Abstract

Effects of chitosan-soybean curd (prepared using chitosan as a coagulant), commercial soybean curd and chitosan powder on serum lipid metabolism were investigated with rats fed high-fat diet for 6 weeks. Food intake of experimental groups fed high-fat (HF), chitosan-soybean curd (CSC), soybean curd (SC), or chitosan powder (CP)diet was lower compared to t]tat of normal group. Body weight gain was lower in rats fed the CSC, SC and CP diets than in rats fed the HF diet. There was no significant difference in total cholesterol concentration among all groups, but HDL-cholesterol concentration was higher and LDL-cholesterol concentration was lower in rats fed the CSC, SC, CP diets than in rats fed the HF diet. Total lipid level was lower in rats fed the SC and CP diets than in rats fed the HF diet. Increment of triglyceride level and decrement of phospholipid level in rats fed the HF diet were recovered significantly by the CSC, SC and Cf diet. Our results indicate that chitosan-soybean curd prepared under the commercial processing condition may provide the beneficial effect on lipid metabolism even though its effect didn't show any significant difference compared to that of commercial soybean curd under the present experimental conditions.

키토산을 응고제로 사용하여 상업 적 조건에서 제조한 두부와 일반 두부 및 키토산 분말을 고지질 급여 흰쥐 에6주간 급여한 후 혈청 지질대사에 미치는 영향을 조사하였다. 그 결과, 흰쥐의 식이 섭취량은 정상 식이군(N)에 비해 모두낮았으며, 키토산 두부 첨가군(CSC)과 키토산 분말 첨가군(CP)의 식이섭취량이 특히 낮았다. 체중 증가량은 고지질 식이군(HF)에 비해 CSC군, 일반 두부 첨가군(SC) 그리고 CP군들은 모두 유의적으로 낮았으며, 특히 CP군이 가장 낮은 체중증가를 나타내었다. 혈청중의 총 콜레스테롤 농도는 전 실험군간에 유의적인 차이는 없었으나, HDL-콜레스테롤 함량에서는 CSC, SC, CP군 모두 HF군에 비하여 높게 나타났다 따라서 총 콜레스테롤중 HDL-콜레스테롤이 차지하는 비율은 CSC, SC, CP군이 HF군에 비하여 높고 동맥경화지수는 반대로 낮게 나타났다. LDL-콜레스테롤 농도는 HF군에 비해 CSC, SC, CP 실험 군에서 유의적으로 낮게 나타났다. 총 지질 함량에서는 HF군에 비하여 SC와 CP군에서 유의적으로 감소하였다. 고지질 식이에 의해 증가한 중성지질 및 감소한 인지질 함량은 CSC, SC, CP군에서 유의적으로 회복되었다. 본 실험 에서는 HF군에 비해 CP군 뿐 아니라 CSC, SC군에서 HDL-콜레스테롤 및 인지질 농도의 증가, 중성지질 및 LDL-콜레스테롤 농도의 감소가 관찰됨으로써 상업용 키토산 두부가 고지질 관련 성인병 예방 및 치료에 효과가 있을 것으로 사료되었다. 그러나 현 실험조건하에서는 일반두부와 키토산 두부간에 효능에서 유의적인 차이를 발견하긴 어려웠다.
