The critical sequence length for kappa-sequences is 2-fold of that for iota-sequences. Gino is the (Kappa & Iota) carrageenan supplier and exporter in China, our products are all certified by HALAL, KOSHER and all from GMP & HACCP certified. Intrinsic thermodynamic properties (e.g., transition temperature and enthalpy) of kappa- and iota-sequences in these copolymers are close to those of their parent homopolymers. With respect to the ordering capability, the kappa/iota-hybrid carrageenans seem to behave as random block copolymers with length sequence distributions truncated from the side of the small lengths.

High-sensitivity DSC showed that the total transition enthalpy of the kappa/iota-hybrids goes through a minimum at 60 mol-% kappa-units, whereas for the mixture of kappa- and iota-carrageenan, the total transition enthalpy is a linear function of the composition. ![]() The conformational order-disorder transition of the kappa/iota-hybrids was studied using optical rotation and high-sensitivity differential scanning calorimetry. There are three types of carrageenan that are most widely used: Kappa, iota, and lambda. One of nature’s perfect stabilizers and thickeners, carrageenan is used to improve the texture, taste, and appearance of many foods. This allows one to control the gel strength independent of the gelation or melting temperature. It is made from red seaweed that is sustainably grown and harvested by family farmers from oceans around the world. On the other hand, the gelation temperature of the kappa-rich kappa/iota-hybrids is independent of their composition. The gel strength (storage modulus, G') of the kappa/iota-hybrids decreases with decreasing kappa-content. Their rheological properties were determined by small deformation oscillatory rheology. The kappa/iota-ratio of these kappa/iota-hybrids was determined by NMR spectroscopy. To this end, a series of kappa/iota-hybrid carrageenans ranging from almost homopolymeric kappa-carrageenan (98 mol-% kappa-units) to almost homopolymeric-carrageenan (99 mol-% iota-units) have been extracted from selected species of marine red algae (Rhodophyta).
