The objective of this research was to<br />investigate the possibility of Gracillaria used as nata raw material and to learn influence of sucrose<br />and ammonium sulphate concentration on quality of nata. Result indicated that the ratio of seaweed<br />and water generated the highest yield was 1:70 (w/v). The combination of sucrose and ammonium<br />sulphate concentration significantly influenced to yield, thickness, degree of whiteness, crude fiber,<br />dietary fiber of nata. Using sucrose was 7.5 %(w/v) and ammonium sulphate was 0.75 % produced<br />nata with the best characterization.<br />Key words: Gracillaria sp., nata</div&gt;}, number={2}, journal={Jurnal Pengolahan Hasil Perikanan Indonesia}, author={Purwaningsih, Sri and Salamah, Ella and Setiani, Apit}, year={1}, month={1} }
