Acceptable fish noodles of better nutritional and sensory values than conventional noodle made only wheat flour were prepared by mixing wheat flour and ground tile fish (Branchioste gus japonicus). In oder to mask a distinctive fish odor, various herbs and spices, such as ginger (Zingiber officinale), curry (Chalcas koenigii), nutmeg (Myristica Pagrans), garlic (Ailium sativum), black pepper (Piper nigrum), lemon (Cirtus limon) or sodachi (Citrus sudachi) were added to the basic tile fish noodle. Also, for the purpose of enhancing eating qual ify and nutritional value of basic noodle were combined some agricultural or fishery products of Cheju island, citrus fruits; danyooja (Citrus danyooga), hagul (C. natfudaidai), medical plants; angelica utilis (Angelica keiskei), ginseng (Panax ginseng), cactus (Opuntia dillenii), vegetable; carrot (Daucus carota), dropwort (Oenanthe jnvanica), seaweeds; fusiforme (Hizkia fusiforme), gulfweed (Sargaceae hlvelium). The optimal mixing ratio for preparing the basic tile fish noodle amounted to ground tile fish 135 g: tile fish stock 139 $m\ell$: wheat flour 450 g: salts 10 g. The mixture of curry powder (2.5 g) and nutmeg powder (2.5 g) was proved to be the most effective combinations for masking unfavorable fish odor. The optimal amounts of materials to be added to the prepared basic noodle were 25 g citrus zest and 80m1 citrus juice for citrus fruits noodles, and ca. 140 g puree for noodles from medical plants, vegetables and seaweeds, respectively. The preference score obtained from consumer preference test, on a 9-point scales, were in oder of i) danyooja > carrot, angelica, ginseng > fusiforme, ii) hagul > dropwort, cactus > gulfweed. The shelf-life of tile fish noodle based on bacterial counting was estimated to be 7-days at 5$^{\circ}C$.

Physicochemical properties and mineral compositions of seaweed salts prepared with various seaweeds and concentrated sea water were determined. Ash content of sea mustard was highest (22.7%) and that of laver the lowest (9.8%). Sea mustard contained high amount of Na, while sea tangle and seaweed fusiforme contained high amounts of K and Ca. When insoluble solids were removed after incineration of dried salt, surface color of the salt whitened more due to increase in salt purity with resulting decreases in pH and oxidation-reduction potential (ORP), pH and ORP of the ashed salt decreased, and K and Ca contents increased, while Mg content decreased. Yield of seaweed salt was the highest in sea mustard, ORP was lowest in sea tangle and seaweed fusiforme, and K and Ca contents increased significantly in sea tangle and seaweed fusiforme salts. As the concentration of sea water increased, yield and purity of the salts increased with decrease in pH and ORP and increase in Ca and Mg contents. Seaweed salt showed the characteristic crystalline structure as viewed by SEM.

This study was conducted to investigate alterations of seaweed composition upon Lactobacillus rhamnosus GG (LGG) fermentation as well as potential anti-inflammatory effects and mechanism (s) of water extracts and fermented water extracts of Laminaria japonica (LJ) and Hizikia fusiforme (HF) in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Total polyphenol, total sugar, and reducing sugar contents were measured in LJ and HF water extracts before and after fermentation by LGG. Alterations of inflammatory cytokine levels in cell culture media were measured by ELISA, and levels of phosphorylation of c-jun NH2-terminalkinase (JNK) and extra cellular signal regulated kinase (ERK) were examined by Western blot analysis. LGG fermentation of LJ and HF altered total polyphenol and sugar contents in water extracts of LJ and HF. LPS-induced production of pro-inflammatory cytokines such as IL-6 and $TNF-{\alpha}$ was significantly reduced by HF-f compared to control in RAW264.7 cells. Consistent with reduction of anti-inflammatory cytokine, interleukin (IL)-6, and tumor necrosis factor $(TNF)-{\alpha}$ levels by HF-f, HF-f also significantly reduced phosphorylation of ERK and JNK in LPS-stimulated RAW264.7 cells. In addition, LJ-f and HF also significantly reduced phosphorylation of JNK and ERK induced by LPS in RAW264.7 cells. Overall, our result suggests that HF-f among the four tested seaweed extracts is the most potent anti-inflammatory agent, and its mechanism of action is partially mediated by reduction of JNK and ERK phosphorylation as well as IL-6 and $TNF-{\alpha}$ production in LPS-stimulated RAW264.7 cells.

The edible sargasso seaweed hijiki Sargassum fusiforme is known to have high concentration of arsenic, which is a threat to human health, particularly due to inorganic arsenic. In this study, various methods were used to remove inorganic arsenic from steamed hijiki concentrate. The highest concentration of arsenate [As(V)] in both raw and processed hijiki during steamed hijiki manufacturing process was within the range of 8.213-14.356 mg/kg, and it is a potential source of inorganic arsenic, which can result in re-contamination and cause environmental pollution. The removal efficiencies of the various removal methods were within the range of 57.3-83.4%, and 19.0% reduction was achieved using activated carbon and alginate bead. Further, activated carbon showed the best adsorption effect of inorganic arsenic. Therefore, we suggest that activated carbon is a suitable efficient method for removing inorganic arsenic and has low operational costs in field applicability.

The anticancer and immunomodulatory activities of low molecular weight (Mw 11 kDa) fucoidan isolated from Hizikia fusiforme (H. fusiforme) via the ultrasonification extraction process were assessed in this study. Low molecular weight fucoidan improved the growth of human B and T cells, up to approximately 40% as compared to the controls (untreated) and 30% for commercially available fucoidan (Mw 150 kDa). IL-6 and TNF-$\alpha$ were secreted from human B cells at levels of $7.8\times10^{-4}$ pg/mL and $7.2\times10^{-4}$ pg/mL, respectively, and these levels were higher than the levels measured in the controls and with other high molecular weight fucoidan. It was also determined that the cytokine from human B and T cells cultivated with added fucoidan enhanced the growth of human NK cells. The fucoidan isolated from H. fusiforme showed low cytotoxicity, approximately 19%, after the addition of 1.0 mg/mL, the highest tested concentration. The growth of human lung cancer cells (A549) and human breast cancer cells (MCF-7) were inhibited by 69.8% and 83.3%, respectively. These results demonstrated that the low molecular weight fucoidan isolated from H. fusiforme has potential as a new functional food component that evidences immunomodulatory activities and anticancer activity. One of the primary positive features of this fucoidan is that low molecular weight polysaccharides can be readily handled during processing.

This study was conducted to investigate the effects of brown seaweed (Undaria pinnatifida) by-product and seaweed fusiforme (Hizikia fusiformis) by-product supplementation on growth performance and blood profiles including serum immunoglobulin (Ig) in broilers. Fermentation of seaweeds was conducted by Bacillus subtilis and Aspergillus oryzae. In a 5-wk feeding trial, 750 one-d-old broiler chicks were divided into 5 groups, and were assigned to the control diet or experimental diets including control+0.5% brown seaweed (BS) by-product, control+0.5% seaweed fusiforme (SF) by-product, control+0.5% fermented brown seaweed (FBS) by-product, and control+0.5% fermented seaweed fusiforme (FSF) by-product. As a consequence, body weight gain (BWG) and gain:feed of seaweed by-product groups were clearly higher, when compared to those of control diet group from d 18 to 35 and the entire experimental period (p<0.05). In mortality rate, seaweed by-product groups were significantly lower when compared to control diet group during entire experimental period (p<0.05). However, Feed Intake of experimental diets group was not different from that of the control group during the entire experimental period. Whereas, Feed Intake of fermented seaweed by-product groups was lower than that of non-fermented seaweed groups (p<0.05). Total organ weights, lipids, and glutamic oxalacetic transaminase (GOT) of all treatment groups were not different from those of control group. However, glutamic pyruvate transaminase (GPT) of all treatment groups was higher than that of control group at d 17 (p<0.05). In case of serum Igs concentration, the concentration of IgA antibody in BS, SF, FSF treatment groups was significantly higher than in control group at d 35 (p<0.01). IgA concentration in FBS supplementation groups was negligibly decreased when compared to the control group. IgM concentration in the serums of all treatment groups was significantly higher than in control group (p<0.05) and in fermented seaweed by-product groups were much higher than in non-fermented seaweed groups (p<0.05). On the other hand, IgG concentrations in all treatment groups were lower than in control group (p<0.05). Taken together, our results suggest that by-product dietary supplementation of BS, SF, FBS, and FSF in poultry may provide positive effects of growth performance and immune response.

Extraction yields of Hizikia fusiforme and Aloe vera Linne by supercritical carbon dioxide($SC-CO_{2}$) with and without ethanol as a cosolvent, and antimicrobial activities of the extracts against Escherichia coli, Bacillus subtilis, Saccharomyces cerevisiae and Alternaria sp. were determined. Both yield and solubility of the extracts from Hizikia fusiforme and Aloe vera Linne by $SC-CO_{2}$ with ethanol were two times greater than those by only $SC-CO_{2}$. All of the extracts demonstrated antimicrobial activities in the decreasing order of bacteria, yeast and fungus. The extracts by $SC-CO_{2}$ with ethanol showed almost the same degree of microbial growth inhibition as those by only $SC-CO_{2}$. Based upon these data, it was speculated that the components soluble in nonpolar solvent might be more responsible for the antimicrobial activity.

The physiological properties of extracts from Hizikia fusiforme with different extraction methods (hot water extraction, autoclave extraction and high pressure extraction) were investigated. The amounts of substances related to polyphenol and flavonoids contents were the highest in autoclave extract (30.51 mg/g and 4.78 mg/g, respectively). The DPPH radical scavenging activity was the highest in the autoclave extract (81.80%) at the 5 mg/mL. Autoclave extract exhibited the strongest ABTS radical scavenging activity and reducing power among the three extraction methods. However, ferrous ion chelating, TBA reactive substances and xanthine oxidase inhibition activity of high pressure extract were higher than those of the other extracts. Additionally, the tyrosinase and elastase inhibition activities of high pressure extract with a concentration of 1 mg/mL were higher than those of the other extracts. These results suggest that extracts of Hizikia fusiforme have a potential to act as functional materials, and autoclave and high pressure extractions are superior to hot water extraction for enhancement of the biological activity.

An 80% ethanol extract of Hizikia fusiforme was obtained and followed by successive fractionation using the organic solvents n-hexane, ethyl acetate, and n-butanol to identify the antioxidative substance. The aqueous part of the nbutanol fractionation step, showing high antioxidative activity, was subjected to reverse-phase liquid chromatography. As a result, a substance purified from a BB-2 fraction showed high antioxidative activity. The m/z 419 [M+H] molecular ion peak in the fraction was observed by the analysis of the ESI-LC/MS spectrum. By the analysis of 1H NMR (500 MHz, DMSO-$d_6$) and $^{13}C$ NMR (125 MHz, DMSO-$d_6$) spectra, a unique compound of the fraction was biochemically identified as a 5-hydroxy-3,6,7,8,3',4'-hexamethoxyflavone (5HHMF). We also investigated the effect of 5HHMF on human gastric AGS carcinoma cells. Western blot analysis suggested that the flavone substantially increased the levels of the death receptor-associated apoptosis mediators Fas, Fas L, FADD, TRADD, and DR4 in a concentration-dependent manner. The levels of Fas, Fas L, TRADD, and DR4 in the cells treated with 5HHMF ($5{\mu}g/ml$) were approximately 26.4-, 12.8-, 6.7-, and 9.8-times higher than those of non-treated cells, respectively. Of note, the level of FADD protein in the cells exposed to 5HHMF ($1{\mu}g/ml$) increased approximately 9.6-times. In addition, the cleavage of caspase-3, -8, and -9 in cultured AGS cells treated with 5HHMF was significantly confirmed. Therefore, our results suggest that 5HHMF from H. fusiforme is involved in the induction of death receptor-associated apoptosis mediators in human gastric AGS carcinoma cells.

Uronate compositions and molecular weights of alginates from the four kinds of brown algae, sea mustard (Undaria pinnatifida), sea tangle (Laminaria japonica), gulf weed (Sargassum fulvellum), and seaweed fusiforme (Hizikia fusiforme), in regard with the harvesting season were investigated. Sea mustard contained the highest amount of alginates in the four kinds of brown algae. D-Mannuronic acid to L-guluronic acid (M/C) ratio of the alginates was high in order of seaweed fusiforme, gulf weed, sea mustard, and sea tangle, and especially in water-soluble alginate. Molecular weights of the alginates were greater with the growing period ranging in $4,500\~4,800\;kDa$ for sea tangle, $4,000\~4,200\;kDa$ for sea mustard, $3,300\~3,400\;kDa$ for seaweed fusiforme, and $3,000\~3,200\;kDa$ for gulfweed. In water-soluble alginate of sea mustard, M/G ratio was much higher in sporophyll than in midrib and blade.
