  • "Manggaedduk" produced specially in Uiryeong province, Gyeongnam, Korea is manufactured by traditional method using rice powder, sweet azuki bean paste, and leaves of Smilax china (called as Manggae-leaf). Moisture content of leaves did not show significant differences bay salt and purified salt treatment. The content was lower as the salt concentration increased. Shear force was higher in leaf salted with purified salt at room temperature than that salted with bay salt. On the other hands, the force was more higher in the leaves salted with bay salt at low temperature ($4^{\circ}C$). The shear force was higher as the concentration of both salts used for salting solution increased. As storage period was extended, shear force of salted leaf was weakened. Whiteness (L) and yellowness (b) of leaves stored at room temperature were higher than those stored at $4^{\circ}C$, although the redness (a) of Hunter value was not significantly different between storage temperatures. Salt concentration influenced lightness and yellowness, color of salted leaves stored at $4^{\circ}C$ resulted in enhanced greenness as compared to the leaves stored at room temperature. Thus, this study investigated the optimal storage conditions, salting conditions and storage temperatures of Smilax china leaves.
