In this study, to activate the industrialization and to improve the quality of Toha-jeot by shortening the fermentation period, we investigated the changes in the nutritional components of Toha-jeot. salt-fermented Toha shrimp( Caridina denticulata denticulata $D_{E}$ $H_{AAN}$) which was salted with a low-salt group and high-salt group during fermentation. In this experiment. there are four groups of Toha-jeot which were manufactured with 15% ratio of common salt: the first group containing 2% wheat bran (w2%-L). the second high-salt group containing 2% wheat bran( w2%-H) , the third low-salt group containing 4% wheat bran (w4%-L) and the last high-salt group containing 4% wheat bran(w4%-H). These four groups were refrigerated at 4${\pm}$1$^{\circ}C$ and then taken out for analysis at three month intervals during 9 month. Among the free amino acid contents in Toha-jeot, 22 kinds were detected. 6 month after the fermentation when the quantity of the amino acid contents in Toha-jeot is highest, ornitine, glutamic acid, leucine. alanine. lysine and valine occupy the majority, in the order of abundance. In cases of nucleotides. 6 month after the fermentation. from the groups w2%-L, w2%-H and w4%-L, inosine and IMP were not detected. and hypoxanthine, AMP, ADP were detected but 9 month after the fermentation ADP was not detected. The main constituents of fatty acid were as follows : (a) from w2%-L, w2%-H, 6 month after the fermentation. $C16:0$, $C12:0$, $C18:1$, $C18:3$, and $C16:1$. (b) from w4%-L. 6 month after the fermentation, $C18:3$, $C16:0$, $C12:0$ and $C18:1$. (c) from W4%-H, $C16:0$, $C12:0$, $C18:3$ and $C18:1$. In case of mineral contents. Na, Ca. K. Mg, Fe. Zn, Mn and Cu were detected according to the magnitude of the quantity. From the group w4%-H, high quantity of Na was detected during the total fermentation period. In case of color value, from the groups w2%. the values of L. a. b were highest after 6 month fermentation and were decreased after 9 month fermentation, while from groups w4%, the values of L, a, b were gradually decreased after 3 month fermentation.ion.
