장 건강에 유익한 프리바이오틱스 소재를 개발하기 위하여 배변을 촉진하는 효능을 지닌 붉은팥을 식품 발효에 이용되는 Bacillus subtilis KCCM 11965P로 발효하여 다음과 같은 결과를 얻었다. 붉은팥의 일반성분은 회분 3.35±0.04%, 조단백질 21.1±0.19%, 조지방 0.35±0.02% 함 유되었다. 붉은팥 원물 1%, 3%, 5%와 Bacillus subtilis KCCM 11965P 3% (v/v)를 접종하여 0, 24, 48, 72시간 배양 하였다. 배양액의 총균수를 측정한 결과 붉은팥 원물을 3% 첨가한 후 72시간 배양군에서 Bacillus subtilis KCCM 11965P 발효가 가장 적합하였다. 발효 시간에 증가함에 따라 총 폴리페놀 함량과 DPPH 라디칼 소거활성이 증가하였다. Protease 활성은 붉은팥 원물 5% 첨가한 후 72시간 배양한 군(2.69±0.003 unit/mL)에서 활성이 가장 높았다. 발효시간과 붉은팥 원물 첨가 농도가 증가함에 따라 α -amylase 활성도 증가하였으며, 붉은팥 원물 5% 첨가한 후 72시간 배양한 군에서 0시간 배양군(1.0±0.1 unit/mL) 보다 26.0±0.2 unit/mL로 증가하였다. Bacillus subtilis KCCM 11965P로 72시간 배양한 후 유리아미노산을 측정한 결과 leucine은 붉은팥 원물 5% 첨가한 0시간 배양군 5.22 mg/L 에서 67.59 mg/L로 증가하였으며, 비필수아미노산인 tyrosine은 5% 첨가 0시간 배양군 10.08 mg/L에서 259.35 mg/L로 증가하였다. 이와 같이 Bacillus subtilis KCCM 11965P로 붉은팥을 발효하면 항산화 활성, protease 효소활성, 및 α-amylase 효소 활성이 증가하였으며, 유리아미노 산과 유기산이 증가하였다. 붉은팥을 발효하는데 Bacillus subtilis KCCM 11965P가 적합할 것으로 판단되며, 붉은팥은 프로바이오틱스를 활성화시켜 장 건강을 증진시킬 수 있는 프리바이오틱스 소재로 개발할 수 있는 가능성을 시사 하였다.

“Jokyoung”, a new bread making wheat cultivar, was developed from the cross between “Seri 82”, a hard white wheat from CIMMYT, Mexico and “Keumkang”, a hard white wheat with high milling rate and early maturing from Korea by National Institute of Crop Sci

This study was carried out to investigate the difference of growth characteristics, yield and extract content between upland and paddy ginseng cultured with 4­year-old ginseng in 2003. Although upland ginseng showed larger variation in yield than that of paddy ginseng, the average of it was greater than that of paddy ginseng because it showed better growth of aerial part and higher survival rate than that of paddy ginseng. Moisture content of fresh root was 71.8~%~;(68.5~~73.1~%),~;and~;72.7~%~;(70.2 ~~74.9~%) on average in upland and paddy ginseng, respectively. Paddy ginseng showed higher hardness in taproot, and higher rate of rusty colored root than that of upland ginseng. The ratio of taproot dry weight in upland ginseng was smaller than that of paddy ginseng, while that of lateral root was larger in upland ginseng. Ratio of marketable root (>60g) to total harvested roots was 13.7~%~;(0.82~~8.0~%)~;and~;7.7~%~;(1.6~~12.6~%) in upland and paddy ginseng, respectively. Extract content did not show distinct difference between upland and paddy ginseng, but it showed large variation from 16.1~;to~;25.1~% in taproot, and from 24.2~;to~;32.5~% in lateral root depanding on the ginseng field examined.

"Seolhyangchalbyeo", an aromatic and glutinous rice cultivar, was developed by the rice breeding team of National Crop Experiment Station, RDA during the period from 1991 to 1999 and released in 2000. The cultivar is derived from a cross between Miyagaori

“Joeun” is a new semi - hard wheat variety with early maturity and good milling quality. It was developed from a cross between “Eunpamil” and “Suwon 242” at the National Crop Experiment Station, RDA. “Eunpamil” as a female parent was medium in plant heigh
