Abstract

Spirulina is a microalgae fine plant (Cyanobacteria) single celled, blue green colored, spiral typed growed in warmwater around the world. Spirulina have many Phytonutrient (Beta-carotene, Chlorophyl, Xanthophyl, Phyocianin, etc)functioned as anti-carcinogen (Tri Panji & Suharyanto, 2001). Drying process usually use high cost drying tools(freeze dryer, spray dryer, roller dryer, or dehumidifier). Drying with the foam type faster the water evaporationprocess in a low temperature that is not destroyed the cell system, so the nutrition value is save (Kumalaningsih, etc,2005). In general, this research done to compare two drying method, there are: non foam-mat drying method and withfoam-mat drying method that show the optimum drying process condition to get the high quality of spirulina dryingproduct and the high efficiency process too. The result of the research show that the foam-mat drying method give thebetter drying rate compared with non foam-mat drying process. The sample with the foam agent composition (eggwhite) 2,5% and the foam stabilizer (metil celulose) 0,5% give the highest drying rate compare with the others. Thehighest average rate showed the sample with the thickness 1mm, which is 0,632 g H2O steamed per second.. Based onconsideration of product quality and drying process efficiency, drying temperature is relatively good to the applicationof foam-mat drying in spirulina is 60oC. The result of beta-carotene test show that the quality of dry product with foammatdrying method still on the dry product quality standard in the market, that is 149,025 mg/ 100 g. The data obtainedfrom the research be expected become the reference in the equipment design of the spirulina drying process andbecome the solution of cheap, efficient, and effective drying method, without decrease the nutrition value of thematerial.
