黃原膠是一種生物合成膠，呈類白或淡黃色粉末狀，是以淀粉為主要原料，由微生物黃單胞桿菌（Xanthomonas Campestris）在特定的培養(yǎng)基、PH、通氧量及溫度條件下經(jīng)純種發(fā)酵，再經(jīng)提煉、干燥、研磨而制成的高分子多糖聚合物。

黃原膠可廣泛應用于食品、醫(yī)藥、精細化工、農(nóng)業(yè)、石油鉆井等領(lǐng)域，與其他膠類相比，黃原膠具有以下明顯的優(yōu)越性：

1、 突出的高粘性和水溶性；

2、 獨特的假塑性流變學特征；

3、 優(yōu)良的溫度、PH值穩(wěn)定性；

4、 與酸、堿、鹽、酶、表面活性劑、防腐劑、氧化劑及其他增稠劑等共存時，具有穩(wěn)定的兼容性；

5、 與瓜爾豆膠、刺槐豆膠等其他膠類復配，具有明顯的協(xié)效性。

Brief Introduction of Xanthan Gum

Xanthan Gum, which is made mainly from starch, is a high molecular weight polysaccharide produced by fermentation with Xanthomonas Campestris under the conditions of special nutrient medium,pH,O2-supply and temperature, then precipitated, dried and milled into white-like or light-yellow free-flowing powder.

Xanthan gum can be widely used in more than twenty industrial fields, such as food, pharmaceutical, fine chemical, agriculture, oil drilling and exploitation, and so on. Compared with other kinds of colloids, xanthan gum has many advantages.

1. Outstanding viscosity-enhancing property and solubility in water.

2. Unique pseudo-plasticity rheological property of xanthan gum makes it high-efficient emulsifier and stabilizer.

3. Excellent stability to large range of temperature and pH change.

4. Satisfying compatibility with acid, alkaline, brine, enzyme, surface active agent, antiseptic, oxidant and other thickeners.

5. Perfect synergistic action when blended with guar gum, locust been gum and other colloids.
