The purpose of this study was to investigate the instrumental and sensory characteristics of coffee-sulgi(rice cake) with different ratios of the ingredients; coffee(30$m\ell$, 40$m\ell$ and 50$m\ell$ of espresso and instant coffee) and sugar (50g and 75g). A commercial scheme for coffee-sulgi was also investigated. The optimal mixing ratios of coffee-sulgi with added espresso were rice flour 500g, salt 5g, espresso 40$m\ell$ and sugar 75g. Those of coffee-sulgi with added instant coffee were the same. As the sensory intensities of coffee aroma, coffee taste, sweetness, moistness, elasticity, color acceptance for coffee-sulgi and overall acceptance for quality were enhanced, the overall preference for coffee-sulgi was increased. In addition, overall preference was positively correlated with adhesiveness and a-value of instrumental characteristics, but negatively correlated with cohesiveness and L-value. In coffee-sulgi with added espresso, intensities of coffee aroma, browniness, coffee taste, color acceptance for coffee-sulgi, overall acceptance for quality and overall preference were higher than those of coffee-sulgi with added instant coffee. In this point, gourmet coffee-sulgi with added espresso and universal coffee-sulgi with added instant coffee could be differentiated in the coffee-sulgi markets. In conclusion, this study of coffee-sulgi and the differential scheme for the market will be useful to expand rice processing, enhance the intake of rice cakes and provide a reference for the commercialization of rice cakes.

As one of study efforts to develop a food product that can satisfy the taste of modern people and increase the usage of the popular local product of walnut in the region of Chunan, the current study developed a no sugar added functional walnut-sulgi. The walnut-sulgi was manufactured by adding walnut powder into typical sulgi rice cake. While manufacturing the walnut-sulgi rice cake, the health beneficial sugar alcohol ingredient of sorbitol was added instead of commonly used sugar to specialize the walnut-sulgi as a functional rice cake. As the result of such effort, a soft and moist walnut-sulgi was produced. The color of the newly developed walnut-sulgi is white and has a pleasing taste, and its consumer acceptability was higher than the sugar added walnut-sulgi by showing much soft sweetness and textural properties. Considering the facts that sorbitol has a lower glycemic index (GI) than sugar and the content of unsaturated fatty acids that are insufficient in rice cake could be increased, the newly developed sorbitol added walnut-sulgi is thought to be an appropriate functional rice cake that can attractively appeal to obesity and diabetes concerning modern people.

We prepared Tofu-sulgi by adding tofu and then analyzed the final product in terms of its nutritional quality, rheological characteristics and sensory tests. While the calorie quantity of Sulgi with Tofu was relatively low compared to that of Baeksulgi, it contained the dietary fiber, calcium and iron that were not present in Baeksulgi. Since Baeksulgi holds a large amount of carbohydrates, it shows a higher weight due to its dense fiber. On the other hand, Sulgi with Tofu showed a relatively low level of tofu protein despite the increased amount of tofu protein. This demonstrated the soft characteristics of Sulgi with Tofu. Also, the results of the sensory test showed that Sulgi with Tofu exhibited a higher preference than Baeksulgi in terms of its taste, flavor and fiber content. The preparation method of Sulgi with Tofu in this study used the natural grinding of tofu without removing the moisture. Also the use of both non-glutinous and glutinous rice flour that can be obtained easily in the public market, are convenient due to their characteristics of easy storage and no property change. Therefore, the preparation method of Sulgi with Tofu is quite convenient as compared to that of traditional Dduk (Korean rice cake) including Baeksulgi. From the perspectives of nutritional content, rheological characteristics and taste preference, Sulgi with Tofu fared better than Baeksulgi. Considering the overall quality characteristics of Sulgi with Tofu, we believe that the addition of tofu could contribute positively toward the quality characteristics of Sulgi.

This study was conducted to evaluate the mechanical (texture and color) and sensory characteristics of mulberry leaf sulgi (MLS) and lotus leaf sulgi (LLS) that contained different ratios of ingredients. MLS and LLS with final concentrations of 0%, 1%, 3% and 5% of powdered mulberry and lotus leaf respectively, were prepared. The texture characteristics (hardness, adhesiveness, springiness, cohesiveness, gumminess, chewiness), color values (lightness, redness, yellowness), and sensory characteristics (color, flavor, moistness, taste, brittleness, chewiness and after-taste) of the different sulgis were then measured and compared. With the exception of gumminess and chewiness, the texture characteristics of 0% MLS, 1% MLS and 3% MLS were not significantly different. The sensory characteristics of 0% MLS had the highest scores, whereas those of 5% MLS were the lowest for all factors except for brittleness. However, with the exception of chewiness, the scores obtained from 0% and 1 % MLS did not differ significantly. In addition, 1% MLS and 3% MLS were not significantly different from each other. Furthermore, the texture characteristics of 0% LLS and 1 % LLS were not different significantly, although the characteristics of 1% LLS were significantly different from those of 3% and 5% LLS when springiness, cohesiveness, and chewiness were considered. Additionally, the sensory characteristics of 0% LLS and 1% LLS were not significantly different, with the exception of brittleness, and the characteristics of 1% LLS and 3% LLS were not significantly different, with the exception of taste and after-taste.

The purpose of this study is to determine the optimal mix ratio of Maneul-Sulgi and thereby, review its availability as health cake. For this purpose, the ratios of garlic juice and powder were varied with sugar added. As a result of quantitative descriptive analysis, it was found that the more the garlic juice and powder were added to non-glutinous rice, the Garlic taste was stronger. On the other hand, the less garlic powder was added, the cake would taste softer, and the less garlic juice was added, the cake was more chewy and moist. The feeling after swallowing was best when the ratio of garlic juice was $7\%$. As a consequence of surveying the tastes of Maneul-Sulgi, it was found that the less garlic powder was added to non-glutinous rice, the cake was more preferred. It was perceived that the ratio of garlic juice should be $7\%$ for flavor and desirable taste. As a result of testing the mechanic characteristics, it was found that the less garlic juice was used, the cake was more hard, elastic, cohesive, viscose and chewy. The more garlic powder was used, the Adhesiveness was higher. The Overall acceptability of sensory examination for Garlic taste had positive correlation Hardness of sensory examination and mechanical examination for adhesiveness.
