The purpose of this study was to improve the quality characteristics of soy ice cream supplemented with oligosaccharide, and to test its blood glucose lowering effect. Boiled soybean powder was compared to parched soybean powder and to milk, as an ingredient. The soybean powder base was prepared by incubating with fructooligosaccharide (FOS) and apple juice, along with Lactobacillus acidophilus and L. bulgaricus at $30-40^{circ}C$ for 24 hr. With the fermentation process, the fishy smell of the soybean was removed and the taste improved. The overrun and melt-down values of the boiled soybean ice cream were significantly higher than those of the parched soybean ice cream, although they were significantly lower than those of the milk ice cream. The sensory characteristics of the soy ice cream prepared with the fermented base of boiled soybeans were significantly improved, as compared to those of the ice cream made using parched soybeans, but they were not significantly different from those of the milk ice cream. The blood glucose level at 120 min after ingestion of the ice cream prepared with FOS and the fermented base of boiled soybean powder was significantly lower than that occurring with the milk ice cream made with sugar.

The purpose of this research is to examine the awareness and preference for a variety of Kimchi and Kimchi intake patterns among the students living in Chungbuk province. Four hundred samples, consisting of elementary, middle, and high school students, were surveyed; and a total of 366 usable, completed copies of the questionnaire were used for the research. The collected data were statistically analyzed using SPSS 10.0. The results of the analysis were as follows: First, Kimchi was considered traditional (24.3%), nutritious (20.5%), fermented (l9.2%), and healthy (16.1%). Second, the main reason Kimchi was preferred was its "hot taste" (25.4%), "chewy texture" (17.4%), and "sour taste" (14.0%). The students preferred their Kimchi a little hot, moderately salty, and properly fermented with a moderate amount of seasoning and did not care much about any particular parts of Kimchi. Third, 75.4% of the students ate Kimchi more than twice a day, and 78.0% of the students consumed more than 3 pieces($2.5{\times}3.0cm$) of Kimchi per meal. Fourth, elementary students wanted the school foodservice to develop bite-sized Kimchi while middle school students wanted to eat their favorite parts of Kimchi without the fishy smell. High school students wanted to eat cool and fresh Kimchi. Finally, the students wanted Kimchi to contain the following fruit and vegetables: pears (48.9%), apples (34.2%), and pineapples (30.0%), young radishes (44.9%), turnips (37.5%), and sesame leaves (34.9%). This study concludes that it is necessary to educate young students about traditional Korean food culture, serve them various types of Kimchi, change the service style, and develop new Kimchi recipes to increase Kimchi intake in school foodservices.

Milk is an emulsion, improving texture of surimi mixture and able to suppress off flavors and abnormal tastes. Therefore, this study aimed to identify the effective properties of milk in the preparation of a surimi mixture for 3D printing. The sensory and physical properties of surimi mixtures containing 0%, 20 wt%, and 40 wt% milk were evaluated, where the unheated surimi mixture with added milk demonstrated increased firmness and adhesiveness compared to the negative control group. In addition, the hardness, adhesiveness, gumminess, and chewiness of the mixture containing 40% milk were highest, but springiness, cohesiveness, and resilience were lowest. In the sensory evaluation, as the amount of milk increased, a fishy smell, abnormal taste and texture improved, hardness and preference increased as well. From these results, it was confirmed that a surimi mixture can be prepared with milk to improve its physical and sensory properties for 3D printing when compared to the negative control mixture. In particular, it was revealed that the physical properties and preference of the surimi mixture are best when prepared with 40% milk.
