        In this study, we developed a healthy snack using dried shrimp powder which is rich in calcium to help prevent bone disease. Different types of yanggaeng were prepared with varying ratios of dried shrimp powder; 1%, 3%, 5%, and 7%. Moisture content, color value, texture properties, and mineral concentration were measured. The L, a, and b chromaticity values showed significant differences in the 5% addition group (p<0.001). The texture properties, hardness, and adhesion decreased significantly as the amount of shrimp powder increased (p<0.001), while chewiness and elasticity significantly increased as the amount increased (p<0.001). Calcium and potassium increased significantly as the amount of shrimp powder increased (p<0.001).

        This study investigated the quality characteristics and antioxidant activity of Yanggaeng prepared with various amounts of watermelon radish flesh (WRF) powder, in ratios of 0 (control), 2.5, 5, 7.5, and 10% of the cooked white bean paste. The proximate composition, pH, sugar content, Hunter’s color values, texture analysis, and antioxidative activities of Yanggaeng were examined. Increasing the amount of WRF in the Yanggaeng tended to increase the crude ash, carbohydrate, sugar, total polyphenol, total flavonoids, and anthocyanin contents, a value, DPPH and ABTS radical scavenging activities, with decreasing the moisture and crude protein contents, L and b values, and pH. Texture measurement scores in terms of springiness, chewiness for Yanggaeng showed that 2.5% or 5.0% group was higher than those of the control group. Hardness was higher in the sample groups than in the control group. In conclusion, the results show that Yanggaeng with up to 7.0% added WRF powder can be developed as products, and there is a possibility of developing health functional snack products using WRF powder.

        The purpose of this study is to prepare low-calorie yanggaeng with reduced sugar by adding neohesperidin dihydrochalcone or NHDC (0.0125%, 0.025%, 0.05%, and 0.1%) and to compare its quality characteristics. NHDC is a high sweetener, 1,500-1,800 times sweeter than sucrose. In the sugar (oBx) and water content of the NHDC-added yanggaeng, there was no significant difference except for the sugar sample. The brightness of the yanggaeng according to the amount of NHDC added was 37.7-38.7 in the NH group, which was brighter than sugar’s (35.5). The yellowness in the NH group was -0.50 to -0.54, which was higher than the sugar’s (-0.80). The total polyphenol content ranged from 16.0-16.8 mg/100g, while DPPH radical scavenging activity ranged from 63.8-65.2. In the overall acceptability, sugar and NH3 were in the order of 6.25 and 5.25, respectively, and it was found that adding 0.05% of NHDC was desirable in replacing 50% of sugar in the manufacturing of Yanngang. Accordingly, NHDC does not have sugar level sweetness, so it does not seem easy to replace sugar completely. Research on improving sweetness by using the structural modification of NHDC is essential in the future.

        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 °Brix and showed proportional increases up to 25.0~29.7 °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.

        This study was performed to investigate the quality characteristics of Yanggaeng, including color, pH, total polyphenol contents, and antioxidant activities, with the addition of aged garlic extract (0, 3, 6, 9 or 12%), aged at low temperatures. Among the color characteristics, the lightness value decreased, and the redness and yellowness values increased, proportional to the amount of garlic extract concentrate added to Yanggaeng. The pH of Yanggaeng significantly (p<0.05) decreased according to the amount of aged garlic extract added. Total phenol contents of control (0% aged garlic extract added Yanggaeng) was the lowest, followed by 3, 6, 9, 12% aged garlic extract added to Yanggaeng (88.15, 118.39, 156.91, 208.79 mg/g, respectively). Antioxidant activities, such as DPPH and ABTS radical scavenging activity, significantly increased with increase in the aged garlic extract concentration. In the sensory evaluation for Yanggaeng, 6% aged garlic extract added to Yanggaeng had the highest score in taste, flavor, and overall acceptance. Based on these results, it is suggest that the addition of 6% aged garlic extract to Yanggaeng can be developed as a product for the elderly.

        The feasibility of incorporating licorice powder (LP) as a value-added food ingredient into convenient food products was investigated using yanggaeng as a model system. LP was incorporated into yanggaeng at amounts of 0, 2, 4, 6, and 8% (w/w) based on total weight of cooked white beans and LP. pH level decreased while moisture content and soluble solid content increased significantly with increasing levels of LP (P<0.05). In terms of color, lightness decreased while redness and yellowness increased significantly (P<0.05) with increasing levels of LP. Hardness also decreased significantly with higher amount of LP in the formulation (P<0.05). 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) and 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities were significantly elevated by LP addition, and they increased significantly as LP concentration increased in the formulation (P<0.05). Finally, consumer acceptance test indicated that the highest levels of LP incorporation (8%) had an adverse effect on general consumer preferences. In contrast, yanggaeng with moderate levels of LP (2%) is recommended based on its overall scores to take advantage of the antioxidant properties of LP without sacrificing consumer acceptability.

        The purpose of this study was to investigate the quality characteristics of white bean based Yanggaeng containing various levels of pomegranate powder (0, 2, 4 and 8%, w/w). The pH values of Yanggaeng containing pomegranate powder were found to decrease when increasing the amount of pomegranate powder. However, moisture and sugar contents were increased (p<0.05). For color values, both L and b values were reduced by increasing the amount of pomegranate powder, while a values were increased significantly (p<0.05). In textural properties, the addition of pomegranate powder resulted in the increase of hardness, chewiness and gumminess, while cohesiveness and springiness decreased. Antioxidant activities, evaluated by DPPH radical scavenging capacity, and total phenolic substances content increased when increasing the amount of pomegranate powder. Results of descriptive analysis showed that by increasing the amount of pomegranate powder, some attributes such as the intensity of the flavor, sourness, hardness and chewiness increased (p<0.05), but there was no statistically significant difference in sweetness. In a preference test, Yanggaeng containing 4% pomegranate powder appeared to be the most preferred for all attributes tested including overall acceptability. It was concluded that Yanggaeng containing pomegranate can be prepared with good sensory properties and antioxidant activities, and the addition of 4% pomegranate powder was found to be ideal.
