Arabinogalactan is an important food additive with a wide range of functions and applications.
1. It provides excellent thickening effects. As a high-molecular-weight polymer, arabinogalactan serves as a thickening agent in various food systems—such as beverages, sauces, and dairy products—increasing viscosity while improving mouthfeel and stability.
2. It possesses gelling properties; under appropriate conditions, it forms a gel. It is widely used in the production of gel-based foods like gummies, jellies, and puddings, and can also enhance the gelling performance of other hydrocolloids such as gelatin and pectin.
3. It exhibits good emulsifying properties, making it suitable for use as an emulsifier in dairy products and fat substitutes. By reducing the surface tension between water and oil, it stabilizes oil droplets within the aqueous phase, thereby enhancing the stability of dairy products.
4. It improves foam stability and reduces liquid drainage, thereby enhancing the quality of aerated food products.
5. It possesses anti-crystallization properties, inhibiting the formation and growth of crystal nuclei. This slows down the rate of crystallization, helping to prevent unwanted crystallization in products such as confectionery.

Application
1. In the fields of medicine and healthcare:
Arabinogalactan exhibits immunomodulatory properties, enhancing the body's immune function and its ability to combat pathogens. It may also possess anti-tumor activity, exerting an inhibitory effect on certain tumor cells. Furthermore, arabinogalactan helps balance gut microbiota by promoting the growth of beneficial bacteria; this positively impacts intestinal health and can alleviate issues such as intestinal inflammation.
2. In the food industry:
Arabinogalactan is commonly used as a thickener, stabilizer, and emulsifier; it improves the texture and mouthfeel of food products while enhancing their stability and shelf life.

Description About Arabinogalactan
Arabinogalactan (AG) is a complex carbohydrate found in plants like larch trees and certain foods. Its health benefits primarily involve supporting immune function and digestive health, and it is generally recognized as safe for use as a dietary supplement.
The usage level of arabinogalactan is approximately 1%–1.5% in soy milk, ice cream, frozen confections, jelly, beverages, and canned goods; about 0.2%–0.5% in vinegar, soy sauce, vegetable oil, fruit juice, meat juices, and vegetable juices; and around 0.05% in bread, cakes, noodles, and pasta. Additionally, arabinogalactan finds application in fields such as coatings, packaging, detergents, and pharmaceuticals.
Arabinogalactan is highly water-soluble and forms stable solutions. In the food industry, it serves as a thickener, emulsifier, and stabilizer, improving the mouthfeel and texture of food products. In the medical field, it exhibits immunomodulatory effects; it activates immune cells—such as macrophages and natural killer cells—thereby boosting the body's resistance and helping to prevent or alleviate infections. Additionally, it possesses prebiotic properties that promote the growth and proliferation of beneficial gut microbiota, improve intestinal health, and maintain the balance of the intestinal micro-ecosystem.
