  • This research was studied to find out the best ingredients for making demi-glace sauce, using the thickening agent with glutinous rice, non-glutinous rice, brown rice, and black rice, and to look into the quality characteristics. The moisture of demi-glace sauce depending on the thickening type was that the roux added cereals was higher than the control. In addition, it was increased depending on the extension of the storage time. The control was the highest on pH and acidity. On variation depending on the storage time, all of the experimental groups showed decrease on pH. Demi-glace sauce with brown rice and black rice roux showed increase of acidity. The DPPH radical was not tended to be decreased in the experimental group, but it was rapidly decreased in the control, depending on the extension of the storage time. Demi-glace sauce with non-glutinous rice was the highest on Hunter's color L value and generally increased according to the storage time. Also demi-glace sauce with glutinous rice was the highest on 'a' value and 'b' value but was decreased according to the storage time. The control was highest on viscosity, and demi-glace sauce with non-glutious and black rice roux were low on the variation of viscosity depending on the storage time. Increment of total bacteria in demi-glace sauce with black and brown rice roux was relatively lower than the control on storage stability test, and demi-glace sauce with brown rice roux got the highest point after swallow, taste and overall of sensory evaluation.

  • The purpose of this study was to determine the most appropriate ratio for burdock glutinous rice Dasik. Burdock glutinous rice Dasik was prepared with different levels of burdock powder (0, 3, 6, 9 and 12%) and the quality characteristics of burdock glutinous rice Dasik were analyzed. Moisture contents of burdock glutinous rice Dasik increased as the amount of burdock powder increased (p<0.001) compared to the control group. The L-value, a-value, and b-value of burdock glutinous rice Dasik showed a tendency to decrease compared to the control group. The sugar content of burdock glutinous rice Dasik increased (p<0.001) with the amount of burdock powder. The hardness and adhesiveness of the glutinous rice Dasik with burdock powder of 6% or less were decreased, but those with 9% or more burdock powder had higher hardness and adhesiveness than the control group. In addition, the cohesiveness, springiness, gumminess, and chewiness of glutinous rice Dasik with burdock powder increased compared to the control group. The DPPH free radical scavenging activity of the glutinous rice Dasik with 9% and 12% burdock powder were higher than that of the control group (p<0.001). In the sensory test of burdock glutinous rice Dasik, the samples added with 3% and 6% burdock powder gained higher preferences, but the evaluations of others were lower than that of the control group. The glutinous rice Dasik with less than 6% burdock powder was highly evaluated, so it is considered as the most appropriate sample.

  • The purpose of this thesis was to develop pumpkin soup with different ratios of ingredients, using high-nutrient sweet pumpkins. P10G0 without sweet pumpkin and glutinous rice powder showed the highest moisture content, whereas, P5G0 whit Cheongdung pumpkin and sweet pumpkin at the same ratio whitout glutinous rice powder showed the lowest moisture content. For chromaticity lightness of control pumpkin soup scored the lowest. Lightness of P10G0 without sweet pumpkin and glutinous rice powder also scored the lowest. For redness, the P5 group with Cheongdung pumpkin and sweet pumpkin at the same ratio scored the highest while the P10 group without sweet pumpkin scored the lowest. As for yellowness, increased ratio of glutinous rice powder in pumpkin soup scored resulted in reduced yellowness in all groups P5 (p<0.01), P7 and P10 (p<0.001) A higher ratio of Cheongdung pumpkin was thus generally associated whit reduced yellowness (p<0.001). For the spread-ability, higher ratio of sweet pumpkin to Cheongdung pumpkin resulted in significant reduction of spread-ability. However, groups with 12% glutinous rice powder showed no significant differences. Spread-ability of the P5 and P10 groups significant increased and thereafter decreased according to the addition ratio of glutinous rice powder, viscosity of the G0 and G4 groups decreased according to the addition ratio of Cheongdung pumpkin, whereas they first decreased and then increased in the G8 and G12 groups. All groups showed increased viscosity whit more glutinous rice powder. For the sensory evaluation, P5G8 was mostly preferred in all aspects. P7G4 was superior in all aspects except for flavor. P10G4 scored the highest in all aspects except viscosity. For acceptance test, except for the control group, P7G4 whit added of 70% Cheongdung pumpkin, 30% sweet pumpkin and 4% glutinous rice powder was the most preferred in all aspects except color (gloss, viscosity, flavor, taste and overall quality).

  • Mulberry Leaf (Morus-alba) is effective on reducing blood sugar increase and cholesterol in the blood. The objective of this study is to elucidate the sensory and physicochemical attributes of Mulberry Leaf Boogag with different amounts of glutinous rice paste and ginger juice. Mulberry Leaf Boogag, steamed for 90 seconds, was made by puffing the glutinous rice paste and ginger juice. The ratio of glutinous rice paste is made of a double, quintuple, and octuple proportion of water to the weight of the glutinous rice paste. The ratio of ginger juice is at a rate of one, three and five percent. According to the sensory evaluation, hardness and crispiness increased as the glutinous rice paste did, and ginger flavor, bitterness and sourness increased as the ginger juice did. Optimal conditions(p<0.05) were set when the value of hardness was more than five, and the value of bitterness and bitingness, lower than five. The optimal condition of Mulberry Leaf Boogag was established when the ratio of water to glutinous rice paste was 5.5, and in addition, 3.75 percent of ginger juice must be in proportion.

  • This study was carried out to establish a method for the detection of irradiated glutinous rice by measuring pulsed photostimulated luminescence (PPSL) and viscometric properties. Viscosity was determined using a Brookfield DV-III rotation viscometer at 3$0^{\circ}C$ and measured at 30, 60, 90, 120, 150, 180, and 210 rpm. All irradiated samples indicated a decrease in viscosity with increasing stirring speeds (rpm) and irradiation doses. Treatments with 2∼5 kGy significantly decreased the viscosity. The photon counts of the irradiated glutinous rice were measured by PPSL and the photon counts of the non-irradiated and irradiated glutinous rice measured immediately after irradiation exhibited an increase with increasing irradiation dose. The photon counts of irradiated glutinous rice almost disappeared with the lapse of time when stored under normal room conditions, but was still possible to detect after 12 months of darkroom storage. Consequently, these results indicate that the detection of irradiated glutinous rice is possible by both viscometric and PPSL methods.

  • This study was carried out to compare the cooking and antioxidant characteristics of rice containing varying amounts of glutinous rice and cooked by two methods. Rice containing glutinous rice was cooked by general and high-pressure cooking methods with and without fermented alcohol. Pasting characteristics of cooked rice were decreased with increasing amounts of glutinous rice. The water binding capacity and swelling power were significantly decreased with increasing amounts of glutinous rice; however, water solubility indices were significantly increased. Palatability characteristics of cooked rice containing glutinous rice were similar to those of cooked rice without glutinous rice. Total polyphenol contents of cooked rice containing glutinous rice and fermented alcohol were quite different, but this difference was not significant. Total flavonoid contents were increased with increasing amounts of glutinous rice. Total flavonoid content by general cooking method for rice containing 20% glutinous rice and fermented alcohol was $23.20{\pm}0.61{\mu}g\;CE/g$. DPPH radical-scavenging activities for samples with and without glutinous rice were 2.97-5.19 and 3.19-5.45 mg TE/100 g, respectively. ABTS radical-scavenging activity by high-pressure cooking method for rice containing 20% glutinous rice and fermented alcohol was $19.48{\pm}0.63mg\;TE/100g$. In this study, cooking and antioxidant characteristics of cooked rice containing glutinous rice generated data useful for manufacturing processed products.

  • Glutinous rice cake(Chalduk) was made by varying the hours of soaking time of glutinous rice in the water(0, 4, 8, 12, 24 hours). After storage for various periods, the sensory and physical characteristics and the degree of gelatinization were examined in order to determine the effect of glutinous rice soaking period on the quality of Chalduk. The results of the study are summarized as follows. In the sensory test, 8-hour water soaking produced the significantly highest score for salty taste, while 0-hour water soaking had the lowest score. Four-hour water soaking had the significantly highest score for the degree of chewiness. Eight-hour water soaking had the significantly highest score for overall desirability. For the moisture content of Chalduk covered with bean flour, 8-hour water soaking produced the highest moisture content but the difference was not significant. For the degree of gelatinization, 8-hour water soaking had the highest maltose content, which confirmed the suitability of 8-hour water soaking glutinous rice. Eight-hour water soaking had the lowest hardness. With increasing storage period, the hardness sharply increased. Elasticity was higher for the long-period immersed samples than for the non-immersed samples. In conclusion, an 8-hour soaking time for glutinous rice in water was proposed to maximize the Chalduk quality.

  • Studies were carried out to investigate physicochemical properties of taro during the pretreatment process of making Toranbyung. Seventeen kinds of amino acids were found in taro. Aspartic acid and glutamic acid were most plentiful among those amino acids. Essential amino acids were about 42.7% of the total amino acids. Sulfur containing amino acids, mehtionine and cystine were about 2.7% The amylograph indicated that the initial temperature triggering gelatinization of both rice flour mixed with taro and glutinous rice flour mixed with taro increased as the amount of taro increased. But the maximum viscosity of rice flour mixed with taro did not increase as the amount of taroincreased while the maximum viscosity of glutinous rice flour mixed with taro increased as the amount of taro increased. And the peak temperature of both rice flour mixed with taro and glutinous rice flour miced with taro increased as the amount of taro increased. The alkali degree of insoluble ash was higher than that of soluble ash. Glutinous rice dough had more total sugar than rice dough. Yellowness of rice dough was higher than that of glutinous rice dough.
