  • The purpose of this study was to provide the basic information for bread with kinds of spice. The qualities of bread added with garlic, ginger, and cinnamon powder were investigated using sensory and mechanical evaluation. The result of sensory evaluation showed that the softness, color, brittleness, hardness, and chewiness of bread were increased as the amount of garlic, ginger and cinnamon powder increased. Lightness decreased by the addition of garlic, ginger and cinnamon powder, while redness and yellowness increased. Texture measurement showed that hardness, cohesiveness, springiness, gumminess and brittleness were the lowest in the breads with 1% garlic, ginger and cinnamon powder, and increased as the added amount of spice increased. A positive correlation was observed between the sensory and mechanical properties in general, while hardness and chewiness have negative correlation with sensory properties. Sensory properties of wheat flour odor, roasted taste, springiness and swelling were positively correlated with the acceptability. Breads with 1% garlic, ginger, and cinnamon powder showed a good overall preference.

  • In this study, white bread was prepared containing 1.5, 3.0, 4.5 or 6.0% barley leaves tea powder (BLTP). The samples along with a control were then compared regarding their quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, internal surface appearances and sensory qualities, all to determine the optimal ratio of BLTP. As the BLTP content increased, the pH of the dough and bread and the lightness decreased, whereas the total titratable acidity increased. The fermentation power of dough expansion increased with a longer incubation time. The control group was evidenced by a significantly higher specific volume and baking loss than that observed in the BLTP samples. However, greenness and yellowness evidenced the opposite effect. Hardness was highest at a substitution level of 1.5% and lowest at a level of 4.5%. Fracturability and resilience were not significantly different among the samples. For the internal surface appearance, darkness and greenness increased both increased at higher BLTP content. In the sensory evaluation, color, flavor and overall acceptability were highest in the control bread samples but minimal at a substitution level of 6.0%. Softness was the highest at the 3.0% substitution level and lowest in the control bread samples. Barley leaf flavor, astringency, bitterness and off-flavor increased as the BLTP content increased. Delicious taste was not significantly different among the samples. In conclusion, the results demonstrated that 4.5% BLTP may prove quite useful as a substitute for wheat flour in the production of white bread and may provide favorable nutritional and functional properties.

  • The objective of this study was to evaluate the quality characteristics of noodles made with a dried powder of the shoots and leaves from $Aralia$ $elata$and $Kalopanax$ $pictus$. Ash, protein, and dietary fiber contents of $A.$ $elata$ and $K.$ $pictus$ were higher than those of wheat flour. The protein and fat contents of $K.$ $pictus$ powder were higher than those of the $A.$ $elata$ powder, but ash and dietary fiber contents were less than those of $A.$ $elata$. When the amount of $A.$ $elata$ powder increased, brightness (L) values of dough decreased, and redness (a) and yellowness (b) values of dough increased. The weight and volume of the cooked noodles also increased, as did the turbidity of the soup. Addition of $A.$ $elata$ and $K.$ $pictus$ powders in noodles reduced the cutting forces needed to cut the cooked noodles. The sensory evaluation indicates that noodles with 5% $A.$ $elata$ and $K.$ $pictus$ powder added were the most preferable.

  • The effects of mushroom powder fer noodle pasty and noodle were investigated The peak viscosity of control was higher than that of added mushroom powder. The water absorption in farinograph slightly increased with the addition of mushroom powder. Decrease of lightness(L) and increase of redness(a) and yellowness(b) were shown with the increase of mushroom powder in wheat flour mushroom powder composite as well as noodles paste and wet noodles. The weight and volume of cooked noodles were decreased, but the turbidity of soup were not different with the addition of mushroom powder. The cohesiveness, springiness and chewiness of cooked noodles were increased with the addition of mushroom powder. The results of sensory evaluation cooked noodles showed that the wet noodles with high quality could be produced by 3∼5% addition of Pholiota adiposa powder.

  • Saururus chinensis powder was added into cookie dough at 5 levels (0%, 1.5%, 3%, 4.5%, and 6%) by partially replacing equivalent amount of wheat flour in cookie formulation, and cookies thus made were evaluated for physicochemical properties and sensory quality by a small semi-trained panel. Thickness and density of cookies increased significantly with increase in Saururus chinensis powder content (p<0.05); however, those of dough were not affected (p<0.05). The pH of both dough and cookies decreased significantly as the level of Saururus chinensis powder increased (p<0.05). Lightness and yellowness decreased significantly as the Saururus chinensis powder content increased while redness increased significantly (p<0.05). Spread factor decreased with the powder addition (p<0.05). Sensory evaluation indicated that samples with higher amount of the powder received higher scores in terms of taste, flavor, and color but not for hardness (p<0.05). Finally, correlation analysis showed that level of Saururus chinensis powder incorporation was well-correlated with most of the physicochemical properties and sensory attributes studied.

  • This purpose of this study was to develop a functional muffin by adding yam powder in the shape of a muffin as a partial surrogate for wheat flour. The yam has been found to be effective for liver and kidney function, as well as the digestion of protein, since it produces glucuronic acid in the body. Therefore, the purpose of this study was to determine the optimal mixing conditions of yam muffins by adjusting the amounts yam powder, butter, and sugar. The mixing conditions for the yam muffins included 3 categories: yam powder $(X_1)$, sugar $(X_2)$, and butter $(X_3)$ by Central Composite Design (CCD) which was optimized by Response Surface Methodology (RSM). The effects of the three variable additions on muffin quality were examined via physical and chemical experiments, such as the analysis of texture (hardness, cohesiveness, springiness, gumminess), coloration (lightness, redness, yellowness), and height. Lastly, we performed a sensory test, which revealed significant findings for gumminess, color, appearance, flavor, softness (p<0.05), redness, and overall quality (p<0.01). Consequently, the optimal mixing rate which best satisfied the sensory items were 34.35g of yam powder, 80.15 g of sugar, and 80.55 g of butter.

  • This study investigated the quality characteristics and retarding retrogradation of sponge cakes made with red yeast rice (RYR) flour. RYR (Monascus nuruk) is known to help digestion, smooth blood flow, and have anti-cancer, anti-microbial, and inhibitory effects against biosynthesis of cholesterol and blood pressure. This studys aim' was to find the optimal proportion of RYR flour in sponge cake. RYR sponge cakes were prepared with various levels (0, 5, 10, 15 and 20%) replacement of wheat flour and were designated as the control (without RYR), RYR5, RYR10, RYR15 and RYR20 respectively. Specific gravity was the lowest in RYR15 at 0.57, and the baking loss rate was not significantly different among the samples (p<0.05). The dough yield was the highest in RYR15 at 96.61. The moisture contents was highest in order, control, RYR5, and RYR15 at 28.67%, 28.18%, and 26.82% respectively. The L-value of crust tended to increase according to the level of RYR, but the L-value of crumb decreased in accorddance with the the content of RYR. The a-value of crust also decreased according to the level of RYR, although the a-value of crumb increased in response to higher levels of RYR. The b-value tended to decrease with increases of RYR (p<0.05). RYR5 exhibited the highest pH at 8.63, compared with RYR15 (8.57). The hardness, which was measured after cooling for 1 hour, was the lowest in RYR15 at $163.33g/cm^2$ and the springiness was not different significantly (p<0.05). Cohesiveness was the highest in RYR10 at 133.06%. The chewiness was the highest in RYR10 at $391.63g{\cdot}cm$ and lowest in RYR15 ast $169.62g{\cdot}cm$. Avrami equation showed that RYR15 and RYR20 had the lowest Avrami exponent (n) at 0.0664 and 0.4983 respectively. Time constant (1/k) was the highest in RYR15 at 200.00. Sensory evaluation revealed that RYR15 was the highest in color (5.50), flavor (4.95), sweetness (4.90), chewiness (4.75), and overall acceptability (4.60).

  • Durum wheat semolina was added into wet-milled rice flour in order to improve chewy texture, firm bite ("al dente"), and resistance to overcooking of the ordinary rice noodles. Wet noodles were prepared by mixing 0 (control), 5, 10, 15, and 20% (w/w) of semolina per semolina and rice flour mixtures. Vital gluten (4%, w/w) and salt (2%, w/w) were added to form the pliable strands of wet noodles and final moisture contents of the raw mixtures were equalized at 45%. Pasting properties of the suspended flour mixtures as measured by the Rapid Visco Analyser (RVA) showed slight increases (up to $1.2^{\circ}C)$ in pasting temperatures along with the considerable decreases in peak viscosities as semolina increased at over 15%. Reduced shear thinning and retrogradation of the starch solution that leads to hardening of the cooked noodles were indicated by lowered breakdown viscosities and gaps between finaland setback viscosities from the RVA viscogram as semolina increased at over 10%. Reduced water uptake and turbidity increases of the cooking water as caused by the soluble starches from the noodle were also noted as the content of semolina increased. More or less significant (p<0.05) decreases in colorimetric L (lightness) value of the raw- and cooked noodles were observed as semolina increased while a- (redness) and b (yellowness) values were rather increased at the same moment. Textural properties of the cooked noodles such as hardness, springiness, cohesiveness, gumminess, and chewiness from TPA tests were significantly (p<0.05) influenced by added semolina, even at 5%-levels or more. It can be concluded that addition of semolina into rice flour could provide easy handling of the wet noodles without distortion during transportation, integrity and firm bite of the cooked noodles, and less loss of starch to the cooking water in comparison with the ordinary rice noodle. It was finally suggested that optimum level of the semolina in the product was approximately 10% for the quality wet rice noodle products.

  • Wet noodles with different percentages of amaranth powder were prepared and their cooking characteristics were evaluated. The cooking quality, mechanical textural properties, and a sensory evaluation was conducted with the prepared noodles. Cooked noodle properties, weight, and volume decreased as amaranth content of the wheat flour increased, whereas turbidity and water absorption of the soup increased, except for cooked noodles with 30% amaranth. The L-value of the raw and cooked noodles decreased significantly with increasing amaranth powder content. The a- and b-values increased with increasing amounts of added amaranth powder. The L-value of the raw and cooked noodles with amaranth was significantly lower than that of the control, and the a-value was lower than that of the control, whereas the b-value was higher than that of the control for both raw and cooked noodles. A texture profile analysis of the raw noodles showed significantly higher levels of hardness, cohesiveness, gumminess, chewiness, and springiness in the amaranth noodles compared to those in the control; the values for adhesiveness were not significantly different. The hardness, gumminess, springiness, and chewiness of the cooked noodles decreased in proportion to the quantity of added amaranth. The springiness, adhesiveness, and cohesiveness of cooked noodles with amaranth decreased slightly. Overall, the results of a sensory evaluation revealed that the cooked noodles with amaranth had higher values than those of the control, except for overall acceptability. Amaranth added at a concentration of up to 30% increased brown color and the peculiar amaranth odor. In a sensory evaluation, cooked noodles with 20% amaranth powder were preferred more than the other noodles for overall acceptability.

  • The study was carried out to investigate the quality of the wet noodle added with the powders of nopal and nopalitos from Opuntia ficus-indica. The wet noodles were prepared to the ratio of 3, 6 and 9% (w/w) of the nopal and the nopalitos based on a flour weight. The initial pasting temperature and final viscosity in an amylograph decreased as the increase of the nopal and the nopalitos powders. A cooked weight and volume decreased with the increase of the nopal and the nopalitos powders, while a cooking loss increased. From the sensory evaluation, the wet noodles included 3% nopalitos and 6% nopal powders were similarly evaluated as the noodle used whole wheat flour. Bacterial counts of wet noodle with the nopal and the nopalitos powders were always lower than those of the control. Bacterial counts of wet noodle slowly increased as the increase of the amount of nopal and the nopalitos powders during storage at $4^{\circ}C\;and\;20^{\circ}C$. The methanol extracts from the nopal showed antimicrobial activities against Escherichia coli, Escherichia coli O157 : H7, Salmonella typhimurium, and Bacillus subtilis, while the extracts from the nopalitos showed antimicrobial activity only against Escherichia coli.
