The purpose of this study was to investigate the effect of the addition of various concentrations of sea mustard powder on the quality characteristics of Bacsulgi. The sea mustard powder was added to rice powder at ratios of 3, 5, 7, and 9%(w/w). The moisture contents and salinity of Bacsulgi were increased with the addition of sea mustard powder. The incorporation of sea mustard powder in Bacsulgi lowered the lightness values but increased the blueness and yellowness values. Rheology test showed that hardness was significantly (p<0.05) decreased with increasing sea mustard powder content. The springiness and cohesiveness were decreased, whereas the adhesiveness was increased, with increasing sea mustard powder content. Scanning electron microscopy showed that the size of the air cells increased and the surface of rice powder swelled with increasing sea mustard powder content. The result of sensory evaluation showed that there were significant (p<0.05) differences in the scores of smell and taste sensory characteristics among the samples. The overall eating quality was the highest in the control and decreased with increasing sea mustard powder level. The study results suggested that Bacsulgi prepared with up to 5% addition of sea mustard powder was as acceptable as Bacsulgi prepared without sea mustard powder.

This study was undertaken to examine the effect of sea tangle and sea mustard on physiochemical and sensory characteristics of cakes and the possibility commercialization of these functional cakes. The moisture contents of cakes prepared with sea tangle and sea mustard were higher than those of control, and a positive correlation between water holding capacity(WHC) and moisture contents was observed(r=0.836). As addition level of sea tangle and sea mustard was increased, volume of cakes were decreased, whereas hardness was increased slightly and color became deep. Hardness was strongly correlated to the volume of cakes(r= 0.914). Visual observation by photomicrography showed that, as addition level of sea mustard and sea tangle was increased, formation of air cells were prohibited and thus volume of cakes was decreased. The microstructural observation by scanning electron microscopy(SEM) showed that air cells of cakes were well developed up to 5% addition of sea tangle powder. As a result of the sensory evaluation for the cakes prepared with sea tangle and sea mustard, no significant difference was observed between control and those addition levels up to 5%. Flavor was proved to be the most important factor in determining overall acceptability and hedonic hardness score was inversely correlated to the objective hardness value(r= 0.853).

This study was conducted to investigate the effect of various types of calcium sources on calcium metabolism. Sprague-Dawley male rate weighing approximately 82g were divided into 6 groups and fed experimental diets containing about 0.2% calcium for 4 weeks. Perilla leaves, dried sea mustard, mulberry leaves, loach, skim milk powder, and CaCO3 were used as calcium sources for this study. Food intake of experimental groups showed no significant difference from that of control group, but food efficiency ratio were higher in group fed loach as a calcium source. Apparent calcium absorption from perilla leaves, and skim milk powder groups as good as that in CaCO group. Femur length showed no significant difference among exjerimental groups with different calcium sources. The breaking force of bone was higher in loach and dried sea mustard groups. Weight, ash weight, and calcium content of the femur were higher in the loach diet group than in the others. Thus, calcium from not only skim milk powder but also perilla leaves, dried sea mustard, mulberry leaves, and loach appears readily available and all of these can be recommended as calcium sources.

This study investigated the inhibitory effects of sea mustard on high-fat diet-induced obesity and hyperlipidemia in Sprague-Dawley rats. Sea mustard (Undaria pinnatifida) powder, sea mustard ethanol extract, and sea mustard ethanol-extracted residue were tested. The ethanol extracted residue had the most beneficial anti-hyperlipidemic activity. Alginate in the sea mustard was considered to be the key component. The ethanol-extracted residue of sea mustard also had antioxidant activity, which may be effective in preventing hyperlipidemia by increasing the enzymatic activity of superoxide dismutase, which can remove active oxygen from the bloodstream.

Various bacterial strains were isolated from rice field ditch water, and their seaweed degrading activities were investigated. They were incubated in a liquid medium of sea tangle (Laminaria iaponica) and sea mustard (Undaria pinnatifida) powder for 3 weeks. Ratios of reduced sugar to total sugar of the liquid medium were measured once a week. Ratios of reduced sugar to total sugar of 27A311, 27C221 27A111 and 27B121 strains were highest. Accordingly, these four strains were incubated in 3 different liquid media of sodium alginate, sea tangle powder, and sea mustard powder for 3 or 4 weeks. The ratios of reduced sugar to total sugar and cell growth were measured once a week. Cell growth was higher in 27A111 and 27C221. Ratios of reduced sugar to total sugar was higher for 27C221 in the liquid mediums with sodium alginate and sea mustard powder, and for 27A111 in the liquid medium with sea tangle powder.

Contents of insoluble(IDF), soluble dietary fiber (SDF), and total dietary fiber(TDF) of 30 foods which are consumed commonly by 80 Koeran male college students were determined by Prosky and colleagues' enzymatic-gravimentric method. Foods with highest intake frequency were rice, Kimch'i, and red pepper powder. TDF, IDF, and SDF contents of rice were 0.96, 0.59 and 0.37g/100g wet wt., respectively and tose of Kimch'i were 3.07, 2.19 and 0.88g/100g wet wt., respectively. Red pepper powder contained high amount of TDF(39.37) and IDF (33.13g/100g wet wt.). The TDF content of the 30 foods ranged from 0.70 to 39.37g/100g wet wt. Red pepper (39.37), dried laver(31.36), and dried sea mustard (37.77g/100g wet wt.) contained high amounts of TDF. The IDF content of the 30 foods ranged from 0.13 to 33.13g/100g wet wt. Red pepper powder (33.13), dried laver(15.55) and sesame(15.43g/100g wet wt.) contained high amounts of IDF. SDF of the 30 foods ranged from 0.01 to 25.66g/100g wet wt. Dried sea mustard(25.66), dried laver(15.81), coffee powder (13.17), and garlic(8.72g/100g wet wt.) were good sources of SDF. % ratio of SDF to TDF of the 30 foods was lower than 50% except soybean curd(94.27%), coffee powder (88.93%), garlic(86.17%), dried sea mustard(67.94%), and dried laver(50.41%). It is recommended to increase intake of seaweeds in order to supply TDF adn SDF properly.

우리나라에서 소비량인 높은 대표적인 해조류인 김, 미역, 다시마 및 톳을 이용하여 추출물을 제조하여 추출물의 추출수율, 색도, 총 페놀 함량, DPPH 라디칼 소거능 및 ABTS 라디칼 소거능을 분석하였고, 추출물의 지질산화 억제능 및 tyrosinase 억제활성을 분석하였다. 용매를 이용하여 김, 미역 다시마 및 톳의 추출물 수율은 3.00, 5.38, 11.73 및 0.72%를 나타내었고, 색도 분석 결과 김, 미역, 다시마 및 톳 추출물의 명도는 82.88, 78.53, 83.04 및 78.11로 다시마 추출물의 명도가 가장 밝은 것으로 나타났으나 김 추출물의 명도와 유의적 차이는 나타나지 않았다. 총 페놀 함량은 김, 미역, 다시마 및 톳 추출물이 각각 42.23, 11.59, 10.09 및 46.59 mg/g으로 나타냈다. DPPH 라디칼의 경우 톳 추출물이 82.43%로 가장 높은 라디칼 소거능을 나타냈으며 김 추출물의 경우 26.76%의 라디칼 소거능을 확인하였다. ABTS 라디칼 소거능의 경우 DPPH 라디칼 소거능 결과와 유사한 경향을 나타내었다. 또한 해조류 추출물의 tyrosinase inhibition effect 결과는 김, 미역, 다시마 및 톳 추출물의 tyrosinase inhibition이 각각 25.93, 26.32, 24.76 및 20.24%의 활성을 나타냈으며 유의적인 차이는 나타내지 않는 것으로 확인하였다. 해조류 추출물의 총 페놀화합물, DPPH 라디칼 소거능, ABTS 라디칼 소거능 및 미백활성에 대한 상관분석 결과 해조류 추출물의 총 페놀 함량은 DPPH 및 ABTS 라디칼 소거능의 결과 값과 P<0.001 수준에서 유의적으로 상관관계를 나타내는 것으로 확인되었다.
