  • This research intends to research on the optimal cooking techniques by adding perilla leaves to raw noodles, in which it has various effects and functions in sterilization. The water content measured in the dough added with raw perilla leaf juice came out high as more perilla leaves were added. More freeze-dried perilla leaf powder decreased water content. The pH of the dough increased significantly as the added ingredients increased with significant differences among the samples. The chromaticity of the dough deliberately decreased in both a and b as the amount of raw perilla leaves in dough increased. The L value of raw noodles with freeze-dried perilla leaves tended to decrease as more ingredients were added. The result of the RVA analysis on the dough with raw perilla leaves showed that the gluten decreased with more raw perilla leaves added. The result of the RVA analysis on the dough with freeze-dried perilla leaf powder indicated that the initial pasting tempo tended to increase significantly with more powder added except for 5% and 7% of powder added with no significant difference. The values dropped as the freeze-dried powder was added Minimum viscosity tended to decrease definitely as more freeze-dried perilla leaf powder was added. The dough's measurement results of WRC showed that water absorbing power of both dough with raw perilla leaves and that with freeze-dried perilla leaf powder reduced significantly as more perilla leaf powder were added.

  • The effects of Poria cores powder addition on bread making were investigated by evaluation of dough rasing power, rheological properties of dough by farinograph and extensograph color and sensory quality. As increment of Poria cocos powder, dough rasing power and extensibility were decreased but water absorption rate and resistance were increased. Time for dough formation, stability and v/v point of dough were increased when 5 and 10 percent of Poria cocos powder were added. Color of bread wasn't significantly different when Poria cocos powder was added up to 10 percent. Overall acceptance by sensory evaluation was the best when 5 percent of Poria cocos powder was added, tut there are no significant difference among breads which were made with various mixing rates of Poria cocos powder.

  • This study was carried out to investigate the rheological properties of bread dough containing whey ferment cultured by L. acidophilus KCCM 32820 and P. freudenreichii KCCM 31227. Instrumental analysis such as farinograph, amylograph, extensograph, fermentation power, total titratable acidity (TTA) of dough and pH of dough were tested. On farinograph, difference of water absorption between doughs with and without whey ferment was 0.4% and dough containing whey ferment showed long development time of 3.2 min compared to dough without whey ferment, but showed shorter stability of 16.2 min. On amylograph, there was no significant difference on gelatinization and maximum viscosity temperature; however, maximum viscosity of flour with whey ferment revealed low amylograph unit. On extensograph, value of resistance and R/E ratio of dough containing whey ferment were higher than those of dough without whey ferment. On analysis of dough fermentation power by yeast, dough without whey ferment showed higher volume than dough with whey ferment during fermentation of 240 min. However, TTA of dough was higher in dough with whey ferment than that of the control without whey ferment, even though pH value was low.

  • Practical use of wheat flour ferment with L. acidophilus during noodlemanufacturing was investigated. Water absorption decreased and overall mechanical tolerance index increased with ferment addition up to 20%. Amylograph of flour with ferment showed initial gelatinization temperatures of control, and 5% ferment-and ferment-added groups were equal. Maximum viscosity decreased by ferment addition. L, b and a values of dough increased proportionally with added ferment. Color of doughs with ferment was generally ligher. Total color difference of doughs added with ferment was higher than that of control group.

  • The effects of adding additives such as gum, emulsifier, and enzyme both individually and as mixtures to frozen rice bread dough on baking quality were examined. Rice flours containing 17% vital gluten, and gum/emulsifier/enzyme blends were mixed and stored in a freezer at $-20^{\circ}C$ for 4 weeks. The rice doughs were removed from the freezer, thawed, and then followed the rice baking procedure. The dough freezing and frozen storage resulted in decreased volume of rice bread. The addition of guar gum/sodium stearoyl lactylate (SSL)/fungal $\alpha$-amylase blend improved volume of the rice bread obtained from rice dough during frozen storage. An increase in firmness of crumb was observed in rice breads during 3 days of storage at $25^{\circ}C$. Compared to the control dough without additives, addition of guar gum/ SSL blend or guar gum/ SSL/ fungal $\alpha$-amylase blend into frozen dough significantly reduced the crumb firmness of rice bread, indicating a significant antistaling effect.

  • This study investigated the rheological properties of bread dough supplemented with lotus (Nelumbo nucifera) seed powder. The rheological properties measured were dough volume, farinogram, amylogram, extensogram, pH and outernal. The lotus seed powder contained 7.74% moisture, 20.15% crude protein, 2.11% crude fat, 4.34% crude ash, and 2.78% crude fiber. The farinogram showed that with increasing concentration of lotus seed powder the absorption rate of the dough increased slightly, the development time and stability decreased, and the degree of attenuation tended to be grown along. From the amylogram it was found that the gelatinization onset temperature and the maximum viscosity of the dough tended to increase with increasing content of lotus seed powder. The extensogram showed that the degree of extension of the dough decreased with increasing content of lotus seed powder, while the degree of resistance and resistance/extensibility increased. The dough pH tended to decrease with fermentation time, but increased with increasing content of lotus seed powder. A concentration of $5{\sim}10%$ lotus seed powder appears to be suitable for the preparation of dough.

  • Scanning electron microscopy was used to study changes in granule shape, dough and cooked noodle structure of pea starch-wheat composite flour with 20% and 30% pea starch substitution. The granule shape of pea starch with low swelling power and solubility was oval, irregular and smooth, which had more a deep groove than corn starch and wheat flour. During gelatinization, pea starch after swelling was partially collapsed but it still held its main shape. The dough microstructure of 20% pea starch substitution showed compact structure distributed with more small starch granules than wheat dough and was held in discontinuous network. When cooked, more open filamentous network where starch gelatinization was complete were noticed. Swollen but partially collapsed large starch granules maintaining their shape were appeared in noodle structure after 30 min soaking in soup. In farinograph studies, 20% pea starch substitution to wheat flour showed that MTI value was as same as wheat flour even though stability was slightly decreased so that it was considered that it has proper property of noodle making.
