Optimization of Ultra-High Pressure Extraction Process of Polysaccharides from Dendrobium Candidum by Response Surface Method

Abstract:

Ultra-high pressure extraction technique was used to extract polysaccharides from Dendrobium candidum. Extraction pressure, pressure holding time and liquid-solid ratio were found to have a significant influence on the polysaccharides extraction and were optimized by the response surface method (RSM). The obtained optimum conditions were: extraction pressure 445.28MPa, pressure holding time 6.7 minutes and liquid-solid ratio 237.91ml/g. The maximum polysaccharide yield could reach 596.75mg/g under these conditions. The ultra-high pressure extraction process was a suitable method for its higher yield and shorter extraction time compared to the water-heating extraction.
