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.…”

“…The difference in viscosity value indicates the occurrence of degradation at the time of alginate extraction. The presence of degradation causes a decrease in the weight of the alginate molecule so that the viscosity of the alginate also decreases [5,6]. In addition, the precipitation process with ethanol solution according to Jian et al [49].…”

“…The resulting pH in the study ranged from 6.57-9.72. In the research of Hamrun and Rachman [39]; Herlina et al, [42]; Hamrun et al, [5,6]; Viswanathan and Nallamuthu [43]; and Mushollaeni [46] the results of the pH parameters were not reported. In the literature reported, the pH parameter is in accordance with the quality standard of alginate quality based on the Food Chemical Codex (FCC) which is 3.5-10.…”

“…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).…”
