The principal objective of this study was to determine the optimal conditions for making muffins with sea-tangle powder, which is known to be a healthy food supplement. The characteristics of the sea-tangle muffins were analyzed in a quality evaluation. Sea-tangle powder was added to the muffins at concentrations of 0%, 5%, 10%, 15%, 20% prior to baking. The height of the muffins to which the sea-tangle powder had been added, after storage at $20^{\circ}C$, was shown to decrease with increases in the concentration of sea-tangle powder. The weight of the muffins increased with increasing storage time, but these differences were not profound. The moisture content of the muffins decreased with increased storage time. The change in pH in accordance with storage time differed only slightly. In terms of the color of the sea-tangle powder-supplemented muffins, after storage at $20^{\circ}C$, the “L” and “b” values decreased with increasing amounts of added sea-tangle powder. The “a” value increased with increasing amounts of added sea-tangle powder. With regard to the textural properties of the sea-tangle powder-supplemented muffins, after storage at $20^{\circ}C$, the hardness and chewiness increased with greater quantities of added sea-tangle powder. Springness, cohesiveness, and adhesiveness differed only slightly as more sea-tangle powder was added. With regard to the sensory characteristics of the muffins, the overall quality of the muffin to which 10% sea-tangle powder was added was evaluated as the best. The color, flavor, and softness were also assessed as the highest. The sweetness of the muffins was assessed as weak.

Breakfast sausages containing 1, 2, 3, and 4% sea tangle powder (Lamina japonica) were prepared. No differences were found in moisture, protein, and fat contents among the control and treatments. However, the ash content increased with increasing amounts of sea tangle powder (p<0.05). The pH levels in the treated samples were lower than the control in both the meat batters and the breakfast sausages (p<0.05). The $L^*$ and $a^*$ values of the meat batters and breakfast sausages were decreased by the addition of the sea tangle powder, and the control had the highest $b^*$ value (p<0.05). The added sea tangle powder improved cooking loss and improved emulsion stability. The T4 sample (containing 4% sea tangle powder) was shown to have the lowest cooking loss and water loss (p<0.05). The hardness, gumminess, and chewiness of the treatments increased compared to the control due to the presence of dietary fibers in the sea tangle. In the sensory evaluations, the 1% sea tangle powder treatment received a lower color score, but received significantly higher scores for flavor, tenderness, and juiciness (p<0.05). Collectively, the breakfast sausage containing 1% sea tangle powder was determined to have the highest overall acceptability. Altogether, the best results, in terms of physicochemical and sensory properties, were obtained for the breakfast sausage containing 1% sea tangle powder.

Dieary effects of sea tangle on immune functions were investigated in diabetic mice. Four groups of ICR mice weighing 33.36$\pm$1.01 g were fed either an AIN-76 diet only (control), or with additional sea tangle powder, sea tangle water extract, and alginate at the level of 13.6%, 4%, and 1%, respectively by weight. Cellulose was omitted in sea tangle powder and alginate diets. After 10 days of feeding respective experimental diets, all mice were made diabetic by five consecutive intramuscular injections of streptozotocin (40mg/kg body weight per day) and fed the diets for four more weeks. Plasma IgG concentrations but not those of IgM were significantly higher in mice fed sea tangle powder, extract or alginate than those on the control diet. Plasma TNF$\alpha$ levels were, however, lower in those fed sea tangle power or water extract than control and alginate fed groups. TNF$\alpha$ releases from macro phages isolated from four groups and cultured with 5 $\mu\textrm{g}$/mL LPS for 24 hors showed a similar tendency to the results of plasma concentrations in the respective groups, but IL-1$\beta$ releases were not different among four groups. Lymphocyte proliferation in response to LPS (10$\mu\textrm{g}$/mL) measured using splenocytes cultured for 3 days was highest in the alginate fed group (594$\pm$38%) and those of sea tangle powder (536$\pm$47%) and extract (547$\pm$34%) fed groups tended to be higher than the control (523$\pm$30%). It is concluded that sea tangle contains immunomodulatory components besides alginate that could enhance humoral immunity of itself. The immunomodulatory effects of sea tangle constituents is regarded as beneficial for diabetic subjects.

Purpose: This study investigated the quality characteristics of Jeungpyun prepared with brown rice and sea tangle powder. Methods: The pH, volume, and spreadability of the dough and moisture content, color, texture and sensory evaluation of the Jeungpyun were performed. Results: The results showed that the pH of the dough decreased in all sample groups with the lapse of fermentation time, and ultimately revealed a pH ranging from 4.55-4.65. The spreadability of the dough significantly decreased as the substitute amount of the brown rice flour increased; the sample group with 1% sea tangle powder showed a significantly larger spreadability than the sample group with 2% sea tangle powder (p<0.05). The moisture content in the Jeungpyun showed a significantly lower result as the substitute amount of brown rice flour increased (p<0.05). Lightness (L) was reduced as the substitute amount of brown rice flour increased, and redness (a) and yellowness (b) also appeared to increase. As a result of measuring the texture, the 50% sample group with a high substitute rate of brown rice flour was observed to have high characteristics of hardness, gumminess and chewiness, and was low in cohesiveness. The result of the acceptance test showed that the sample group that substituted 25% brown rice flour and added 1% sea tangle powder was evaluated to have a significantly higher acceptance than the sample group that added 2% sea tangle powder in terms of color, texture and overall acceptance. Conclusion: The result of the acceptance test showed that the sample group that substituted 25% of brown rice flour and added 1% of sea tangle powder showed higher tendency in all acceptance attributes than the sample group that did not substitute the brown rice flour to show the possibility of developing the Jeungpyun with brown rice.

In order to study low salinity Oiji (cucumber pickled in salt) with a reduced content of sodium, which was accomplished by replacing the salt in this saliferous food, we produced Oiji using sea tangle and, then performed physicochemical and sensory evaluations. It was found that the moisture content of Oiji was decreased with increasing the amount of added sea tangle. The pH and acidity were significantly different between the samples made with sea tangle, and the pH and acidity showed no consistent tendency according to the amount of sea tangle powder added. The salinity of Oiji was the highest in the control Oiji (2.92%), and the higher the amount of sea tangle added, the lower was the salinity in the Oiji with the salt replaced by sea tangle (2.78 to 2.89%). The sodium content of Oiji was also the highest in the control Oiji (591.65 mg/100 g) and significantly decreased with the increasing addition of sea tangle (560.43~366.71 mg/100 g). The color value of Oiji showed a significant difference between the samples, with no consistent tendency according to the amount of added sea tangle powder. The hardness of Oiji was significantly greater in the Oiji with the salt replaced by 40% of sea tangle, with greater hardness noted as the amount of added sea tangle powder increased (217.70 g). As a result of the acceptance test of Oiji, there were significant differences between the samples in overall acceptance, appearance, and taste, showing that the Oiji with salt replaced by 30% of sea tangle was significantly highest in overall acceptance and taste. The attribute difference test showed a significant difference only for the brown color, while no significant differences were found between the samples for off-flavor, bitter taste, fermented taste, salty taste, sour taste, hardness and crispness. The above results demonstrated that when sea tangle was substituted for 30 to 40% of the salt content, the Oiji with a low content of sodium and low salinity can be produced with a high level of taste and overall preference. Therefore, this study firmly demonstrated that 30 to 40% of the salt can be replaced by sea tangle as a substitute in order to produce Oiji that has low salinity, a low sodium content.

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).

Obtaining powder form of seaweed is essential for the use of seaweed as a food additive. The deterioration of seaweed caused by high temperatures during homogenization and powder processing is a serious problem and limits the use of seaweed as a food or pharmaceutical ingredient. Furthermore, many powder particles are not fluidized very well because of the interaction between particles. In order to solve this problem, sea tangle was hydrolyzed to a level of single cell detritus (SCD) by Vibrio sp., isolated from Batillus cornutus. with strong hydrolytic activity. The crude protein and amino acid contents of sea tangle SCD were higher than those of the powder, whereas the reverse was true for ash content. Sea tangle powder contained more mineral than its SCD, whereas total amino acid content was 5 times more in SCD than in power. The anticancer activities of sea tangle SCD and powder were 31.20 and 29.07%, respectively, with no significant difference (p<0.05), but about 15% higher than that of the control. The ACE inhibitory activity of the sea tangle powder, 39.31%, was higher than the 26.07% of the SCD. The antithrombin activity of the sea tangle powder, 55.3 seconds, was higher than the 34.5 seconds of the SCD. Moreover, there was no antioxidative and ischemic activities in both tile sea tangle powder and SCD.

This study was carried out to investigate antimutagenic and cytotoxic effects of Korean traditional Mackjang added with sea tangle powder. The content percentage of most of minerals among general composition increased by adding sea tangle powder. By the Ames test, the antimutagenic effect of ethanol extract of Korean traditional Mackjang added with 5% sea tangle powder was strongest exceeding the control, 10%, and 15% sea tangle additions. The ethanol extract (400$\mu$g/plate) of Mackjang added with 5% sea tang1e powder in the S. typhimurium TA 100 strain showed inhibition rate of 95.0% against the mutagenesis induced by MNNG. The inhibition rate of ethanol extract (400$\mu$g/plate) of Mackjang added with 5% sea tang1e powder in the S. typhimurium TA98 and TA100 strains was 81.4% and 88.8%, respectively, against the mutagenesis induced by 4NQO. Under the same conditions, the suppression against B($\alpha$)P and Trp-P-1 in the TA98 and TA100 strains were 85.3% and 91.0%, and 96.5% and 96.5%, respectively. For the anticancer effects, an investigation was done on the cytotoxicity of Mackjang added with 5% sea tangle powder on the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2), and human gastric carcinoma (KATOIII). The cytotoxicities were inhibited with increasing the extract concentration. The treatment of 1.0 mg/mL Mackjang added with 5% sea tang1e powder showed relatively strong cytotoxicity of 61.2%, 61.8% and 66.8% against A549, KATOIII, and HepG2, respectively.

The purpose of this study was to investigate the effect of dietary supplementation of sea tangle (Laminaria japonica) on the blood glucose and lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into 3 groups fed control, sea tangle powder (15%, w/w), or sea tangle water extract (4%, w/w) diet. Diabetes was induced by a single injection of STZ (60 mg/kg, i.p.) in citrate buffer. The animals were fed each of the experimental diet for 13 weeks. Serum insulin was increased by dietary supplementation of sea tangle in diabetic rats. Dietary sea tangle reduced blood glucose level of diabetic rats compared to the diabetic rats fed control diet. Dietary sea tangle also reduced the serum total cholesterol, low density lipoprotein (LDL)-cholesterol, and triglyceride in the diabetic rats. While hepatic lipids were reduced, fecal excretion of lipids was increased by supplementation with dietary sea tangle in the diabetic rats. These results indicate that dietary sea tangle decreased blood glucose and improved lipid metabolism in STZ-induced diabetic rats and this effect might be exerted by increases in serum insulin and fecal excretion of lipids.

This study showed the optimum conditions for producing rice extrudate added with the sea tangle powder, and presented the effects of moisture content, barrel temperature and the amount of sea tangle powder. From the results, the more the amount of sea tangle powder was added, the less the water absorption ratio was showed, while the more the texture became smooth, the more the expansion ratio increased. From the sensory evaluation, the best preference was obtained when the moisture content was $18\%$, and the barrel temperature was at $100^{\circ}C$. Between control and $10\%$ sea tangle, there was no significant difference in all observed parameters. But if more than $20\%$ sea tangle was added, low sensory evaluation scores were obtained due to the peculiar smell from sea tangle. From these results, addition of sea tangle below $10\%$(w/w) did not affect the quality of products.
