Arabinogalactan CAS 9036-66-2
What is Arabinogalactan?
Arabinogalactan, often referred to as larch polysaccharide, is a natural high-molecular-weight polysaccharide extracted from the xylem of coniferous trees (particularly larch). It is primarily composed of galactose and arabinose in a ratio of approximately 6:1, forming a water-soluble white to pale yellow powder through a complex branched structure (mainly connected by β-1,3 and β-1,6 glycosidic bonds). In the food industry, it is widely used as a thickener, stabilizer, emulsifier, and gelling agent, commonly found in beverages, ice cream, dairy products, sauces, and other products to improve texture and mouthfeel. Furthermore, due to its good safety and functionality, it is also used as a pharmaceutical excipient in the medical field and as a humectant and stabilizer in cosmetics.
In summary, arabinogalactan is a naturally derived, multi-functional plant polysaccharide that is widely used as a safe and effective additive in various industrial fields.

Characteristics of Arabinogalactan (AG)
Processing Functional Characteristics
1. Efficient Thickening and Stabilization
Due to its high molecular weight and excellent water-binding capacity, arabinogalactan can significantly increase solution viscosity, acting as a thickener in beverages, sauces, and dairy products, effectively improving product texture, mouthfeel, and system stability.
2. Gelling and Synergistic Effects
Under specific conditions, this polysaccharide can form a gel structure, directly used in the production of jellies, gummies, and other gel-based foods. Simultaneously, it can synergize with other colloids such as gelatin and pectin, enhancing their gel strength and performance.
3. Emulsification and Foam Stabilization
It possesses good surface activity, reducing oil-water interfacial tension and acting as an emulsifying stabilizer in dairy products and dairy fat substitutes. Furthermore, it can enhance the stability of foam structures, reduce liquid separation, and improve the quality of related food products.
4. Crystal Inhibition
By interfering with the formation and growth of crystal nuclei, arabinogalactan can effectively slow down or prevent unwanted crystallization in foods such as candies, helping to maintain the long-term stability of product appearance and texture.
Nutritional Value: Guardian of Gut Health
The nutritional value of arabinogalactan is mainly reflected in its role in promoting gut health. As a high-quality prebiotic, arabinogalactan cannot be directly digested by the human body, but it can be fermented by gut microbiota (such as Bifidobacteria and Lactobacillus), producing short-chain fatty acids, lowering intestinal pH, inhibiting the growth of harmful bacteria, and promoting the proliferation of beneficial bacteria, thereby improving the balance of the gut microecology.
Consumer Advantages: Health and Convenience
For ordinary consumers, the advantages of arabinogalactan are obvious:
Natural and Safe: Derived from natural plants and subjected to rigorous safety assessments, it can be consumed with confidence.
Multifunctional: It can serve as a dietary fiber supplement to promote gut health; it can act as a prebiotic to enhance immunity; and it also has potential antioxidant and metabolic regulatory functions.
Easy to Add: AG has good solubility and stability, and can be easily added to various foods such as beverages, dairy products, and baked goods, enhancing the nutritional value and functional properties of the products.
Improved Texture: Adding AG to food can improve texture and mouthfeel, making the product more delicate and smooth.
Potential Applications of Arabinogalactan
I. As a Food Additive (Main Application Area)
In food production, it is frequently used as a key ingredient due to its various functions such as thickening, emulsifying, stabilizing, and gelling. Typical applications and addition levels are as follows:
Thickening and Gelling: In beverages, sauces, and dairy products, it acts as a thickener to improve texture and mouthfeel; in jellies, puddings, and soft candies, its gelling properties or synergistic effects with other colloids (such as pectin) are utilized to form stable gels.
Emulsification and Stabilization: In ice cream, dairy products, and dairy fat substitutes, it acts as an emulsifier to improve system stability; it also stabilizes foam structures and inhibits unwanted crystallization in foods such as candies.
Typical Addition Levels:
1% - 1.5%: Commonly used in soy milk, ice cream, jelly, canned goods, etc.
0.2% - 0.5%: Used in condiments and liquid foods such as vinegar, soy sauce, fruit juice, gravy, and vegetable oil.
Approximately 0.05%: Used in baked goods and noodle products such as bread, cakes, and noodles.
II. Other Application Areas
Pharmaceutical Field: Due to its good biocompatibility and bioactivity, it is being studied as a drug carrier and shows potential for immunomodulatory (such as macrophage activation)
Cosmetics Field: As a film-forming agent and humectant, it is added to facial cleansers and hair care products to improve product performance.
Industrial Field: Exploratory applications are also found in coatings, packaging materials, and detergents. Furthermore, due to its similar properties to gum arabic, it can be used to some extent as a substitute.
The core value of arabinogalactan lies in its use as a safe and multifunctional natural food ingredient, widely applied in the texture improvement and stabilization of various foods. At the same time, its expanded applications in the pharmaceutical, cosmetic, and industrial fields demonstrate the diverse potential of this natural polysaccharide.
