Extraction of Pectin from Sisal Residue
摘要
Abstract
The method of pectin extraction from sisal residue was optimized by orthogonal experiments, and pectin separation and decoloration were also studied. The optimized extraction conditions were as follows ; 2. 2 mol ? L"' oxalic acid-ammonium oxalate buffer as extracting agent, the solid to liquid ratio 0. 1 g ? mL"', time 90 min, temperature 80 t. Pectin was precipitated by alcohol at pH 4. 0; the yield of sisal pectin was 14. 87%. The primrose yellow pectin was decolored by 1. 8% -2.4% H2O2. The results of physicochemical property were that the degree of esterification of sisal pectin was 23% , galactu-ronic acid 66% , pH and ash all complying with Chinese light industey standards.关键词
