Abstract Caulerpa racemosa grain was a healthy product and high nutrition. This study applied study was applied Caulerpa racemosa grain in the beverage with the addition of alginate powder. Thus, the present work was aimed to determine the properties of beverage C. racemosa grain formulated with the alginate concentration was varied (0; 0.025; 0.05; 0.075; 0.10 and 0.125 %). The testing of quality beverage C. racemosa viscosity was analyzed using viscometer methods. The colorimeter investigated the colour. The sensory acceptability hedonic and score method (colour, appearance, aroma, taste, texture, and overall acceptance) used a 5-point. Results showed that alginate used alginate 0.025%, the highest preference, aroma, and appearance scores. The addition of alginate increased alginate was increased the viscosity of beverage C. racemosa grain. The colour of C. racemosa grain progressively became light as the level of alginate grew. However, the increased alginate is not significant enough to change the redness and greenness value of C. racemosa grain beverage. The panelists have preferred to drink the selected Caulerpa grain beverage (concentration sodium alginate 0.025%), with slightly viscous.

Alginate-diatomite immobilized microspheres were prepared through immobilized biosorption of diatomite and Aspergillus niger by sodium alginate. Three major factors such as alginate concentration, diatomite content and embedding capacity on physical properties and microbial activity of Alginate-diatomite immobilized microspheres were investigated, and the optimal preparation conditions of Alginate-diatomite immobilized microspheres were determined as 2% of alginate, 1% of diatomite, 10% of Embedding capacity.

Dope Concentration

Alginate fibers were prepared by extruding a concentrated sodium alginate solution into calcium chloride coagulation bath. The rheological behavior of different concentrations of sodium alginate solutions were investigated to evaluate the spinnability. The effect of dope concentration on the morphologies and mechanical properties of resulting alginate fibers were examined. The results showed that sodium alginate solutions were pseudoplastic fluid and had good spinnability with concentration ranging in 1.5%-3.5%. Moreover, the morphology of obtained fibers became smoother with increasing sodium alginate concentrations. When the sodium alginate concentration was 3.5%, the tensile strength and elongation at break of alginate fibers reach to 13.6±1.2 cN/tex and 8±0.5%, respectively.

Physical Crosslinking

To mimic the alveolar bone and periodontal ligament interface, a chitosan(CS for short) composite polysaccharide scaffold was fabricated which was cross-linked with sodium alginate(SA for short). The conditions of physical crosslinking in the scaffolds were discussed. By characterization after biomineralization, it turns out that pH=5.0 and 40min crosslinking time can make for crosslinking. Better crosslinking makes the material more antiswelling and give more compressive strength. In the other hand, the biomineralization can improve the physical properties of the material. We hope that after further research it can come to a scaffold material with good properties.

Preliminary Study

Utilization of brown algae especially in Madura, where it’s close to Surabaya, only limited for food. This become a reference for developing and increasing the potential of this algae by extracting one of the ingredients, namely alginate. This paper deals with the characterization of sodium alginate extracted from sargassum sp. using modified-purified calcium routes. The extracted sodium alginate will be further used as composite hydrogel materials and compared with commercial sodium alginate. Hereafter, the synthesized composite is expected to be bio-ink for 3d printer. Chemical composition analysis were analyzed using X-Ray Fluorosense (XRF) followed by Fourier-transform infrared spectroscopy (FTIR) analysis to identify the functional group of composite and X-Ray Diffraction (XRD). Furthermore, viscosity bath is performed to compare the viscosity of extracted and commercial one. The result shows that modified-purified calcium routes in the extraction process of sodium alginate is desirable for improving their properties. Interestingly enough, with the goal of using it as bio-ink in 3d printed fabrication, the synthesized composite shows viscosity, 300 cSt, which meets the criteria for bio-ink in 3d printer.
