Effects of various jelly prepared with different concentrations of agar and sugars on overall acceptability of the peach jelly were investigated. The preparations of peach for experimental jelly were carried by the mixture of peach pulp and juice(MPJ), and the extracts from peach(EP). The results were summarized as follows ; 1. The pH for MPJ and EP were 3.95 to 4.31 and 4.21, respectively, and the brix degree were 13.0% and 11.5%, respectively. 2. The jelly prepared with MPJ added 3% sugar and 30% sugar were most effective in appearance, hardness, springiness and overall acceptability. The relation of samples(P<0.001) was found to be significant. On the other hand, the jelly prepared with EP was higher scored than that with MPJ in overall acceptability, but there was no significant differences between samples. 3. The Hunter values of L^*, a^* and b^* were the highest in both the jelly prepared with MPJ and that with EP, added 2% ㅁgar and 10% sugar. However, the L^*, a^* and b^* values of the jelly added MPJ were higher than those of the sample added EP. 4. Texture and color scores of both the jelly added EP became higher as the concentrations of agar and sugars increased and there was significant differences between samples. 5. The relation between springiness and overall acceptability, and L^* value of the jelly added MPJ showed negative at P<0.05. And that between springiness and overall acceptability of the jelly added EP also showed negative.
