- 背景資料
葡甘露聚糖是由甘露糖和葡萄糖以β-(1,4)醣苷鍵鍵結而成的線性多醣,根據植物來源的不同,其甘露糖和葡萄糖的比例也會有所差異。
蒟蒻又稱魔芋(Konjac),其球莖為可供食品使用之原料,球莖中約含有50-60%葡甘露聚糖,一般被稱為蒟蒻葡甘露聚糖(konjac glucomannan ,簡稱KGM),甘露糖和葡萄糖的比例約為1.5:1,且KGM皆有乙醯基團(Acetyl,簡寫為Ac-)的連接,隨著乙醯化程度增加,則會導致KGM的水溶性下降。此外,KGM為水溶性膳食纖維的其中一種,可幫助人體的腸胃道蠕動,同時也可以促使腸道益生菌的生長,故為益生元(Prebiotics)物質的其中一種。
