“…All absorption bands of the FTIR spectra (Table ) show that carrageenan from the three Indonesian coastal areas are found to be iota‐carrageenan. Such finding is in agreement with the work showing kappa and iota‐carrageenan, which can be distinguished from all other carbohydrates because of the absorption band at 848 cm −1 region as the D‐galactose‐4‐sulfate, while the strong band at 806 cm −1 is D‐galactose‐2‐sulfate (Deslandes et al ; Chopin & Whalen ).…”

Carrageenan extracted from Eucheuma spinosum harvested from three different coastal sea regions, where this alga has been mainly cultivated, were determined for their chemical and physical characteristics. The carrageenan was extracted from the seaweed using hot alkali followed by precipitation, drying, and milling. The carrageenan properties were determined in terms of yield, ash, mineral, sulfate content, functional group, molecular weight, and viscosity profile. Physical characteristics of carrageenan were evaluated by a texture analyzer for gel strength and a rapid visco analyzer for viscosity.The yield of carrageenan from Sumenep (34.81 AE 5.83%) and Takalar (37.16 AE 3.26%) was found to be relatively higher than that of Nusa Penida (25.81 AE 1.93%). The calcium content was higher than magnesium, potassium and sodium content, and no cadmium, lead, mercury, and arsenic detected in all carrageenan. The ash content was around 29%; while, the sulfate content was in the range of 30-32%, and those were not different in all carrageenan. The presence of sulfate content was identified by FTIR at absorption band of 1373 cm −1 . It was found that the molecular weight of carrageenan from Takalar were relatively higher and the gel strength of carrageenan from Takalar were significantly higher than that of carrageenan from Nusa Penida and Sumenep. Likewise, upon cooling from 80 to 20 C, the viscosity profile of carrageenan from Takalar characterized by higher viscosity compared to that of carrageenan from Sumenep and Nusa Penida. These results indicated that carrageenan from Nusa Penida, Sumenep, and Takalar were identified as iota-carrageenan with similar physico-chemical characteristics except for the gel strength, viscosity profile upon cooling from 80 to 20 C and the yield.

“…Species belonging to the Kallymeniaceae present a heterogeneous phycocolloid composition indicative of a need for taxonomic re‐examination: Beringia castanea Perestenko and Velatocarpus pustulosus (Postels et Ruprecht) Perestenko, sometimes placed in the family Crossocarpaceae, are agar producers (Usov and Klochkova 1992); Callophyllis cristata and Cirrulicarpus gmelini produce polysaccharides in between agar and carrageenans (Usov and Klochkova 1992); Callophyllis rangiferina (Turner) Womersley produces carragars (this study); Callophyllis rhynchocarpa Ruprecht and Erythrophyllum sp. produce carrageenans (McCandless 1978; Usov et al 1983); Callophyllis variegata (Bory) Kützing, Kallymenia reniformis (Turner) J. Agardh and K. westii Ganesan produce λ‐type carrageenans (this study, Deslandes et al 1990; Chopin et al 1994) and K. limminghii Montagne produces κ‐/ι‐/μ‐carrageenan hybrids (this study).…”

The taxonomic significance of the polysaccharide structures of algal cell walls has been underscored several times over the past few decades but has never been pursued systematically. Many changes in red algal systematics and the biochemical analyses of phycocolloids have occured in recent years. The cell‐wall composi‐tion of representatives of 167 (24.7%) genera and 470 (11.5%) species of red algae has been documented.The method developed by Chopin and Whalen for carrageenan identification by Fourier transform infrared diffuse reflectance spectroscopy is extended to the study of phycocolloids for diverse species in many red algal orders. This paper focuses on the Gigartinales in which representatives of 28 (68.3%) families, 88 (50.6%) genera and 224 (27.9%) species have been analyzed. In light of recent molecular phylogenies, some patterns of distribution of key phycocolloid attributes, corresponding to familial and ordinal level groupings, are emerging; however, more species remain to be analyzed. The well‐documented biochemical alternation of generations in the Phyllophoraceae, Petrocelidaceae and Gigartinaceae still holds (with two exceptions), but this pattern was not recorded in other families of Gigartinales.

“…By combining 13 C-NMR with FTIR, the carrageenan nature can be established [8]. Solutions of l-carrageenan and its variants are extremely viscous; hence it has not been possible to get a good NMR spectrum in liquid phase studies [9].…”

Many seaweeds produce phycocolloids, stored in the cell wall. Members of the Rhodophyceae produce polysaccharides the main components of which are galactose (galactans)-agar and carrageenan. In addition, alginic acid is extracted from members of the Phaeophyceae. This is a binary polyuronide made up of mannuronic acid and guluronic acid. The wide uses of these phycocolloids are based on their gelling, viscosifying and emulsifying properties, which generate an increasing commercial and scientific interest. In this work, the FTIR and FT-RAMAN spectra of carrageenan and agar, obtained by alkaline extraction from different seaweeds (e.g. Mastocarpus stellatus, Chondrus crispus, Calliblepharis jubata, Chondracanthus acicularis, Chondracanthus teedei and Gracilaria gracilis), were recorded in order to identify the type of phycocolloid produced. The spectra of commercial carrageenan, alginic acid and agar samples (SIGMA and TAAB laboratories) were used as references. Special emphasis was given to the 500-1500 cm(-1) region, which presents several vibrational modes, sensitive to the type of polysaccharide and to the type of glycosidic linkage. The FT-Raman spectra present a higher resolution than FTIR spectra, this allowing the identification of a larger number of characteristic bands. In some cases, phycocolloids can be identified by FT-Raman spectroscopy alone.
