Abstract
The methods of the present invention prepare carrageenan products from processed seaweed material having a solids content of less than 25% by weight solids, using shear stress treatment. The carrageenan products comprise at least about 60% by weight of carrageenan and at least about 2% by weight of acid insoluble material. The carrageenan products of the present invention are useful as components in food products, such as, dairy products, meats, and dessert gels as well as non-food products, such as, toothpaste formulations, cosmetics, paints, films and delivery capsules.
Claims17
A method comprising:
- subjecting a carrageenan-containing seaweed material having a solids content of less than 25% by weight to a shear stress treatment to provide a carrageenan-containing product;
- providing a solution containing-the carrageenan containing product;
- forming a barrier material from the solution.
A capsule comprising a carrageenan material prepared by subjecting a carrageenan-containing seaweed material having a solids content of less than 25% by weight to a shear stress treatment.
A capsule comprising a film, wherein said film comprises a carrageenan material comprising at least about 60% by weight carrageenan and at least about 2% by weight of acid insoluble material and, optionally, at least one plasticizer, filler, binder, colorant, or flavorant.
A film composition comprising a carrageenan material comprising at least about 60% by weight carrageenan and at least about 2% by weight of acid insoluble material and, optionally, at least one plasticizer, filler, binder, colorant, or flavorant.
A semi-refined carrageenan product comprising at least about 60% by weight carrageenan and at least about 2% acid insoluble material.
