  • The quality characteristics of bread added with the levels of $0\%,\;1.0\%,\;2.0\%\;3.0\%\;and\;4.0\%$ prickly pear powder were investigated. Mixing water absorption capacity was increased by increasing amounts of prickly pear powder. Mixing time of dough was increased compared to that of wheat flour by added prickly pear powder, while it decreased as prickly pear powder content increased. Dough stability of wheat flour added with $1.0\%$ prickly pear powder was similar to wheat flour dough, while decreased by increasing amount of prickly pear powder at the range of $2.0\~4.0\%$. Pasting temperature($66.1\~66.9^{\circ}C$) of wheat flour added with $1.0\%,\;2.0\%\;3.0\%\;and\;4.0\%$ prickly pear powder was lower($67.8^{\circ}C$) than that of wheat flour. Peak viscosity($2,226\~2,375$ cp) of wheat flour added with $1.0\%,\;2.0\%\;3.0\%\;and\;4.0\%$ prickly pear powder were higher(2,288 cp) than control, and increased with increasing amount of prickly pear powder Setback($797\~750$ cp) of wheat flour added with $1.0\%,\;2.0\%\;3.0\%\;and\;4.0\%$ prickly pear powder were lower(803 cp) than that of wheat flour, and decreased with increasing amount of prickly pear powder. The volume of dough added with prickly pear powder decreased compared to that of the wheat dough. The specific loaf volume of bread added with prickly pear powder decreased($8.0\~18.5\%$) compared to that of the wheat bread. Color of crumb was deep red gradually with the increasing amount of substituted prickly pear powder. Hardness, adhesiveness, gumminess and chewiness of bread were increased gradually with the increasing amount of substituted prickly pear powder but the springiness was decreased. The sensory evaluation showed that bread of wheat flour added with $2.0\%$ prickly pew powder was superiority than the wheat flour bread.

  • Baking properties of Korean domestic wheat flour supplemented with pine pollen powder were investigated. Farinographic characteristics showed that the addition of pine pollen increased water absorption without any changes in dough development time and stability of dough in comparison with control. A higher gelatinization temperature and a lower maximum viscosity of dough on amylogram were observed with pine pollen powder addition. The addition of pine pollen powder showed decrease in redness and increases in lightness and yellowness of bread crumb. A significant increase in bread volume was observed as the pine pollen powder added more. Springiness. cohesiveness and resilience of bread were increased by pine pollen powder. Sensory evaluation of bread showed that the addition of pine pollen powder, especially at the level of 1%, enhanced color, mouth feeling, bleak and appearance without significant reduction of overall acceptability.

  • To improve the mechanical properties of Hanji, starches such as maize, konyaku, and wheat powders were added at various concentrations in the manufacturing processes of Hanji. The effect of starches on the physical properties of Hanji was as follows. Filling rates of surface of hanji were increased with the increase of the concentration of starch. Hanji surface were completely filled at the 3.0% konyaku treatment. Konyaku powder showed higher filling rates than maize and wheat powder. The breaking length was increased with the increase of filling rates. Konyaku powder showed the highest breaking length: Tear index of hanji treated with maize and wheat powder were a little improved but that of hanji treated with konyaku powder were a little decreased compared to non-treated hanji. In conclusion, starch treatment showed the increase of the breaking length, but no effect on tear index.

  • The purpose of this study was to evaluate the physicochemical components and antioxidant activities of wheat sprout powder prepared by the enzymatic hydrolysis and lactic acid bacteria treatment. The four kinds of pre-treatment were: no treatment (WP), treated with enzyme (WPE), treated with lactic acid bacteria (WPL), and treated with enzyme and lactic acid bacteria (WPEL) were applied to the wheat sprout powder. The WPEL had higher total free amino acid and essential amino acid content than the other samples. As for the volatile aroma of the wheat sprout powder, 29 types of compounds were identified in the WP and WPL, 28 types in the WPE, and 27 types in the WPEL, respectively. The total polyphenols and flavonoids contents, in the wheat sprout powder was enhanced with the enzyme and the lactic acid bacteria pre-treatment. The WPEL had highest DPPH radical scavenging activities. The overall acceptability was the highest at 6.24 points in the WPEL. Based on these observations, it was confirmed that the enzyme and lactic acid bacteria pre-treatment could improve the antioxidant activities and active component of the wheat sprout powder.

  • The purpose of this study was to evaluate the quality characteristics of white pan bread added with wheat sprout powder without treatment (WP) and wheat sprout powder with only enzyme treatment (WPE), only lactic acid bacteria treatment (WPL) and enzyme and lactic acid bacteria treatment (WPE&L). The three different powder concentration levels of 1%, 3%, and 5% were added to flour to produce the white pan bread. The bread volume and specific volume of the WPE&L group were the highest among all the addition groups. The bread weight, a-value, and b-value of the WP group was highest among all the addition groups, but the bread baking loss and the L-value of the WP group was the lowest among all the addition groups. The texture measurements indicated that the hardness, gumminess, and chewiness values of the bread were the highest in the WP group. The sensory evaluation test showed that bread in the WPE&L group with 3% wheat sprout powder was the best among all the samples studied. Based on our findings, we suggest that the enzyme and lactic acid bacteria pretreated wheat sprout powder is an effective ingredient for improving the overall quality of white pan bread.

  • Wet noodles were prepared with wheat flour and mushroom powder (oyster and oak mushrooms), and effects of added mushroom powders on dough rheology and wet noodle quality were examined. Particle size distribution of mushroom powder ranged from 0.04 to $500\;{\mu}m$, which was different from that of wheat flour. The initial pasting temperature in amylograph, and the water absorption and the dough development time in farinograph increased with the increase of mushroom powder. The peak and final viscosities in amylograph, and dough stability in farinograph decreased with the increase of mushroom powder. Decrease of L value and increase of a and b values were shown with the increase of mushroom powder in wheat flour-mushroom powder composite as well as wet noodles. The cooked weight and volume of cooked noodles were decreased, but the turbidity of soup were increased with the addition of mushroom powder. Most of texture parameters (hardness, cohesiveness, chewiness and cutting force) of cooked noodles decreased with the addition of oyster mushroom powder, but increased with the addition of oak mushroom powder. From the result of sensory evaluation, wet noodles containing 3% oyster mushroom powder and 5% oak mushroom powder were rated as high quality wet noodles.

  • The antiobesity effect of commercial kochujang and fermented wheat grains in Sprague-Dawley (SD) rats was studied. The experiment was consisted of 6 groups. Normal, high fat diet (HFD), HFD+raw wheat grains, HFD+first fermented wheat grains (FFWG, with Aspergillus oryzae) HFD+final fermented wheat grains (FiFWG, fermented more for 30~40 days), and HFD+ commercial kochujang. The results showed that final body weight, weight gain, food efficiency ratio, and adipose tissue weight were markedly decreased by the commercial kochujang and the fermented wheat grains, whereas non-fermented raw wheat grains had no such effect. Lipid contents such as total lipid, total triglyceride and total cholesterol decreased in the serum and organs of liver and adipose tissues by the commercial kochujang and the fermented wheat grains as well. These results also indicated that fermented wheat grains exhibited more suppressive effects on high fat induced-obesity than raw wheat grains. Increased fermentation time and adding the red pepper powder resulted in increased the anti-obesity effect. Especially, commercial kochujang showed higher antiobestic effects than fermented wheat grains. These in vivo findings suggested that well-fermented end products of the wheat grains and red pepper powder in kochujang could be useful in the prevention of obesity.

  • To reuse the waste bone from restaurants or butcher houses, the possibility of using waste bone powder after cooking as a filler for wood adhesives used in manufacturing plywood was investigated. Radiata pine (Pinus radiata D. Don) plywoods were manufactured by using commonly used wood adhesives such as urea-melamine formaldehyde (UMF) resin, urea-formaldehyde (UF) resin, and phenol-formaldehyde (PF) resin and the prepared fillers from cattle bone powder, pig bone powder, and seashell powder. Plywood fabricated by using cattle bone powder, pig bone powder, and seashell powder showed weaker performance in dry and wet glue-joint shear strength and wood failure than those of the plywood with wheat flour. The result showed that it was hard to use only bone powder for the replacement of wheat flour. However, the filler mixed with wheat flour and bone powders showed equivalent dry bonding strength and better water resistance than the wheat flour, indicating that bone powders mixed with wheat flour might be used for the manufacture of plywood. When bone powders were mixed with wheat flour as adhesive fillers the shell powder showed the lowest bonding properties and there was no big difference between the cattle bone powder and the pig bone powder.

  • The growth inhibitory effect of wheat grain, fermented wheat grain products, red pepper powder and kochujang was examined in AGS human gastric adenocarcinoma cells. The kochujang samples were prepared by mixing red pepper powder and each fermented wheat grain products, such as first fermented wheat grain (FFWG), second fermented wheat grain (SFWG) and final fermented wheat grain (FiFWG). The methanol extract of FiFWG showed the highest growth inhibitory effects. In order to investigate the effects of fermented wheat grain products at each stage of fermentation on anticancer activity, the kochujang prepared with red pepper powder and each of FFWG, SFWG and FiFWG were fermented until reaching pH 5.1. The kochujang adjusted to pH 5.1 by fermentation increased the growth inhibitory effect; however, the kochujang prepared with FiFWG showed the highest effect. Increased fermentation time increased the growth inhibitory effect of kochujang when prepared with FiFWG. These results suggested that the anticancer effect of the kochujang on the gastric cancer cells was affected by the fermentation periods of the wheat grains. The well-fermented end products of the wheat grains seem to be one of the major components that showed anticancer activity of kochujang.
