“…This is because the acidic solvent utilised in the extraction techniques draws out fucoidan and gets rid of alginates. Even though alginic acid is still present in the extract (Sinurat and Kusumawati 2017). When compared to HW and EDTA extraction techniques, fucoidan from different samples extracted using the HA extraction technique contains the least quantity of sugar.…”

In brown seaweeds, cell wall polysaccharides are dissolved in hot water, acid, and organic solvents to extract fucoidan. The study looked at 13 Indian brown seaweeds and used three different fucoidan extraction techniques: hot water (HW), hydrochloric acid (HA), and ethylenediaminetetraacetic acid (EDTA). The yield of the HA extraction technique was higher than that of the EDTA and HW extraction techniques. When compared to the EDTA and HA extraction techniques, the HW extraction technique showed the highest fucose and sulfate content. Furthermore, the EDTA extraction technique revealed the highest protein content compared to the HA and HW extraction techniques. Among different fucoidan samples from various extraction techniques, S. cinctum had a high fucose and sulfate content. Therefore, we evaluated S. cinctum using different extraction techniques for FTIR analysis. The absorption areas near 1270 cm-1, 1030 cm-1 and 870 cm-1 in the HW, HA, and EDTA extraction techniques of S. cinctum indicate the presence of sulfate groups. After examining the different fucoidan extraction techniques, the HW extraction technique was shown to be the most effective and ecologically friendly method for the extraction of fucoidan. Studying the effects of different extraction techniques benefits a variety of industries, including the cosmetics, nutraceutical, and pharmaceutical industries.

“…The distilled water solvent that is varied at high temperatures only plays a role as a breaker of interactions between fucoidan and cell walls; thus, alginate and other polysaccharides found in cell walls are also potentially extracted. Meanwhile, the 2% CaCl2 solvent plays a role in separating fucoidan from alginate so that the resulting fucoidan content is higher [24].…”

Seaweed is one of the highly commercial aquatic commodities, accounting for 51.3% of total marine and coastal aquaculture production. As much as 99.5% of seaweed production is concentrated in Asia, especially in East and Southeast Asian countries, one of which is Indonesia. The wide diversity of seaweeds has not been fully optimizing their potential to provide maximum economic benefits. This study aimed to determine the characteristics of crude extracts of fucoidan using two different solvents and to analyze the antioxidant activity of crude extracts of fucoidan using different solvents. The research method included the preparation of raw materials, extraction with distilled water and 2% CaCl2 at 85 °C for 4 h, followed by quality analyses. Total sugar using the phenol-sulphate method obtained higher results in distilled water (67.88%). The total sulphate analysis showed higher results with 2% CaCl2 (19.60%). The total phenol analysis yielded higher results with 2% CaCl2 (978.20%). The antioxidant activity of the crude fucoidan were 312.01 ppm (distilled water), 193.52 ppm (distilled water), 54.653 μg/mL ascorbic acid/g extract (CaCl2 2%, 128.38 mol Fe2+/g (CaCl2 2%).

“…However, the obtained results inversely correlated with the theory because the addition of a higher amount of sodium phosphate powder shortened the setting time. The combination of calcium salt and sodium alginate with water produces a water-insoluble elastic gel known as calcium alginate [11]. The chemical reaction is as follows [7]:…”

This study was aimed to prepare dental impression material from Sargassum duplicatum taken from Binuangeun, Banten. The setting time was tested according to ANSI/ADA Specification for Alginate Impression Materials 1983. After extraction, obtained the alginate powder then mixed its water/powder ratio from the combination of alginate composition and tested final setting time. Variations of the formulations used different calcium sulfate (0,1 g; 0,2 g; and 0,3 g). Product quality parameters are lumps, solubility, consistency, flow, tearing, setting time. The alginate yield obtained from Sargassum duplicatum by 31 % with characteristic gel strength by 816 (gr/cm 2 ); viscosity 238 mPas (2%; room temperature). The highest ratio is the best ratio by adding calcium sulfate powder of 0.1 gram with a setting time of 3 minutes.
