Six kinds of spirulina added dressing $(0\~1.09\%)$ were prepared and their rheological, physical and sensory characteristics were evaluated The hardness and adhesiveness of spirulina-added salad dressing were increased with the added amounts of spirulina. Viscosity of spirulina-added salad dressing was not significantly different up to $0.28\%$ whereas that of dressing added more than $0.55\%$ spirulina significantly increased, compared with that without spirulina. Emulsion stability of all of spirulina-added salad dressings was $40\%$ Antioxidant activities of spirulina-added salad dressing increased with spirulina increased: $IC_{50}$ values of DPPH radical scavenging activity and lipid peroxidation inhibition activity of $0.28\%$ added-dressing were 104.98 mg/mL and $6.71{\mu}g/mL$ of TBARS, respectively, which were higher than those of mayonnaise. The fat globule size of $0.28\%$ spirulina-added salad dressing was distributed within $0.5\~4.0{\mu}m$, of which $85.6\%$ of total fat globules were consisted of the size of less than $1.5\{\mu}m$. Total microbial number of salad dressing was 6.2log(CFU/mL), but E coli was not detected Sensory preference test of spirulina-added salad dressing showed that scores of appearance, flavor, viscosity and over-all preference for $0.28\%$ added-dressing were the highest with 7.83, 7.50, 5.33 and 7.97, respectively. Based on these results, spirulina-added salad dressing might have heath promoting effect showing antioxidant activity, and the most appropriate concentration of spirulina for salad dressing was $0.28\%$.

The effects of spirulina-added salad dressing on lipid profiles and antioxidant biomarkers such as total glutathionine, TBARS value, carbonyl value, GPx, GR, SOD and paraoxonase activity in plasma or liver of mice were evaluated Sixteen male ICR mice weighing 20$\pm$2 g were divided into two groups and fed low fat ($5\%$ fat) diet (low fat control: LFC) and low fat control plus dressing diet (LFD) for eight weeks. Body weight, tissue weights of liver, heart and kidney, and the distribution of body fat deposition were not significantly different between two groups. Also, the profile of TG, TC, LDL and HDL cholesterol were similar between two groups. The DNA damage was determined using the comet assay (single cell gel assay) with alkaline electrophoresis and quantified by measuring tail length (TL). Spirulina salad dressing consumption resulted in significant decrease in lymphocyte DNA damage expressed by TL (LFC: $28.8{\mu}m$, LFD: $20.3{\mu}m$). Additionally, salad dressing consumption for 8 wks decreased the lipid peroxidation assayed by TBARS to $12.6\%$ compared with the control. The levels of antioxidant vitamins such as $\beta$-carotene were significantly higher in plasma of LFD group than those in LFC group based on HPLC method This study shows that spirulina-added salad dressing exerts degenerative disease-protective effects on oxidative DNA damage and lipid peroxidation possibly via a free radical levels.

스피루리나 첨가 저지방 샐러드 드레싱을 $5^{\circ}C$ 또는 $10^{\circ}C$에서 저장하면서 품질 특성을 분석하였다. 드레싱의 점도는 저장 2주후부터 저장기간이 경과됨에 따라 감소하였으며, 저장온도에 따른 차이는 없었다. 유화안정성은 제조직후의 $40\%$에서 저장기간이 경과됨에 따라 감소하여 저장 8주후에는 $25\%$정도 감소하였으며, 저장 온도에 따른 유의적인 차이는 없었다. 지방구의 입자 크기는 저장 30일까지는 제조직후에 비하여 큰 차이가 없었으나 저장75일 후에는 가장 작은 크기인 $0.5{\sim}1.0\;{\mu}m$는 $11.3-13.5\%$로 제조 직후의 $25.5\%$에 비하여 크게 감소한 반면에, 입자가 큰 $1.5-2.0\;{\mu}m$의 경우, 제조직후의 $11.4\%$에서 $30.1-32.3\%$로 크게 증가 하였다. 색상은 샐러드 드레싱을 저장하는 동안 명도(L 값)는 감소하였고, a 및 b 값이 증가하는 경향을 나타내었다. 저장온도가 높고 저장기간이 길수록 지질산패도는 증가하였고 저장 온도가 높을수록 TBARS 값은 증가되었는데 $5^{\circ}C$의 경우는 $11\%$, $10^{\circ}C$의 경우는 $15\%$ 증가되었다. DPPH 라디칼 소거능은 $5^{\circ}C$에서 저장하여 8주 경과된 샐러드 드레싱의 $IC_{50}$값은 157.4 mg/mL 이었고, $10^{\circ}C$에서 저장하여 8주 경과된 샐러드 드레싱은 194.6 mg/mL로 저장 기간이 경과됨에 따라 $IC_{50}$값은 증가되었다. 제조직후의 총균수는 6.2 log(CFU/mL)이었고 저장 4주후에는 증가하여 7.3-7.5 log(CFU/mL)이었고 저장 8주 후에는 7.9 log(CFU/mL))로 증가하였다. 그러나, 유해미생물인 대장균군은 저장 8주후까지 검출되지 않았다. 이상의 결과로부터 스피루리나 첨가 샐러드 드레싱의 품질유지를 위해서는 저온 저장이 바람직하였다.

Spirulina is known to be more useful abroad than in Korea because it contains more protein than Chlorella, the same microalgae. In the past, sources of animal protein were diverse, but since it takes a long time to receive protein along with environmental pollution, we thought that spirulina could attract attention as a new protein source. In this study, application cases were analyzed in foods in the fields of acorn cake, tofu, dumpling skin, fish cake, white bread, pound cake, salad dressing, and yogurt and so on. As a result of centrally analyzing antioxidant and sensory evaluation, it was confirmed that the results were effective enough to develop products in tofu, dumpling skin, fish cake, and pound cake. It is thought that development of food in other fields will be possible if an additive amount that can match the consumer's preference is found by supplementing the mixing ratio. If it is used as a main raw material for existing food rather than as a raw material for health functional food, consumer preference can increase and quality can be further improved, and it can be suggested as a good alternative for an aging society.
