최근 소득수준의 향상과 여성의 사회진출로 인해 우리의 식생활도 많은 부분이 사회화되고 있다. 즉 완전조리식품과 반조리식품이 급격히 증가하고 있다. 기존의 인스탄트식품이 저가격, 반건강 특성으로 생각되어진 반면 최근 고가의 건강 지향적인 반조리식품으로 변화하고 있다. 이러한 경향은 식품가공기술 및 식품포장기술의 향상과 사회적요구에 부합된 결과로 사료된다. 이에 대표적인 경우가 다양한 소스류의 상품화 경향이다. 본 연구개발 사업에서 이루어지는 냉면소스도 가정에서 하기에는 번거롭고, 건강지향적 식생활로 메밀의 수효가 증가하여 냉면의 소비가 증가하리라 생각된다. 현재 시판되고 있는 기존의 몇몇의 제품들이 있기는 하나 제조공정, 보존상태 등에서 많은 문제점이 있다. 따라서 문헌 통하여 기존제품의 배합비를 조사하고, 냉면소스 배합비의 최적화를 위해 10여차례에 걸쳐 20종류의 소스에 대하여 배합비의 변화와 관능검사에 의해 배주스, 양파, 겨자, 마늘, 설탕, 물엿, 소금, 미원, 참기름, 고춧가루, 진간장, 생강즙, 식초, 파인애플로 구성된 소스를 개발하였다. 개발된 소스의 pH, 당도, 염도, 색차를 측정하여 관능검사의 결과와 비교 검토하였고, 식품재료의 차이에 의한 맛의 변화를 보정하기 위한 근거로 사용하였다. 저장성 검사를 위해 일반세균과 대장균을 검사하였다. 그 결과는 다음과 같다. 소비자들의 기호에 맞는 냉면소스를 개발하기 위해 다양한 식품의 배합을 시도하여 상품성이 있을 것으로 판단되는 recipe를 완성하였고, 일반인(주부)들을 상대로 한 호감도 조사에서도 좋은 성적을 나타내었다. 시료를 1주간격으로 한달간 실험한 결과 쇠고기가 들어 있는 제품을 제외하구 대장균은 검출되지 않았으며 일반세균은 위생법의 허용치내에 있었다. 쇠고기가 있는 제품은 가격상승과 저장성에 문제가 있어 이를 제하고 최종적인 레시피를 결정하였다.있었다. 그러나 식이 섭취상태와의 관련성은 나타나지 않았다. 이상에서 생활습관이 신체계측치 및 혈중 지질 농도와 일부 상관을 보이는 것을 알 수 있었으며, 건강위험 요인도 관찰할 수 있었다. 고지혈증은 심혈관계질환의 주요한 위험 인자로 알려져 있으며, 그 유발 요인에는 여러 환경적인 요인과 식이 요인이 있다. 또한 생활습관은 영양소의 섭취량에도 영향을준다. 이처럼 식이 요인과 생활습관은 단독 혹은 상호 영향을 주게 되므로 고지혈증 및 심혈관계질환을 개선하려면 식사요법과 생활습관 교정을 병행하여야 한다. 고지혈증의 원인 중의 하나로 지적되고 있는 음주와 흡연은 상호 유도작용이 있으므로 금연이나 절주를 하고자 할 경우 두가지를 동시에 자제해야 효과적일 것으로 생각된다. 폐경후 여성들에게 발생 빈도가 높은 심혈관질환의 위험요인인 고지혈증을 예방하고자 하는 노력은 폐경후 여성들의 삶의 질적 향상을 위해서도 매우 중요하다. 또한 균형식 섭취와 운동을 통해 혈중 지질 수준을 건강하게 유지하고, 비만으로의 이행을 방지함으로써 심혈관계질환을 예방하도록 하여야겠다.료보다 절반이하 수준이었다. Ferric citrate는 차이가 거의 없었으며 ferrous lactate는 70%수준이었다. 이상의 결과에서 철분강화우유에 사용하기 적합한 철분염은 ferrous lactate, ferric citrate였는데 특히 ferrous lactate는 제품의 이화학적 품질, 생이용성 측면 모두에서 가장 좋은 것으로 나타났다.다 높았으며, 1회당 평균 8.1$\pm$5.1개의 난포란을 회수하였다. investigation can be separated into sampling and analytical uncertainties, it can be used as a criterion where the resources for the inves

The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

The effect of Phellinus linteus methanol extract on the lipid metabolism in the liver of rat was investigated in this study. Rats were randomly divided into 6 groups including the control, $CCl_4$and high fat group plus sub-groups with Phellinus linteus methanol extract administration. Methanol extracts of Phellinus linteus were fed 50mg/kg B.W daily via drinking water. A 1.2mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total six times. The administration of $CCl_4$ increased total cholesterol, TG, LDL and LDL-phospholipid. However, the level of liver cholesterol and triglycerides were significantly decreased while HDL-cholesterol was increased by the extract feeding. The activities of GOT, GPT, AP and LDH were greatly enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ treatment deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract treatment reconstituted the damaged cytoplasm and stimulated mitochondriagenesis. From these results, it was suggested that Phellinus linteus can help to recover the damaged liver function and further may help to prevent senescence diseases such as fatty liver, hypertension and hyperlipidemia.

This study was performed to investigate cholesterol improvement effects of adding fermented defatted soybean grit (FD) and FD added to 5 or 10% Corchorus olitorius (FDC). Cholesterol adsorption in the FD and FDC group was more than 70%. Apolipoprotein AI and CIII improved in HepG2 cells, and a greater improvement effect was shown in FDC than that in FD. We also investigated the effect of FDC on body lipid metabolism and a high-fat diet for 4 weeks. Rats were divided into control (Con), high-fat (HF), HF treated with 20% FD (HF-FD), and HF treated with 20% FDC (HF-FDC) groups. Plasma total cholesterol and low density lipoprotein-cholesterol concentrations, hepatic total cholesterol, and triglyceride contents were significantly lower in the HF-FDC group than those in the HF group. Additionally, fecal total cholesterol and triglyceride contents increased in rats treated with FDC. Hepatic 3-hydroxy-3-methylglutaryl-coenzyme A reductase activities were significantly lower in the HF-FDC group than those in the HF group.

This study investigated the effects of fermented black raspberry (BR) and red ginseng (RG) extract co-treatment on lipid metabolism and obesity in rats fed with a high fat/high cholesterol diet (HFHCD) for 12 weeks. Compared to the corresponding values in rats fed with a HFHCD, total cholesterol and low-density lipoprotein (LDL)-cholesterol and triglyceride levels decreased whereas high-density lipoprotein (HDL)-cholesterol levels increased in rats treated with fermented BR and RG extracts. These extracts significantly increased the expression of HMG-CoA reductase, LDL receptor, and sterol regulatory-element-binding protein-2 (SREBP-2) mRNA, but decreased the mRNA expression of SREBP-1. Additionally the serum levels of leptin and fatty acid synthase were decreased. Moreover, supplementation with fermented BR and RG effectively increased fecal cholesterol excretion. These results suggest that fermented BR and RG extracts might be effective at preventing hypercholesterolemia and obesity.

Rubus coreanus has been used as a traditional medicine in Asia because of its various pharmacological properties. This study examined the effects of protocatechuic acid (PCA), one of phenolic compounds derived from R. coreanus on the lipid metabolism in high cholesterol diet-induced mice. A total of 30 male C57BL/6 mice were divided into 5 groups with 6 mice in each group as follows: (1) Control mice received normal diet (ND). (2) Mice received high-cholesterol diet (HCD) plus water, 10% sucrose solution and treated daily oral phosphate-buffered-saline (PBS) of equal volumes through gavage. (3) Mice received HCD and treated daily with 25 mg/kg b.w./day of PCA (4) with 50 mg/kg b.w./day or (5) with 10 mg/kg b.w./day of simvastatin via oral gavage for 12 weeks. Body weights were measured weekly for a period of experiment. After treatment, liver, thymus, spleen and kidney were harvested and weighed, and the lipid metabolite profiles (total cholesterol, triglyceride (TG), HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c) and liver-damaging markers (GOT and GPT) in serum were examined. PCA significantly reduced the total cholesterol, TG, LDL-c level and increased the HDL-c level. PCA administration also significantly reduced the levels of GOT and GPT. These results indicate that the PCA could be used as a functional material for lowering lipid and an adjuvant for the treatment of hyperlipemia.

Despite the risk of high altitude disease (HAD), raising cattle at higher altitudes does have advantages such as beef quality due to minimal chance of infection and stress. The ideal situation is to determine the optimum altitude suitable for raising cattle while at the same time minimizing the risk of HAD. Therefore, in this study, we documented the health status of three groups of steers, raised at three different altitudes (200m, 400m and 800m) in Gangwon province, using routine hematological, biochemical and hormonal tests. The red blood cell counts and hemoglobin concentration were highest in the 800m group, and lowest in the 200m group, possibly due to hypoxia induced myeloid and erythroid stimulation. The mean concentration of AST, BUN and serum cortisol were lowest in the 800m. These findings suggest the stress factor will contribute the general health status of animal and indicate a difference in the Hanwoo groups raised at 800m compared to 200m, where the cattle raised at the higher altitude exhibit better health status compared to the lower altitude, possibly due to less stressful environment in the higher altitude.

Obesity, the leading metabolic disease, is a prevalent health problem in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and even cancer. In this study, we investigated the effects of dip-sauce for meat containing Garcinia cambogia extract (GC) on the lipid accumulation and body weight reduction in rats fed high-fat diet for three months. Eighteen Sprague Dawley male rats of five-week-old were randomly assigned to one of three groups; normal chew diet (NCD) group, high-fat diet plus GC-noncontaining dip-sauce (HFD) group, and HFD plus GC-containing dip-sauce (HFD+GC) group. Co-administration of GC-containing dip-sauce (5 g/kg body weight/day) with HFD significantly attenuated cumulative body weight gain, compared with NCD or HFD groups. Both epididymal and perirenal fat pad weights in the HFD plus GC group were significantly lower than those of HFD or NCD groups. Administration of GC-containing dip-sauce also resulted in significant reduction in the serum levels of total cholesterol, total lipid, and triglyceride, compared with NCD or HFD groups. Thus, GC-containing dip-sauce confers beneficial effects to pathological states associated with metabolic disorder via its anti-obesity and lipid lowering properties.

In order to determine the moisture content level for safe storage of wild vegetables, drying characteristics and water vapor sorption characteristics of four vegetables, i.e., zucchini slice, sweet potato stem, taro stem, and platycodon, were investigated. The drying curves of these vegetables were consisted of three characteristic stages which were the initial settling down period, the constant drying rate period, and the falling drying rate period. And the falling rate period of the vegetables showed 2 or 3 parts of falling rate. All of the falling rate curves of the vegetables showed upwardly convex shape which is known as a characteristic pattern for the drying of fibrous food materials. The critical moisture contents of the vegetables were $8.29{\sim}9.75,\;10.40{\sim}15.08,\;9.51{\sim}14.52\;and\;3.29{\sim}3.56g\;H_2O/g$ dry solids for zucchini slice, sweet potato stem, taro stem, and platycodon, respectively. Activation energy values of drying rate during falling rate period were 2.30, 2.11, 4.97, and 2.80 kcal/mol for zucchini slice, sweet potato stem, taro stem, and platycodon respectively. The BET monolayer moisture contents of the vegetables were $10.05{\sim}13.59,\;9.49{\sim}12.69,\;9.50{\sim}16.48\;and\;5.01{\sim}5.44g\;H_2O/g$ dry solids for zucchini slice, sweet potato stem, taro stem, and platycodon, respectively. And these values were found to be very compatible with the values of the critical moisture content. Consequently, it was found that the moisture of these vegetables should be removed below the BET monolayer moisture content or below the critical moisture content for the long term storage.

This study was conducted to investigate the effect of Hijikia fusiforme extracts on serum lipid and liver antioxidative enzyme activities in triton-induced hyperlipidemic rats. Sprague-Dawley male rats divided into 7 groups : We injected saline to a normal group (N), saline and tween 80 to control groups (CS, CT) and tot extracts to experimental groups (CSA, CTEtOH, CTE, CTH) for 7 days and then injected triton at the last day. Serum and liver free cholesterol contents were significantly lower in hexane-treated group (CTH) than control group (CT) whereas serum HDL-cholesterol content was higher in aqueous extract group (CSA) than control group (CS). Total cholesterol and phospholipid contents in serum and liver were lower in aqueous extract group (CSA) than control group (CS). Serum and liver triglyceride contents were significantly lower in ethanol (CTEtOH) and hexane treated group (CTH) than control group (CT). Thiobarbituric acid reactive substances of liver were lower in tot extract groups (CSA, CTEtOH, CTE, CTH) than control groups (CS, CT). Superoxide dismutase activities in liver were significantly lower in aqueous extracts group (CSA) and hexane treated group (CTH) than control groups (CS, CT). Liver catalase activity was the lowest in ethylacetate extract group. These results showed that some Hijikia fusiforme extracts have reduction effect of lipid and antioxidative effect in triton-induced hyperlipidemic rats.
