Multinuclear n.m.r. studies of group I cations in furcellaran gels
International Journal of Biological Macromolecules, 1990Multinuclear n.m.r. experiments were carried out in order to study the possible selective interaction between group I cations and furcellaran. It has been shown that the intensity of the 39K, 87Rb and 133Cs spectra show a change in the vicinity of the sol-gel transition.

Molecular transforms of kappa carrageenan and furcellaran from mixed gel systems
International Journal of Biological Macromolecules, 1991X-ray fibre diffraction studies of furcellaran-carob, furcellaran-tara, and furcellaran-konjac mannan mixed gels have failed to reveal any evidence for the predicted intermolecular binding between the algal polysaccharide helix and the galactomannan or glucomannan (konjac) mannan).

Food / Nahrung, 1980
AbstractConsideration has been given to the creep of furcellaran gels concentrated to 0.5‐2.0% at temperatures of 25 to 50 °C in the region of linear viscoelasticity. The gel shear modulus (G) corresponding to reversible strain decreases with temperature. The dependence of the shear modulus on concentration at 25 C has the form G ∞ c2.7.

Furcellaran, a versatile seaweed extract
Economic Botany, 1959Introduction Up to recent times users of seaweed hydrocolloids have had their choice of only three types: carrageenan, algin, and agar. Now comparative newcomers have become increasingly important. One of the most promising of these is furcellaran, the extract of the seaweed species Furceliaria fastigiata (Fig. 1).

Albumin–furcellaran complexes as cores for nanoencapsulation
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2014The possibility of using protein–polysaccharide complexes as cores for nanocapsules formation by sequential adsorption of polyelectrolytes were investigated. We selected the globular protein bovine serum albumin (BSA) and the natural anionic polysaccharide–furcellaran (FUR) and studied their complexation in the broad range of their concentration ratio ...

ESTIMATION OF ALGINATE, CARRAGEENAN AND FURCELLARAN IN BEER
Journal of the Institute of Brewing, 1976Quantitative and semi-quantitative methods are given for estimating alginate, carrageenan and furcellaran at low concentrations in beer. A number of commercial beers and experimental beers known to have been brewed with either copper finings or auxiliary finings containing these acidic polysaccharides as active ingredients were analysed for alginate ...

Structural aspects of phase separation in the furcellaran—water system
Carbohydrate Research, 1990The structure and gel-forming properties of the furcellaran-water system is investigated. Experimental data indicate that gelation in the furcellaran-water system is associated with micro-crystallization of polysaccharide macromolecules and that, under conditions of phase separation, the system itself is a system with incomplete crystallization ...

Red Seaweed Extracts (Agar, Carrageenans, Furcellaran)
2022In Japan, the agar-bearing seaweeds are gathered from rocks between mid- and low-tide marks, or else divers collect them from the sublittoral regions. For centuries, agar was produced by simply boiling seaweeds to obtain a gelatinous mass. The modern methods of preparation and purification was discovered by accident.

Enzyme-Assisted Preparation of Furcellaran-Like κ-/β-Carrageenan
Marine Biotechnology, 2015Carrageenans are sulfated galactans that are widely used in industrial applications for their thickening and gelling properties, which vary according to the amount and distribution of ester sulfate groups along the galactan backbone. To determine and direct the sulfation of κ-carrageenan moieties, we purified an endo-κ-carrageenan sulfatase (Q15XH1 ...
