Dissolution　performance　of　aluminum　in　pre-treatment　and　cooking　process　of　laver　was　studied　in　this　paper.　The　results　showed　that　the　aluminum　can　be　better　removed　after　laver　was　soaked　20　min　and　washed　three　times;　while　cooking　the　laver,　the　dissolution　rate　of　aluminum　increased　as　the　pH　declined　with　the　salt　concentration　increased.　The　highest　dissolution　rate　of　aluminum　in　laver　was　4.61%　when　it　was　boiled.　Dissolution　of　aluminum　in　laver　in　the　human　digestive　system　was　also　studied.　It　revealed　that　the　dissolution　rate　of　aluminum　significantly　increased　with　the　time　extended　in　simulated　gastric,　and　the　highest　dissolution　rate　was　3.98%.　Meanwhile,　the　process　of　dissolution　was　slower　in　the　simulated　intestinal　fluid　and　the　highest　dissolution　rate　was　7.43%　after　4　h.　Although　the　aluminum　content　is　high　in　laver,　the　dissolution　rate　of　aluminum　is　few　when　the　laver　was　cooked　or　digested,　and　the　health　risk　of　aluminum　from　laver　is　limited.
