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.

To select the desirable soybean cultivar for chonggugjang processing, the physicochemical characteristics of raw soybean materials and chonggugjang samples were investigated. Eight soybean varieties including Danyeobkong, Danbaegkong, Kwanankong, Pureunkong, Manlikong, Sinpaldalkong 2, Jinpeumkong and Hwankeumkong were used for experiment. On the basis of quality characteristics of raw materials, such as seed coat weight rate, hydration swelling, and the content of fructose, glucose and sucrose, and chonggugjang, such as hardness, ${\gamma}-glutamyltranspeptidase\;({\gamma}-GTP)$ activity, free amino acid content, and amino type nitrogen content, Sinpaldakong 2 and Danyeobkong were desirable soybean cultivars for high quality chonggugjang processing.

Changes in the contents of mevinolins (natural statins, $0-568.18{\mu}g$), coenzyme Q10 (CoQ10, $26.41-65.59{\mu}g$), and tocopherols ($232.80-312.87{\mu}g/g$ dry weight) in Monascus-fermented soybean were determined using HPLC. Significant increases (p<0.05) in mevinolins and CoQ10 were obtained in Monascus-fermented soybean after 20 days of fermentation compared with unfermented soybean (0 days), whereas no significant change (p>0.05), or a slight decrease, in tocopherols was observed. The results indicate that Monascus-fermentation has great potential for enriching mevinolin and CoQ10 in soybeans.

This investigation into unfermented soybeans, which were left from the soybeans used to make cheongguk-jang, was conducted to find out its availability of the application to the environmental-friendly fertilizers. The test of cultivating lettuce, using 1/5000a Wagner pot, was carried out inside the affiliated farm glasshouse, belonged to University of Chung-Nam National. The results showed that in the category of leaf length, the control and cheongguk-jang soybeans treatment plot had similar outcomes and in the category of the extract of the cheongguk-jang soybeans, it increased by about 26~33%. And in the categories of width and number of leaves it showed that the extract treatment increased by about 9~20%, in compared to the control. Finally, in the category of fresh weight, the results showed that cheongguk-jang soybean and the extract of the cheongguk-jang soybean effectively increased by about 9~27%, and that pig manure compost treatment plot with the extract of the cheongguk-jang soybean also significantly increased by about 26%, compared to the control. Accordingly, the unfermented soybean left in the production of cheongguk-jang and the extract of the cheongguk-jang soybean are considerably appeared to be valuable environmental-friendly fertilizers.

동양에서는 예로부터 콩을 중요한 식량자원으로 생각해왔기 때문에 음식에 있어 다양한 형태로 많이 이용되어 왔으며 특히 장류산업에 있어 가장 많은 사랑을 받아왔다. 콩은 주로 각종 식품의 발효원으로 사용되고 있으며 다양한 가공제품으로 출시되고 있다. 동양에서 장류산업이 일찍부터 발달한 이유는 곡류중심의 식단에 따른 부식의 필요성 및 조미원을 찾아야 하는 필연성과 연계되었기 때문이다.

We investigated the effect of black soybean and doenjang with black soybean on production of cytokines including interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) compared with yellow soybean and doenjang with yellow soybean. We also determined inhibitory effect of two types of soybeans and doenjang on tumor metastasis produced by colon 26-M3.1 carcinoma cells. The cytokine productions of mouse splenocytes increased by the exposure of lipopolysaccharide (LPS, 1 ${\mu}g$/ml) compared to without treatment of LPS. The LPS-induced IL-2 production was highest in the black soybean methanol extract, while the methanol extract from black soybean doenjang fermented for 2 mo showed the higher levels of IL-2 without LPS (p<0.05). In case of LPS-induced IL-6 production, the methanol extracts from control, yellow soybean, black soybean doenjang fermented for 2 and 7 mo showed higher levels of IL-6 compared to those of black soybean, and yellow soybean doenjang fermented for 2 mo (p<0.05). The methanol extract of black soybean doenjang fermented for 2 mo showed significantly higher levels of TNF-${\alpha}$ in both with and without LPS (p<0.05). In experiment of tumor metastasis, the treatment (1 mg/mouse) of methanol extract from black soybean doenjang fermented for 7 mo inhibited tumor metastasis by 50% and had the highest inhibitory effect among other samples (p<0.05). From these results, doenjang manufactured with black soybean modulated the production of cytokine and showed anticancer effect, suggesting that this effect was increased with increased periods of fermentation.

In order to utilize health food chick bean as a raw material for cosmetics, the skin improvement effect of a mask pack made of chickpea Natto fermented with Bacillus subtilis Natto strain was studied. Powder obtained by lyophilization of chickpea Natto was applied to a facial mask pack as a paste formulation. This Natto pack was applied to subjects in their 50s and 60s to investigate their effect on skin improvement. As the number of treatments of Natto pack increased, the skin was improved and the improvement effect was remarkable after 4 treatments. After four times treatments, moisture content and sebaceous secretion increased by $8.4{\pm}3.6%p$ and $4.0{\pm}2.3%p$, respectively. Skin pores and wrinkles were also decreased by $1.8{\pm}0.3%p$ and $1.8{\pm}0.9%p$, respectively. Skin pigmentation decreased by $1.3{\pm}0.2%p$ and skin tone also increased from 55.2% to 55.9%. These results indicate that Natto product obtained by fermenting chickpea has the effect of improving skin such as moisturizing, pore, wrinkle, pigmentation, sebum secretion and skin tone, and can be used as a raw material for various functional cosmetics.
