Abstract PROBLEM TO BE SOLVED: To provide a novel water absorptive polymer obtained by crosslinking a polyglutamic acid with a metal. SOLUTION: The water absorptive polymer is constituted by crosslinking a polyglutamic acid and/or a polyglutamic acid salt with a trivalent metal. Use of aluminum, particularly its double salt which is alum as this metal can provide an edible water absorptive polymer.
