木薯的根部可以食用,因此在熱帶和亞熱帶地區有不少居民種植木薯,其所而製成的粉
稱為木薯粉(Tapioca,亦作樹薯粉或生粉)。
品種有甜木薯、苦木薯兩種,甜木薯種的块根含較低的氰酸(cyanic acid),表皮呈
淡青色;苦木薯種的塊根含多量的氰酸,表皮呈褐色,兩者不難區別。塊根又以皮層含
氫氰酸最高,因氫氰酸為毒性,木薯要先刮去外皮,煮熟後才能食用。木薯中毒系由其
所含亞麻苦甙(linamarin)及亞麻苦苷酶(linamarase)水解後析出游離的氫氰酸(
hydrocyanic acid)所致。塊根未煮熟或氰酸未完全分解前就拿來食用,內含的毒素會
轉化為氰化氫(hydrogen cyanide)。中毒后輕者噁心、嘔吐、下痢、昏眩;嚴重者呼
吸衰竭而死亡。還可引起甲狀腺腫,並會傷害視神經和邉由窠浀取br />
