  • The goal of this study was to evaluate the quality characteristics of various beans in distribution. The quality characteristics investigated were proximate composition, color, free sugars, organic acids, amino acids, and minerals. Bean samples analyzed were white soybeans (Glycine max. (L.) Merrill), kidney beans (Phaseolus vulgaris var. humilis), black soybeans (Glycine max (L.) Merr.), black small soybeans (Rhynchosia nulubilis), sword beans (Canavalia gladiata), and green beans (Phaseolus vulgaris). The highest contents of crude fat and crude protein were 17.60${\pm}$0.14% for white soybeans, and 42.38${\pm}$0.15% for black soybeans, respectively. Higher color values compared to the other samples were $L^*$ (64.07${\pm}$0.97) for sword beans, $a^*$ (15.64${\pm}$0.48) for kidney beans, and $b^*$ (22.92${\pm}$0.09) for white soybeans. The highest contents of sucrose, oxalic acid, and malic acid in black small soybeans were 54.23 mg/g, 23.26 mg/100 g and 18.24 mg/100 g, respectively. Xylose, galactose, lactose, malonic acid, succinic acid, and lactic acid were not detected in the soybeans studied, whereas the glutamic acid content of soybeans ranged from 2.68 to 6.18 g/100 g. Levels of K and Mg contents in soybean were higher than those of the other minerals.

  • This study was carried out to determine the effect of cacao bean addition on the physicochemical properties of extruded rice flour. Rice-based cacao beans (0, 20, 40, 60%) were extruded at a die temperature of $130^{\circ}C$, screw speed of 200 rpm, and moisture content of 25%. As the content of cacao beans increased from 20% to 60%, expansion index decreased, while piece density and specific length increased. The water soluble index and water absorption index of the extrudate increased through extrusion cooking. Lightness decreased as cacao bean content increased while redness increased. As the content of cacao beans increased, paste viscosity decreased. Cold peak viscosity was observed in all extrudates of raw roasted cacao beans. ${\alpha},{\alpha}$-Diphenyl-${\beta}$-picrylhydrazyl (DPPH) radical-scavenging activity increased upon extrusion and cacao bean addition. As content of cacao beans increased, non-roasted cacao beans had higher total phenolic contents than roasted cacao beans. This study showed that addition of cacao beans to extruded rice snack improved antioxidant activity.

  • The objective of this study was to investigate the polyphenolic compounds found in different parts of red and black adzuki beans and to determine the contribution of polyphenolic compounds to the antioxidant properties of adzuki beans. Total polyphenolic and proanthocyanidin contents were studied and their antioxidant activities were determined by ferric reducing antioxidant power, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt assay. The highest total polyphenolic content was found in seed coats (26.1~33.9 mg/g), followed by whole beans (6.9~8.0 mg/g) and dehulled beans (3.3~3.4 mg/g). The highest total proanthocyanidin content was also found in seed coat with 26.5~30.7 mg/g. Moreover, seed coats exhibited the highest antioxidant activity regardless of analytical methods. Antioxidant activity was positively and significantly correlated with total polyphenolic content with the exception of dehulled beans, in which there was no correlation with total polyphenolic content. In particular, the highest correlation was found between DPPH and total polyphenolic content (r=0.945, P<0.01) in whole beans.

  • Soybeans ans black-eyed peas, chosen as test samples of dry beans, were subjected to soaking and cooking treatments to develop quick cookig methods and study their effects on quality of cooked products. The results of the study are summarized as follow: 1. Of the soaking methods tested, soaking soybeans in 3% sodium bicarbonate (SBC) solution and black-eyed peas in 0.5-1% SBC solution followed by cooking them in water at $95-100^{\circ}C$ required 40 minutes and 10 minutes of cooking time, respectively. When compared to 180 minutes of cooking time for soybeans and 40 minutes of that for black-eyed peas by conventional cooking method (Control), soaking dry beans in optimum SBC solutions reduced cooking time by over 80%. 2. Among cooking methods tested, steam cooking at $121^{\circ}C$ was the most effective one in reducing cooking time of soybeans (15 min.). Black-eyed peas sacked in water required 6 minutes of cooking time in 1% SBC solution at $95-100^{\circ}C$, and 5 minutes of that in steam at $121^{\circ}C$. 3. Quality of cooked beans with optimum texture was evaluated by sensory panel and Gardner Color Difference Meter. Beans cooked in steam at $121^{\circ}C$ had better overall quality than those cooked by other methods. Beans soaked in optimum SBC solution had quality as good as control, whereas beans cooked in SBC solution had worse quality than control. 4. These results indicated that cooking time of soybeans could be drastically reduced by either steam cooking at $121^{\circ}C$ or soaking in 3% SBC solution followed by cooking in water at $95-100^{\circ}C$. Cooking time of black-eyed peas could be significantly shortened by either steam cooking at $121^{\circ}C$ or soaking in 0.5-1% SBC solution followed by cooking in water at $95-100^{\circ}C$.

  • The effect heat treatment (autoclave) on nutritional value of winged bean as compared to soybean has been investigated. The winged bean and soybean were obtained from local cultivar grown in Indonesia. The beans were autoclaved at $120^{\circ}C$ for 15, 30, 45, 60 or 90 minutes, respectively before being ground for chemical analysis. Trypsin inhibitors of winged bean and soybean decreased (p < 0.05) along with decreasing of urease activity as heating time increased from 0 to 90 minutes. Heat treatment significantly (p < 0.05) reduced protein solubility in 0.2% potassium hydroxide of winged bean as well as soybean. In vitro protein digestibility was significantly (p < 0.05) improved by heating treatment (15 to 60 min of autoclaving), however, excessive heating (90 min of autoclaving) decreased the digestibility of winged beans. Excessive heating had adverse effect on lysine, cystine and methionine contents of winged beans. The results of this study suggested that autoclaving at $120^{\circ}C$ within 45 minutes should be adequate to remove protease inhibitors and could improve protein digestibility of winged beans.

  • Planting, transplanting, and harvesting are important processes for the successful production of farm products in Korea because those require the high labor intensity during limitted period. Recently, many researches of using automatic control with a microcomputer are carried in the agricultural field, but are not much spread to the seeder development. Automatic sowing technology would be much attractive if there was a way to assure that each seed was count accurately in the seed metering device. Thus, an automatic seed metering device was designed and constructed to be controlled by microcomputer. This device could be improved in not only counting the number of seeds in but also sowing seeds between row spacings. Automatic seed metering device consisted of conveyor belt and temporary storage device. Performance of seed metering device depends on the apparatus including sensor, stepping motor and DC-solenoid. Research contents and results are summarized as follows. 1. The seed metering device involving seed hopper, sorter and temporary storage device was designed and constructed. 2. A seed counting system with six photo electric sensors, designed and built for this project, was adequate for tranferring and counting seeds accurately. 3. Operating algorithm for stepping motor and photo electric DC-solenoid was developed. The Seed metering device proved to be a smooth and accurate operating device using the algorithm. 4. The performance of second prototype metering device was examined with five kinds of seeds ; mung beans, red beans, white beans, black beans and corn to transfer and count the seeds. The error ratio of seed metering was less than 3.5%.

  • Sixty four samples of cocoa beans replicated in quadruplicates were collected from five warehouses from southwest Nigeria and examined for fungal loads, ergosterol and eohratoxin A The levels of all the variables obtained were further used as indices for cocoa grading into food quality, FoQ (erg < 5 mg/kg; OTA < $1{\mu}g$/kg), feed quality, FeQ (erg = $5{\sim}10\;mg$/kg; OTA in the range of $1.1{\sim}3.11{\mu}g$/kg), Screen for mycotoxin, SFM (erg = $10{\sim}20\;mg$/kg; OTA from $3.12{\mu}g$/kg and above) with fuel quality, FuQ having erg > 20 mg/kg and OTA > $6.12{\mu}g$/kg. Using these ergosterol indices, 18.75% of the cocoa beans examined was classified with the FoQ, 18.75% with the FuQ while 31.25% was classified with both the FeQ and the SFM, respectively. In conclusion, ergosterol can be used as a rapid index to grade fermented, dried cocoa beans meant for export.

  • In the Internet based information technology community, the exchange of product information is more activated in e-commerce of B2C and B2B. We have suggested a XML based unified product description model with which all kinds of product informations can be represented. This model also has a feature to avoid duplication of the product information. In this paper, we will implement this model using Java Beans and EJB (Enterprise Java Beans) of the Java component technology, and then test this system over several products on the web. finally, we will analyze the effect due to the removal of the information duplication.

  • Coffee is one of the top selling products in the world. There are various coffee bean species around the world. Among them, Coffea Arabica is the most popular species. However, there are few studies on the metabolites of coffee beans so far. This study demonstrates effects of the planted regions on the metabolite concentrations of coffee beans. The metabolites of coffee beans can be affected by growing area even although same species are grown. Accordingly, we studied coffee bean metabolites extracted from the same species in different regions (The brand names, Kona from Hawaii, Mocha Matari from Yemen, and Blue Mountain from Jamaica) by using mixed solvent of methanol: water: chloroform. A comparative analysis by NMR spectroscopy was performed and the statistical techniques were used to figure out the differences. As a result, we found that chlorogenic acid, caffeine, citrate, and sucrose mainly contributed to the separation of the three groups. When compared with Kona and Blue Mountain, concentrations of chlorogenic acid, caffeine, and sucrose in Mocha Matari were observed to be relatively down-regulated. In addition, compared with the two other groups, concentration of citrate in Kona was observed to be up-regulated.
