Ammonium Oxalate Extraction and Analysis of Physicochemical Property of Pectin from Wax Gourd Peel
The aim of this paper was to explore the extraction of pectin with ammonium oxalate from wax gourd peel. Ammonium oxalate extraction process was optimized by orthogonal array design on the basis of a series of single-factor experiments, and physicochemical property of pectin from wax gourd peel were determined. Under the conditions studied,ammonium oxalate concentration,temperature, extraction time and material-to-liquid ratio could affect pectin extraction differently. And the optimal conditions of the four parameters were 1.5%, 80℃,2.0 h,and 1:30 (g/mL) respectively. Under these conditions,the extraction rate of pectin reached up to 8.91%. Furthermore,the quality indicators of the extracted pectin could meet the requirements of the govern-ment standard(GB25533-2010) and the industrial standard(QB 2484-2000).
