Abstract

This study demonstrates that pork cholesterol levels are reduced in fattening stage swine fed $\beta-cyclodextrin({\beta}-cyclodextrin)$. The study subjects were 120 swine fed their respective chow diets containing 0, 5, 7, or 10% $\beta$-cyclodextrin for 35 consecutive days. Plasma total lipids, triglyceride and total cholesterol of the $\beta$-cyclodextrin treated group were significantly lower than those of the control group (p<0.05). The levels of plasma lipid were significantly decreased by 63.22 mg, 73.98 mg, and 82.12 mg in the fattening swine group fed $\beta$-cyclodextrin at 5%, 7%, and 10%, respectively, compared to those in the control group (p<0.05). When 5, 7, and 10% $\beta$-cyclodextrin was administered to fattening swine, the triacylglyceride levels were decreased by 56.24 mg, 55.48 mg, and 60.02 mg, and total cholesterol concentration was reduced by 25.05 mg, 27.17 mg, and 30.19 mg, respectively, compared to those in the control group (p<0.05). Excretion of total steroid significantly (p<0.05) increased with the increasing amount of $\beta$-cyclodextrin supplementation. The cholesterol levels of swine back fat, belly, loin, and ham were significantly decreased with increasing $\beta$-cyclodextrin supplementation (p<0.05). The pork cholesterol was significantly (p<0.05) reduced by 15.31% in the $\beta$-cyclodextrin treated group, compared to that of the control group. These results suggest that feeding $\beta$-cyclodextrin to fattening swine may produce novel functional pork with low cholesterol levels.

본 연구는 비육말기 돼지에서 베타사이클로덱스트린$\beta$-cyclodextrin의 급여가 돈육의 콜레스테롤 수준을 낮춘다는 것을 나타내고 있다. 120마리의 돼지에게 0, 5, 7, 10%의 $\beta$-cyclodextrin를 함유하는 사료를 35일 간 급여하였다. 혈액 총지질, 중성지방 및 총 콜레스테롤 함량은 $\beta$-cyclodextrin첨가구가 대조구에 비해서 낮게 나타났으며 처리구간 통계적인 유의차가 나타났다(p<0.05). 혈액 100 mL 당 지질은 대조구와 비교할 때 $\beta$-cyclodextrin 5.0%, $\beta$-cyclodextrin 7.0% 및 $\beta$-cyclodextrin 10.0% 첨가구에서 각각 63.22 mg, 73.98 mg, 82.12 mg의 유의적인 감소를 나타냈으며, 중성지방 56.24 mg, 55.48 mg, 60.02 mg, 총콜레스테롤 25.05 mg, 27.17 mg, 30.19 mg의 유의성 있는 감소경향을 보였다(p<0.05). 총스테로이드의 배설은 $\beta$-cyclodextrin 첨가수준이 증가할수록 대조구에 비해서 유의적으로 높게 나타났다(p<0.05). 돼지고기의 부위별, 등지방, 삼겹살, 등심 및 햄의 콜레스테롤 함량은 대조구에 비해서 $\beta$-cyclodextrin 첨가수준이 높아질수록 유의적인 감소경향을 나타냈다(p<0.05). 돼지고기의 콜레스테롤 함량 감소율은 $\beta$-cyclodextrin 첨가구가 대조구와 비교할 때 15.31% 이상의 높은 감소율을 나타냈다(p<0.05). 본 연구 결과는 비육말기 돼지사료 내 $\beta$-cyclodextrin를 혼합 급여하여서 콜레스테롤 함량이 낮아진 새로운 기능성 돈육을 생산할 수 있음을 시사해준다.
