Abstract


Sago waste liquid is the waste product in sago processing. It can be used as nata de sago raw material. The starch in sago waste liquid is used by Acetobacter xylinum to form polysaccharides layer during fermentation process. This result aimed to study the quality of nata de sago from sago waste liquid. This was a descriptive study with five replications. Each plate was contained 500 mL medium, 80 mL Acetobacter xylinum starter, and 14 days fermentation period. Nata de sago quality was measured by color, aroma, elasticity, gross weight, dry weight, residual volume, sulfate residue, and sucrose level. The results then compared with SNI 01-4317:1996. The result shows that the color of nata de sago is white-gray (scale 7) with the sourish aroma and rather chewy. The gross weight is 176,60 g, dry weight is 2,40 g, the residual volume is 48,20 mL, percentage of sucrose is 0,627%. The result also found that the nata contain sulfate residual positively. Aroma and elasticity was matched with SNI 01-4317:1996.
