摘要：

The properties of refined.-carrageenan (RC) extracted from red algae originated from Karimun Jawa Island has never been studied. The objective of this research was determining the effect of KCl on characteristic of refined.-carrageenan extracted from the red algae [Kappaphycus alvarezii (Doty ex P. C. Silva, 1996)]. The result indicated that higher KCl concentration resulted in the increase of the carrageenan yield, ash and sulphate content, and the decrease of gel strength, moisture and acidinsoluble ash content. The carrageenan viscosity demontrated a fluctuated value due to KCl concentration. This study suggested extraction process by using 2.5 % KCl solution. The carrageenan yield was 34.3 % and the result demonstrated the carrageenan properties as follow: 8.20 cP viscosity, 94.45 g . cm(-2) gel strength, 6.3 % moisture content, 59.4 % ash content, 1.78 % acidinsoluble ash, and 7.75 % sulphate content. The absrbance peak at 849 cm(-1) detected from infrared spectrscopy indicated Dgalactose-4-sulphate which is related with.-carrageenan. (C) 2016 The Authors. Published by Elsevier B.V.
