The effects of the addition of germinated soybean powder on Injulmi characteristics were investigated in this study. Injulmi was prepared with five different levels of germinated soybean powder (0%, 4%, 8%, 12% and 16%)and the physical properties were examined. The moisture content decreased, while the protein, fat and ash contents increased With increasing germinated soybean powder content. Total isoflavone contents, 3.39${\sim}$15.35 mg% before cooking, slightly increased to 3.94${\sim}$15.96 mg% after cooking. Genistin, genistein, daidzin and daidzein, which are blown to be the major functional isoflavones, accounted for approximately 93% of total isoflavone contents. The color of Injulmi darkened slightly and became greenish yellow with the addition of germinated soybean powder. Textural profile analysis showed that hardness and gumminess increased, but cohesiveness and springiness decreased with increasing germinated soybean powder level. Sensory test showed that Injulmi prepared with up to 8% added germinated soybean powder was evaluated as being equally acceptable as Injulmi without germinated soybean powder.

본 연구에서는 우수한 영양과 기능성을 가지는 발아콩가루를 밀가루에 다양한 수준(0%, 4%, 8%, 12%, 16%)으로 첨가하여 식빵을 제조하고 그 품질 특성을 살펴보았다. 수분 함량은 발아콩가루 첨가구와 대조구간에 큰 차이가 없었고 조단백질, 조지방, 조회분 함량은 발아콩가루 첨가구가 대조구보다 유의적으로 높았다. 식빵의 무게는 발아콩가루 첨가량의 증가에 따라 증가한 반면, 부피, 높이, 비용적, 반죽수율은 감소하는 경향을 보였다. Crust의 L값과 b값은 발아콩가루 첨가량이 증가할수록 감소하였고 a값은 16% 첨가구를 제외하고는 대조구보다 높게 나타났다. Crumb의 경우 L값은 첨가구가 대조구보다 낮은값을 나타냈고 a값은 발아콩가루 첨가량 증가에 따라 (-)값이 감소하는 경향으로 나타난 반면에 b값은 증가하였다. 경도, 탄성, 검성 및 깨짐성은 발아콩가루 첨가량이 증가할수록 증가하였고 응집성은 차이가 없었다. Isoflavone의 함량은 baking 전보다 baking 후에 모든 첨가구에서 증가하는 것으로 나타났으며 aglycone의 총 isoflavone에 대한 비율도 가열 후 급격히 증가한 것으로 나타났다. 관능검사 결과 껍질색, 내부색, 냄새, 고소한 맛, 경도는 발아콩가루 첨가구가 대조구보다 강하게 나타났고 촉촉한 정도는 시료간에 유의적인 차이가 없었다. 전체적인 바람직성에서는 대조구와 4% 및 8% 첨가구에서 유의적인 차이가 없이 나타난 반면 12%와 16% 첨가구는 대조구보다 관능성이 저하되는 것으로 나타났다.

The effects of raw and processed small black soybean powders on dietary fiber content and gastrointestinal function in rats were investigated. The crude oil, protein, and ash contents of raw small black soybean powder were not significantly different from those of processed small black soybean powders. The germination process increased soluble and insoluble dietary fiber contents significantly, as compared to raw small black soybean powder. The germinated small black soybean powder diet led to a significantly different food intake than the basal diet in both normal and loperamide-induced constipated rats. The body weight gains of the experimental groups, however, were not significantly different from that of the basal diet groups for both the normal and loperamide-induced rats. The gastrointestinal transit times and fecal weights for normal and loperamide-induced rats consuming the processed small black soybean powder diet were significantly different from those on a basal diet. These results suggest that the processes of cooking and germinating the small black soybean might contribute to acceleration of fecal excretion in both experimental normal and constipation model rats.

Microbiological populations and the sterility of commercial powdered products treated with gamma irradiation at 0~10 kGy were investigated before using them as ingredients for a non-cooked Saengsik product. We evaluated a total of 14 powdered products: 8 powdered cereals, 3 powdered tubers, and 3 powdered leafy vegetables. The total numbers of bacterial populations in non-irradiated powdered cereals, tubers, and leafy vegetables were 2.7~6.9, 5.6~6.0, and $5.3{\sim}6.8\;log\; CFU{\cdot}g^{-1}$, respectively. Moreover, coliform bacteria were not indicated in adlay, millet, germinated brown rice, soybean, and mulberry leaves powder within detection limit ($2.0\;log\; CFU{\cdot}g^{-1}$). The number of Bacillus cereus exceeded $3.0\;log\; CFU{\cdot}g^{-1}$ (the maximum limit for Saengsik products) in all samples, excluding perilla seeds, buckwheat, barley, oat, potato, and Jerusalem artichoke powder. However, a dose of 6 kGy of gamma irradiation reduced the microbiological populations in all samples, and all the powdered products met the microbial requirements for Saengsik products. Futhermore, it was confirmed that all microorganisms in the 9 powdered products, except fermented brown rice, sweet potatoes, and 3 leafy vegetables, were sterilized by 10 kGy of gamma irradiation.
