심해성 붉은 대게(Chinoecetes japonicus)의 증자 가열에 의한 감량, 수율, 품질조사와 건조처리에 따른 유리아미노산의 함량을 분석·고찰하였다. 증자처리에 따른 감량 변화는 20.48~26.72% 범위로 통게 중량이 클수록 감소율이 적었으며 수작업에 의한 선육 수율은증자처리구가 생시료 선육 수율보다 유의성 있게 높았다.(P<0.05) 증자, 건조처리에 따라 pH 는 약간 상승하였으며 몸통육이 다리육보다 높은 수치를 보였다. VBN치는 감압건조처리구에서 높은 수준을 나타내며 다른 처리구에서는 l0mg% 내외의 수준이었다. TMAO 성분은 생다리육 및 몸통육에서 각각 98.13mg% 와 101.13mg% 였고, TMA 함량을 감압건조시료에서 높게 검출되었다. 유리아미노산 및 아미노산 유도체 물질이 30여종 분석되었으며 다리육의 함량 변화는 감압건조처리구가 높은 감소를 보이고 동결건조처리구에서 적은 감소를 보였다. 주요 아미노산은 glutamic acid 외 5종으로 총 유리아미노산의 39.94%를 차지하였다. 몸통육 중의 유리아미노산 함량은 다리육보다 함량이 낮았으며 주요 아미노산 함량비는 46.78% 정도이고 정미성 아미노산은 동결처리구가 높고 열풍건조처리구가 낮게 나타내었다.
D-xylan은 최근 대체 에너지원인 알콜 생산의 기질로서 주목받고 있을 뿐만 아니라 butanol과 butandiol과 같은 유기 용매와 xylitol과 같은 감미료, xylooligosaccharide와 같은 bifidogenic factor 등의 원료로 사용된다. 본 논문에서는 발효된 톱밥으로부터 xylanase 강력 생산성 균주를 분리하고 제 특성을 확인하여 Bacillus sp. GS로 동정하였다. Xylanase 생산성을 높이기 위해 효소 생산 배지 성분과 배양 조건을 최적화 하였는데, 각각 xylan 1.25%, yeast extract 0.1%, NaNO_3 1.2%, K_2HPO_4 0.1%, MgSO_4 0.02%, mineral salt 0.005%와 pH 6.5, 배양 온도 37℃였다.
This study was conducted a comprehensive sarvey of 39 elementary schools operating school lunch program in Seoul area. The purpose of this study was to investigate the realities of school lunch program. This method of this research was based on the interview survey with dietitian working at each school with prepared questionaire. The survey was conducted for 16 days from Dec. 5 to Dec. 20., 1990. The results of this study were as follows ; (1) The average numbers of children supplied with food were 1, 244 for each school. It was about 44.3% of the students enrolled in the school. The average feeding cost was 738 won per a child for a day. (2) Only one school was operating nutritional education as a regular educational program, and others were operating nutritional education off and on. (3) All nutrient intake except energy were higher than the RDA for school lunch program. (4) The ratio of animal food was 46.2%, and that of vegetable food was 53.8%. (5) The ratio of schools without sterilizer cabinet came to 56.4%, and that of schools without warmer was 97.4%. (6) The facilities for drainage, lighting, ventilation, anti-rat of a cookery were comparatively good.
This study was divised to observe an inhibitory toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG : Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol precipitate component of large root NPG(mean 46.8%) was higher (mean 1.8 times) than that of water extract component in final reaction concentration ; 500㎍/㎖, on the other side inhibitory effect of water extract component in small root NPG (mean 43.9%) was higher(mean 1.2 times) than that of ethanol precipitate component, respectively. In a way inhibitory effect of ethanol precipitate component in large root NPG(47.6%), when final reaction concentration of sample were l, 000㎍/㎖, was about 40% lower than that of Korean red ginseng, respectively.
