  • Red ginseng extract was added to Yanggaeng to determine a practical use for the herb which has medical usage and functionality. We examined the antioxidant activity and quality characteristics of Yanggaeng prepared with different amounts (as ratios of 1%, 2%, 3% to the total materials) of red ginseng extract, as well as those of commercial red ginseng Yanggaeng. The antioxidant activity of the Yanggaengs samples was estimated by the DPPH free radical scavenging activity, $ABTS^{+\cdot}$ scavenging activity, and reducing power. The antioxidant activity of the Yanggaeng increased as a result of the addition of the red ginseng extract. Levels of polyphenol compounds and flavonoids increased according to the extract concentration. The quality characteristics of the red ginseng Yanggaeng were estimated in terms of pH, sugar content, viscosity, color, texture profile analysis, and sensory evaluations. With increasing concentrations of the extract, viscosity and sugar content increased, but pH decreased. In terms of the overall palatability, color, taste, flavor, and hardness, the 3% red ginseng Yanggaeng was determined as the best among the tested samples. Also, the 3% red ginseng Yanggaeng had higher scores than the commercial red ginseng Yanggaeng.

  • The objective of this study was to investigate the quality and sensory characteristics of yanggaeng prepared with different amounts of ginseng paste. Ginseng paste was incorporated with yanggaeng at a range of different levels of 5~15% based on the total weight of water. The pH and total acidity of yanggaeng were 6.35~6.49% and 0.03~0.07%, respectively. The sugar content of yanggaeng in the control was $25.0^{\circ}Brix$ and showed proportional increases up to $25.0{\sim}29.7^{\circ}Brix$ with increasing levels of ginseng paste. In terms of the texture profile analysis, the hardness and adhesiveness of yanggaeng decreased but the cohesiveness, gumminess, and chewiness increased compared to the control and ginseng paste added treatments. In color value determination, the $L^*$ and $a^*$ values decreased but the $b^*$ value increased with increasing levels of ginseng paste. The sensory evaluation indicated that the yanggaeng contained up to 15% ginseng paste and showed similar flavor, taste, texture, and overall acceptance in the control. These results suggest that ginseng paste is an ingredient that can enhance the quality and sensory potential of yanggaeng.

  • In this study, lotus root(Nelumbo nucifera G.) and omija(Schizandrae fructus), which have been used in oriental medicine and folks remedy, were examined to apply to functional foods. We prepared yanggaeng with lotus root, sugar, oligosaccharide, agar, omija extract solution and analyzed the nutritional composition(moisture, protein, fat, ash, crude fiber, carbohydrate, free sugar and minerals). Also we investigated texture profile and evaluated sensory characteristics of developed yanggaengs and 8 commercial ones. Potassium and crude fiber contents of yanggaeng with lotus root were higher than the commercial yanggaengs. Cohesiveness, springiness and gumminess of lotus root yanggaeng were the same levels of commercial yanggaengs. Sensory evaluation with the ones, showed that the lotus yanggaeng was more desirable than the commercial ones. Yanggaeng with lotus had good scores in texture profile and sensory evaluation compared with commercial yanggaengs. These results demonstrated that lotus root hadsufficient values to use a foodstuff for yanggaeng.

  • This study was conducted to assess the quality characteristics and antioxidant activity of yanggaeng prepared with different concentrations of Viscum album extracts (VAE; 0, 1, 3 and 5%). The moisture content ranged from 37.85% to 39.38%, exhibiting no significant differences between the groups. The pH level of VAE 5% added yanggaeng was the lowest, followed in order by 3% and 1% additions. Increasing the amount of VAE in yanggaeng tended to increase acidity. The lightness value of the Hunter color system decreased based on the amount of VAE concentrate added to yanggaeng. As VAE content increased, changes in hardness, gumminess, and brittleness were all significant (p<0.05). Characteristics of cohesiveness and springiness showed no significant differences. Total polyphenol content was the highest in VAE 5% added yanggaeng. Antioxidant activities such as DPPH radical scavenging activity of the control group was 2.29%, whereas groups with added VAE ranged from 7.52~28.05%. As VAE increased, antioxidative activity also increased. In the sensory evaluation, yanggaeng addition with VAE 3% had excellent scores for bitterness, moistness, and overall acceptability. Yanggaengs with moderate levels of VAE 3% are recommended (with respect to overall preference score) to take advantage of the functional properties of VAE without sacrificing consumer acceptability.

  • The seaweed Hizikia fusiformis is rich in protein, carbohydrates, vitamins, and minerals. We investigated the physicochemical properties and antioxidant activities of yanggaeng made with agar, sugar, honey, oligosaccharide, cooked white bean paste, and different amounts (0, 1, 2, 3, 4, and 5%) of H. fusiformis powder. The proximate composition, pH, sugar content, color, texture, antioxidant activity, and sensory properties of the yanggaeng were investigated. The moisture and sugar contents of the yanggaeng did not change despite increasing the amount of H. fusiformis. The pH decreased with increasing H. fusiformis. The lightness decreased significantly, whereas the redness and yellowness increased with increasing amounts of H. fusiformis. In the texture profile analysis, the hardness, gumminess, and chewiness decreased with increasing H. fusiformis content. The antioxidant activity of the yanggaeng increased with the concentration of the H. fusiformis powder. The yanggaeng containing 2% H. fusiformis had the highest overall sensory acceptance score. The addition of H. fusiformis to yanggaeng appears to improve its quality and antioxidant activity.

  • This study developed a new yanggaeng(red bean sweet jelly) by adding Peucedanum japonicum powder from 5% to 20%. It has been evaluated its physicochemical, sensory characteristics and antioxidant activity. The DPPH radical scavenging activity of Peucedanum japonicum powder was 40.53% and the total phenolic compound content was 13.36 mg/100 g. Moisture content of yanggaeng with Peucedanum japonicum powder added 5~15% was 50.24~48.32% significantly higher than in the control group(p<0.05). The hardness of yanggaeng was $2,748.25g/m^2$in control and the PY5 and PY10 were $4,012.05g/m^2$ and $4,019.40g/m^2$ respectively, significantly higher than control(p<0.05). However, when the amount of Peucedanum japonicum powder was increased by more than a certain rate, it decreased again, as $2,155.39g/m^2$ in PY20. As a result of the acceptance test of the yanggaeng, the flavor of yanggaeng with Peucedanum japonicum powder was evaluated significantly higher than control(p<0.05), but PY20 was 5.20 not significantly difference with PY10. The overall acceptance of the yanggaeng showed the lowest value of 4.00 in the control, PY15 showed significantly high value as 7.80(p<0.05). Compared with the control, the acceptance of samples with Peucedanum japonicum powder 5~15% was higher than that of control. It was concluded that 10% and 15% of the Peucedanum japonicum powder could be added for the development of the yanggaeng. According to the above study result, to enhance the utilization of Peucedanum japonicum for developing functional food would be possible, and a new yanggaeng product by adding Peucedanum japonicum would have good potential.

  • This study examined the physiochemical and organoleptic properties of the yanggaeng fabricated with different contents of ginger powder. The moisture contents ranged between 39.85% and 47.92%. The yanggaeng made with 0.5 g of ginger powder showed the lowest moisture content of 37.04%, whereas the yanggaeng made with 1.5 g of ginger powder showed the highest moisture content of 47.92%. As for the L value, which indicates lightuess, the yanggaeng made with 1.5 g of ginger powder showed a L value of 13.92, whereas the yanggaeng made with 0.5 g showed the lowest L value of 12.35, (p<0.05). The values for redness (a value) ranged between 4.69 and 5.58, and there was no significant difference as the content of ginger powder increased. The value for yellowness, (b value) ranged between 3.19 and 2.33, and showed a significant decreasing trend as the ginger powder content increased (p<0.05). The sugar concentrations were 53.82~46.56, and decreased as the ginger content increased. The pH ranged between 6.42~6.52, and showed significant differences. As the ginger content increased, changes in hardness, adhesiveness, gumminess, and chewiness, were all significant (p<0.05). Characteristics of cohesiveness and springiness, showed no significant differences. Although there were no significant differences in color, flavor, chewiness, and hardness, there was a decreasing flavor preference as the content of ginger powder increased. There were significant differences in sweetness, moistness, and overall-preference (p<0.05). For overall-preference, the yanggaeng with 1.0 g of added ginger powder showed a high preference level. The study results implied that ginger powder may be used in fabricating yanggaeng. and a 0.5% content of added ginger powder will improve the preference level.

  • This study was conducted to investigate the effect of Chinese artichoke powder on the physicochemical properties and the sensory characteristics of yanggaeng. According to the increasing contents of Chinese artichoke powder, the $^{\circ}Brix$ value and pH levels of yanggaeng were significantly decreased whereas the moisture contents of yanggaeng was significantly increased. The result of color measurement shown that L value of groups containing Chinese artichoke powder was lower than that of control group, but a value and b value of groups containing Chinese artichoke powder were higher. Texture measurement score in terms of cohesiveness, chewiness, and brittleness for yanggaeng were significantly decreased according to the levels of added Chinese artichoke powder content. The contents of total polyphenol, DPPH radical scavenging activity, and NSA of groups containing Chinese artichoke powder were higher than those of control group. As Chinese artichoke powder increased, antioxidative activity also became bigger. Sensory evaluation scores in terms of appearance, odor, taste, texture, and overall preference of groups with 2% and 4% of Chinese artichoke powder did not show any significantly differences when compared to the control group. Based on these findings, current study suggest that addition of 4% Chinese artichoke powder was the best substitution ratio for yanggaeng.
