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.

To encourage rice consumption, this study investigated the quality characteristics of fish cakes containing four different amounts (0%: control, 50%, 75%, 100%) of rice flour. The moisture and pH of fish cake dough and fat contents, color values, folding score, texture profiles and consumer acceptability of fried fish cakes containing rice flour were measured. There were no significant difference on moisture and pH of fish cake dough containing rice flour. There was significant decrease in terms of fat contents, folding score of the fish cakes with increasing rice flour(p<.05). While a and b values were increased, L value decreased significantly, as the ratio of rice flour increased(p<.05). Hardness, cohesiveness, gumminess and chewiness of fish cakes with rice flour decreased significantly (p<.05), but no significant difference in springiness. There were no significant differences in overall acceptance, appearance, flavor, color and taste between the control group and treatment groups(p<.05). Texture was decreased significantly as the rice flour increased(p<.05). This study suggests that adding fifty percent rice flour to fish cakes could be a good way to increasing rice flour without decreasing texture acceptability.

This study was conducted to investigate the effect of gelatin concentration and storage on color and texture of puffer fish stock jelly. Puffer fish stock jelly was prepared by adding various amounts (2.5~10 percent) of gelatin to puffer fish stock. Color changes of puffer fish sstock jelly were also investigated during storage at $4^{\circ}C$ and $25^{\circ}C$ with varying amount of gelatin (2.5~10.0 percent). Regardless of storage temperature, the L values of puffer fish stock jelly were slightly increased, while a values of the stock jelly were negatively decreased during storage. However, L and negative b values were decreased with increasing gelatin concentration, whereas a values were increased negatively with increasing gelatin concentration. The texture profiles of puffer fish stock jelly such as hardness, springiness, cohesiveness adhesiveness, chewiness and brittleness were determined during storage at $25^{\circ}C$ and $4^{\circ}C$ at various intervals. The hardness, chewiness and brittleness were increased during storage at $25^{\circ}C$ for four days, while those of springiness and cohesiveness were decreased during storage. However, the values of all textural parameters were increased with increasing gelatin concentration in puffer fish stock jelly. Patterns of textural parameters of puffer fish stock jelly stored at $4^{\circ}C$ were practically identical to those stored at $25^{\circ}C$.

The aim of this research was to determine the relationship between quality of puffer fish and soak time in maturing water. This research used the cutting cranial nerve method, which is called the MSK method. The data was analyzed using the SPSS program. Based on salinity analysis result, both moisture content and pH were measured after 20 min of soaking. As the salinity of the maturing water increased, the moisture content initially decreased then increased once the salinity was greater than 3%. However, the concentration of the maturing water did not influence the pH level. The texture properties were measured to assess the effect of soak time in the maturing water. Hardness of the sample was highest (3.99) at 20 min, and cohesiveness also showed a maximum value (0.26) at 20 min. Gumminess and chewiness were highest 1.04 and 4.09, respectively, when the fish was matured for 20 min. Sensory properties were evaluated, and springiness, umami flavor, texture, and overall preference were highest at 20 min of soak time. The results showed that maturing the puffer fish for 20 min provided the best quality of texture and sensory characteristics for the fish.

This study was conducted to promote the utilization of fish paste containing four different amounts (0%: control, 2, 4, and 6%) of cheonggukjang powder. For Hunter color values, L values of samples decreased as concentration of cheonggukjang powder increased, and a and b values increased. Folding tests for all samples showed good flexibility. In the texture meter test, hardness, cohesiveness, and springiness increased according to increasing concentrations of cheonggukjang powder. However, gumminess and brittleness of fish paste were reduced upon addition of cheonggukjang powder. In the sensory evaluation, fish paste prepared with 2% cheonggukjang powder was more preferred over other fish pastes. This study suggests that addition of 2% cheonggukjang powder to fish paste could be a good way to increase cheonggukjang powder without decreasing texture acceptability.

본 연구에서 시판 연제품류의 전분함량을 분석한 결과 현재 시판되고 있는 대부분의 연제품류의 전분함량은 튀김어묵, 맛살류 그리고 진어묵 순으로 적었으며 그 함량은 각각 $16.5\sim20.6\%,\;12.4\sim17.3\%,\;8.1\sim8.7\%$ 범위였다. 특히 일부 제조회사의 튀김어묵류에서는 전분함량이 고형물의 절반이상 ($51.8\%$와 $67.2\%$)을 차지하였다. 품질 기준이 되는 전분함량과 각 조직감 특성의 상관성을 분석한 결과 경도와 탄력성이 전분함량과 유의적 상관성 (p<0.01)을 나타내었다. 경도는 전분함량의 증가와 함께 양의 상관성 (p<0.01) 이 있었고 탄력성은 음의 상관성 (p<0.01)을 나타내었다. 따라서 식품공전상에서 연제품류의 분류는 어육함량만으로 하기보다는 전분함량을 규정에 첨가하거나 부수적으로 전분함량에 대한 상관성이 높은 조직감 특성의 규제사항으로 제시한다면 더 나은 제품의 품질관리에 기여할 것으로 생각되었다.

The objective of this study was to compare the quality characteristics of cultured and red sea bream. The color of dorsal muscle was different between wild and cultured red sea bream. Lipid content of the dorsal muscle was higher in cultured fish than in wild one. The contents of moisture and crude protein in cultured fish muscle were almost same as those of wild one. Sensory evaluation of raw fish meat showed that cultured fish had lower preference in appearance, taste and texture than wild one. Especially the texture of cultured raw fish meat had lower preference than wild meat. For cooked fish meat, cultured fish were harder and less juicy than wild fish. These textural differences between wild and cultured meats were confirmed by objective evaluation including the measurements of hardness, springiness, and cohesiveness. Light microscopic observation showed that cultured red sea bream had more lipid in the surface layer near epidermis than wild one. Also more lipid droplet between muscle fibers were observed in cultured red sea bream by SEM.

This paper presents the design and implementation of virtual aquarium by generating 3D models of fishes that are colored by viewers in an aim to create interaction among viewers and aquarium. The virtual aquarium system is composed of multiple texture extraction modules, a single interface module and a single display module. The texture extraction module recognize the QR code on the canvas to get information of the predefined mapping table and then extract the texture data for the corresponding 3D model. The scanned image is segmented and warp transformed onto the texture image by using the mapping information. The extracted texture is transferred to the interface module to save on the server computer and the interface module sends the fish code and texture information to the display module. The display module generates a fish on the virtual aquarium by using predefined 3D model with the transmitted texture. The fishes on the virtual aquarium have three different swimming methods: self-swimming, autonomous swimming, and leader-following swimming. The three different swimming methods are discussed in this paper. The future study will be the implementation of virtual aquarium based on storytelling to further increase interactions with the viewer.
