This study evaluate the quality characteristics and antioxidative properties of acorn mook containing seoritae powder(0%, 2%, 4%, 6%). Among them the results of moisture content, Hunter color system, Texture, and antioxidant activity by making a section different Acorn Mook. The moisture content of samples 70.83%~81.77%, as the Seoritae powder Level in the formulation increased. As the Seoritae powder Level in the formulation increased, L-value of samples decreased, a-value of samples 7.29~7.79 increased and b-value decreased. According to the texture evaluation results, as the Seoritae powder level in the formulation significant decreased, the hardness, adhesivness, chewiness and cohesiveness, chewiness of acorn mook decreased. Seoritae powder level in the formulation increased Total phenol contents increased, Total flavonoid contents, DPPH free radical scavenging activity and ABTS radical scavenging activity of acorn mook decreased. The sensory results, the 2% samples received high taste, color, elasticity, chewiness, overall acceptability scores. In addition the 4% added samples of Seoritae powder showed a good overall evaluation compared to the control samples, so if acorn mook is manufactured by adding 2%~4% of Seoritae powder, it is thought that there is a possibility of commercialization of Seoritae acorn mook. We have the above results adding Seoritae powder to make a traditional food mook will help to use it as basic data for making acorn mook with excellent antioxidant activity.

The goal of this study was to develop an optimal formula for cookies containing soybean/seoritae, Hwanggum, and isomalto-oligosaccharide using response surface methodology to achieve a blood glucose lowering effect. The model showed a good fit with the experimental data [$R^2=0.92$ (soybean) and 0.93 (seoritae)]. However, the p-value of lack of fit was less than 0.05 and ridge analysis was used to determine an optimal formula. The estimated optimal conditions were as follows: soybean cookie: 68.7% soybean, 2.5% Hwanggum, and 75.2% isomalto-oligosaccharide; seoritae cookie: 56.5% soybean, 3.8% Hwanggum, and 56.2% isomalto-oligosaccharide. The area under the curve and glycemic index were significantly lower in the soybean cookie group than in the control. The glycemic load (GL) index of the soybean (19.9) cookie was in the range of a low-glycemic food (<20 GL). These results can be applied to develop a cookie with a blood glucose lowering effect.

We compared the ingredients present in freeze-dried ground food samples with those present in hot air-dried and ambient ground food samples to optimize processing conditions for preserving nutrients in and for improving the ingestion of different foods. The freeze-dried ground sample of black bean showed 4.57% higher retention rate than the ambient ground sample of black bean. Mineral content was also significantly different between these two samples. Moreover, the freeze-dried ground sample of black bean contained 11.54% higher content of ${\beta}$-carotene, a precursor of vitamin A, than the ambient ground sample of black bean. Total anthocyanin content was 453.49 mg in the freeze-dried ground sample of Aronia compared with 158.98 mg in the ambient ground sample of Aronia. Contents of ${\beta}$-carotene and niacin increased by 129.47% and 439.39%, respectively, in the freeze-dried ground sample of grapefruit. Retention rates of proteins, carbohydrates, and niacin were 107.74%, 103.87%, and 156.52%, respectively, in the freeze-dried ground sample of germinated brown rice. Protein digestibility increased by 120.5% and 101.14% in the freeze-dried ground samples of Aronia and black bean, respectively, but did not increase in the freeze-dried ground samples of grapefruit and germinated brown rice.

The objectives of this study were to investigate the physicochemical characteristics of soybean leaves in different cultivars and to develop a soybean curd prepared with soybean leave powder as a functional food. Four cultivars (Daewonkong leaf, Daepungkong leaf, Hwangguemkong leaf, and Seoritae leaf) were selected for this experiment. A significant difference was observed in the proximate composition of soybeans leaves (p<0.05). Soybean leaves had the highest content of carbohydrates. The mineral composition and isoflavone content in soybean leaves were significantly different among the cultivars (p<0.05). In particular, Daepongkong leaf had the highest content of genistein, daidzein, and total isoflavones. This study was also conducted to determine the quality characteristics of a soybean curd developed from daepongkong leaf with various concentrations (0, 0.1, 0.2, and 0.3%) of soybean leaf powder (SLP). The soybean curd yield rate increased according to the level of SLP added, whereas the L and a color values decreased. In the sensory evaluation, intensity scores for color, after taste, leafy taste, and chewiness were highest for the 0.3% soybean curd. The soybean curd with 0.2% SLP soybean milk attained the highest overall acceptability score. These results showed that soybean leaf was preferred over soybean curd containing 0.2% soybean leaf powder.
