What is xanthan gum
Recently, such a statement circulated on the Internet: a lot of porridge house and a snack provided very thick porridge, in fact, not boil out the effect, but the use of thickeners. Reporter survey found that although many businesses denied the use of a thickening agent, but there are a lot of people selling additives both in the market and by internet.
Food thickener is to be dissolved or dispersed in water, can increase the viscosity of fluid or semi fluid food, and can keep the location system relatively stable hydrophilic food additives. Thickener molecule contains many hydrophilic groups, such as hydroxyl, carboxyl, amino and carboxylic acid, can happen hydration and water molecules. Usually, food thickeners are colloid polymer hydrophilic.
Xanthan gum is the main component of the thickener, what is xanthan gum? Xanthan gum also known as yellow gum, xanthan, Xanthomonas campestris polysaccharide, is a kind of fermentation produced by false Xanthomonas single spore polysaccharide, cabbage black rot by Xanthomonas campestris to carbohydrate as the main raw material, through the aerobic fermentation of biological engineering technology, cut off the 1, 6- the glycosidic bond, branched chain after the open, at 1, an acidic extracellular 4- key synthesis of straight chain composed of outer polysaccharide. In 1952 by the United States Department of agriculture Illinois PIO in northern Lille Institute isolated cabbage black rot Xanthomonas, and make the cabbage extract into water-soluble acidic extracellular heteropolysaccharide obtained.
Xanthan gum solution has the characteristics of low concentration and high viscosity (100 times 1% aqueous solution viscosity of gelatin is equivalent to), is a kind of high efficient thickener. Since 1996, as the use of food additives permitted since, xanthan gum has been widely accepted by the food industry, because it can at low concentrations and provide excellent processing and storage stability. According to the hygiene standards for use of food additives in China, xanthan gum can be used in bread, ice cream, milk products, meat products, jam, jelly, beverage.
