The morphological patterns and the cytopathogenicity time of the Vero cells induced by free Cd2+ and pigment-bound Cd2+ were observed by inverted microscope in order to investigate the difference of cadmium toxicity. The Vero cells induced by He

This study was performed to know effect of Yackwa quality when sucrose fatty acid esters(S-570, S-970, S-1570) were added as an emulsifier. In mechanical characteristics, the Yackwa of sucrose fatty acid esters did greatly decrease the hardness, cohesiveness, springiness and gumminess, respectively, and increase the brittleness compared to the Yackwa of non-emulsifier and egg yolk. This tendency showed at the above level of 1.0% S-570, and 0.5% S-970 and S-1570, respectively. In sensory evaluation, the Yackwa of sucrose fatty acid esters increased the softness compared to the Yackwa of non-emulsifiers and egg yolk. There were significantly differences in the preference at 0.5% level of S-970 and 1.5% level of S-1570, respectively compared to other treatments. In conclusion, the 0.5% level of S-970 would be mostly useful level of emulsifier for making Yackwa.
