Food Additive Carrageenan,Konjac Jelly Powder Refined Kappa Carrageenan
Carrageenan Jelly Powder is a extract of hydrocolloid red seaweed, with functions of gel, suspension, emulsion, thickener, stability and water-holding etc.
Application of Carrageenan Jelly Powder
Carrageenan Jelly Powder is stable in neutral and alkaline solution, it won’t be hydrolyzed when heated. But in acidic solution (especially the pH value ≤ 4.0), Carrageenan is prone to acid hydrolysis with gel strength and viscosity decreased. Besides, under neutral conditions, if carrageenan prolonged heating at high temperatures, it will be hydrolyzed, and it’s gel strength would be reduced. All types of carrageenan can be dissolved in hot water and hot milk. When dissolved in hot water, it will form a viscous free running solution with transparent or slightly milky. Carrageenan will absorb water to expansion but cannot be dissolved in cold water.
Application of Carrageenan:
l Carrageenan is econimic & highly elastic compared with agar;
l Carrageenan has high freezing & melting point compared with gelatin;
l Carrageenan has no special requirements for PH condition and solubility of sugar compared with pectin. Carrageenan is stable in neutral & alkaline solution.
Used in fudge production
Fruit jelly made with carrageenan has below characters:
Concentrated fruityodour, moderate sweetness, refreshing and none-stick with teeth and better transparency and lower price than agar. When it is added into normal hard candy and fudge, Carrageenan makes fudge low sticky and stable as well as tastes smoothly.
