This study examined the quality characteristics of cookies comprised of various amounts of barley-sprout powder by analyzing the physico-chemical characteristics of the cookies and investigating a sensory evaluation. For the study, the cookies were cooked with the following levels of barley-sprout powder: 0%, 3%, 6%, 9%, and 12%. The results show that the moisture content of the cookies was increased in accordance with the level of barley-sprout powder and this result is the same as the spreadability factor of the cookies (p<0.001). Also, the pH and brix values of the samples decreased in accordance with the level of barley-sprout powder (p<0.001). Regarding hunter's colors, the values of L (lightness), a (redness), and b (yellowness) are significantly decreased, increasing the quantity of barley-sprout powder (p<0.001). For the textural characteristics, the results show that the hardness of the cookies decreased in accordance with the addition of the barley-sprout powder; furthermore, the results indicate a tendency whereby the DPPH-radical-scavenging activity and the total polyphenol content of the cookies were increased, thereby increasing the quantity of the barley-sprout powder (p<0.001). For the sensory evaluation, the cookies that were made with 6 % barley-sprout powder received the highest scores in terms of appearance, taste, and overall preference (p<0.05, p<0.001). This study suggests that barley-sprout powder is an excellent ingredient for improving the acceptability and functionality of cookies, and that, in relation to the flour quantity the ideal proportion of barley-sprout powder is 6%.

To evaluate the effect of dried barley sprout powder on muffins, muffins were made after they had been supplemented with barley sprout powder (0, 10, 20 and 30%(all w/w)). The moisture content, crude protein and crude lipid were reduced with an increase in barley sprout powder. The content of crude ash and crude fiber in the control group was significantly lower than those of the samples with barley sprout powder. The pH in the sample with barley sprout powder was lower than that of the control group. The highest specific gravity in the group with 30% of barley sprout powder was 0.84. No significant weight and baking loss rate changes were observed. The sample with no barley sprout powder showed the highest volume. The sample with 30% of barley sprout powder showed the highest uniformity. In color, the L-value and a-value of the control group were significantly higher than those of the other groups. Hardness, gumminess and chewiness of the control group showed the lowest value rather than the other groups. Springness and cohesiveness of the control group were significantly higher than those of the other groups. Crumb color, grass odor and bitter taste showed significant difference among groups. Acceptance of appearance, flavor, taste and total acceptability of groups with 10% and 20% of barley sprout powder did not show any significant difference when compared to the control group. Based on the above results, less than 20% of barley sprout powder would be proper to make muffins.

This study was performed to determine the optimum ratio of ingredients in the Sulgidduk with barley(Hordeum vulgare L.) sprout powder. A mathematical analytical tool was employed for optimization of the typical ingredients. The canonical form and trace plot showed the affect of each ingredient in the mixture against the final product. Mixture design showed 14 experimental points, including 4 replicates for three independent variables. The three independent variables selected for the experiment were: water($15{\sim}22%$), barley sprout powder($1{\sim}4%$), and sugar($12{\sim}19%$). The optimum responses variables such as color values(L, a, and b), instrumental texture parameters(hardness, gumminess, and chewiness), and sensory characteristics(appearance, color, smell, taste, softness, moistness, and overall acceptability) were evaluated. The Hunter colorimetric L- and a-values of the Sulgidduk decreased with an increasing amount of barley sprout powder. As more barley sprout powder was added, a higher b-value resulted. Textural hardness, gumminess, and chewiness were lowered by the addition of barley sprout powder. The optimum formulation obtained by both numerical and graphical methods showed similar results. The representative optimal ingredient ratio commonly obtained by both methods were: 18.2% water, 2.0% barley sprout powder, and 14.8% sugar.

This study examined barley sprout powder on the quality and preservation of Sulgidduk. An optimized formulation (moisture 18.2%, barley sprout powder 2.0% and sugar 14.8%) was first obtained, and then the affect if incorporating the barley sprout powder as a raw ingredients in the mixture was evaluated in terms of Sulgidduk shelf life and quality. For comparison, a control Sulgidduk sample was prepared using the optimized formulation exclusive of the barley sprout powder. After preparation the samples were stored for 3 days at $20{\pm}1^{\circ}C$. The moisture contents of both samples slightly decreased during storage: however there was no significant difference between the samples. Both samples had decreases in colorimetric L- and a-value attributable to the addition of the barley sprout powder as well as storage. Furthermore the treatment sample had increases in yellowness due to the addition of barley sprout powder and storage while the control sample had decreases in yellowness throughout the storage period. The treatment sample had increasing textural hardness, gumminess, and chewiness as the storage period increased. Finally, the treatment sample had a higher total microbial count for aerobes at the beginning of storage: however, as the storage period progressed the control had greater microbial levels. In conclusion the overall results indicate the addition of barley sprout powder has a preservaion effect on Sulgidduk. This data is expected to contribute to the commercialization of high-quality Sulgidduk products with added nutrition and extended shelf life.

This study investigated the physicochemical and antioxidant properties of sponge cakes made using different amounts (2 and 4%) of barley sprout powder (BSP) and green tea powder (GTP), respectively. The results showed that the baking loss rate of GS2 (2% green tea) and GS4 (4% green tea) was 12.39% and 11.96%, respectively in the green tea addition group, which was higher than that of the barley sprout group, but significantly lower than that of the control group at 13.34% (p<0.05). The specific volumes of the sponge cake containing barley sprout and green tea 2% and 4% were between 2.84-2.95 mL/g, which was significantly higher compared to the control group at 2.69 mL/g (p<0.05). The sugar content was significantly higher in the control group and the barley sprout addition group at 2.30°Brix (p<0.05). As for the volume index, the control group with the lowest value at 13.43 showed a significant difference compared to the addition groups. The volume index significantly decreased as the addition amount increased, measuring 14.07 in BS4 (4% BSP) compared to 14.87 of BS2 (2% BSP) in the barley sprout group (p<0.05). In cross-sectional photography, the color became darker than that of the control group as the quantum of additives increased. In terms of the DPPH and ABTS radical scavenging activity, the total phenol content, and total flavonoid content, the groups with the addition of barley sprout and green tea showed higher antioxidant activity than the control group (p<0.05).

The purposes of this study were: (1) to examine the quality characteristics of the Sulgidducks added with barley sprouts by blanching (CON), freeze-drying (FBP), hot-air drying(HBP); (2) to examine the quality characteristics of Sulgidduck such as the moisture content, the color value, the textural properties and the sensory evaluation; (3) to find the optimal ratio of barley sprouts, which were made by the three different drying methods. As a result, the Sulgidduks containing barley sprouts by CON showed a lot of significance and high correlation depending on the amounts of the barley sprout(p<0.05). As the amounts of CON, FBP and HBP increased, the L and the a values of Sulgidducks significantly decreased, whereas the b values of them increased. For the textual properties of the Sulgidducks, on the first day, the concentration in CON up to 6% showed no significant differences in the hardness, cohesiveness, springiness, and chewiness. In case of FBP, the increase in the additives caused decrease in the hardness, adhesiveness, springiness, and chewiness of the Sulgidducks on storage 0 day(p<0.05). As the amounts of HBP increased, the hardness, springiness of the Sulgidducks on the first day decreased(p<0.05). Conclusionally, 6% blanched barley sprout added group, 2% FBP and HBP were highly rated in color, flavor, bitterness, chewiness, overall acceptability and all sensory quality characteristics.

The aim of this study was to evaluate the effect of charcoal on germination and early growth of barley sprouts. Five treatments were employed based on different amount and treatment method along with control. Barley seeds were soaked in water for 8 hours. Two types of topping treatment were applied such as, charcoal: 100 g (designated as T1) and charcoal: 200 g (T2). Three kinds of mixing treatment were as follows: barley seeds were mixed with 100g of charcoal (designated as M1), with 200g of charcoal (M2), and with 300g of charcoal(M3). The control did not have any charcoal. In our finding, germination rates were observed 53.3% (control), 26.3%(T1), 36.3%(T2), 67.3%(M1), 81.7%(M2), and 79.7%(M3) at three days after inoculation (DAI). Length of radicle was found at 0.90 cm (control), 0.88 cm (T1), 0.99 cm (T2), 1.03cm (M1), 1.66 cm (M2), and 0.70 cm (M3) in 3 DAI. In addition, sprout length was found 4.5 cm (control), 10.4 cm (T1), 11.9 cm (T2), 5.7 cm (M1), 6.3 cm (M2), and 2.1 cm (M3) in 14 DAI. Fresh weight of sprouts were 0.78g (control), 1.03g (T1), 1.07g (T2), 0.96g (M1), 1.07g (M2), and 0.95g (M3). Among the treatment, topping of seeds on 200g of charcoal (T2) showed longest sprout length and fresh weight. Mixing treatments showed higher germination rates and sprout fresh weight. The results may be attributed to difference in micro-climate conditions (mostly temperature and humidity) in the growth boxes in different treatments.

The current study examined the impact of fermented barley sprout extract prepared using lactic acid bacteria (Lactobacillus sp.) in decreasing odor and increasing livestock productivity and measured the difference in the polyphenol and flavonoid contents of the extract after fermentation. Furthermore, the effectiveness of fermented barley sprout extract was evaluated through order level and production index of livestock by supplying it to a broiler house. The results showed that with fermented barley sprout extract, the polyphenol and flavonoid contents were increased significantly by 174% and 562%, respectively. When the extract was applied as an additive to drinking water in the test farm, the productivity improved by about 10%, the mortality rate was reduced by about 66%, and there was a significant decrease in odor by about 80%. Compared with the control group, the production index increased by about 21%, the feed requirement decreased by about 8%, the odor showed a decrease in the NH₃ level, and no other gas was detected. It was observed that lactic acid bacteria settle in the intestine, suppress the proliferation of bacteria that cause diarrhea and enteritis, and help digestion. The lactic acid bacteria effectively remove bad odor gases such as NH₃, Amines, H₂S and CH₄S. Such odor reduction improves productivity. Our findings provide valuable information for quality water supply, production optimization and livestock management.

The physicochemical and antioxidant properties of cookies prepared using powders of barley sprout (BS), lemon balm (LB), and green tea (GT) were studied. The same dough density was maintained in all the sample groups. The experimental group to which the natural ingredients containing antioxidants were added did not show any significant change in the appearance of cookies compared to the control. LB and GT cookies showed significantly lower hardness compared to the control (p<0.05). Control showed the lowest antioxidant effect when assessed with 2,2-diphenyl-1-picrylhydrazyl. (DPPH) and this gradually increased in the order of BS, LB, and GT. The antioxidant activity of GT was 7 times higher as compared to the control (p<0.05). The antioxidant activity assessed using 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) also showed results similar to that seen with DPPH. GT showed a significantly higher total phenol content, about 2-3 times higher compared to the control (p<0.05). GT had significantly higher total flavonoid content than that of the control (p<0.05). Thus, the addition of natural antioxidant ingredients such as sprout barley, lemon balm and specifically green tea, in the preparation of cookies, resulted in excellent antioxidant activity with similar physicochemical quality characteristics. The study suggests that it is possible to develop cookies that are competitive in terms of nutritional and physiologically active functions.
