This study was to compare the effects of soy hot water extract, soy slurry, defatted soy flour, soy protein concentration and soy protein isolate on the quality of Busuge Base. In Busuge Base preparation the addition of soy products, in general, showed the improvable effect in the quality of Busuge Base. Among them the soy slurry was especially effective in volume increasing, hardness and panel score, and the soy protein isolate was effective in the protein fortification of Busuge Base. In addition, the qualify of Busuge Base was best when soy slurry and soy protein isolate were jointly used. In this case, the adequate amount of soy protein isolate was about 10%.

This study was to evaluate effects of agar, sodium alginate and carrageenan on quality of Yugwa(Busuge) base. In the base preparation agar, sodium alginate and carrageenan were added 0.0, 0.1, 0.5, 1.0 and 3.0%(w/w), respectively. Volume, shape, hardness, color(L, a and b value), crude lipid content and sensory evaluation(taste and crispness) of the Yugwa base was measured. Volume of the base was higher than control in case of 0.1-0.5%(w/w) agar, sodium alginate and carrageenan, of which sodium alginate was the highest. Shapes were similar to control. Hardness and crude lipid content was decreased proportional to amount of addition of the three seesweed polysaccharides, the whiteness(L-value) was increased but the yellowness(a-value) and the redness(b-value) decreased. Taste and crispness were increased in the case of 0.1-1.0%(w/w) of sodium alginate, but agar and carrageenan decreased.

Busuge is conventional snack food in Korea which is made from steeped glutinous rice. The effect of the steeping time on total acidity, viscosity, canons, phosphorus and raising power of glutinous rice was investigated. Total acidity was increased from 0.3 to 1.02% by steeping for 20 days at $10^{\circ}C$. Viscosity was increased from 25.5 to 32.4 cP after 14 days steeping and thereafter decreased to 23.5 cP. K, Na, Ca, Mg and P were leached 68, 67, 85 and 16% on 20 days steeping, respectively. K, Na and P were leached in the initial period, and Ca, Mg in the middle period of steeping. Raising power was increased according to the acidity increase and leaching of Ca, Mg and inorganic phosphorus during steeping. However, influence of the former on raising power was greater than the after.

The shelf-life of Yugwa(Busuge) is very short because of the low oxidative stability of soybean oil which is conventionally used as the frying oil of Yugwa base with high porous structures. To identify the possibility of replacing soybean oil with palm oil whose oxidative stability is high, POV(peroxide value), AV(acid value), colorness (L. a and b), hardness and sensory characteristics during storage of the Yugwa base fried with the soybean oil and palm oil stored in the anaerobic packaging or the aerobic packaging at 10 and $30^{\circ}C$ for 75 days were measured. POV and AV of the Yugwa base fried with palm oil were significantly lower than those of Yugwa fried with the soybean oil. Hardness and colorness were not different each other and, sensory evaluation was slightly higher than that fried with soybean oil. Lipid absorption amount was not significantly different between the Yugwa base fried with palm oil and the one fried with soybean oil.
