ABSTRACT

Sericin pulverization process was applied by freezing-thawing of sericin protein concentration solution and physicochemical properties of sericin/chitosan blended films were investigated. In sericin pulverization process by freezing-thawing method, the refrigeration storage at 4℃ maximized gelling between sericin molecules, which increased 10% of recovery ratio from sericin concentration solution that using ultrafiltration procedure. In physicochemical properties of sericin/chitosan blended films, the maximum load of chitosan (6.7kgf) had higher than that of sericin (1.2kgf), and the elongation of sericin and chitosan had 96% and 34%, respectively. Also FT-IR analysis of sericin/chitosan blended films showed that both sericin and chitosan films had amide Ⅰpeak (N-H bond) in 1,521㎝-1 and amide Ⅱ peak (C=O bond) in 1,630㎝-1. In addition, it could confirm compatibility between both materials as indicated by the decrease in the amide Ⅰ peak's absorption value as chitosan content increases.
