Chitosan-ascorbate (CA)를 표면처리한 후 에서 감압건조한 과메기(VD-과메기)의 품질특성과 고지방식이 흰쥐의 혈청지질과 항산화계 효소활성에 미치는 영향을 조사하였다. VD-과메기의 제조기간은 360~4800.2~0.5128.3~135.040℃40℃서 감압건조하는 방법은 제조기간을 크게 단축시킬 뿐만 아니라 과메기의 위생성과 영양성을 높일 수 있는 방법으로 산업적 활용이 기대
Quality characteristics of Kwamaegi (semi-dried saury) prepared by treatment of chitosan-ascorbate (CA) and vacuum drying at (VDK), and the effect of the Kwamaegi on serum lipid profiles and anti-oxidation-related enzyme activity in rats fed high fat diets were investigated. The preparation periods were hr in VDK, while naturally dried Kwamaegi (NDK) took 360480 hr. Total microbe contents of VDK and NDK were and 8.2 log CFU/g, respectively. There was no significant difference in amino-nitrogen content. Compared with NDK, the acid and peroxide value, and fishy flavor of VDK40 (dried at ) were significantly lower, and the texture, color and overall acceptability were higher. In animal experiments, weight gain, content of LDL-cholesterol and lipid peroxide, activities of total (T) and O type (O) xanthine oxidase, and the O/T ratio (%) were significantly lower in the VDK40 diet group than in the NDK diet group. The content of HDL-cholesterol in the VDK40 diet group was higher than in the NDK diet group. These results suggest that preparing CA-treated Kwamaegi with vacuum-drying at can be applied throughout the year, and may shorten preparation time and improve its microbiological safety and nutritional values.
