Carrgeenan

Carrageenan has strong stability, and the dry powder is not easily degraded after long-term storage. It is also very stable in neutral and alkaline solutions, and will not be hydrolyzed even if heated, but in acid solutions (especially pH ≤ 4.0) carrageenan is prone to acid hydrolysis, and the gel strength and viscosity decrease. It is worth noting that under neutral conditions, if carrageenan is heated at high temperature for a long time, it will also be hydrolyzed, resulting in a decrease in gel strength. All types of carrageenan can be dissolved in hot water and hot milk. Dissolved in hot water, it can form a viscous transparent or slightly milky white easy-flowing solution. Carrageenan can only absorb water and swell without being dissolved in cold water.

Application of carrageenan

In the production of folded jelly, carrageenan, as a good coagulant, can replace the usual agar, gelatin and pectin. Soft candy production, using carrageenan to make transparent fruit soft candy has long been produced in the world.. Its fruit flavor is strong, sweetness is moderate, refreshing and non-sticky, and its transparency is better than agar, and its price is lower than that of agar. It is added to ordinary hard candy. It can make the product taste smoother, more elastic, less sticky and more stable. Folded ice cream production, in the production of ice cream and ice cream, carrageenan can make fat and other solid components evenly distributed, prevent the separation of milk components and the increase of ice crystals during manufacture and storage, it can make ice cream and ice cream texture fine, smooth and delicious . In the production of ice cream, carrageenan can interact with cations in milk to produce unique gelling properties, which can increase the formability and melting resistance of ice cream, improve the stability of ice cream under temperature fluctuations, and it is not easy to melt when placed.
