title: Modeling of polysaccharide extraction from Gossypium arboreum L. seed using central composite rotatable design.
abstract: The present study investigates the effect of independent variables such as extraction temperature (35-55 °C), time (1-5h) and solid-liquid ratio (1:5-1:25 g/ml) over the extraction yield of polysaccharide from Gossypium arboreum L. seeds was investigated and optimized. Aqueous extraction method was opted for the extraction of polysaccharide. Central composite response surface design was utilized for developing the experimental design. A second order polynomial mathematical model was developed from the obtained results. From the results, Significance of process variables over the extraction process can be clearly depicted. At the extraction temperature of 45 °C, extraction time of 3h and solid-liquid ratio of 1:15 g/ml maximum yield of polysaccharide (8.67%) from Gossypium arboreum L. seed was obtained. Characteristics of the extracted polysaccharide are analyzed through physico-chemical property analysis and Fourier Transform Infrared Spectroscopy (FTIR).
