In this study the physiochemical characteristics and antioxidant activity of soybean curd were prepared with saltwort (Salicornia herbacea L.). The moisture and protein of the saltwort soybean curd showed no difference among the samples. Ash and lipid were found to be the highest in the soybean curd to which 20% saltwort was added. The contents of mineral(Fe, K, Mg, Zn) were highest in the soybean curd to which 20% saltwort was added, and Ca content was high in the soybean curd to which 16% and 20% saltwort was added. DPPH (1,1-dipheny1-2-picryl-hydrazyl) radical scavenging activity is a method of measuring the antioxidant power of food; this was high in the soybean curd to which 20% saltwort was added. Adding more saltwort led to higher scavenging activity. From the above results, it could be seen that the soybean curd, which is made by adding saltwort, contributed to enhancing the functionality of antioxidant activation and product quality.

This study performed physicochemical characteristics and sensory tests on brown sauce with different Salicornia herbacea L. (saltwort) content to find the best brown sauce recipe with saltwort. Moisture content increased with greater saltwort extract content. There was significant (p<0.001) pH difference with saltwort content. There was also significant (p<0.001) sweetness difference in the samples and sweetness increased with greater saltwort content. Viscosity measured at $20^{\circ}C$ and $60^{\circ}C$ was significantly (p<0.001) lower with greater saltwort content. The brightness of brown sauce containing saltwort extracts significantly (p<0.001) increased with greater saltwort content and its redness and yellowness usually decreased. SPS4 with the greatest saltwort content showed the highest value of 4.25% and DPPH radical removal increased significantly (p<0.001) with greater saltwort content. In the sensory test, the color value was lowest at 4.82 with BSL1 and the flavor value was lowest at 5.00 with BSL0, the control group. The taste and the flavor values were highest with BSL2 with 2% saltwort content. Overall acceptance was highest with BSL3, the brown sauce with 3% saltwort content, at 6.09. As a result, it was concluded that the brown sauce with 3% saltwort content was most suitable. Therefore, this study concluded that saltwort with various functions could be used for food and may be used to replace salt and have other functions in brown sauce, a popular sauce consumed in Korea.

Soybean powder is a readily-available food ingredient. Furthermore, saltwort powder is an herb with various physiological effects. Therefore, in this study we examined the physiochemical characteristics of soybean dasik prepared with 0, 4, 8, and 12% saltwort powder. We measured Hunter's color values, mechanical characteristics, and sensory qualities. The result of each analysis is as follows. There were not significant differences between the moisture content of the control group and the groups with saltwort powder. The ash content increased while the fat and protein content decreased as the ratio of saltwort powder increased (p<0.001). In the analysis of color differences, the L, a, and b values decreased as the ratio of saltwort powder increased (p<0.001). The hardness (p<0.001) of the groups increased as the ratio of saltwort powder increased, but adhesiveness decreased. Sensory evaluation data showed that softness, hardness, and chewiness decreased while color increased as the ratio of saltwort powder increased. Finally, aroma, sweet taste, nutty taste, and overall acceptability was shown to be best for the 4% addition group.

Saltwort (Salicornia herbacea L.), a kind of halophytes in Japan, is under investigation as a feed source for livestock as well as potential oilseed crop in salt marshes and salt fields. The present experiment was undertaken to analyze the nutritive value of saltwort as feed for ruminants. To determine the apparent digestibility and nutritive value of saltwort, five Japanese native goats were fed the diets consisting of alfalfa hay cubes with 15 or 20% (n=3 and n=2, respectively) inclusion levels of saltwort in the total diet on a DM basis. All the animals were randomly offered alfalfa hay cubes as a base diet or a mixed diet of alfalfa hay cubes and saltwort at maintenance level, thereafter, alternative feed (a base or mixed diet) was offered to the experimental animals (the incomplete crossover design). Analysis of the chemical composition of saltwort showed that the plant contained high levels of total ash (40.2% DM), sodium (12.7% DM) and chlorine (19.7% DM), and relatively high levels of CP (11.7% DM) and NDF (40.4% DM). Contents of TDN and digestible CP (DCP), DE and ME of saltwort were 33.5% DM, 8.4% DM, 7.4MJ/DM kg and 5.0MJ/DM kg, respectively. These results indicate that saltwort is rich in DCP and minerals (mainly sodium chloride), but poor in energy, suggesting that saltwort could be used as a mineral or CP supplement for ruminants raised around salinized areas in which high quality feed may not be available.

This study was conducted to investigate the effects of saltwort on the quality characteristics of tofu. In addition, we examined the potential for commercialization of tofu containing saltwort. For this study, saltwort was added to tofu at 0%, 4%, 8%, 12%, 16% and 20% and quality and sensory tests were administered. Analyzing the mineral contents of saltwort juice, K was present in the greatest amount, followed by Mg, P, Ca, and F (in decreasing order). There were significant differences in yield rates and turbidity between the groups. Acidity was highest in the control group, and acidity and volume of tofu tended to decrease with an increase in saltwort powder. L value and a value decreased as the content of slaltwort powder increased, but b value increased with increasing saltwort powder concentration. Hardness, chewiness, and gumminess were rated higher in the control and the 4% supplement groups than the others groups. In the sensory evaluation, cross section and soybean flavor were the highest in the 4% saltwort supplement group, and the presence of an "off-flavor" increased with the content of saltwort powder. The saltiness score was highest in the 20% supplement group. The 4% and 8% supplement groups were favored in the "feel after swallowing" assessment. Softness was the lowest in the 20% supplement group, and the 4% supplement group had the highest overall acceptability. As demonstrated by these results, the addition of saltwort positively affected the overall sensory evaluation of tofu and supplementation with saltwort at 4% and 8% might be considered the most appropriate choices. In conclusion, saltwort tofu expected to increase the functionality of new products, particularly with respect to product variety and health improvement.

To obtain basic data for the utilization of saltwort (Salicornia herbacea L.) as a functional ingredient in steamed foam cake, the optimum component ratios for major raw ingredients (saltwort, salt, and wheat flour) as independent variables that affect the product quality were scientifically determined using RSM (response surface methodology) technique. A three-factor and five-level rotational central composite design was used for treatment arrangement. The complete design consisted of 16 experimental points. The three independent variables selected for the RSM experiment were amounts of saltwort (X$_1$, 5${\sim}$25 g), salt (X$_2$, 0${\sim}$10 g), and wheat flour (X$_3$, 470${\sim}$530 g). The optimum responses in specific gravity of the batter and volume, color, texture, and sensory evaluation result of the cake were obtained. The specific gravity and viscosity of the batter at p<0.01 was verified from the regression curve. The characteristic of the batter was influenced by all independent variables, but was extremely dependent on the amount of saltwort ordinary points of the surface responses from the batter formed the minimum points for specific gravities of the batter while viscosities of the batter appeared with the saddle points. Analysis of the response indicated that the amount of saltwort was the most influential factor over the physical properties of the cake, among the dependent variables. Ordinary points of the surface responses from the cake formed the maximum points for loaf volume, hardness gumminess, and chewiness, while Hunter colorimetric parameters appeared with the saddle points. The result indicated that level of the saltwort deviating more or less from the optimal amount decreased the volume and increased the specific gravity with less tender product. Ordinary points of the surface responses of the sensory evaluation scores from the cake formed the maximum points for appearance, flavor, softness, and overall acceptability, while color values appeared with the saddle points. The result also indicated that the level of the saltwort deviating more or less from the optimal amount reduced the preference for the product. Integration of the optimum responses common to all dependent variables that overlapped all the contour maps finally indicated that the combination of 8.3${\sim}$13.8 g saltwort, 2.5${\sim}$6.6 g salt, and 486.5${\sim}$511.5 g wheat flour under the selected preparation recipe optimized the physical and sensory properties in the teamed foam cakes. Practical preparation of the product with median amounts of the ingredients, i.e., 11.0 g saltwort, 4.6 g salt, and 499.0 g wheat flour resulted in similar qualities to the predicted responses. In conclusion, these study results indicated that preparation of steamed foam cake with added saltwort ingredient could potentially produce a more nutritious product with less salt. Further research is required to acquire the optimum levels for sub-ingredients to improve the product quality.
