Abstract

Effects of persimmon peel powder on physico-chemical properties in 60 pigs was investigated. The pigs were randomly assigned to one of the four dietary treatments: 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 1% persimmon peel powder) 3) T2 (commercial feed supplemented with 3% persimmon peel powder) 4) T3 (commercial feed supplemented with 5% persimmon peel powder). In proximate composition, moisture of pork from treatment groups were decreased by addition level increased than that of control but crude fat was increased (p<0.05). Crude protein and crude ash was no significantly difference. The total cholesterol, HDL-cholesterol and triglyceride of treatment groups was higher than that of control.. LDL-cholesterol of control was higher than that of treatment groups. The WHC (water holding capacity) of control was higher than treatment groups and shear value was higher in treatments group (p<0.05). pH was not significantly different between control and treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05). The meat color of treatment group showed whiter and redder than that of control owing to higher L/sup */, a/sup */ and b/sup */ value. In fatty acids, stearic acid contents of treatment groups were higher than that of control. The unsaturated fatty acid/saturated fatty acid ratio of the control, T1 T2 and T3 were 1.78, 1.71. 1.69 and 1.66, respectively and control had higher than the treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05).

본 연구는 감껍질 분말을 사료내에 첨가하여 그 첨가수준(0, 1, 3, 5%)에 따라 돈육의 이화학적 특성을 검토하고자 돼지 60두를 공시하여 사양하였다. 감껌질 분말 사료의 급여수준에 따른 돈육의 일반성분 중 수분은 감소하는 경향을 보였고, 조지방은 증가하는 경향을 나타내었으며(p<0.05), 조단백질과 조회분은 유의성이 없었다. 총콜레스테롤, HDL-콜레스테롤, 중성지방은 처리구에서 높았고, LDL-콜레스테롤은 대조구보다 처리구에서 낮았다(p<0.05). 보수성은 대조구에서 높았으며, 전단력은 처리구에서 높았고, pH는 유의성이 인정되지 않았다. 육색은 처리구에서 대조구보다 비교적 L/sup */값이 높고 a/sup */, b/sup */값이 높아 밝고, 붉은색을 뛰었다. 지방산중에 처리구의 stearic acid함량이 높았고, 포화지방산과 불포화지방산의 비율은 대조구가 1.78, 처리구는 1.71, 1.69와 1.66으로 대조구가 더 높게 나타났다(p<0.05). 관능평가 결과 감 껍질분말의 급여구에서 연도, 다즙성, 풍미가 높은 점수를 나타내었고, 특히 T3구에서 유의적인 차이를 보였다(p<0.05).
