<P>PROBLEM TO BE SOLVED: To produce an edible film effectively preventing moisture transport in food, such as moisture transition in food and moisture vaporization from food, and having a general purpose food material as the raw material. <P>SOLUTION: This polyion complex film is obtained by bringing a protein-containing aqueous solution which becomes cationy in an environment of less than an isoelectric point into contact with an anionic high polymer-containing aqueous solution so as to produce on a contact surface. It is possible to effectively prevent moisture transport in food by using the film, and produce food which enables for a longer period enjoyment of palate feeling, water content and strength which are likely to be spoiled by preservation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
