Alginate Extraction

Seaweed is one of the marine biological resources of Indonesia that has a high potential to produce alginate, however, the most appropiate method to extract the alginate of high quality is still unknown. This study was aimed to determine the effects of extraction methods on the quality of alginate from seaweed Sargassum hystrix and compared the extraction cost. Two extraction methods were used in this study including acidic and calcium method. The yield, moisture content, viscosity, pH, whiteness degree, functional group, ash content and extraction cost were evaluated. The viscosity and whiteness degree of sodium alginate from acidic method was 126.00±7.21 cPs and 75.27±0.58 cPs, respectively. Meanwhile the calcium method produced sodium alginate with viscosity 7.23±1.50 cPs and whiteness degree 68.95±0.18 cPs. The yield, moisture content, and ash content of alginate produced by acidic method were lower compare to that of produced by calcium method. Cost analysis showed the acidic method required higher cost. Nevertheless, these resultssuggest that acidic method produce alginate with better quality than the calcium method.

ABSTRAK: Padina sp. merupakan spesies rumput laut cokelat (Phaeophyta) penghasil alginat, namun kualitas alginat yang dihasilkan tergolong rendah dibandingkan alginofit lainnya. Metode ekstraksi jalur kalsium diduga dapat meningkatkan kualitas alginat sehingga penelitian ini perlu dilakukan. Tujuan penelitian ini untuk mengkaji apakah ekstraksi jalur kalsium dapat meningkatkan mutu alginat yang dihasilkan dari rumput laut Padina. Ekstraksi dilakukan dengan metode jalur kalsium konvensional dan jalur kalsium MAE (Microvawe Assisted Extraction). Metode penelitian yang digunakan adalah eksperimental laboratoris dengan 1 perlakuan (kosentrasi CaCl2) dan 3 taraf konsentrasi yaitu 0,5 M 1,0 M dan 1,5 M. Parameter kualitas yang dianalisis meliputi rendemen, kadar air, Kadar abu, viskositas, pH dan FTIR. Hasil uji two way ANOVA menunjukan terdapat signifikansi rendemen dengan nilai 0,007. Metode jalur kalsium MAE dengan konsentrasi 1,0 M CaCl2 menghasilkan kualitas terbaik dengan nilai rendemen (26,83%), kadar air (10,67%), kadar abu (21,83%), viskositas (11,42 cPs)  dan pH (6,77). Hasil analisis FTIR menunjukan ke-2 metode ekstraksi menghasilkan natrium alginat dengan adanya sidik jari guluronat dan manuronat pada bilangan gelombang 930-890 cm-1 dan 870-820 cm-1. ABSTRACT: Padina sp. is a species of brown seaweed (Phaephyta) producing alginates, but the quality of alginates produced is relatively low compared to other alginophytes. The calcium pathway extraction method is thought to improve the quality of alginates thus the reason of the research. This research aims to examine whether the calcium pathway extraction improves the quality of alginates produced from Padina. Seaweed extraction was carried out using conventional calcium pathways and MAE (Microwave Assisted Extraction) calcium pathways. The research method used was laboratory experimental with 1 treatment (CaCl2 concentration) and 3 concentration levels : 0.5 M, 1.0 M, 1.5 M. Quality parameters analyzed includes yield, moisture content, ash contetnt, viscosity, pH and FTIR. The two way ANOVA test results showed that there was a significance of yield value of 0.007. The MAE calcium pathway method with a concentration of 1.0 M CaCl2 produces the best quality with a yield value (26.83%), water content (10.67%), ash content (21.83%), viscosity (11.42 cPs) and pH (6.77). FTIR analysis results show that the two extraction methods produces sodium alginate in the presence of guluronate and manuronic fingerprints at wave numbers 930-890 cm-1 and 870-820 cm-1.

Hydrolysis Of

Sodium alginate, a brown seaweed polysaccharide, is capable of preventing intestinal absorption of radioactive strontium and its radiotoxicological importance is now well established. Alginic acid was found to be composed of 1,4-linked poly-L-guluronic acid and poly-D-mannuronic acid chains with some glycosidic linkages between these uronic acids.Polyguluronic and polymannuronic acid were prepared by acid hydrolysis of alginic acid from Laminaria hyperborea followed by fractionation of the partially degraded sodium alginate at pH 2.8. These components consist almost exclusively of a single uronic acid (polyguluronic acid: man/gul = 0.27; polymannuronic acid: man/gul = 10.7). Sodium polyguluronate inhibits absorption of radiostrontium more effectively than sodium polymannuronate.

AbstractAlginates are natural polysaccharides that are extracted from brown seaweed varieties and it is widely used for their rheological properties. The main step in the extraction protocol of sodium alginate is alkaline extraction. Sodium alginate was produced by dipping the seaweed in 1% formaldehyde and 2.5% of sodium carbonate solution and properties were studied following the standard methods. The amount of sodium alginate yield was 31.7% in Sargassum wightii. The moisture content and the ash content were recorded at 16.82% and 5.20%, respectively. The viscosity and the gel strength were noted as 40 vcP, 4.54 × 10–2 kN with 0.1 M CaCl2 and 6.86 × 10–2 kN with 0.2 M CaCl2 respectively. This study of the extraction method and its properties reveal that Sargassum wightii brown seaweed species have a high affinity to extract the alginate.

Indonesia has a lot of high potential seaweed as a source of an alginate, but the extraction method had been used was not suitable. The aim of this research is to develop alginate extraction method from Turbinaria ornata seaweed with calcium method and compare the cost of extraction with an acid method as a control. In this research, various concentration of calcium chloride (CaCl2) was used in the separation of alginate from the extracted filtrate. The concentration of CaCl2 used varies from 0.50; 0.75; 1.00; 1.25; and 1.50 M. For comparison, alginate extraction with acid (control) method was used. Alginate quality parameters observed included alginate yield, product color degree, and gel viscosity. The results showed that the yield of alginate produced by calcium method was 36.89; 44.00; 56.00; 52.89 and 53.11% and for control 22.45%. From the degree of product color, CaCl2 concentration did not significantly affect the color of alginate but was darker when compared to the product extracted by the acid method. The viscosity of alginate produced by calcium method was 27,69; 26,57; 24.50; 22.41 and 19.92 cP while for control 32.88 cP. The extraction of Na-alginate with calcium method can decrease the need for Na-alginate extraction cost by 85% from the amount of  Na-alginate extraction cost requirement by the acid method.
