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.

This study was conducted to investigate the quality characteristics of bread prepared with spirulina powder (0, 0.4, 0.8, and 1.2%). The volume and specific volume of bread decreased with increasing spirulina powder content. The pH of the bread with 1.2% spirulina powder was the highest. Content of phycocyanin increased with addition of spirulina powder. For color values, increasing spirulina powder content resulted in decreased lightness, redness, and yellowness in the crust. Amylogram showed that spirulina addition increased initial gelatinization temperature, decreased breakdown, and lowered the setback and consistency, which prevented retrogradation. Moreover, the hardness of spirulina bread decreased as spirulina addition increased. Further, springiness, cohesiveness, gumminess, chewiness. and resilience of bread with 0.8% spirulina powder were the lowest. Sensory results showed that the scores of overall preference and buying intention in the bread with 0.8% spirulina were the highest among the control and other groups.

This experiment was carried out to investigate the effects of spirulina powder on the growth properties of lactic acid bacteria in reconstituted skim milk. The spirulina powder supplemented to S. thermophilus and L acidophilus slightly stimulated lactic acid production. In addition, the growth and acid production of L. bulgaricus were enhanced by the addition of spirulina powder. When the spirulina powder was added to reconstituted skim milk at the level of 1%, the mixed cultures of S. thermophilus and L. bulgaricus showed higher numbers of viable cells and higher acid production than the other cultures. The effects of the addition amounts of spirulina powder (1%, 2% and 3%) to the reconstituted skim milk on the growth properties of the mixed cultures of S. thermophilus and L. bulgaricus were evaluated. The pH of the skim milk with added spirulina powder was lower than that of the control, but the amount of spirulina did not have a significant affect. The titratable acidity increased with the incubation time until 12 hr. The number of viable cells in the skim milk with added spirulina increased according to the amount of spirulina. Thus, the spirulina was effective for the increasing lactic acid bacteria in yoghurt.

This study investigated the effect of supplement of the pigment source in diets on body color for round tailed paradise fish Macropodus chinensis and the pale chub Zacco platypus. Fish (the round tailed paradise fish: 1.6 g/ fish, pale chub: 2.4 g/fish) were fed diets containing various pigment sources (Porphyra powder, Spirulina powder. yeast astaxanthin and paprika extract) twice a day for 6 weeks. Survival of all treatments was above 80%. Weight gain and total carotenoid contents of round tailed paradise fish fed the diet containing Porphyra powder was higher than that of fish fed the other diets. The apparent redness of skin and fin in round tailed paradise fish fed the diets containing paprika extract and yeast astaxanthin was better than that of fish fed the diets containing Porphyra powder, Spirulina powder and the control diet. Weight gain and total carotenoid contents of pale chub fed the diet containing paprika extract were higher than that of fish fed the containing Porphyra powder, yeast astaxanthin, Spirulina powder and the control diet. The apparent redness of skin and fin in pale chub fed the diets containing parika extract and yeast astaxanthin was better than that of fish fed the diets containing Porphyra powder, Spirulina and the control diet. The results of this study suggest that dietary supplementation with paprika extract and yeast astaxanthin can improve redness of skin and fin of round tailed paradise fish and pale chub.

The objective of this study was to develop high quality Riceyeotgangjung (RYG) with high antioxidant activity and a longer shelf-life. Spirulina (1, 2, and 3%) with added RYG was prepared, and antioxidant activities were examined under storage at $60^{\circ}C$ for 15 days. The total phenol content remaining in the spirulina with added RYG at 15 days of storage was much higher than that of fresh RYG without spirulina. The IC50 values for DPPH and hydroxyl radical scavenging activities decreased with increasing amounts of spirulina, whereas these values increased with storage time. TBA and peroxide values decreased with increasing amounts of spirulina. From these results, adding spirulina to RYG delayed lipid rancidity and prolonged shelf-life. Adding spirulina powder to RYG, which is a healthy functional food material, improved antioxidant activity and delayed deterioration during storage.

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%.

A 20-week growth trial was conducted in flow-through aquarium system to investigate the effects of supplemental macroalgae and spirulina in the diets on growth and body cmposition in juvenile abalone (Haliotis discus hannai). Four replicate groups of the abalone averaging 65mg were fed one of ten isonitrogenous (34%) and isolipidic (7.5%) diets containing 8.1% Ulva, 7.5% Undaria, 11% Laminara, 11% Sargassum, spirulina (5, 10 and 15%), or dried Undaria powder (10 and 20%). In addition, these formulated diets were compared with natural food(dried Undaria). Survival rate of abalone were not significantly affected by the different dietary macoralgae sources, spirulina or dried Undaria powder levels (P>0.05). Weight gain and soft body weight of abalone fed the diet containing Sargassum was significantly higher (P<0.05) than those of abalone fed the diets containing Laminaria, 20% dried Undaria powder and natural food. Survival rate, weight gain, soft body weight and shell length of abalone fed natural food were lowest (P<0.05) among all diet. Moisture, protein and lipid contents of soft body were not influenced by experimental diets except natural food. Lipid content of abalones fed natural food was significantly lower than those of abalone fed other diets (P<0.05). These data indicate that abalone can more efficiently utilize Sargassum than Ulva, Undaria, Laminaria or spirulina.

This study was conducted to investigate effects of dietary pigment sources on shell color of juvenile abalone, Haliotis discus hannai. Three replicate groups of the abalone, average weight 173 mg, were fed the diets containing various pigment sources such as Porphyra powder, Spirulina, yeast astaxanthin and paprika extract for 16 weeks. Survival and weight gain were not affected by dietary pigment sources (P>0.05). Shell color of abalone fed diets containing Porphyra powder and Spirulina was approached to yellow-red and orange which are similar to shell color of wild abalone. However, shell color of abalone fed the diets containing yeast astaxanthin and paprika extract were similar to that of control diet showing bright green. Porphyra powder and Spirulina contain not only fat-soluble pigment such as chlorophyll and carotenoids but also water-soluble pigment such as phycoerythrin and phycocyanin. These results would be useful information to change shell color of abalone in aquaculture.
