We studied the effects of the powders of Spirulina platensis (SPP) on anaphylactic reactions. SPP inhibited systemic anaphylaxis induced by compound 48/80 in rats. SPP also inhibited local anaphylaxis activated by anti-dinitrophenyl(DNP) IgE. Moreover, SPP dose-dependently inhibited histamine release in rat peritoneal mast cells activated by compound 48/80 or anti DNP-IgE. These results suggest that SPP may contain compounds with actions that inhibit mast cell degranulation in the rat.

A simple and sensitive analysis method based on reverse phase (RP) HPLC with UV detector was developed for simultaneous determination of chlorophyll a and b, pheophorbide a and $\beta-Carotene$ in Chlorella and Spirulina products. For added concentration $(50\;\mug/ml)$ of chlorophyll a and b, pheophorbide a and $\beta-Carotene$, recoveries of those were 70.3, 71.6, 60.1 and $90.5\%$, respectively, with relative standard deviations of 2.8,6.0, 10.6 and $10.4\%$. Limit of detection and quantification had ranges of $0.1\sim1.0\;\mug/ml$ and $0.2\sim2.0\;\mug/ml$, respectively. Calibration curve was linear with correlation coefficient of 0.995 for chlorophyll a and b, pheophorbide a and $\beta-Carotene$. Results of simultaneous determination in Chlorella and Spirulina products were showed ranges of $121.g\sim543.0\;\mug/ml$ for chlorophyll a,$0.6\sim160.0\;\mug/ml$ for chlorophyll b, $19.2\sim60.3\;\mug/ml$ for pheophorbide a and $383.6\sim1713.7\;\mug/ml$ for $\beta-Carotene$, respectively. Chlorophyll b contents in Chlorella products were detected above 30 times level to those in Spirulina products. $\beta-Carotene$ contents in Spirulina products were detected 2.7 times level to those in Chlorella products.

Storage quality characteristics of low fat salad dressing with spirulina($0.28\%$) was evaluated. After 2 wks of storage, viscosity decreased according to the prolonged storage time. After 8 wks storage, emulsion stability decreased to $30\%$, which was $25\%$ of freshly made dressing. The fat globule size distribution was not different from that of control until one month of storage, but after 75 days of storage, the fat globule size distribution pattern changed into the increase of larger size($15{\sim}2.0\;{\mu}m$: $11.4\%$ for control, $30.1-32.3\%$ for 75 days of storage). Hunter color of L value decreased, whereas a and b value increased according to the prolonged storage time. TBARS value at 8 wks of storage was increased upto $10\%$ for storage at $5^{\circ}C$ and $15\%$ for storage at $10^{\circ}C$. Antioxidant activity of salad dressing decreased according to the storage temperature and time: $IC_{50}$ values of DPPH radical scavenging activity of 8 wk storage was 157.4 mg/mL at $5^{\circ}C$ and 194.6 mg/mL at $10^{\circ}C$. Total microbial number of salad dressing was increase to 7.9 log(CFU/mL), but E. coli was not detected Based on present condition, low temperature storage was favorable for better quality of spirulina salad dressing.

This intervention study was performed to assess the effect of spirulina on lipid metabolism, antioxidant capacity, and immune function in elderly Koreans. The subjects were 6 male and 6 female people between the ages of 60 and 75, who were given spirulina supplements of 7.5 g/day for 24 weeks. Dietary intake, anthropometric measurements and biochemical assessment for plasma lipid levels, antioxidant status and immune function were measured before and throughout the intervention period. Before entering the study, the subjects were in relatively good health. Their nutrient intake was satisfactory, and anthropometric indices and plasma nutrient levels were within the normal range. Spirulina supplementation for 24 weeks did not affect dietary intake and anthropometric parameters. However, considerable changes were observed in blood lipid profiles, antioxidant capacity, and immune indices. The plasma concentrations of triglycerides, total- and LDL-cholesterol decreased from 4 weeks of the supplementation period. The antioxidant capacity improved, as shown in increasing TAS and decreasing TBARS after supplementation. Improved immune function was also observed as the PBL lymphocyte proliferation rate and plasma C3 levels increased. The above effects of spirulina supplementation did not differ between mild hypercholesterolemic (cholesterol $\geq$ 200mg/d1) and normochole-sterolemic (cholesterol < 200 mg/dl) subjects. This study provided evidence that spirulina could be used as dietary supplementation in nutritionally vulnerable groups to improve nutritional and health status and to prevent chronic disease such as hyperlipidemia or oxidation-prone diseases. further studies in this area with various population groups are warranted.

The purpose of this study was to investigate the quality characteristics of fish paste added with different amounts (0%, 0.5%, 1%, 1.5%, and 2%) of spirulina powder. Specifically, moisture content, pH value, color value, texture value, total polyphenol content, DPPH radical scavenging activity, and sensory evaluation were measured in the samples. The moisture content of the fish paste added (0.5%, 1%, 1.5%, and 2%) ranged from 68.60% to 69.03%, and the increased amounts of spirulina powder in the fish paste tended to decrease the pH value. For the Hunter color values, the L, a values of surface and inside of the fish paste decreased with increased amounts of spirulina powder. The b values of the fish paste increased with increased amounts of spirulina powder. In the texture meter test, the hardness, gumminess, and adhesiveness decreased with the increased amounts of spirulina powder, and chewiness of group adding spirulina powder was measured lower than control. Springiness of the fish paste did not appear statistically significantly different among the samples according to the increased amounts of spirulina powder. Total polyphenol content of fish paste added with spirulina powder increased with increased amounts of spirulina powder, and DPPH radical scavenging was heightened according to increased amounts of spirulina powder. In sensory evaluation, the addition of 1% spirulina powder had the best score in odor, texture, taste, and overall preference. These results suggest that spirulina powder can be applied to fish paste to increase quality, preference, and functionality.

In this study, the quality characteristics of tofu prepared with added spirulina(0, 0.25, 0.5, 0.75, and 1%). As the concentration of spirulina increased, tofu yield decreased and the pH and turbidity increased. The Hunter L(lightness) and a(redness) values of tofu decreased as the amount of spirulina increased. Phycocyanin(C-phycocyanin, allophycocyanin and phycoerythrin) contents increased according to the spirulina amount. Moreover the antioxidant activity of tofu increased as the concentration of spirulina increased($IC_{50}$ values for control was 150.7 mg/g; 1% spirulina, 82.5 mg/g). Textural properties(TPA) for hardness, gumminess, and chewiness were higher in spirulina with added tofu, compared to those of control. Regarding the overall acceptability of sensory properties, spirulina with 0.5% added tofu had the highest scores among all treatments. From these results, it was suggested that the optimal amount of added spirulina was 0.5% for the preparation of high quality tofu.

The principal objective of this study was to determine the optimal mixing ratios of three different quantities of spirulina, salt and water for the preparation of Korean rice cake (Dukbokiduk) via response surface methodology on the basis of color, texture, and sensory test. The spirulina levels were tested in a range of $1{\sim}3%$, the water levels in a range of $15{\sim}25%$, and salt levels were tested a range of $0.5{\sim}1%$ by weight of rice powder. Taste was influenced most profoundly by the amount of added spirulina. Optimal taste was achieved with 1% of spirulina, 0.75% of salt and 20% water. Thus, the optimal mixing ratios of spirulina, salt, and water for Dukbokiduk were 1.0%, 0.57%, and 19.46%, respectively.

Riceyeotgangjung (RYG) with added spirulina was prepared with citron juice for masking of odor. Oil temperature for puffing was found to be $220^{\circ}C$ for frying dry rice based upon the results of expansion rate and color. RYGs with added spirulina (1, 2, and 3%) were prepared under the above conditions, and their physicochemical and sensory properties were examined under storage at $60^{\circ}C$ for 15 days. Moisture content of RYG decreased proportionally with the spirulina content and storage time. The hardness levels of the freshly made RYGs with spirulina were higher than that of control. During storage, the hardness of the control gradually increased, but those of the RYGs with spirulina gradually decreased, although no significant differences existed between the spirulina containing RYGs. Lightness and redness values in the Hunter color system decreased according to the spirulina content and storage time. Yellowness value also increased with the spirulina content and storage time. Phycocyanin and total phenolic content increased with spirulina content, but decreased with the storage period. Sensory evaluation results showed that RYG with 2% added spirulina received the highest scores for color, taste, overall acceptability, and intention of purchase. As a result, the optimal addition amount of spirulina to RYG is recommended to be 2%.
