This research was conducted to enhance the value of low quality sweet persimmon by processing paste by combining low quality sweet persimmon and red-bean. In order to make sweet persimmon paste containing red-bean, the following procedures were executed : 1) the sweet persimmon was cleaned by water 2) the fruit stalk was removed 3) it was peeled, sliced, pitted and crushed 4) steamed and peeled red-bean paste was mixed 5) sweetening materials(starch syrup, sugar and dextrin) and salt were mixed 6) boiled and stored in refrigerator. Sweet persimmon was peeled, stem and seed was removed to make the paste. When mixing sweet persimmon paste and red-bean paste in the ratio of 6 : 4, sensory point of taste and overall desirability were higher than mixing in 5 : 5 and 4 : 6 but texture was lower. The sweet persimmon paste containing red-bean was softened and the sugar content was increased from 41.4$^{\circ}$Brix to 53.1$^{\circ}$Brix when 10% dextrin was added. The overall sensory evaluation was higher in sweet persimmon paste containing red-bean than commercial red-bean paste when 10% dextrin was added. The overall desirability also shown a significant difference between them. Even though findings were statistically insignificant, sweet persimmon powder with red-bean paste increased in texture and overall desirability compared with commercial red-beans paste. Sweet persimmon powder paste containing red-bean significantly decreased in flavor, color, taste and overall desirability compared with sweet persimmon paste containing red-bean. As a result of this study, the best combination for the quantity of sub-materials to make sweet persimmon paste was 600g of sweet persimmon, 400g of red-bean, starch syrup 120g, sugar 60g, salt 4g and dextrin 100g.

Chou-cream bread and Red bean paste bread were made by sponge & dough method with the sweet dough formula. The bread quality was studied by the measurements of the temperature variation, the fermentation level of frozen dough in the special condition(dough conditioner of 5$^{\circ}C$, 10$^{\circ}C$, 15$^{\circ}C$, 20$^{\circ}C$ and 30$^{\circ}C$), the product volume and thesensory evaluation with frozen dough thawed, fermented and baked. When thawing temperature was low, the core temperature of frozen dough increased slowly and the time for thawing and fermentationwas long. In thawing and fermentation, the core temperature of Red bean paste dough increased faster than that of Chou-cream dough. When the thawing conditions of dough conditioner(retarder) were 20$^{\circ}C$ and 30$^{\circ}C$, the level of total time decrease for thawing and fermentation was 55 and 86 min in Chou-cream dough and 62 and 90 min in Red bean paste dough respectively in comparison to dough conditioner of 5$^{\circ}C$. In volume of baked products, they showed no significant difference for three weeks of storage, but slight difference for four weeks of storage. The result was that Chou-cream bread was larger than Red bean paste bread in the decrease of volume. In sensory evaluation, the bread quality became low according to the time. When stored for four weeks in the freezer, significant differences were found in Chou-cream vread, but slight difference appeared in Red bean paste bread. The research identified that Red bean paste dough was more effective in manufacturing time than that of Chou-cream dough, when thawing temperature was high, and if frozen dough was thawed in the retarder of lower than 20$^{\circ}C$, the bread quality in terms of volume and sensory evaluation had no significant difference in comparison to the none-freezing Red bean paste bread.

The effects of five colored soybean (blue, red, yellow, white, and black) varieties on the quality characteristics of soybean paste (Doenjang) were investigated for proximate composition, salt content, pH, color, organic acid content, amino acid content, and mineral content after 80 days of aging. Soybean paste (Doenjang) samples were divided into TDS (traditional Doenjang prepared with soybean) and TDM (traditional Doenjang prepared with mixed soybeans, kidney bean, black soybean, kind of small bean, sword bean, green bean, red bean, at a radio of 1:1:1:1:1(w/w)). Moisture content was 49.66% for TDM and 49.52% for TDM. Protein and salt contents of the TDS sample were higher than those of TDM. The "L" values of the TDB sample increased the aging period was decreased. In contrast, the "L" and "$\alpha$" values of TDM did not show any significant differences. The main organic acids detected were malic acid > lactic acid > tartaric acid in the TDS and TDM samples. Glutamic acid contents were 2.83 g/100 g for the TDS sample and 2.15 g/100 g for the TDM. The levels of K, Mg, and Ca of the TDS sample were higher than those of TDM. No significant difference occurred between TDS and TDM regarding their quality characteristics after 80 days of aging. Further studies needed include sensory evaluation and functionality of soybean paste made from mixed soybean materials.

This study was conducted to optimize the conditions of a sweet rice paste as a replacement of red bean paste recipe using the central composite design of response surface methodology (RSM). Ten experimental recipes with two reference points (rice flour and sugar), were selected, and the physical and sensory characteristics of a sweet rice paste were measured. In the Rapid Visco Analyzer test, breakdown value was the highest in rice flour (105.73 RVU). Sweetness significantly increased with addition of sugar contents (p<0.0002) and viscosity increased with addition of rice flour contents (p<0.0185). Moisture contents decreased with increasing contents of rice flour and sugar, whereas yellowness and redness tend to increase. In the sensory evaluation test, quadratic models for color (p<0.01865), sweetness (p<0.0399), thickness (p<0.0073), and overall acceptability (p<0.0249) were approved as independent for the rice flour and sugar contents. In conclusion, the optimal mixing ratio of sweet rice paste was determined to be 45.38 g of rice flour and 77.95 g of sugar.

Azuki bean is the important bean crop in Korea, and is traditionally used as a filling material for red bean porridge, rice cakes, and bread, as well as for sediment. So far, the National Insititute of Crop Science has developed azuki bean varieties for various uses, such as for sediment, tea, and azuki bean sprouts. Among azuki bean elite lines, 25 strains were used to analyze the correlation between red bean quality characteristics and sediment yield. The crude protein of red beans was 25.0-28.9%, ash content was 3.8-5.3%, and fat was 0.4-1.0%. As for the appearance quality characteristics of azuki bean, one hundred seed weight was 11.1-19.5 g, the length of seed was 6.45-8.49 mm, the width seed was 4.84-6.45 mm, and the withd/lenght ratio was 0.72-0.89. When the azuki bean were boiled, the thickness of the seed coat was 0.14-0.27 mm and the length ratio of seed was 0.65-0.76 mm, showing that the length of seed was slightly larger than the width. The yield of azuki bean sediment was 239-284% for whole red bean paste, and 144-203% for fine azuki bean paste. As a result of analyzing the correlation between the quality characteristics of azuki beans, such as protein, husk and seed weight, and the yield of azuki bean sediment, the yield of whole azuki bean sediment showed a negative correlation with the seed coat thickness and the length ratio of the original grain at -0.62 and -0.45, respectively. The yield of fine sediment showed a negative correlation with the length ratio of whole azuki beans at -0.49, and a positive correlation with that of white beans at 0.41. However, protein and ash content did not show any correlation with sediment yield. In view of the above results, it is thought that it would be better to have a high seed weight or a low width/length ratio of seed to develope azuki bean cultivar for sediment.

전분입자의 크기는 동부와 녹두가 좀 작았으며, 강남콩과 팥은 약간 더 컸다. 아밀로오스 함량은 녹두와 강남콩이 시료 중 약간 더 많았으나 모두 $25{\sim}29%$의 범주였다. 강남콩전분의 팽윤력은 전 온도범위에서 다른 시료에 비해 아주 낮았다. Brabender Visco/amylo/Graph 결과는 동부, 녹두, 팥은 호화 점도도 크고, 노화시점도의 증가도 크지만, 강남콩은 점도의 증가가 아주 낮았다. 아밀로그램에서 점도의 변화양상은 아밀로오스 함량과는 관계가 없고, 아밀로오스의 크기나 전분립의 형태, 결정화 정도 등에 더 밀접한 관계가 있었다. DSC에 의해 조사한 호화 양상에서 강남콩이 호화 개시온도가 다른 시료보다 더 높았으며 동부와 녹두는 대체로 낮은 편이었으나 이들의 호화엔탈피는 거의 비슷하였다. 이상의 결과에서 동부와 녹두전분의 특성은 거의 유사하였으며, 강남콩은 이들과 많은 차이를 보였고, 팥은 중간적 특성을 나타냈다.
