Xanthan Gum

Introduction of Xanthan Gum:
1. Xanthan gum, a kind of food additives, is a biosynthesis gum in the shape of white or cream-color and free-flowing powder. It takes corn starch as the main ingredient.
2. Fermented by microorganism Xanthomonas under specific conditions, it is made into high molecular polymer polysaccharide after being refined, dried and grinded. The molecular structure of xanthan gum determines its special properties: thickening, suspension, salt resistance, temperature resistance, acid and alkali-resistance, and anti-shearing.
3. Xanthan gum is widely used in food, pharmaceutical, pesticide, oil drilling, on-washing, textile printing and dyeing, tobacco, paper, fire and many other industries.
4. As a leading food additives and food ingredients manufacturer in China, we can provide you with high quality xanthan gum.

Properties of Xanthan Gum:
1) Prominent high viscosity and water solubility: 1％ of xanthan gum solution viscosity equals to 100 times of gelatin solution viscosity with the same concentration. So its thickening and viscosity effects are significant.
2) Unique characteristic of pseudoplastic rheology: Under the same temperature, xanthan gum solution can do reversible changes between sol and gel according to the changes of the mechanical outside forces. So it is a highly efficient emulsion stabilizer.
3) Excellent stability of temperature and PH: In a large scope of temperature(-18－120℃)and PH(2-12), xanthan gum can keep its original viscosity and performance. So it has reliable viscosity effect and freeze-thaw stability.
4) Satisfying compatibility: Xanthan gum can form a stable thickening system with acid, alkali, salt, enzymes, surfactants, preservatives, thickeners, oxidants, and other chemicals. At the same time, it can remain its rheology.
5) Under the proper proportion, it can own obvious rheology when combined with locust bean gum and other gums.
