This study investigated the lipid profiles for the possible improving activity of insoluble dietary fiber extracted from cabbage waste discarded during kimchi manufacture and market distribution. Enzyme-treated Insoluble Dietary Fiber (EIDF) is the remnants of crude dietary fiber (CDF) treated by α-amylase, protease, and amyloglucosidase after removal of soluble materials from cabbage waste. The insoluble dietary fiber of CDF and EIDF in cabbage waste was 65.33±0.33% and 73.57±0.09%,

To examine the effects of EIDF on plasma cholesterol concentration, two group of rats were fed either a high fat diet (HFD) or a HFD containing 0.1~1.0% EIDF for 4 weeks. The body weight of all groups was not significantly different (p<0.05) but the body weight of EIDF+HFD groups was less than that of the HFD group (p<0.1). Compared with the HFD group, EIDF also lowered serum levels of total triglycerides to 11.2~23.3% and cholesterol to 26.8~28.5%. In EIDF+HFD groups, the HDL-cholesterol level increased by 7.2~26.1%, while LDL-cholesterol especially decreased by 51.0~ 61.4% and VLDL-cholesterol by 16.9~26.4%. The atherogenic index of EIDF+HFD groups was also reduced twice that of the HFD group. From these results, EIDF from cabbage waste could be a potential effective food ingredient for improving lipid profiles.
