  • This study was designed to observe the effects of the feeding of Hijikia fusiforme(Harvey) Okamura juice extract on the improvement of lipids in the serum of cholesterol-supplemented diet induced dietary hyperlipidemic rats fed experimental diets for 4 weeks. Concentration of total cholesterol and LDL-choloesterol in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholestero diet group. Concentration of HDL-cholesterol in serum was higher in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. Those in the Hijikia fusiforme juice extract group were higher than those in the cholesterol diet group. In the ration of HDL-cholesterol concentration to total cholesterol concentration, Hijikia fusiforme juice extract administration group was higher percentage than the other groups. Atherosclerotic index was lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of free cholesterol and cholesteryl ester in serum was rather lower in the Hijikia fusiforme juice extract group than the other groups. Triglyceride concentration in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of phospholipid in serum was more decreased in the Hijikia fusiforme juice extract group than in the cholesterol diet group. The activities of aspartate aminotransferase and alanine aminotransferase in serum were rather lower in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. From the avove research, the Hijikia fusiforme juice extracts were effective on the improvement of the lipid compositions in serum of high fat diet induced dietary hyperlipidemic rats.

  • Zingiber officinale and Hizikia fusiforme(sea weed fusiforme) have long been used for food sources in Korea. The present study was performed to investigate the ex vivo effect of Zingiber officinale and Hizikia fusiforme on NO production in macrophage of mice. Seven to eight week old mices(Balb/c) were fed chew diet ad libitum and water extract of Zingiber officinale and Hizikia fusiforme was administrated orally at two different concentrations (50 and 500 mg/kg B.W.). every other day for two or four weeks NO(nitric oxide) production by activated macrophage was assessed by measuring nitrite, the stable NO metabolite, using Griess reaction assay. NO production were significantly enhanced in Zingiber officinale group at 500 mg/kg B.W. and in Hizikia fusiforme group at 50 mg/kg B.W. compared to the coresponding control groups. In conclusion, this study may suggest that Zingiber officinale and Hizikia fusiforme(sea weed fusiforme) extracts enhance the immune function by regulating NO production in macrophages of mice.

  • In this study, we performed an analysis of the accumulation of inorganic arsenic and growth rate with changes in phosphate concentration in Hizikia fusiforme. When exposed to inorganic arsenic for fourteen days, we found that the collection of inorganic arsenic hardly increased at high phosphate concentrations (2 mg L-1). However, when the phosphate concentration was low (0.02 mg L-1), accumulation of inorganic arsenic increased. Additionally, H. fusiforme decreased in a growth rate of 14.5% in low phosphate concentration (0.02 mg L-1) and fell in a growth rate of 30% when exposed to inorganic arsenic (10 ㎍ L-1). H. fusiforme cannot distinguish between phosphate and inorganic arsenic. Thus, when phosphate concentration was lower, the inorganic arsenic accumulation increased, and accumulated inorganic arsenic inhibited photosynthesis and cell division, reducing the growth rate. H. fusiforme is known to have higher inorganic arsenic accumulation than other seaweeds. Therefore, various studies are needed to secure the food safety of H. fusiforme which is an essential aquaculture species in Korea.

  • The purpose of this study was to investigate the changes of blood pressure and total cholesterol after eating Hizikia fusiforme for 8 weeks with 100g of rice per day. As a result, the systolic blood pressure of the group ingesting Hizikia fusiforme significantly decreased. Second, diastolic blood pressure decreased significantly in both groups, but there was no difference between groups. Third, the systolic - diastolic blood pressure difference showed a significant decrease in the group of ingestion of Hizikia fusiforme, while that of the group without intake of Hizikia fusiforme increased. Fourth, total cholesterol decreased significantly in the group consuming Hizikia fusiforme but increased in the group not consuming Hizikia fusiforme. The above results indicate that total intake of 100 g of dried Hizikia fusiforme per day was effective in decreasing total cholesterol and reducing systolic blood pressure.

  • This research focused on the effects of adding Hizikia fusiforme to Jeolpyun. We were able to demonstrate in this study that Jeolpyun after the addition of Hizikia fusiforme had the potential to become a functional food. Jeolpyun with 0, 2, 4, 6, and 8% of Hizikia fusiforme was analyzed by water content, color, sensory and textural characteristics immediately after production and one day later. The five different types of Jeolpyun did not show any significant differences in water content. However, all the Jeolpyun with Hizikia fusiforme showed slightly higher water retention ratio than the control after storage. As the result of Hunter's color values, lightness decreased significantly as the amount of Hizikia fusiforme increased. Redness increased in the Jeolpyun with Hizikia fusiforme compared with the control. Yellowness was highest in the Jeolpyun with 2% of Hizikia fusiforme and decreased with an increase in its content. In the textural analysis, hardness, chewiness, adhesiveness and gumminess of Jeolpyun with 2% and 4% of Hizikia fusiforme were similar to those of the control, whereas springiness of Jeolpyun with 2%, 4% and 6% of Hizikia fusiforme were similar to that of the control group. Cohesiveness significantly decreased as the amount of Hizikia fusiforme increased. When the Jeolpyun was preserved for one day, all five Jeolpyun showed significant increases in hardness, gumminess and chewiness. However, their adhesiveness significantly decreased. Cohesiveness decreased in all Jeolpyun except for the 8% Jeolpyun. In sensory evaluation, color and aroma became stronger as the content of Hijikia fuziforme increased, and 2% Jeolpyun showed similar hardness with the control. Jeolpyun with Hijikia fuziforme showed no difference in cohesiveness with the control, but the adhesiveness showed a little increase when compared to the control. The overall acceptability of 2% Jeolpyun showed slightly higher than control. After one day of storage, Jeolpyun with 2% of Hijikia fuziforme also showed the highest overall acceptability. And the overall acceptability showed the biggest decrease in the control group. Overall acceptability showed strong negative correlation with color, aroma and hardness, and showed strong positive correlation with cohesiveness and adhesiveness. After one day of storage, overall acceptability showed a decrease in correlation with color and smell and an increase in correlation with cohesiveness, compared to before storage. Results of multiple regression analysis showed that hardness had the biggest influence(-) on the overall acceptability of Jeolpyun, aroma and cohesiveness ranked second(-) and third(+) respectively. After one day of storage, cohesiveness had the biggest influence on the overall acceptability of Jeolpyun. Color and adhesiveness ranked second(-) and third(+) respectively. It can be seen that different factors influence overall acceptability of Jeolpyun after storage.

  • This study explored the effects of dietary calcium level and Hijikia fusiforme supplementation on bone indices and serum lipid levels using 36 female Sprague-Dawley rats as a model. Rats received low Ca diet for 3 weeks after ovariectomy. The rats were then divided into six dietary groups and fed low (0.1% Ca), normal (0.5% Ca) and high (1.5% Ca) Ca diets (CaL, CaN, CaH) and low, normal, high Ca diets with Hijikia fusiforme supplementation (CaLH, CaNH, CaHH) for 3 weeks. After each experimental periods, 24 hour urine and/or blood samples, left and right femurs were collected for analysis. Serum Ca concentration showed no significant difference by dietary Ca levels and Hijikia fusiforme supplementation. Alkaline phosphatase activity was significantly higher in normal and high Ca group compared to low Ca group. Serum total cholesterol, triglyceride and total lipid were not significantly different among groups. HDL-cholesterol showed no significant difference by Hijikia fusiforme supplementation. However, the normal and high Ca groups showed significantly higher HDL-cholesterol compared to the low Ca group. Urinary hydroxyproline and hydroxyproline/creatinine ratio were not significantly different among groups. The wet weight of the femur was significantly higher in low Ca group compared to normal or high Ca group. The dry weight, wet weight/body weight, length and breaking force of the femur were not significantly different among groups. Ash contents/wet weight of the femur was significantly increased as dietary Ca levels up and significantly higher in Hijikia fusiforme supplementation groups. The Ca content of the femur were significantly higher in the normal and high Ca groups than the low Ca group. However, there was no significant difference in Ca content by Hijikia fusiforme supplementation.

  • We previously reported that fermentation by Lactobacillus brevis LB-20 isolated from Kimchi resulted in improvement of the sensory quality of Hizikia fusiforme water extract. This study was conducted to evaluate the possible application of lactic acid bacteria fermentation to improve the functional qualities of H. fusiforme extract. L. brevis LB-20 was inoculated and cultivated in H. fusiforme extract. The antioxidant and anti-inflammatory activities of extract were then assayed both before and following fermentation for two days. Antioxidant activity was determined by assaying levels of radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl, superoxide, and alkyl radical. Lactic acid bacterial fermentation of H. fusiforme extract resulted in enhancement of antioxidant activity. The greatest enhancement of antioxidant activity was seen in the hydroxyl radical scavenging assay that incorporated 0.5 mg/mL of raw and fermented H. fusiforme extract. Fermented extract exhibited greater (21.95%) inhibition of nitric oxide synthesis than did raw extract (14.66%) at a concentration of 1 mg/mL. The fermented extract exerted its potent anti-inflammatory activity via attenuation of expression of inflammation-related cytokine proteins (TNF-${\alpha}$ and iNOS).

  • In this study, we investigated the effect of reaction factors on enzymatic hydrolysis of Hizikia fusiforme, which is brown algae in marine biomass resource, using commercial enzymes. The composition of H. fusiforme is 38.9% of reducing sugar, 4.8% of moisture, 17.8% of ash, and 38.5% of others. In the condition of 1-5% substrate, the increase of substrate concentration enhanced the increase of reducing sugar formation; however, the hydrolysis yield did not increase after 24 h. After reaction of 75 h, conversion yield of reducing sugar were obtained to 16.45%, 17.99%, and 14.55% at 1, 2.5, and 5% substrate, respectively. As a result of effect of enzyme amount, the formation of reducing sugar did not show considerable change at 1% substrate. However, in the condition of 2.5% substrate, the great change of reducing sugar formation was observed by the increase of enzyme amount. The conversion yields of reducing sugar were obtained to 18.77% and 22.83% at 1% and 2.5% substrate with 30% enzyme, respectively. As a result of heat treatment of biomass, the high yield was obtained in 2.5% substrate and the yields were increased to 0.06-7.2% by the heat treatment. This result will provide the basic information for production process of biofuels and chemicals from marine biomass H. fusiforme.

  • This study was conducted to improve the food functional and sensory food quality of Hizikia fusiforme by the fermentation of lactic acid bacteria. Seven strains of lactic acid bacteria isolated from traditional Korean fermented food were inoculated and cultivated in H. fusiforme water extract. Among them, Lactobacillus brevis LB-20, isolated from Kimchi, was selected for further study by considering the results of bacterial growth, DPPH radical scavenging activity, and sensory evaluation. No significant differences in proximate compositions (moisture, crude protein, crude fat, and crude ash) were observed by the fermentation of L. brevis LB-20. The most dramatical change was the conversion from glutamate to ${\gamma}$-aminobutyric acid (GABA) in H. fusiforme water extract fermented by L. brevis LB-20. The GABA content increased approximately 60-fold after 48 hr of fermentation. The bacterial fermentation also resulted in low-molecularization of the extract. The particle size of the fermented extract became approximately 4-fold smaller than that of the law extract. In addition, the analysis of volatile flavor compounds using GC/MS revealed that the bacterial fermentation dramatically removed off-flavors such as acetaldehyde, haxanal, diallyl disulphide and 1-penten-2-ol in the H. fusiforme extract.
