Abstract Carrageenan (CGN) is a seaweed-derived high molecular weight (Mw) hydrocolloid, primarily used as a stabilizer and thickener in food. The safety of CGN regarding its use in food is reviewed. Based on experimental studies in animals, ingested CGN is excreted quantitatively in the feces. Studies have shown that CGN is not significantly degraded by low gastric pH or microflora in the gastrointestinal (GI) tract. Due to its Mw, structure and its stability when bound to protein, CGN is not… 

Gastrointestinal Tract Digestion and Carrageenan: How Misconceptions have influenced the Understanding of Carrageenan Safety

Carrageenan (CGN) is a naturally occurring fiber isolated from various species of red seaweeds (class Rhodophyceae). It has been safely consumed for hundreds of years and today is approved for use in

Experimental Evaluation of Food-Grade Semi-Refined Carrageenan Toxicity

The findings suggest that oral exposure to E407a through rats results in the development of intestinal inflammation, and is associated with altered small and large intestinal morphology.

Carrageenans from the Red Seaweed Sarconema filiforme Attenuate Symptoms of Diet-Induced Metabolic Syndrome in Rats

Red seaweed Sarconema filiforme supplementation improved symptoms of high-carbohydrate, high-fat diet-induced metabolic syndrome in rats and modulated gut microbiota without changing the Firmicutes to Bacteroidetes ratio.

Carrageenan Safety

  • 2015
There is no confusion regarding the safety of carrageenan. Carrageenan is a safe and natural fiber extracted from seaweed [1]. It is an indigestible polysaccharide that is commonly used in foods as a

Chronic Carrageenan Toxicity and the Possible Ameliorative Role of Diacerein in Experimental Animals

It appears that carrageenan can induce oxidative damage in the thyroid gland of rats and diacerein has an ameliorative effect against this damage.

Re‐evaluation of carrageenan (E 407) and processed Eucheuma seaweed (E 407a) as food additives

The Panel concluded that the existing group acceptable daily intake (ADI) for carrageenan and processed Eucheuma seaweed (E 407a) of 75 mg/kg bw per day should be considered temporary, while the database should be improved within 5 years after publication of this opinion.

Carrageenans: are they useful or detrimental?

It is concluded that the properties of carrageenans depend primarily on the type and molecular weight of macromolecules.

Digestive fate of dietary carrageenan: Evidence of interference with digestive proteolysis and disruption of gut epithelial function

The possibility that commercial Carrageenans (E407) (CGN) may reduce protein and peptide bioaccessibility, disrupt normal epithelial function, promote intestinal inflammation, and consequently compromise consumer health is raised.



A Critical Review of the Toxicological Effects of Carrageenan and Processed Eucheuma Seaweed on the Gastrointestinal Tract

The lack of carcinogenic, genotoxic, or tumor-promoting activity with carrageenan strongly supports continuing such an ADI, and JECFA, during its most recent review in 2001, continued this recommendation.

There has not been a comprehensive review of the CGN in vitro literature, which has reported a wide range of biochemical effects related to this compound, so an extensive effort has been made to evaluate as much of this literature as possible.

Intestinal uptake of carrageenan: distribution and effects on humoral immune competence.

Carrageenan is the generic name given to high-molecular-weight( 100,000 daltons) sulphated polygalactans derived from certain species of red algae. Three basic types can be isolated: k, i, and 1.

It is demonstrated that exposure to undegraded as well as to degraded carrageenan was associated with the occurrence of intestinal ulcerations and neoplasms, and the widespread use of carrageENan in the Western diet should be reconsidered.

Faecal excretion of degraded and native carrageenan by the young rat

Hawkins & Yaphe (1965) have shown that when native, undegraded carrageenan is fed to young rats, at levels of 2 to 20% in the diet, it is 90-100% excreted in the faeces. No comparable results appear

Enhancing effect of carrageenan on the induction of rat colonic tumors by 1,2-dimethylhydrazine and its relation to beta-glucuronidase activities in feces and other tissues.

Since it has been demonstrated that a high level of fat is a dietary factor in the etiology of colon cancer, the effect of carrageenan on colonic tumors in rats fed a semipurified control diet containing an ordinary level offat was studied.
