This study compared the physicochemical properties of root hair of white ginseng (WG), root hair of tissue cultured mountain ginseng (MG), root hair of red ginseng (RG) and extruded ginseng samples. The comparison of crude ash and total sugar resulted insignificant differences between extruded and raw samples. MG had a higher content of crude ash, crude protein, amino acids and polyphenolic compound than WG and RG; the total sugar and reducing sugar were highest in RG. Crude fat and acidic polysaccharide in RG and WG were similar to and higher than MG. Crude saponin of treated samples WG1 (moisture content 25%, barrel temperature $110^{\circ}C$) and WG3 (moisture content 35%, barrel temperature $110^{\circ}C$) were 9.80% and 9.73%, respectively, which were the highest among ginseng samples. In conclusion, the extrusion process can be applied to red ginseng manufacturing, and some characteristics of MG were higher than in RG and WG.

The contents of proximate components of the polished adn unpolished Job's tears, Coix agrestis, were determined. And also the phisical and the chemical properties of fatty acids composition and the oxidative rancidity of the crude oil extracted from Job's tears were examined. RESULTS : 1.The contnets of moisture, total ash, crude protein, crude fat, and carbohydrate in Job's tears were shown to be about 9.2%, 2.1~5.0%, 19.5~20.8%, 3.7~7.2%, 60.7~67.0%. 2. The average values of specific gravity, refractive index iodine value, saponification value, acid value of the crude oil extracted from Job's tears were 0.917~0.920, 1.47574, 107~111, 198~199, 1.3~2.0, respectively. 3. The fatty acids composition in the crude Job's tears oil showed oleic acid 48.97~49.97%, linoleic acid 37.33~36.16%, palmitic acid 13.70~13.87%. 4. Generally, the peroxide values and thiobarbituric acid values of the Job's tears oils and control during 40 storage days at 40±1℃ showed very low increase. After 32 days, the peroxide values and TBA values of soybean oil showed higher than those of the Job's tears oils. Conclusively, the Job's tears oils were shown to be more stable than the soybean oil.

본 연구는 비거세돈 12두를 이용하여 돼지 복강 및 피하지방 감소 후보 항체를 생체 주사 처리 시 체중, 분 소화율 및 혈액 대사물질 등 영양생리대사에 미치는 영향을 조사하고자 실시하였다. Choi 등(2010)에서 개발된 돼지 복강 및 피하지방 감소 후보 항체를 피하 주사하였을 때 주사 후 4주까지 평균 체중은 수치적 증가가 발생했으나(P>0.05), 전 기간에 걸쳐 수치적 증가를 보여 항체의 처리로 인한 영향보다는 돼지의 일반적인 성장에 기인하는 것으로 판단된다. 항제 주사 처리 시 건물, 조단백질, 조지방 및 조섬유의 분 소화율은 항체 주사 전, 후 및 시험구 간의 통계적 유의성이 나타나지 않았다(P>0.05). 조회분 소화율의 경우 항체 주사 후 2주째 control에서 감소를 및 4주째 NAb에서 증가를 보였으나(P< 0.05), AAb 및 SAb에서는 유의적 변화가 없었다. 혈액 대사물질의 변화에서는 항체 주사 후 4주의 AAb 및 SAb에서 BUN 농도가 유의적으로 증가하는 것으로 나타났다(P<0.05). 하지만, 후보 항체 주사 전에서도 유사한 패턴으로 유의적 증가를 보여 항체 처리에 의한 차이보다는 개체간의 차이로 사료된다. 혈액 내 glucose 및 TG 농도는 후보 항체 처리에 의한 유의적 차이는 나타나지 않았다(P>0.05). 체지방 함량과 밀접한 관계에 있는 혈액 내 TC 농도에서는 control 대비 후보 항체 주사 후 4주차 AAb 및 SAb에서 유의적 감소가 나타나(P<0.05), 체지방 감소가 일어나고 있음을 간접적으로 추론할 수 있다. 이상의 결과를 볼 때, 본 연구에서 이용된 AAb 및 SAb는 in vivo 영양생리대사에 부정적 영향을 미치지 않는 안전한 항체로 판단된다.

Proximate compositions of black rice and antioxidative effects of its methanol extract on refined perilla oil were investigated. Black rice seeds were composed of water 12.4%, crude protein 7.9%, crude fat 2.2%, crude fiber 1.0%, ash 1.4% and N-free extract 75.1%. The hexane and 80% methanol fractions in yields were higher than 80% ethanol and chloroform. In AOM(active oxygen method) test, antioxidative effects of black rice added to the refined perilla oil was increased with dose-dependent fashion in concentration of the black rice extracts. Among several extracts tested, 80% aqueous methanol extract showed the highest antioxidative activity, followed by hexane, chloroform, in that order. The peroxide value and TBA value for their antioxidation stability were also lower than that of control. This result was similar to that of AOM test.

Mixed feeds and their components are a very diverse matrix compared to other agricultural products worked on with NIRS classically. On a database of mixed feeds and their components (n=2.500) universal PLS calibrations and “local” calibrations were compared. The results from validation (n=600) show the potential of the calibrations and their limitations. Crude protein, crude fiber, crude fat, sugar and starch are predicted with SEPs of 0.6%, 1%, 0.3%, 1% and 1.5%, respectively. Ash content of 15% and more in several mixed feeds or components as well as rare components limit the use of NIRS for routine analyses.

Baked black soybean has great nutritional value, so it is a great potential ingredient in cake. To find an acceptable ingredient ratio, baked black soybean powder was to wheat flour in different experimental groups. The control was pure wheat flour, and the experimental groups had 0 (control), 10%, 20%, 30%, and 40% baked black soybean powder added. The baked black soybean powder consists of moisture (4.88%), crude protein (34.46%), crude fat (11.35%), crude ash (4.84%), and carbohydrates (44.47%). The specific gravity, spreadability, and baking loss increased with an increase in the amount of baked black soybean powder, but specific volume decreased. The 'L' and 'b' chromaticity values of a sponge cake decrease with increased amounts of added baked black soybean powder. The texture becomes more hard and stuff with added baked black soybean powder, but springiness decreases. A sensory test found the best experimental group to be that of 20% powder added.

The quality characteristics of doenjang which contained Astragalus membranaceus water extracts were investigated in this study. The contents of moisture, crude protein, and crude fat were not significantly different in the doenjang which contained Astragalus membranaceus water extracts. The crude ash content was significantly higher in the doenjang which contained Astragalus membranaceus water extracts. The doenjang which contained Astragalus membranaceus water extracts showed higher a-value. Antioxidative activity was evaluated by using the thiobarbituric acid reaction products assay and peroxide value. Antioxidative activity and hydrogen donating activity were increased in doenjang which contained Astragalus membranaceus water extracts. Doenjang which contained Astragalus membranaceus water extracts showed no differences with traditional doenjang in sensory profiles of taste, color, flavor, and overall quality. These result showed the applicability and higher quality of doenjang which contained Astragalus membranaceus water extracts.
