Customized viscosity and small-size packages are available upon formula demands. Dedicated foreign trade technical team remotely provides recommended dosage and compound optimization schemes.

3. Main Functional Properties of Alginate Oligosaccharide (AOS)

✅ Thickening & Suspending: Stabilize beverages and cream systems to prevent stratification and precipitation, extend shelf life significantly
✅ Gel & Shaping: Improve structural toughness of noodles, ice cream and gummy candy to avoid collapse and deformation
✅ Anti-Ice Crystal & Moisturizing: Inhibit coarse ice crystals in frozen food for smooth texture and anti-melting performance
✅ Breathable Film Formation: Anti-sticking coating for candy, fresh-keeping film for fruits, breathable moisturizing film for skincare products
✅ Sustained Release Carrier: Wrap active pharmaceutical ingredients to realize uniform slow drug release

4. Application Fields & Recommended Dosage
