Handbook of Hydrocolloids: A Guide to Carrageenan

Carrageenan, a soluble fiber & hydrocolloid derived from red seaweed, is a natural food ingredient that has been used for hundreds of years in cooking all over the world. 

It often replaces synthetic and animal-based products (like Gelatin). It is also commonly used in vegetarian and vegan diets and lifestyles.

Carrageenan is used in a variety of commercial applications as gelling, thickening, and stabilizing agent, especially in food products and sauces. Aside from these functions, carrageenans are used in experimental medicine, pharmaceutical formulations, cosmetics, and industrial applications.

Kappa carrageenan with good gel properties is commonly used in confectionery. Carrageenan is a derivative of galactose, which is insoluble in cold water and gradually dissolved in hot water when heated to 60°C.

However, it is easy to be hydrolyzed in an acidic solution so that the gel force is destroyed.
However, when heated in an acidic solution, it is very easy to hydrolyze and destroy the gel force, so you should try not to use acid during the production process, or use a small amount of acid and add a buffer.

Carrageenan has a strong water absorption rate, up to 30 to 40 times, too much water in the production process will prolong the boiling time, and too little water can not fully dissolve the gelatin, which will affect the gelling ability. The general water consumption is 22 ~ 25 times that of carrageenan.

Here is the suggested carrageenan gummy candy recipe for your reference:

White Sugar: 15Kg   
Starch Syrup: 35Kg   
Carrageenan: 0.5Kg   
Locust Bean Gum: 0.15Kg   
Flavor: 60~80ml
Color: As per Req

Note: A moderate amount of fruit acid and the same proportion of buffer can also be added to the ingredients.

According to the literature, if carrageenan and locust bean gum are compounded in the ratio of 3:1 to 1:3, the strength and structure of the gel can be increased and improved, in addition to enhancing the phenomenon of overcoming dehydration shrinkage.

Is Carrageenan Safe?

An overwhelming body of evidence supports the conclusion that carrageenan is safe and suitable for use in food.

Regulatory authorities in every region of the world including the United States, Europe, China, Japan, and Brazil have found carrageenan safe for use in food.

Most recently, in July 2014, the Joint FAO/WHO Expert Committee on Food Additives (JECFA), “concluded that the use of carrageenan in infant formula and formulae for special medical purposes for infants up to concentrations of 1000 mg/L is not of concern”. The committee reviewed all studies, including those claiming negative effects of carrageenan, and concluded that carrageenan was safe, even for those most vulnerable in our population—infants.

In addition, experts from the World Health Organization have placed carrageenan in the best possible category for any food additive, noting it “does not in the opinion of the committee represent a hazard to health.”

The International Agency for Research on Cancer has found carrageenan to be non-carcinogenic. It also doesn’t cause inflammation of the gastrointestinal tract.

There are many well-known multinational companies and groups around the world that produce and supply carrageenan and its compounding products.
If carrageenan is not safe, then why are there more and more carrageenan suppliers?
