  • 카라기난, 트랜스글루타미제, 분리대두단백, 밀 식이섬유 첨가 종류에 따른 돈육 패티의 이화학적 및 관능적 특성을 조사하여, 결착제 첨가 종류에 따른 식육제품의 품질 변화를 알아보고자 하였다. 결착제 첨가 종류에 따른 보수력, 가열수율 및 수분함량은 대조구와 비교하여 카라기난, 분리대두단백 및 밀 식이섬유 첨가구가 높은 수치를 나타내었고, 직경감소율 및 두께감소율도 대조구와 비교하여 카라기난, 분리대두단백 및 밀 식이섬유 첨가구가 낮은 수치를 나타내었다. 전단력은 카라기난 첨가한 처리구가 가장 낮은 수치를 나타내었다. 또한 관능적 특성에서 연도, 다즙성 및 전체적인 기호도에서 대조구보다 결착제를 첨가한 처리구들이 높은 점수를 받았으나, 대조구를 포함한 모든 처리구에서 유의성이 인정되지는 않았다. 그러므로 결착제 첨가 종류에 따른 이화학적 및 관능적 특성 비교를 통하여 소비자 기호에 적합한 패티를 제조할 수 있는 기초자료로 활용할 수 있을 것으로 사료되며, 이러한 기초자료들을 바탕으로 다양한 첨가제들을 활용하여 다양성이 있는 식육제품 개발에 필요한 기초자료로 활용될 수 있을 것으로 보여진다.

  • Fully biodegradable and environment-friendly green composite specimens were made using ramie fibers and soy protein concentrate (SPC) resin. SPC was used as continuous phase resin in green composites. The SPC resin was plasticized with glycerin. Precuring and curing processes for the resin were optimized to obtain required mechanical properties. Unidirectional green composites were prepared by combining 65% (on weight basis) ramie fibers and SPC resin. The tensile strength and Young's modulus of these composites were significantly higher compared to those of pure SPC resin. Tensile and flexural properties of the composite in the longitudinal direction were moderate and found to be significantly higher than those of three common wood varieties. In the transverse direction, however, their properties were comparable with those of wood specimens. Scanning electron microscope (SEM) micrographs of the tensile fracture surfaces of the green composite indicated good interfacial bonding between ramie fibers and SPC resin. Theoretical values for tensile strength and Young's modulus, calculated using simple rule of mixture were higher than the experimentally obtained values. The main reasons for this discrepancy are loss of fiber alignment, voids and fiber compression due to resin shrinking during curing.

  • The purpose of this research was to study the effects of initial moisture levels and extrusion temperatures on dietary fiber, nitrogen solubility index, available lysine, and the in vitro protein digestibility of extruded oat productes. The dehulled grains were ground in a Brabender quadrumat Senior mill and the coarse fraction, with higher crude protein, lipids and dietary fiber were conditioned on various mositre levels (15.5~25.5%) and extruded in a Brabender single-screw laboratory extruder. The extrudates showed a higher amount of soluble dietary fiber (8.14%) than in the raw material . However, the extrusion process affected the nutritional value of the protein due to a decrease in available lysine with increased temperature . The in vitro protein digestibility was unaffected by initial moisture levels and the extrusion temperatures examined.

  • The dyeing properties of protein fiber with pine needles colorants were studied through an investigation of the effect of dyeing conditions such as dye concentration, dyeing temperatures and time on dye uptakes, effect of mordants, and color change. In addition, the various colorfastness of dyed silk and wool fabrics were evaluated for practical use. The antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. The dye uptake increased as the dyeing concentration increased and this enabled the obtainment of the Langmuir absorption isotherm. The dye uptake increased as the dyeing time and temperature increased. Pine needles colorants showed relatively good affinity to protein fiber and produced a yellow color. Post-mordanting was more effective than the pre-mordanting, and the dye uptake of fabrics improved by mordanting. Except for washing, the colorfastness of dyed fabrics showed a low rating. However, the colorfastness to light and the dry cleaning of fabrics mordanted with N.Cu, and the friction fastness of fabrics mordanted with Cu improved. The guide fabrics showed very good antimicrobial abilities of 99.9%; in addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

  • This experiment was carried out to compare chemical composition of corn-cowpea inter cropping and corn monocropping plants at different harvestion time and obtained the following results. 1. In both cropping systems, the contents of crude fat and nitrogen free extract (NFE) were significantly increased (P<0.01), while that of crude protein crude fiber and crude ash were decreased (P<0.01) with each harvesting time. 2. The acid detergent fiber (ADF) and crude fiber contents were decreased same patterns in growing period, however, according to maturing of corn ears the difference between ADF and crude fiber contents reduced. 3. At mature stage, crude protein yields per 10a in corn monocropping and corn-cowpea intercropping system were 127.6kg and 152.1kg, respectively. The difference of crude protein content between corn-cowpea intercropping and corn monocropping system was 19.2%. 4. TDN yields of each cropping system, at mature stage, obtained similar results and TDN yields per 10a of corn monocropping and corn-cowpea intercropping system were 1006.1kg and 990.1, respectively. 5. Conseqently, corn-cowpea intercropping system could be increased protein yield without decreasing of dry matter yield in comparison with corn monocropping system.

  • Dyeing properties of protein fiber with bamboo colorants were studied by investigating the effect of dyeing conditions such as dye concentration, dyeing temperatures, times on dye uptakes, effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use. In addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were estimated. The dye uptake increased as the dyeing concentration increased. Bamboo colorants showed relatively good affinity to protein fiber and produced a yellow color. Dye uptake increased as the dyeing time and temperature increased. Post-mordanting was more effective than pre-mordanting. Mordants, Fe and N.Fe, were effective for increasing dye uptake. The color of fabric mordanted with Cu and N.Cu changed to GY. Colorfastness of dyed fabrics showed a relatively good rating, and mordanting had no significant effect on colorfastness. Dyed silk fabric showed very good antimicrobial abilities of 99.9%. Also, ultraviolet-cut ability and deodorant ability were improved in silk fabric dyed with bamboo extracts.

  • This study was performed to investigate nutritional effect of various dietary fibers on lead absorption, and protein and lipid metabolisms in growing rats. Sixty male rats of Sprague-Dawley strain weighing 140$\pm$1.1g were blocked into 10 groups according to body weight and fed 10 kinds of diet different with fiber sources [non-fiber, cellulose, pectin, guar gum or carboxymethylcellulose(CMC)] and lead levels (0 or 1%) for 4 weeks. Results were summerized as follows : 1) Food intake, weight gain, FER and PER were remarkably decreased in lead(Pb)-added groups. Weight gain, FER and PER in Pb-added pectin group were significantly lower than those in Pb-added non-fiber group. 2) Liver and kidney weights, femur weight and length, hematocrit and hemoglobin content were decreased in Pb-added groups. Especially femur and liver weights in pectin groups were the lowest among groups. 3) Total protein content in serum was significantly decreased in Pb-added groups but was not different with dietary fiber sources. Total lipid content in serum was not different with dietary Pb levels and fiber sources, but cholesterol content in serum of guar gum group was significantly decreased by Pb addition. 4) Nitrogen, lipid and cholesteol contents in liver were significantly decreased in Pb-added groups, and lipid content in liver of pectin and CMC groups was lower than other groups. 5) Daily urinary and fecal excretions of nitrogen, kipid and cholesterol were decreased in Pb-added groups, and fecal nitrogen was significantly increased in Pb-added groups, and fecal nitrogen of cellulose and guar gum groups was significantly higher than other groups. Fecal excretions of lipid and cholesterol were increased by dietary fibers, and especially fecal lipid was remarkably increased in pectin and guar hum group. 6) Pb contents in liver and femur were decreased by dietary fibers. Especially Pb contents in liver, kidney and femur were significantly decreased in guar gum group. 7) Daily urinary and fecal excretions of Pb were significantly increased in cellulose and guar gum groups, and fecla excretion of Pb in guar gum group was twice of non-fiber group. Pb absorption ratio was significantly decreased in guar gum group. In conclusion, dietary fibers have effect on protein and lipid metabolisms, and decreased intestinal absorption of Pb by increasing fecal excretion. But the degree of effect was different with dietary fiber sources.
