合成制备方法

各种植物的块根干燥后经去皮、切片、烘干、粉碎、过筛所得细粉，称“魔芋粉”，得率约60%～80%。由β-1，4糖苷键联接的D-吡喃葡萄糖和D-吡喃甘露糖，占干物质总量70%～80%，颗粒直径0.15mm左右，由于颗粒表面覆盖有非葡甘聚糖，影响吸水性，凝胶能力低。
为此，可用乙醇、石油醚等进行物理改性，以提高水溶性、溶解粘度、溶解速度等性能，为此可将块根切片、粉碎后浸于乙醇中，在60℃下减压干燥，用石油醚脱脂，加氢氧化钠液溶解后过滤，滤液用盐酸中和后再加醋酸铅提取，取滤液，通入硫化氢以除去铅离子，加乙醇沉淀，离心分离后用丙酮干燥，先为粗品，再用氢氧化钠溶解，过滤，用盐酸中和后浓缩，用乙醇沉淀，离心后再用丙酮干燥而得精品，称“魔芋精粉”。

用途

胶凝剂;增稠剂;乳化剂;稳定剂;成膜剂。
