  • 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.

  • 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.
