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 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.

To investigate the optimum conditions of seaweed Mooks prepared with sea mustard (Indaria pinnatifida) and sea tangel(Laminaria japonica), pH, viscosity , yield and jelly strength were studied on the sol and /or gel (Mook ) made from homogenized seaweeds. Solubilization conditions of homogenized seaweeds were heating at $65^{\circ}C$ for one hour after mixing homogenized seaweed with 1 % $K_2$HPO$_4$ by 1 ; 1 (v/v) . Gelation conditions were 24 hrs by natural permeation of Ca++ into the sol in three times (v/v) of 1 % CaCl$_2$ solution to solubilized seaweed passed through 60 mesh of sieve. There are generally no relationship between viscosity of solubilized seaweed and jelly strength of Mook produced by gelation of the sol in CaCl$_2$ solution . Jelly strength of sea mustard Mook was more than 500g/$\textrm{cm}^2$ , yield was 87.5% of the solubilized and filtrated seaweed . Jelly strength and specific gravity of sea tangle Mook were higher those of sea mustard Mook, while its yield was lower than that of sea mustard Mook.

The antimutagenic and cancer cell growth inhibitory effects of methanol extracts from 9 kinds of seaweed were studied in the Ames assay and cell culture systems, respectively. The methanol extracts from the seaweeds of sea lettuce, chlorella, sea tangle, sea mustard, sporophyll of sea mustard, fusiforme, seaweed papulosa, purple laver and ceylon moss showed antimutagenicities against aflatoxin B₁(AFB₁) and N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in the Salmonella typhimurium TA100. These extracts revealed relatively higher antimutagenicity against AFB₁(indirect mutagen) than MNNG(direct mutagen). Sporophyll of sea mustard and seaweed papulosa exhibited strong antimutagenic activity against AFB₁, and sporophyll of sea mustard, sea tangle and ceylon moss also reduced the mutagenicity induced by MNNG. The sporophyll fo sea mustard exerted the highest antimutagenic activity among the samples treated. The methanol extracts from 9 kinds of seaweed inhibited the growth of two cancer cell lines, AGS human gastric adenocarcinoma cells and HT-29 human colon carcinoma cells. Sea tangle, sea mustard and sporophyll of sea mustard inhibited the growth of cancer cells significantly. These results suggest that various seaweeds show not only antimutagenic activity but also growth inhibitory effect of some cancer cells.

This study was performed to investigate some quality characteristics of 새려 prepared from soybean milk and various seaweed(Undaria pinnatifida, Laminaria japonica, Porpyra tenera, Enteromorpha sp., Codium sp.) pulps in the ration of 9:1(v:v) with 20% MgCl2. The yields of tofu containing Undaria pinnatifida, Laminaria japonica, or Enteromorpha sp. increased but porphyra tenera, Codium sp. decreased in comparison with tofu prepared from whole soybean milk. The protein content of tofu containing Undaria pinnatifida, Laminaria japonica, Porphyra tenera, or Codium sp. increased but Enteromprpha sp. decreased in comparison with the tofu prepared from whole soybean milk. The content of Ca in Undaria pinnatifida, Porphyra tenera added tofu was higher than that of the tofu prepared from whole soybean milk or other seaweeds added tofu. In sensory evaluation the texture, color, taste of tofu were favored with the addition of sea mustard(Undaria pinnatifida) pulp than that of the tofu prepared from whole soybean milk or tofu prepared other seaweed. Tofu prepared was possible with adding 0.5~1.5% sea mustard to soybean milk but the feasible added amount level was 1% of sea mustard. The yields, protein Ca, and K content of tofu were increased by the more adding amount of sea mustard tan tat of the tofu prepared from whole soybean milk. The hardness values of 1% sea mustard added tofu were decreased than that of the tofu prepared from whole soybean milk ; on the other hand, elasticity, cohensiveness, gumminess and brittleness of tofu with sea mustard increased. The L and a values of tofu were lower and b values were higher with the addition of 1% sea mustard. The content of histidine, tyrosine, leusine, and phenylalanine were decreased but the other amino acid were increased in tofu prepared from 1% sea mustard pulp added to soybean milk. The saturated fatty acid and monoene fatty acid content of tofu were increased and C18:2, C18:3(${\gamma}$), C18:3, C20:5 of polyene fatty acid were slightly decreased in tofu prepared from 1% sea mustard pulp added to soybean milk.

The modulating effect of feeding sea mustard (Undarina pinnatifida), a fiber-rich seaweed, during initiation and post-initiation phases of colon carcinogenesis was investigated in Sprague Dawley rats. Four groups of animals were exposed to the two weekly injections of a chemical carcinogen, azoxymethane (AOM). Animals were placed on diet containing 15% sea mustard during initiation. post-initiation or initiation+post-initiation phase of carcinogenesis for 10 weeks, and colonic aberrant crypt formation and cell proliferation were compared to those of rats fed semi-synthetic control diet. Results showed that sea mustard feeding significantly reduced the numbers of both aberrant crypts and aberrant crypt foci. Also, labeling indices and proliferation zones were significantly reduced in the colon of the rats fed sea mustard diets. These results indicate that the diet containing sea mustard may decrease the risk of colon cancer development, and a part of such effect may be mediated through both the blocking of initiation and the suppression of cell proliferation in the colonic crypts, although precise mechanisms should be further examined.
