of Semi Refined Carageenan (SRC) which extracted from Kappaphycus alvarezii.
The production of SRC was conducted by alkali treatment of seaweed and to obtain
the powder used spray drying technique. This analysis based on two independent
parameter which are concentration of potassium hydroxide (KOH) and extraction
time. Extraction temperature during alkali treatment process was fixed as constant
which was 70-80°C. The optimization of extraction process parameters and
the experimental design were done based on Central Composite Design (CCD) of
Response Surface Methodology (RSM). Gel viscosity, powder weight of SRC, particle
size and gel strength were studied as responses. The bounds of all these factors
keyed in the RSM to get the predicted number of experiments. Optimum process
extractions for spray drying technique result showed at 6.70% of KOH concentration
and 74.70 minute extraction time. At optimum conditions the viscosity of the
SRC gel was found as 111.80 cP and the particle size of SRC powder was found
as 86.88 μm. Gel strength was optimize at 85.60 g cm-2 and SRC
powder production as 5.01 g.]]>Bono, A., S.M. Anisuzzaman and O.W. Ding,2012Kappaphycus alvarezii).]]>2012Bono, A., K. Krishnaiah and M. Rajin,2008Bono, A., Y.Y. Farm, S.M. Yasir, B. Arifin and M.N.
