This study was carried out to investigate of the quality characteristics of the starch Oddi Dasik(MSOD) manufactured with various addition levels (0, 5, 10, 18 and 28%) of mulberry fruit (Oddi) juice (MFJ), with various levels(55%, 50%, 45%, 37% and 27%) of sucrose syrup, and with the ratio of rice powder: mungbean starch (1:4) according to the traditional Korean Dasik (a kinds of cookie) methodology. The nutritional components of Oddi and MSOD were examined, and sensory evaluation and physical tests of MSOD added MFJ were conducted. The results are summarized as follows. In Oddi, the contents of moisture, crude fat, crude protein, crude ash, and vitamin C, and the levels of acidity, pH and sugar were 88.45%, 0.245%, 2.23%, 0.88%, 53.20 mg%, 8.00%, 4.41 and 11.0 Brix%, respectively. In MSOD (Oddi 10%), the contents of moisture, crude fat, crude protein, and crude ash, were 22.8%, 0.117%, 9.2% and 0.8%, respectively, and were all increased with increasing MFJ amount. In MSOD (Oddi 10%), the contents of Ca, Mg, K and Fe were 63.2 mg%, 70.9 mg%, 376.0 mg% and 7.7 mg%, respectively. and were increased with increasing MFJ amount. For the establishment of the additional amount of MFJ, sensory evaluation and physical tests were conducted. From the total characteristics of sensory evaluation, the MSOD with 10% MFJ was judged as the best. Color L and b values of MSOD significantly decreased and a value increased with increasing MFJ percentage. Hardness, gumminess, adhesiveness and chewiness among the texture characteristics of MSOD were significantly increased with increasing MFJ amount. However, there were no significant differences in springiness and cohesiveness of the MSOD. In conclusion, the optimal added amount of MFJ for the manufacture of the MSOD was proposed to be 10% of the total weight.

The effects of various kinds of starch (mungbean, potato, corn and a blend of potato and com starch) on the quality characteristics of muhwakwa-pyun were studied according to the storage duration. The sweetness, pH and total acidity of muhwakwa extract were analyzed, as were the Visco/Amylograph viscosity profile and DSC thermodynamic characteristics of starches. For quality characteristics, color difference, instrumental texture characteristics and sensory characteristics were compared. The sweetness of muhwakwa extract was satisfactory but the total acidity was low for Kwa-pyun manufacture. Therefore, its pH was adjusted to 3.4 by adding 10％ citric acid with an amount of 1％ of total liquid. From the Visco/Amylograph viscosity profile and DSC thermodynamic characteristics of starches, a blend of potato and com starch was found to be easy to cook and form a gel but a little more resistant than the other starches in terms of retrogradatin. Lightness (L) and yellowness (b) of Kwa-pyun increased while its redness (a) decreased by the storage. The color became whiter and the clarity decrease regardless of the kinds of starch, which became obvious after 3 days of storage. The hardness, springiness, adhesiveness and cohesiveness tended to decrease with storage, which was weak in a blend starch. The overall acceptability of Kwa-pyun made with a blend of potato and com starch was evaluated as being the best among the samples tested. Therefore, for traditional kwa-pyun manufacture manufacture mungbean starch might be replaced with a blend of potato and corn starch which is less expensive and easily available in the market nowadays.

The purpose of this study was to identify mungbean (Vigna radiata L.) cultivars with appropriate characteristics for labor saving culture (whole crop feeding and combine harvesting), and to investigate seed quality in the southern South Korea. Cultivar Dahyeon exhibited strong lodging resistance, excellent disease tolerance, and greater pod numbers per plant resulting in higher yield. Cultivar Owool and Keumseong, the two most common mungbean cultivars in Korea, exhibited lower yield than Dahyeon due to weaker disease tolerance or lower pod numbers per plant. Cultivar Samgang demonstrated higher seed starch content, Jangan, Nampyeong, and Keumseong exhibited higher crude protein content, and Sohyeon exhibited higher vitexin and isovitexin contents. However, no statistical differences were found among the cultivars in crude fat content. Unsaturated fatty acid ranged from 51.8 to 57.2%, with saturated fatty acid ranging from 36.2 to 40.3%. We detected five unsaturated fatty acids including linoleic acid (36.1 to 38.6%), linolenic acid (10.3 to 14.7%), and oleic acid (2.7 to 4.6%), and seven saturated fatty acids including palmitic acid (28.7 to 30.9%), stearic acid (2.9 to 4.1%), and arachidic acid (1.5 to 3.7%). There were significant differences between the cultivars in amylogram properties of seeds: the Nampyeong cultivar exhibited a lower gelatinization temperature; Dahyeon was higher in peak viscosity and breakdown; and Sohyeon, Nampyeong, and Dahyeon were lower in setback.

This study was conducted to identify the sensory characteristics of the Korean traditional confectionery, dasik, prepared under different conditions and to compare their consumer acceptance in Korea. To accomplish this, descriptive analysis of eight samples prepared using two types of rice cake powder, dasik (Rflour, Rflour_Omija), brown rice powder red ginseng dasik (Brice_Ginseng_P), pinepollen dasik (PineP), black sesame dasik (BSesame), bean dasik (Rbean), and two types of mungbean starch dasik (Starch_Omija, Starch_Greentea), was conducted by ten trained panelists. In addition, 81 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale, as well as the perceived intensities of sesame flavor, sweetness, and hardness using a 9-point just-about-right (JAR) scale. Partial least square- regression (PLSR) indicated that the BSesame and Rbean samples, which had significantly (p<0.05) high roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor scores, had the highest acceptability and consumer desire scores. Additionally, the PineP and Rflour_Omija samples, which had relatively high particle size, transparency, roughness, spoiled tofu, fermentation and raw rice flavor scores, were the least preferred samples. Therefore, roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor attributes were considered drivers of "liking" whereas particle size, transparent, roughness, spoiled tofu, fermentation, and raw rice flavor attributes acted as drivers of "disliking" among consumers.

The origin as well as the culinary aspects such as ingredients, types, preparation methods of Dasik and materials and ornamental patterns of Dasik mould(다식판) are discussed and analyzed through the literature survey. 1. The origin of Dasik came from the custom of Umdha(飮茶) together with the Worship of Buddhism(숭불정책) and the abundant production of rice due to the Policy for Agricultural Development(권농정책) of the Koryo Dynasty. 2. The main ingredient of Dasik was rice flour and wheat flour and thereafter, plant materials such as Song-wha(송화), Mungbean starch flour(녹두녹말가루) and Hwang-yul(황율) were followed. Honey, sugar and syrup were used as coagulating agents. Dasik was often colored by the addition of Omija(오미자), a plant material containing red pigment. 3. Originally. Dasik mould was not used until Jeungbo-Sanlim-Kyungje. Major types of Dasik were reviewed from the literature survey. 4. The materials of Dasik mould were wood or porcelain. Their shapes and ornamental patterns were reviewed. Circular design was predominant in the wood and lettered designs were predominant in porcelain. 5. Utilization of Dasik recorded in Koryo-History(고려사) and Chosun-Wangjo Shilloc(조선왕조실록) were reviewed.

Oddi is a mulberry (Morus alba L) fruit which has antiinflammatory and antioxidative effects. This study was carried out to investigate the quality characteristics of Oddi-Pyun which was manufactured with various addition levels (0, 0.5, 1, 2, 4％) of Oddi extract according to the traditional Korean Kwaypun (a kind of jelly) methodology. Oddi-Pyun was made with various levels of Oddi extract, mungbean starch (9％) and sugar (30％). To establish the additional amount of mulberry fruit extract, sensory evaluation and physical test were carried out. From the results of sensory evaluation, the 2％ of Oddi-Pyun was judged as the best in terms of color, flavor, hardness and elasticity. According to texture characteristics (hardness, adhesiveness, springiness, gumminess and chewiness), 1.0％ and 2.0％ of Oddi-Pyun were judged as the best. The contents of Ca (69.50, 74.75, 84.25, 100.60, 183.55ppm), Mg(27.37, 29.38, 34.20, 46.73, 97.45ppm) and Fe (320.23, 572.45, 680.50, 725.95, 906.50ppb) increased with increasing Oddi extract. Therefore, the optimal added amount of extract for the manufacture of Oddi-Pyun was proposed as 2％ to the total weight. It was concluded that this Oddi-Pyun would be helpful to improve the health status of rheumatics and patients with similar diseases.

This study was to investigate the quality characteristics of Seockryu-pyun by addition of different ratio of pomegranate juice and pomegranate concentrate (100%, 80%, 60%, 40%). Moisture and the pH increased as the content of pomegranate juice and pomegranate concentrate decreased respectivley. However, DPPH radical scavenging activity was decreased when adding pomegranate juice and pomegranate concentrate was decreased. With decreasing pomegranate juice addition, both the lightness(L) and yellowness(b) was significantly (p<0.05) higher, whereas, the redness(a) was significantly (p<0.05) lower. As addition of pomegranate concentrate was decreasing that lightness, a value and b value were higher. Texture profiles of hardness, adhesiveness, cohesiveness, gumminess, chewiness of Seockryu-pyun was not greatly showed significant difference among samples. Also, springiness was not significantly (p<0.05) different in any groups. For sensory evaluation, color and sourness were decreased as pomegranate juice and pomegranate concentrate was diluted. Seockryu-pyun, PJ3 made with addition of 60% pomegranate juice was the most preferred in overall acceptability. From the results, the most advisable mixture ratio of Seockryu-pyun was found as pomegranate juice 360 g (60%), water 240 g, mungbean starch 60 g and sugar 200 g.

In this study, dietary fiber contents in cereals and pulses were determined by Mongeau-Brassard method to compare those to the AOAC officied method. The average total dietary fiber (TDF) contents by AOAC official method were 3% for cereals and 21% for pulses. The average ratios of soluble dietary fiber contents to TDF contents were 40% for cereals and 43% for pulses. The differences between TDF values (dry matter basis) by two methods were 0.1%-1.0% for cereals and 1.0-7.0% for pulses. The differences between two methods were caused by residual protein in fiber by Mongeau-Brassard method and by residual starch in fiber by AOAC official method. TDF\\error boundary values by Mongeau-Brassard method were little higher than those by AOAC official method. But seven foods except highly milled rice, brown rice and mungbean were F/Fc>1. Therefore, Mongeau-Brassard method was evaluated as precise as AOAC official method.

This study was performed to determine the relative quality of mungbeans harvested in bulk after applying a labor-saving cultivation (LSC) method, compared to mungbeans harvested three different times under the conventional cultivation condition. There was no significant difference in starch, crude protein, and vitexin or isovitexin content of seed according to the cropping system or harvest time. The mungbeans grown under the LSC method had the highest crude fat content, followed by mungbeans from the third-, the second- and the first-harvest mungbeans under the conventional cultivation. No significant difference was found in the composite ratio of saturated fatty acids to unsaturated fatty acids according to cropping system or harvest time. The second-harvest mungbeans grown under the conventional cultivation condition had 17 different types of fatty acids, while the third-harvest mungbeans grown under the conventional cultivation and those grown under the LSC condition had the fewest types of fatty acids with 12. Of the major saturated fatty acids, palmitic acid and arachidonic acid had the highest composite ratio in the first conventional cultivation followed by the second, the third and the LSC. However, stearic acid showed the opposite tendency. Of the major unsaturated fatty acids, linoleic acid had the highest composite ratio in the first conventional cultivation, followed by the second and third conventional cultivation and the LSC. Amylogram characteristics of the mungbeans were significantly different according to cropping system and harvest times. The mungbeans harvested after the first conventional cultivation had significantly higher pasting temperature, peak viscosity, holding strength viscosity, final viscosity and breakdown, while mungbeans harvested after the third conventional cultivation had significantly higher setback viscosity. In contrast, the mungbeans harvested under the LSC methods had a significantly lower amylogram value. When harvest rate, color values and amino acid content of sprout were measured, mungbeans grown under the LSC conditions had a low harvest rate of sprout, but had Hunter's color values and amino acid content of sprout similar to those of mungbeans grown under the conventional cultivation condition.
