  • Physicochemical and sensory characteristics of rice cookies prepared with various levels of amylose content were investigated in this study. Dough pH of Jinsumi and Milyang 261 cookies was decreased by addition of rice flour. Density of dough with 100% substituted Jinsumi flour had the largest value of 1.09 g/mL, whereas that of Milyang 261 cookies showed no significant difference. Spread ratio of cookies was the largest in the cookies containing Jinsumi, and Milyang 261 constituted the 50% group. Preservation ability of Milyang 261 cookies surpassed above 30%. Lightness of Jinsumi and Milyang 261 cookies increased with increasing rice flour content. The results of our sensory evaluation demonstrated that the control sample was significantly more preferable in terms of overall acceptability compared to others. These results suggest that adding 30% Milyang 261 flour is the best substitution ratio for rice cookies.

  • This study examined the effects of adding Pleurotus ostreatus, Agaricus bisporus and Flammulina velutipes on the quality characteristics of cookies and multiple purposes of wheat powders. The water content, crude protein content, mineral content, color value and sensory evaluation of mushroom cookies and multiple purposes of wheat powders were measured. In the case of cookies, the water content was 1.10-1.24% and crude protein content was 8.20-9.80%. General preferences, such as appearance, color, taste and texture, increased when mushroom was added to the cookies, especially flavor, which showed a much higher preference. In the studies where mushroom was added to wheat powders, the water content was 0.57-0.92% and crude protein content was 11.90-12.80%. The addition of mushroom to both of the cookies and multiple purposes of wheat powders resulted in a remarkable increase in the mineral content, especially Fe, K. In addition, an increase in the amount of added mushrooms resulted in an increase in the hunter L and a values; however, this also resulted in a decrease in the b value.

  • Chlorella is an attractive potential food source because it is high in protein and other essential nutrients; when dried, it is about 45% protein, 20% fat, 20% carbohydrate, 5% fibre, and 10% minerals and vitamins. It has been widely used as a well-being food. We investigated the quality characteristics of cookies prepared after addition of various concentrations of chlorella powder (0%, 1%, 3%, and 5%, all w/w) as a substitute for flour. In this study, as chlorella powder concentration rose, decreases in the moisture content, pH, L, a and b value became evident. The spread factor and hardness of the cookies slightly increased after the addition of chlorella powder. Sensory evaluation scores in terms of color, flavor, and texture were statistically very similar, but taste and overall acceptability scores were lower than those of the control. The result of this study showed that the quality of the cookies with the addition of 1% chlorella powder was the best in terms of its taste, flavor, texture, and sensory properties.

  • The objective of this investigation was to develop iced cookies with freeze-dried yellow onion powder (YP) and red onion powder (RP) at composition levels of 0, 1, 3, 5 and 10%. The moisture (13.61%) and crude ash contents (3.43%) of YP was higher than RP, while the crude protein (7.58%) and crude fat contents (0.65%) of RP was higher than YP. Freeze-dried YP showed a higher lightness and yellowness value compared to RP, because of the unique color of the onion. The browning index was lower in YP. The pH of the dough significantly decreased by addition of onion powder, while the density of the dough was significantly increased in RP samples than the others. The iced cookies showed a lower lightness value, and a higher redness value with increase of onion powder contents. Hardness of YP cookies up to 5% and RP cookies up to 3%, were lower compared to the control. With regards to the sensory characteristics, $3{\sim}5%$ YP cookies and 3% RP cookies were more acceptable than the others. As a result, the optimal ratio of freeze-dried YP and RP iced cookies were calculated at 5% YP and 3% RP levels.

  • This study was conducted to investigate the effects of adding gochujang addition to cookie dough on the quality characteristics of cookies. Cookies were prepared by replacing 0% 5%, 10%, 15% and 20% flour with gochujang. The gochujang pH, total soluble solid and salinity were $4.84{\pm}0.02$, $63.33{\pm}4.19%$ and $7.63{\pm}009%$, respectively. The moisture content in gochujang was $40.10{\pm}0.10%$, and the color values of gochujang was were as L-value $24.46{\pm}0.06$, a-value $10.18{\pm}0.13$, and b-value $7.44{\pm}0.10$. The pH values of cookies decreased according to the addition of gochujang. The values of density and loss rate in cookies were not-significantly different among the samples. Spread factor and moisture content of cookies increased with amounts of added gochujang. The salinity and total soluble solid content of cookies with gochujang were significantly higher than those of the control. L-value was significantly reduced, and a-value and b-value increased by adding gochujang. Total phenolic content and DPPH free radical scavenging activities were increased according to the amount of gochujang. For sensory evaluation, gochujang added cookies were more preferred in terms of color, softness and overall preference. Overall, these results indicate that adding 10% gochujang is desirable for making gochujang cookies.

  • The quality characteristics of cookies between fresh shredded garlic(FSG) and heat-treated($150^{\circ}C$, 5 min) shredded garlic (HT-SG) were comparatively analyzed based on different content additions. The levels investigated were 0, 0.5, 1, 2, 4 and 6% for both shredded garlics. Dough pH was lower in the FSG-added cookies than in the HT-SG-added cookies. The spread factor decreased with the addition of shredded garlic compared to the control($10.63{\pm}0.57$), but differences were insignificant within each group. Cookies hardness was highest at 2% garlic content, and it was higher for HT-SG than FSG. Compared to the measured L-value of the control, the L-values of the test samples decreased with increasing garlic contents. With increasing garlic contents, the a-value increased, but the b-value remained mostly unchanged, with less significant difference compared to the control. The color of the HT-SG group tended to be brown as the garlic content increased. The degree of browning was more pronounced for HT-SG than FSG. Surface cracking of the cookies tended to be higher in the FSG samples than in HT-SG. Compared to the control, garlic taste and flavor increased remarkably with increasing garlic content, and they were stronger for the FSG cookies. The overall acceptability of HT-SG was relatively high, and it was highest for the HT-SG cookies with a 0.5~2% garlic contents than for the control cookies.

  • This study was conducted to develop an optimal composite recipe for nutritional cookies containing beet powder. Flour was substituted with whole wheat flour containing germinated brown rice powder. The sensory optimal composite recipe was determined by making cookies containing two levels of beet powder (A) or butter (B) according to Central Composite Design (CCD) and by conducting the sensory evaluation and instrumental analysis according to Response Surface Methodology (RSM). Using CCD, the results of physical measurement for ten conditions with two variables were obtained. The values of lightness (L), redness (a), and yellowness (b) were in the range of 36.65~49.03, 22.15~29.31, and 13.96~19.34, respectively. Lightness decreased significantly (P<0.001) and redness increased significantly (P<0.01) upon an increase in beet powder. The results of sensory evaluation showed very significant values in color (P<0.05), texture (P<0.05), flavor (P<0.01), taste (P<0.05), and overall quality (P<0.05), whereas those of the instrumental analysis showed significant values in lightness (P<0.001), redness (P<0.01), spread ratio (P<0.01), and hardness (P<0.05). As a result, the optimal sensory ratio of beet cookie was calculated for beet powder 7.75 g and butter 77.88 g.

  • This study investigated the characteristics of baking bread and cookies supplemented with taurine and the effect of taurine addition on BAC(blood alcohol concentrations) and UAC(urine alcohol concentrations). Healthy male college students were divided into two groups, the control and the taurine group. Bread was baked with the addition of 0, 2, 4 and 6% taurine and baked with the addition 0, 3 and 6% taurine. The bread containing 2% taurine showed the fastest fermentation among the 4 groups. Fermentation and oven-spring of breads baked with a taurine concentration greater than 4% of taurine disturbed. In some areas of the sensory test, the taurine supplemented bread had higher scores than the control bread. We served 6 g of taurine supplemented cookies with 1,000 $m{\ell}$ of beer to 8 students in the taurine group. After 2 hours of drinking beer, the BAC and UAC of the taurine group were found to be lower than the control group. But no difference was found in the alcohol excretion of their urine. From this study we concluded that the taurine has an effect on the detoxication of alcohol, which reduces the BAC.
