The purpose of this study was to investigate changes in physicochemical properties of apples pre-treated differently with salt and sugar for apple Jangachi. When salt was used, moisture content was decreased by 28.41% to 57.67% at 24 hours and maintained an average 56.92% after 24 hours. However, when sugar was used, moisture content decreased steadily to 41.14% (60h). The pH of the apple pre-treated with salt decreased from pH 4.42 to pH 3.63 at 12 hours. However, in the case of apples pre-treated with sugar, pH decreased from pH 4.52 to pH 4.19 after 48 hours, but was not statistically significant. Conversely, total acidity of apple pre-treated with salt increased from 11.46% to 0.35% during 72 hours. But total acidity of apple pre-treated with sugar decreased to 0.11% at 24 hours and maintained. Sugar content of apple pre-treated with salt increased to 33.1% at 12 hours and maintained. Conversely, in case of sugar pre-treatment, sugar content of apple pre-treated with sugar increased steadily to 45.12% at 72 hours. Salinity of apple pre-treated with salt increased sharply to 15.74% during 24 hours. Lightness (L*) of apple pre-treated sugar was not different from the control group. But apple pre-treated salt decreased slightly. Yellowness (b*) was higher than the control group regardless of pre-treatment group. Sensory evaluation revealed that sugar pre-treatment apples were highly evaluated for flavor, taste, chewiness and overall acceptance.

Pstmodernism is a process which dissolved absolutism and intensified relativism. Jacques Derrida and Michel Foucault made and attack on Hegelianism and meta language used in justification of Nazism. The idea of centralism, such as Angelosaxonism, Europeanism, masculinism, theretofore propagated had lost its way. Hence came 'the death of centralism'. The criteria such as religion, government, morality which made the significant meaning of the development of the western intellect were broken and the only remaining criterion was 'individual evaluation'.
