Introduction
1. Carrageenan (also called carrageen gum) is a kind of natural polysaccharide hydrophilic gum extracted from sea plants - red algae and, normally, is white or yellow in the form of powder, odourless and tasteless. The gel-forming Carrageenan is of heat reversibility. I. E., the gel turns into solution when being heated and turns back to gel again as soon as the solution is cooled. Carrageenan possesses very favourable water solubility and starts melting at 70, and absolutely melts at 80. Meanwhile, it features fine stability so that long-term placement may not reduce its gelling intensity and viscosity. The product won't be hydrolyzed even if heated in a neutral and alkaline solutions.
2. In practical applications, weak gel carrageenan is generally used to thicken ice cream and milk beverages, combined with the weak gel network structure produced by the carrageenan-protein system, coupled with the effects of calcium salt, etc., can give the material a certain consistency.
3. In ice cream, carrageenan is combined with mannan and milk protein to form a weak gel network, giving ice cream shape retention, resistance to heat denaturation, preventing slurry separation, inhibiting ice crystal growth, and improving the expansion rate and melting rate of ice cream.
4. Cocoa milk is the most used milk beverage of carrageenan. It requires a weak gel formed by a carrageenan-protein system to provide the consistency of cocoa powder, while the weak gel formed by carrageenan will not damage the taste produced by other substances.
Application
1. In the food industry, carrageenan can be used as a gelling agent, thickener, stabilizer, suspending agent and clarifier, and can be used in products such as soft candy, jelly, sausage, canned meat, ice cream, beverage, condiment, milk, bionic food, jam, canned thick soup, beer, bread, pet food and so on.
2. In the pharmaceutical industry, it can be used as a medicine suspending agent and dispersant, and can be used to produce capsule products etc.
3. In the daily chemical industry, it can be used in toothpaste, detergent, cosmetics and air freshener production.
