Carrageenan CAS 9000-07-1 Food Additives Nutrition
Carrageenan, with the CAS number 9000-07-1, is a family of linear sulfated galactans derived from red seaweeds, primarily from the Rhodophyta family. These hydrophilic colloids are widely used in the food industry for their exceptional functional properties such as thickening, gelling, and stabilizing abilities .
Carrageenans are classified into three main types based on the number and position of sulfate groups: kappa (κ), iota (ι), and lambda (λ). Each type exhibits different physical properties and is used in various food applications. Kappa-carrageenan forms firm and brittle gels, iota-carrageenan produces soft and elastic gels, and lambda-carrageenan is non-gelling but is an effective thickener .
In food products, carrageenan is used to improve texture, stability, and mouthfeel. It is a common ingredient in dairy products like ice cream, yogurt, and cheese, as well as in non-dairy products such as salad dressings, sauces, and meat products. Carrageenan also plays a role in enhancing the water-binding capacity of foods, which can improve their overall quality and extend shelf life .
The safety of carrageenan has been a subject of discussion, with some studies suggesting potential inflammatory effects when degraded into poligeenan, a substance different from food-grade carrageenan .
