The effects of film processing conditions on the water vapor permeability (WVP), the solubility of film's protein (SFP) and the soluble film's meterials amount (SFMA) were investigated to establish the conditions for preparing biodegradable and edible Alaska Pollack meal protein isolate (APMPI) film. ms of film were decreased with increasing plasticizer concentration but those were decreased with decrement of APMPI's pH values. SEPs were decreased with increasing APMPI's pH and plasticizer concentration. SFMAS were also strongly affected by plasticizer concentration and APMPI's pH. In the case of adding different plasticizers, WVP was increased in order as follows: glycerol, polyethylene glycol and sorbitol but SFMA showed inverse order.
