Abstract

Color value, total color difference $({\triangle}E)$, puncture strength (PS), tensile strength (TS), percent elongation(%E) at break values, and water vapor permeability (WVP) were determined for water-soluble chitosan films added with soy protein isolate (SPI) and $CaCl_2$. Mechanical and water vapor barrier properties of the chitosan films were affected by SPI and $CaCl_2$ concentrations. PS value $(174.5-448.8\;g_f)$ of the chitosan films increased with increasing concentration of $CaCl_2$ TS value of 0.05% $CaCl_2$-added chitosan films significantly increased to 1.58 MPa compared to 0.06 MPa of the control. %E values ranged from 12.25 to 44.80% and increased with increasing concentration of $CaCl_2$. WVP of $CaCl_2$-added films was lower than that of SPI-added films.

수용성 키토산 필름 용액에 분리 대두단백질(SPI)과 $CaCl_2$ 첨가가 키토산 필름의 물성에 미치는 영향을 알아보기 위해 이들을 첨가하여 제조한 필름의 색도, puncture strength, 인장강도와 신장률, 수증기투과도를 측정하였다. 필름의 puncture strength는 0.15% $CaCl_2$를 첨가하여 제조한 키토산 필름이 $458.8\;g_f$로 대조구의 $174.5\;g_f$보다 약 2.5배 증가된 가장 높은 값을 나타냈다. 인장강도의 경우 대조구가 0.06 MPa인 반면에 0.05% $CaCl_2$를 첨가한 키토산 필름은 1.58 MPa로 가장 높은 값을 보였고 SPI를 2.5% 첨가한 필름은 0.73 MPa로 나타났다. 필름의 신장률은 대조구가 12.25%인 반면 0.15% $CaCl_2$를 첨가한 필름은 44.80%로 $CaCl_2$의 양이 증가함에 따라 커지는 경향을 보였으며, 수증기투과도는 $CaCl_2$를 첨가한 필름이 SPI를 첨가한 필름보다 더 낮은 값을 보였다.
