If you want to understand xanthan gum, first of all, what is xanthan gum? Xanthan gum, also known as Hansen gum, is a kind of extracellular polysaccharide produced by Xanthomonas campestris by fermentation engineering with carbohydrate as the main raw material (such as corn starch). D-glucose, D-mannose and D-glucuronic acid are high molecular weight polysaccharides with a ratio of 2:2:1.
The ratio of acetic acid to pyruvic acid depends on the strain and post fermentation conditions. The framework structure of xanthan polymer is similar to cellulose, but the uniqueness of xanthan lies in the existence of a trisaccharide side chain composed of mannose acetate, terminal mannose unit and a glucuronide between them. Such a special framework makes xanthan gum very stable. Even in acid-base environment or enzyme environment, the thickening ability of xanthan gum itself does not change much.
Xanthan gum was first discovered and produced in the United States, and then China independently discovered and cultivated xanthan gum production colonies in the 1980s. With the development of technology, China’s industrial cluster advantage has been enhanced. In the early 21st century, Chinese xanthan gum has become the most important xanthan gum producer in the world. At present, the main factors affecting the properties of xanthan gum are strain, fermentation process and post-treatment process. Therefore, not all xanthan gum are qualified xanthan gum. In the final use and procurement process, we must check the performance of the product. At present, according to some disputes in the procurement of xanthan gum, the main problems of low price xanthan gum are as follows: the proportion of different batches is different; the solubility is poor; the viscosity of the finished product is low and the stability of heat resistance and acid-base is poor; the ash content and nitrogen content of the finished product are slightly high; the microbial index is high. Therefore, it is very important to choose a reliable xanthan gum supplier. Qingdao Jiede Chemical Co., Ltd. is one of the largest xanthan gum agents of Meihua group. Product stability has been recognized by more than 30 countries and regions. The record of zero dispute has been kept for many years.
