Sikhe a general Korean traditional drink, is a sweet drink fermented with malt powder rice(or glutinous rice). To investigate the perception and use behavior of Sikhe, 35.2% of the male and 64.8% of the female adults in Daegu and Kyungbuk area were surveyed. The methods frequency, percentage, chi-square test and one-way ANOVA were used to analyze the data. The main results were as follows : 36.1% of the participants usually preferred the traditional drinks and 94.7% of them had experienced Sikhe among the traditional drinks. Most respondents liked Sikhe owing to its good taste. In addition, the responses to 7 questions about the Sikhe were also measured on a 5-point likert scale. The statement 'Sikhe is a traditional food' and 'Sikhe is a natural food' received high positive responses and adults in their 50's had a generally better knowledge of Sikhe than the counterparts. furthermore, 54.8% sometimes purchased commercial Sikhe, but 40.7% didn't buy it at all due to bad taste. Therefore, to increase the intake of commercial Sikhe, the taste needs to be improved, and 59.8% of adults suggested that 'Add other ingredients and the taste can be improved', while 58.8% replied 'maintenance' prospects for Sikhe consumption.

The antiulcerative effect of Sikhe(Korean traditional sweet rice drink) on stomach ulcer induced by ethanol treatment was investigated. Fifty male mice were divided into 5 groups consisting of control group and 4 Sikhe groups fed 0.3% commercial Sikhe(group I), 3% commercial Sikhe(group II), 0.3% home-made Sikhe(group III) and 3% home-made Sikhe(group IV). Mice were fed experimental diet ad libitum for 45 days. Growth, stomach surface pH, gastric wall mucosa and ulcer index were examined. Feed intake and weight gain did not show significant differences among 5 groups(p>0.05). The stomach surface pH and the amount of gastric wall mucosa of Sikhe fed groups(group I~IV) were higher than those of the control group, but were not significantly different(p>0.05) . The ulcer indices of the control and Sikhe fed groups were 18.6$\pm$6.58mm and 13.7$\pm$5.87~17.8$\pm$9.10, respectively. But significant differences were not found between the control and the Sikhe fed groups(p>0.05) though mean values of Sikhe fed groups were lower than that of the control group.

To propose quality improvement for commercial sikhe, we assessed the opinion of Food and Nutrition specialists about the status of utilization, preference and quality of commercial sikhe. Questionaires were hand-delivered to 530 subjects consisted of University students and faculties of Department of Food and Nutrition at 8 cities (Seoul, Incheon and Gyeonggi, Daejon and Chungnam, Cheongju and Chungbuk, Daegu and Gyeongbuk, Jeonbuk, Gwangju and Jeonnam, Husan and Gyeongnam) in Korea and the complete data of 328 subjects were statistically analyzed using SPSS Program for Window (mean, $\chi$$^2$, t-test, Pearson's correlation coefficient). Questionaires were consisted of sociodemographics, frequency and occasion of purchasing, opinion of quality and improvement points and sen-sory characteristics. Occasion of purchasing commercial sikhe is in order of ordinary day> for present> special day. Most subjects answered that commercial sikhe was different from home-made one. The reasons not to per-chase were the most in no preference and the next, in seeming to be different taste from home-made one. Points for further improvement in commercial sikhe were in order of taste> amount and floating of rice >flavor. The correlation coefficients between over-all preference and sensory characteristics showed positively in taste (0.54), texture of rice (0.476), content of malt (0.398).

To assess the quality of commercial sikhes, we compared physicochemical and sensory characteristics of commercial sikhe with home-made one. Six different brands and home-made sikhes were analysed for physicochemical (sugar content, acidity, color, viscosity, transparancy, texture of rice) and sensory characteristics (7-point scoring test,18 experienced panel members). Commercial sikhes (6 different companies) exhibited lower sugar content (11.6～12.5$^{\circ}$Brix) and viscosity (5.33～9.33 cP) than home-made one, whereas higher pH (5.93 ～6.87), transparency (9.1～46.5% at 558 m), Hunter L, a and b values. In the texture of rice, commercial sikhe showed higher hardness, springiness and chewiness than those of home-made one in. Sensory evaluation showed that malt and rice content, tex-ture and color of rice, and over-all preference for commercial sikhe was significantly lower than those for home-made one (p<0.05). Especially, the scores of over-all preference for 3 commercial sikhes (2.7～3.6) were much lower than that of home-made one (5.7).
