Carrageenan Might Be Causing Stomach Aches Carrageenan is a commonly used food additive that is extracted from red seaweed by using powerful alkali solvents. Carrageenan is the magic ingredient used to de-ice frozen airplanes sitting on tarmacs during winter storms. It is not unreasonable to speculate that normal gastric acid...may act upon ingested carrageenan and convert some of which is ingested to the lower molecular weight poligeenan during the actual process of digestion. www.rense.com /general74/glue.htm   (1070 words)

Carrageenan Carrageenan (E407) is a collective term for polysaccharides prepared by alkaline extraction (and modification) from red seaweed (Rhodophycae), mostly of genus Chondrus, Eucheuma, Gigartina and Iridaea. Carrageenans are linear polymers of about 25,000 galactose derivatives with regular but imprecise structures, dependent on the source and extraction conditions [292]. Carrageenan is also used as a binder in cooked meats, to firm sausages and as a thickener in toothpaste and puddings. www.lsbu.ac.uk /water/hycar.html   (669 words)

CHAPTER 3 - PRODUCTION, PROPERTIES AND USES OF CARRAGEENAN Carrageenans are commercially important hydrophilic colloids (water-soluble gums) which occur as matrix material in numerous species of red seaweeds (Rhodophyta) wherein they serve a structural function analogous to that of cellulose in land plants. Native carrageenans from different algae may be regarded as varying mixtures of the limit polysaccharides and intermediate hybrids ranging in degree of anhydridation and 2-sulfation of the 1,4-linked units. Carrageenan is used in combination with locust bean and guar galactomannans as a gelling agent in pet foods. www.fao.org /docrep/X5822E/x5822e05.htm   (7126 words)

Food-junk and some mystery ailments: Fatigue, Alzheimer's, Colitis, Immunodeficiency. Carrageenan Carrageenan has been found to cause colitis and anaphylaxis in humans, but it is often present in baby “formulas” and a wide range of milk products, with the result that many people have come to believe that it was the milk-product that was responsible for their allergic symptoms. Carrageenan poisoning is one known cause of the disappearance of macrophages. Guar gum, pectin, carrageenan type I (80% kappa, 20% lambda), carra-geenan type II (iota) and cellulose were each fed at levels of 5 and 15% (wt/wt) of the diet for 31 d to male Fischer 344 rats. raypeat.com /articles/nutrition/carrageenan.shtml   (8915 words)

Carrageenan - Wikipedia, the free encyclopedia Carrageenans or carrageenins (pronounced [ˌkærəˈgiːnəns]) are a family of linear sulphated polysaccharides extracted from red seaweeds. Carrageenans are large, highly flexible molecules which curl forming helical structures. Poligeenan is produced from carrageenan under high temperature and acidity. en.wikipedia.org /wiki/Carrageenan   (687 words)

[No title] It is evident that since carrageenan is a large molecule being made up of some 1000 residues, the possibility for structural variations are enormous. Iota carrageenan is characterized by having 4-sulfate ester groups on all D-galactose residues and 2-sulfate ester groups on all 3.6-anhydro-D-galactose residues. As in the case of kappa carrageenan, iota carrageenan also shows irregularities in the form of 6-sulfate ester groups on some D-galactose residues and through alkali treatment the iota carrageenan becomes more regular. www.cpkelco.com /carrageenan/structure.html   (318 words)

VegSource Article Carrageenan appeared to enter the cells by membrane-associated endocytic vesicles and accumulate in endosomes and lysosomes. Cohen's attempt to distance himself from the true basis of Tobacman's suspicion of carrageenan while citing her as an authority is pathetic. Virtually all the bad news [about carrageenan] comes from rat studies, and one experiment suggests the bacteria that live in the rat intestine may contribute to the effects while bacteria from humans do not result in the same problems. www.vegsource.com /articles/silk3.htm   (3423 words)

934. Carrageenan (WHO Food Additives Series 42) Carrageenan did not affect the number or distribution of these cells; however, when antigen was administered systematically to carrageenan-fed rats, the antigen-specific antibody response was suppressed. Carrageenan caused a significant, dose-related decrease in the weights of offspring at weaning but had no effect on fertility, average litter size, average number of liveborn animals, or the viability or survival of offspring. The presence of carrageenans in the macrophages in the walls of the caecum and colon may reflect the relative molecular mass distribution of the preparation used in the study. www.inchem.org /documents/jecfa/jecmono/v042je08.htm   (8606 words)

Review of Harmful Gastrointestinal Effects of Carrageenan in Animal Experiments Degraded carrageenan in the diet of rats at a 10% concentration in association with exposure to 1,2-DMH weekly for 15 weeks was associated with an increase in small intestinal tumors from 20% to 50% and in colonic tumors from 45% to 60% (64). Indirect evidence relating exposure to carrageenan and the occurrence of ulcerative colitis and intestinal neoplasms consists of the similar geographic distribution between higher consumption of carrageenan and higher incidence of inflammatory bowel disease and colorectal cancer. The use of a viscosity measurement to characterize a carrageenan sample is insufficient because the presence of a small number of large molecules (and undegraded carrageenan may have molecular weight in the millions) may obscure a significant low molecular weight fraction. www.ehponline.org /members/2001/109p983-994tobacman/tobacman-full.html   (7404 words)
