  • We investigated the effects of both $CaCl_2$ treatment and modified atmosphere packaging (MAP) (compared with non-packaging on 'Fuji' apples from the Young-Joo region of Korea. Apples were dined into 5% (w/v) $CaCl_2$ solution for 15 min and then packaged with or without LDPE film (thickness: 0.025 mm) before cold storage at $0^{\circ}C$. Weight loss of applies in film packaging was lower than that of non-packaging applies, and the apple firmness resulting from $CaCl_2$ treatment and MAP was better than that of apples receiving control treatment. Also, $CaCl_2$ treatment and MAP resulted in improvements in titratable acidity, soluble solid content (SSC), and decay rate compared to control treatments. However, no significant differences in vitamin C content were found amongst apples receiving various treatment. the results suggest that a combination of postharvest calcium dipping and plastic film packaging may effectively preserve 'Fuji' apples, and that the combined treatment are better than either individual treatment.

  • We investigated the effect of moisturizing and anti-oxidation of Astragalus membranaceus (Astragali Radix) root extract with respective to growing districts and extract methods for the purpose of development of cosmetic ingredients. Astragalii Radix was collected in Jecheon, Jeongseon, Taebaek, and Yeongju in Korea and China as growing districts. Formononetin was determinated by HPLC method as one of the various active agents in Astragalus membranaceus root extract. The 75% ethanol extract demonstrated to be more effective than $H_2O$-extracted one for a scavenging activities to DPPH radicals and reactive oxygens. The 75% ethanol extract showed $IC_{50}$ (50% scavenging concentration) of 2.162 mg/mL and 2.981 mg/mL in case of free radical scavenging activity test and reactive oxygen scavenging activity test, respectively Especially, free radical scavenging activity of isoflavonoids isolated from ethylacetate fraction was similar to scavenging activity of genistein. Astragalus membranaceus root extract of Jecheon district by sonicating extraction method was more effective in skin hydration compared with others.

  • Sesame samples used in this study were Korean variety cultivated in Chochiwon City of Korea (KvKc), Chinese variety cultivated in Jilin Province of China(CvCc), Chinese variety cultivated in Chochiwon city of Korea(CvKc) and Korean variety cultivated in Jilin Province of China(KvCc). The extraction yields of sesame oils from KvKc, CvCc, CvKc and KvCc were 47.8%, 48.1%, 48.6% and 49.3% respectively. The color value (L value) of sesame oil from KvKc was lower than that of CvCc and KvKc sesame oil showed dark brown color. The composition of neutral lipid, glycolipid and phospholipid of free lipids from KvKc and U sesame oils were 93.1%, 6.6%, 0.2% and 94.7%, 4.6%, 0.8% respectively. Major fatty acids of KvKc and CvCc sesame were usaturated fatty acids, such as oleic and linoleic acid. Total composition of the two major fatty acids of KvKc was 84.6% which was almost same with that of CvCc. However the composition of oleic and linoleic acid of KvKc were 47.1% and 37.5%, while the composition of CvCc were 40.5% and 44.3%. When cross-cultivated, the composition of oleic and linoleic acid of CvKc were 41.0% and 43.5%, while the composition of KvCc were 42.0% and 43.7%. The contents of total amino acids and essential amino acids of KvKc were 713 mg% and 309 mg%, which were much higher than those of CvCc. When cross-cultivated, the content of total amino acids of KvCc was 44% lower than that of KvKc while the content of total amino acids of CvKc was 36% higher than that of CvCc.

  • 지상파DMB 서비스가 12월 1일을 기점으로 상용서비스를 제공한다. KBS MBC SBS YTN DMB 한국DMB KMMB등 국내 6개 지상파DMB 사업자들은 이를 위해 시설투자, 인력채용 및 서비스 명칭 확정 등 준비에 박차를 가하고 있는 상태. 그렇지만 이들 표정이 밝지만 않다. 망구축은 물론, 이동전화 사업자 참여(를 매개로 하는 휴대폰 겸용 단말기 유통), 수익모델 창출 등 넘어야 할 산이 한둘이 아니기 때문이다. 더욱이 경쟁서비스인 위성DMB가 서비스를 제공중인 상황에서 오히려 '무료 서비스' 라는 장점이 이들의 발목을 잡고 있기도 하다.

  • To measure antioxidative activities, the various extracts from Ulmus devidiana were examined in oil emulsion. Water, ethanol, methanol and butanol were used as extract solutions. The activity oxygen species ($H_2O_2,-OH,\;KO_2$) bound the extracts for antioxidative activities were excellent. The extracts bound $Fe^{2+}$ ion and $Cu^{2+}$ ion showed effective antioxidative activities and strong chelating effects. The concentration of $Fe^{2+}$ ion and total ion in ethanol and methanol extracts from Ulmus devidiana root parts (Chinese) were higher than those of the other products. The highest superoxide dismutase-like activities showed butanol extracts from Ulmus devidiana root parts (Chinese) and water extracts from Ulmus devidiana bark parts (Korean). Electron donating abilities and nitric scavenging abilities of ethanol, methanol and butanol extracts were higher than those of water extracts. The nitrite scavenging abilities also reached the maximum at pH 1.2 and the minium at pH 6.0.
