        본 연구는 포도주의 첨가가 돈육 patty의 품질 및 기호성에 미치는 영향을 규명하기 위하여 제조과정에 포도주를 첨가하지 않은 돈육 patty(대조구), 포도주를 1% 첨가한 돈육 patty(WP-1), 포도주를 3% 첨가한 돈육 patty(WP-2) 그리고 포도주를 5% 첨가한 돈육 patty(WP-3) 등 네 종류의 돈육 patty를 제조하였다. 수분, 조단백질, 조지방 및 조회분은 시료들 사이에 유의한 차이가 없었다. 돈육 patty의 $L^*$ 및 $b^*$값은 대조구가 포도주 첨가구보다 유의하게 높았다(p<0.05). 그리고 열량, 보수력, VBN 함량 및 총균수는 시료들 사이에 차이가 없었으나 pH 및 TBARS값은 WP-2 및 WP-3이 대조구 및 WP-1보다 유의하게 낮았다(p<0.05). 총아미노산 함량은 대조구, WP-1, WP-2 및 WP-3이 각각 18.29, 17.83, 17.85 및 17.37%로 시료들 사이에 유의한 차이가 없었다. 지방산 조성은 시료들 사이에 유의한 차이가 없었으며, 포화지방산은 palmitic acid가 가장 많았고, 불포화지방산은 oleic acid가 가장 많았다. 가열 돈육 patty의 풍미, 조직감 및 다즙성은 시료들 사이에 유의한 차이가 없었지만, 맛과 종합적인 기호성은 WP-2 및 WP-3이 대조구 및 WP-1보다 우수하였다. This study was carried out to investigate the effects of adding wine on the quality and palatability of pork patties. Pork patties were prepared by four types: pork patty without wine (control), pork patty containing wine 1% (WP-1), pork patty containing wine 3% (WP-2), and pork patty containing wine 5% (WP-3). Moisture, crude protein, crude fat, crude ash, Hunter's $a^*$ value, calorie, water holding capacity, VBN content, total bacterial counts, amino acid composition, fatty acid composition, flavor, texture, and juiciness were not significantly different among the pork patties. The $L^*\;and\;b^*$ values of the control patty was higher than those of the WP-1, WP-2, and WP-3 (p<0.05). The pH and TBARS value of the WP-2 and WP-3 were lower than those of the control patty and WP-1 (p<0.05). The total amino acid content of the control patty, WP-1, WP-2, and WP-3 were 18.29, 17.83, 17.85, and 17.37%, respectively. Palmitic acid was the most abundant among saturated fatty acids while oleic acid was the most abundant unsaturated fatty acid in the four groups. The taste and palatability of the WP-2 and WP-3 were superior to the control patty and WP-1 (p<0.05).

        본 연구는 감귤부산물 TMR 사료 급여가 한우등심의 영양성분 및 기호성에 미치는 영향을 연구할 목적으로 수행하였다. 시료는 감귤부산물 TMR 사료를 급여하지 않은 한우등심(TMR-0)과 감귤부산물 TMR 사료를 급여한 한우등심(TMR-1)으로 하였다. TMR-0는 비육우용 배합사료와 건초를 분리 급여하면서 관행적으로 사육하였으며, TMR-1은 육성기 및 비육전기 일부(약 17개월)를 TMR-0와 같은 방법으로 사육한 후 나머지 10개월(비육전기 및 후기) 동안은 감귤부산물 TMR 사료를 급여하였다. 한우등심의 수분, 조단백질, 조회분, 콜레스테롤 및 열량은 TMR-0 및 TMR-1 사이에 유의성이 없었지만, 조지방은 TMR-1이 유의하게 높았다(p<0.05). Ca 및 Na는 TMR-1이 TMR-0보다 유의적으로 높았고, P는 TMR-0가 높았으나(p<0.05), Mg, K, 비타민 $B_1$ 및 비타민 $B_2$는 시료들 사이에 유의성이 없었다. 한우등심의 구성아미노산 총량은 TMR-0 및 TMR-1이 각각 17.81 및 17.98%로 비슷하였으며, 유리아미노산 총량은 각각 139.46 및 149.15 mg/100 g으로 유의성이 없었다. 불포화지방산 중 가장 많이 함유되어 있는 것은 oleic acid로 TMR-0 및 TMR-1이 각각 45.01 및 49.38%이었고, 포화지방산 중 가장 많이 함유되어 있는 것은 palmitic acid로 TMR-0 및 TMR-1이 각각 28.39 및 26.52%이었다. 한우등심의 관능적인 맛, 풍미 및 다즙성은 시료들 사이에 유의한 차이가 없었으나, 연도 및 전체적인 기호성은 TMR-1이 TMR-0보다 유의적으로 우수하였다(p<0.05). The purpose of this research was to study the effects of feeding TMR (total mixed ration) dietary citrus by-products on nutritional composition and palatability of Hanwoo loin. Samples for the experiment consisted of Hanwoo loin that was not fed citrus by-products (TMR-0) and Hanwoo loin that was fed citrus by-products during fattening periods (TMR-1). The control (TMR-0) Hanwoo loin was fed by general practical feeding (roughages and concentrates were fed separately); the TMR-1 Hanwoo loin was fed identically to TMR-0 until 17 months yearling, but fed citrus by-products for 10 months after then. The levels of the moisture, crude protein, crude ash, cholesterol, Mg, K, vitamin $B_1$, vitamin $B_2$, total amino acids ($17.81{\sim}17.98%$), and total free amino acids ($139.46{\sim}149.15mg/100g$) were not significantly different between TMR-0 and TMR-1. The contents of the crude fat, Ca, and Na of TMR-1 were greater than those of TMR-0 (p<0.05). Oleic acid ($45.01{\sim}49.38%$) was the most abundant anions unsaturated fatty acid while palmitic acid ($26.52{\sim}28.39%$) was tile most abundant saturated fatty acid in both groups. In case of sensory scores, taste, flavor, and juiciness were not significantly different between TMR-0 and TMR-1. However, tenderness and palatability preference of TMR-1 were higher than those of TMR-0 (p<0.05).

        This research investigated the effect of the Chaenomelis fructus(CMF) on Alzheimer's disease. The effects of the CMF extract on the behavior in the Morris water maze experiment; the expression of IL-1β, TNF-α, ROS on the microglial cell; IL-1β mRNA, TNF-α mRNA, CD68/GFAP and MDA on the brain tissue; the infarction area of the hippocampus, and brain tissue injury in the mice with Alzheimer's disease induced by βA were investigated. The CMF extract group showed a significant inhibitory effect on the memory deficit on the mice with Alzheimer's disease induced by βA in the Morris water maze experiment. The CMF extract group suppressed the over-expression of IL-1β, TNF-α, IL-1β and TNF-α mRNA, ROS, MDA, CD68/GFAP in the mice with Alzheimer's disease induced by βA. The CMF extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer's disease induced by [3A. This study suggest that CMF may be effective for the prevention and treatment of Alzheimer's disease.
