Abstract:
The objective for this work was to study the characteristics 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.
