The Influence of Sucrose and Amonium Sulphate Concentration on Quality of Nata Gracillaria sp.
Abstract
Nata is biomass that mostly consist of cellulose, physically resemble to agar with white layer.
In this research nata was made from seaweed that is Gracillaria sp. as a raw material, because of the
cheap price of this seaweed and it content of high fiber. The objective of this research was to
investigate the possibility of Gracillaria used as nata raw material and to learn influence of sucrose
and ammonium sulphate concentration on quality of nata. Result indicated that the ratio of seaweed
and water generated the highest yield was 1:70 (w/v). The combination of sucrose and ammonium
sulphate concentration significantly influenced to yield, thickness, degree of whiteness, crude fiber,
dietary fiber of nata. Using sucrose was 7.5 %(w/v) and ammonium sulphate was 0.75 % produced
nata with the best characterization.
Key words: Gracillaria sp., nata
