Consequently, the greater magnitude of elongation at break is characterized by gelatin capsule shells in comparison with capsule shells based on carrageenan.
It has been shown that the higher magnitude of load at break and elongation at break are characterized by gelatin capsule shells as compared with capsule shells based on carrageenan.
Traditionally refined carrageenan is produced by extracting it from the seaweed and filtering the extract to remove cellulose and other substances.
Joanne Tobacman, a researcher at the University of Illinois at Chicago College of Medicine, published a safety review of carrageenan in Environmental Heath Perspectives.
New production technologies recently developed by Cargill not only allow the company to use alternative and more secure raw material sources for its carrageenans
, but also enable improved functionality of the seaweed extracts.
Fitting the Response Surface Models The effect of three independent variables, CMC-Na content, xanthan gum content and carrageenan
content, on two response variables (viscosity and cloudiness) was evaluated by using the response surface methodology (RSM).
Colorimetric determination of carrageenans
and other anionic hydrocolloids with methylene blue, Analytical chemistry, 66: 4514 - 4521.
From about 15 principal structure types of carrageenans
, two galactans, called kappa and iota carrageenan
A novel biopolymer-based superabsorbent hydrogel,kC-g-poly(AA-co-NIPAM)was used Hydrogel was synthesized through simultaneous crosslinking and graft polymerization of acrylic acid/N-isopropylacrylamide mixtures onto kappa- carrageenan
In rodent models, there is clear evidence that degraded carrageenan
can induce ulcerations and neoplasms.
Twenty-five percent of total carrageenans
in eight food-grade carrageenans
were found to have molecular weight < 100,000, with 9% having molecular weight < 50,000 (9).
Previously, the JECFA considered modification of their recommendation about carrageenan
to include a minimum average molecular weight (3,4).
