The dietary effects of soy fiber beni-koji(SBCA) containing chitosan-ascorbate on the body weight and serum lipids in obese rats induced by a high fat diet were investigated. The experimental plots(6 rats per each group) were divided into a normal group(NC), a high fat diet group(HF), a 1% SBCA diet group(SBCA1) and a 2% SBCA diet group(SBCA2), and fed for 6 weeks. Compared with the HF group, the mean body weight and the $R\'{o}hrer$ index of the SBCA1 and SBCA2 groups decreased by $3.4{\sim}7.4%$ and $8.1{\sim}13.9%$, respectively. In particular, the body lipids in the SBCA2 group decreased by 42.3%. The serum triglyceride content decreased by approximately $25.54{\sim}27.34%$ in the experimental diet groups. There was no significant difference in the serum total lipids between the HF and SBCA1 groups. On the other hand, the total lipids in SBCA2 group decreased by 19.12% compared with the HF group. In the SBCA2 group, the total serum cholesterol and LDL-cholesterol content decreased by 6.57% and 41.20% compared with the HF group, respectively, while the HDL-cholesterol increased by 10.0%. The risk factor index(RFI) in the SBCA2 group was decreased remarkably by 58.57%.

Dietary effect of soyfiber beni-koji (SBK) with chitosan-ascorbate (CA) on the level of serum lipids in rats fed a high fat diet was investigated The experimental groups which were divided into high fat diet control group(HC-group), $2\%\;SBK+0.1\%$ CA mixture diet group(CA1-group), $2\%\;SBK+0.15\%$ CA mixture diet group(CA2-group), and $2\%\;SBK+0.2\%$ CA mixture diet group (CA2-group) were fed for 4 weeks. Weight gains in CA2- and CA3-group were $5.3\%\;and\;9.5\%$ lower than that of HC-group, respectively, while there was no significant difference in feed intakes, feed efficiency ratio and organs weight Level of serum triglyceride in $C_3-group\;was\;21\%$ lower than that of HC-group. Level of serum total cholesterol and LDL-cholesterol in CA2- and CA3-group were $22.1\~22.7\%\;and\;58.6\~64.3\%$ lower than those of HC-group, respectively. Atherogenic index decreased with the higher level of CA. Level of lipid peroxide in CA3-group was $24\%$ lower than that of HC-group, while there was no significant difference in GSH(Glutathione-S-transferase) content O type activities of XOD(xanthine oxidase) in the treated groups were lower, especially the activity in CA3-group was $51.6\%$ lower than that of HC-group. Also, O/T ratio of XOD was lower, showing $21.7\~23.5\%$ in treated groups and $34.0\%$ in HC-group(p<0.05). GST activities were 332.52 units in HC-group and $350.28\~355.63$ units in the treated groups, but there were no significant differences among them.
