This study was conducted to confirm the effect of drying method on quality of popped rice for making salyeotgangjung(popped rice lump with malt syrup) in process of drying gelatinized rice. The drying were performed at dry oven or convection oven, at $30^{\circ}C,\;50^{\circ}C\;and\;105^{\circ}C$, respectively. There were not significant differences in the hardness of popped rice among the drying methods. The dry at $30^{\circ}C$ constant in dry oven showed higher popping rate, good external surface, uniformed and well developed internal cell size. The dry at $30^{\circ}C$ in convection oven and $50^{\circ}C$ constant temperature in dry oven showed low expansion and poor external surface, respectively. In conclusion, the drying at $30^{\circ}C$ in non-convection oven had the highest quality of popped rice for salyeotgangjung.

A literatural survey on Hankwa, traditional Korean cookies, was made in order to identify the state of scientific understanding on these products and the future study needs for the modernization of the products. The type of Hankwa varies with the raw materials used and the processing methods and is classified into 7 groups, i.e. Yumilkwa, Ganjung-Sanja, Dasik, Jeonkwa, Suksilkwa, Kwapyun and Yutgangjung. The recipe and processing characteristics of 7 types of Hankwa were discussed and the scientific findings on these products were reviewed.

The effects of steeping time of glutinous rice and of beating time of the cooked rice on characteristics of Ganjung was examined. and the optimum conditions of traditional Gangjung preparation were determined. Moisture absorption of glutinous rice was the maximum at 2 hours of steeping in water and did not increase much after then. pH of the steep water was the lowest at 7 days of steeping and increased slightly thereafter. Reducing sugar content of the steep water increased as the steepting time was extended. Expansion ratio of Gangiung was the greatest with 5 days of steepting, and tended to decrease with longer beating time. Optimum conditions of Gangjung preparation was 7 days of steeping glutinous rice and 4 minutes of beating (40 times/min) the cooked rice.
