Carrageenan Bulk

Carrageenan Description

Carrageenan, a type of natural polysaccharide hydrocolloid, is found in certain red seaweed varieties. These carbohydrates can form thick solutions or gels in aqueous media at low concentrations.

Carrageenan comes in the form of a small, white, or yellowish powder that is odorless and tastes good. It is heat-reversible. The solution can be dissolved after heating up, and it can gel while cooling. The gel is stable and will not decrease in strength or viscosity over time. Carrageenan, when used with konjac and locust bean gum and xanthan can be used to alter gel properties and make gel elastic.

Carrageenan Applications

To enhance the texture and microstructure in gels, Iota and Kappa carrageenans are widely used in the food industry.

Kappa is a great option to thicken, water-binding, and gelling. However, Iota exhibits viscoelastic characteristics to create an ideal food system that is gelled.

The use of them in concrete preparation could result in a high compressive strength, flexural strength and impact toughness. Carrageenan is mostly used in dairy and meat products.
