Physical characteristics test (water content and viscosity) of extraction sodium alginate brown algae (phaeophyta) species padina sp. as basic material for production dental impression material

Abstract

Objective: This research aims to explore the potential of brown algae species padina sp. as a dental impression material by examining the physical characteristics of the sodium alginate extraction of brown algae species padina sp. Material and Methods:This research is a quasi-experimental with one-shot case study design. Samples are brown algae species padina sp. from Punaga and Puntondo beach in South Sulawesi. Brown algae species padina sp. is extracted to obtain sodium alginate and further tested for physical characteristics including viscosity test and water content. Results:The extraction of brown algae species padina sp. resulted in 250 grams (25%) of brown powdered sodium alginate that smelled fishy. Physical characteristic tests revealed the water content of sodium alginate species from brown algae padina sp. was 8%. This result is acceptable for sodium alginate water content as set by the Food Chemical Codex that requires less than 15% water content. The measurement of the viscosity obtained is 13.33 cps. Conclusion:These results indicate that the species of brown algae padina sp. has the potential to be one of the basic materials of dental impression material.

Isolation and partial characterization of alginate extracted from Sargassum polycystum collected from three habitats in Banten, Indonesia

“…Seaweed with a long thallus length will produce Na alginate with low viscosity, whereas if used with seaweed with a short thallus (20-40) cm it will produce high viscosity. Possible differences in the location where it grows is one of the causes of the difference in the value of the resulting viscosity (Hamrun 2018). The results of the alginate viscosity extracted from Sargassum polycystum are presented in Figure 9.…”

Effect of Extraction Method from Brown Seaweeds Padina sp. on Quality of Alginate for Edible Film Application: A Review

“…The water content of the alginate produced from the research of Viswanathan and Nallamuthu [43] does not meet the quality standard of alginate quality which refers to the Food Chemical Codex (FCC) which is <15%. In the research of Hamrun and Rachman [39]; Herlina et al, [42]; Hamrun et al, [5,6]; and Kautsari and Ahdiansyah (2018) the percentage of water content is not reported. The high and low water content is influenced by the process of soaking the alginate with a solution during the extraction process.…”

“…In the ash content parameter, the results ranged from 17.34%-31.24%. In the research of Hamrun and Rachman [39]; Herlina et al, (2016); Hamrun et al, [5,6]; and Kautsari and Ahdiansyah [47] the resulting ash content is not reported. The value of ash content is influenced by the washing process after the alginic acid formation process until the pH is close to a neutral number.…”

“…Padina sp. can be extracted and the seaweed extraction results produce alginate [5,6]. Alginate is a type of polysaccharide that makes up the cell wall components of brown algae (Phaeophyta).…”

The effect of extraction time on the quality of brown seaweed Na-Alginate Sargassum polycisteum as the base material for SBK Edible Film

“…Indonesia is one of the countries with the longest and widest coastal area in the world and a country with abundant natural resources. One of Indonesia's leading commodities is seaweed [1]. The wealth of seaweed in Indonesia is about 769,452 ha.…”
